Health Benefits of Practicing Sun Salutations



Health Benefits of Practicing Sun Salutations
Sun salutations provide many physical and psychological benefits. This Buzzle article will tell you more...





Sun salutation is an important part of yoga. It is one of the easiest yoga routines, and an excellent way to get started with yoga if you are a total newbie. Like all yoga, sun salutation or Surya Namaskara is a whole-body exercise. A full cycle of the 12 aasanas of surya namaskara, tasks and strengthens pretty much every muscle, bone, and connecting tissue in the body.

Traditionally, surya namaskara has been performed in the morning, facing the rising sun. Though the reason for this is that the exercise is performed in honor of the Sun God, it resonates with the medical advice that exposing your body to gentle sunlight in mornings produces more vitamin D; Vitamin D is essential in building denser and stronger bones. Due to its nature as a muscle-stretching exercise, it is an ideal way to speed up recovery from earlier exercise sessions. It can be performed as a stretching routine after weight-bearing exercises. But since this is also a weight-bearing exercise in itself, it should preferably be performed on its own, or more static stretches should be added after it.

How Does Surya Namaskara Benefit You?

Here's a summary of the various health benefits imparted by practicing surya namaskara.

-#9658; Surya namaskara is an effective exercise for both muscle gain and weight loss, as well as general fitness. Like any exercise, regularly performing it helps slow down the effects of aging. It is a muscle-stretching exercise, and improves flexibility drastically.

-#9658; Unlike weight machines, which work a particular muscle to the exclusion of everything else, surya namaskara positions work the muscles, bones, as well as the ligaments/tendons in multiple areas of the body. More than 90% of the body is worked upon during a cycle of surya namaskara. This leads to better muscle coordination, and, since the connecting tissues are also strengthened, much more functional strength is achieved. Better muscular coordination also leads to much better balance, and a wider range of motion.

-#9658; The positions in surya namaskara alternate between stretching and bending the spine. In today's sedentary lifestyle, this motion is particularly beneficial to the spine. It helps relieve minor-to-moderate back problems, and also balances the chronic muscular contractions in the shoulder and the chest that arise from sitting in a chair for long hours. The cycle of alternately stretching and bending also enhances the functioning of the digestive system, and core muscles.

-#9658; Surya namaskara is, in essence, a weight-bearing exercise. Hence, it contributes to greater bone-mineral density.

-#9658; The positions in surya namaskara are accompanied by a specific breathing pattern, which increases lung capacity, teaches the body to use available oxygen efficiently, and enhances blood circulation.

-#9658; The psychological benefits of yoga have been explored and recognized by Western medicine. Regularly practicing surya namaskara is known to aid stress relief, and helps keep depression away. It promotes 'mindfulness', and, over time, imparts a calm, peaceful mentality to the practitioner. It also helps the practitioner relax in the short term.

-#9658; Traditionally, surya namaskara, like all yoga, is considered to be much more than just bodily exercise. The various positions in sun salutations are considered to have a positive effect on respective chakras in the human body. In the West, yoga has been practiced primarily as a physical exercise, and the spiritual aspect has been largely ignored. There haven't been any studies proving a connection between this exercise and the various chakras of the human body, and believing in the chakra system is completely a matter of choice. Personally, I have been practicing surya namaskara for much of the last 7 years, purely as a physical exercise.

However, the alleged positions of the various chakras correspond, with surprising accuracy, to the positions of various endocrine glands and vital organs in the human body, and sun salutations may also enhance the functioning of these glands and organs. The chakra most affected by each position can be said to be the one consisting of the organs and glands closest to the gravitational center of the body while performing the position (this is just a general rule of thumbs). Regardless of what side you are on in this debate, sun salutation unarguably has an overall positive and 'healing' effect on the whole body, and certainly doesn't harm or hinder any bodily process.

Let's look at the benefits conferred by each of the 7 distinct aasanas in surya namaskara.

Pranamasana

Although this is described as a 'resting pose', it helps you figure out the best way to balance your body. Tightened core muscles and thighs help you hold your body in a straight line, which is an oft-overlooked aspect of general fitness. It also helps you figure out any problems with your alignment.

This pose is said to have an effect on the Anahata chakra. This chakra is located in the chest, and can be said to be equivalent to the thymus and the heart.
Hasta Uttanasana

This is the first 'stretching pose'. As mentioned before, stretching your spine is one of the best things you can do for one of the most important parts of the body, before a day of sitting in a chair and hardly moving at all. It relieves the pressure on the spinal discs, acting as a deterrent against the likes of herniated discs and other spinal ailments. Stretching the spine also 'wrings out' the abdominal organs, thus improving digestion, and increases the range of motion of the shoulder and biceps/triceps muscles.

This position is said to enhance the Vishuddhi chakra. This chakra, situated in the throat, can be said to correspond with the thyroid and parathyroid glands.
Hastapadasana

This is the first bending pose. Bending forward stretches the glutes, hamstrings, and the calves, and results in stronger, more flexible legs and hips. It also increases blood flow to the brain, but since the next position reverses this effect, this is not a major advantage.

This position is said to benefit the Swadhishthana chakra. This chakra, situated in the sacrum, can be said to correspond to the gonads.
Anjaneyasana

This stretching pose imparts the same benefits as a lunge. It stretches the thighs and the groin, as well as engaging abdominal muscles and the lats. Correctly done, it also stretches the arm and shoulder muscles.

This position is said to work upon the Ajna chakra. This chakra, located on the forehead between the eyebrows, can be analogously compared to the pineal gland.
Adho Mukha Shwanasana

This step imparts roughly the same benefits as the Western exercise of plank. Sometimes, an actual plank is performed instead of this aasana. Balancing the body on the palms and toes strengthens the shoulders, wrists, core muscles, and hips. It also stretches and strengthens the calves and hamstrings, especially the former.

This position is said to enhance the previously mentioned Vishuddhi chakra.
Ashtanga Namaskara

This step is very similar to a pushup, except that the hips are raised above the body, and the knees touch the floor. Like the pushup, this position strengthens the shoulders, the core muscles, and the hips and thighs.

This position is said to better the Manipura chakra. Located in the abdomen, it can be equated to the pancreas, and the adrenal glands.
Bhujangasana

This is the 3rd stretching position in the sequence, and consequently relieves the spine, strengthens the shoulders, and enhances the functioning of the abdominal organs.

This position enhances the previously mentioned Swadhishthana chakra.
Position 8, 9, 10, 11, and 12 are simply repetitions of the positions 5, 4, 3, 2, and 1, respectively; this signifies the cyclical nature of this exercise.

Despite the universally beneficial nature of these exercises, some precaution must be taken. Surya namaskara is primarily a stretching exercise, and proper warmup should be done before starting this exercise. If not warmed up, forceful stretching of the muscles can cause serious injuries.

Like all exercises, a physician must be consulted before starting a new exercise regime, especially if you suffer from a spinal, cardiac, or respiratory condition. Pregnant women should refrain from doing the full exercise, especially after the first trimester, and should consult a trusted yoga expert for a modified version of the exercise, which can actually be beneficial to the baby's growth and the mother's well-being.

DISCLAIMER: This article should not be used as replacement for medical advice. The advice of a medical professional should always be sought before starting any exercise routine.



How Do Pregnancy Tests Work



How Do Pregnancy Tests Work
As the name suggests, pregnancy tests are done to confirm if a woman is pregnant. The following article provides information about the different pregnancy tests available and how they work...






A pregnancy test determines whether a woman has conceived or not. Although the initial symptoms of pregnancy may indicate the onset of new life within, these tests are very sensitive and can detect the pregnancy early. With home pregnancy kits readily available, women do not have to necessarily take a doctor's appointment to diagnose pregnancy.

How do Pregnancy Tests Function?

Pregnancy tests are designed to find out the presence of the hCG hormone in the urine or blood sample under consideration. Human chorionic gonadotropin (hCG) is present in women who have become pregnant. The secretion of hCG hormone begins soon after conception and its concentration increases as the pregnancy progresses. Excess hCG is eliminated out of the body through urine. So simply checking and measuring the amount of hCG present in the urine may help in pregnancy diagnosis. HCG levels that are over the 25 mIU/ml mark may indicate pregnancy. However, in case the hCG level is below 5 mIU/ml, the woman is unlikely to be pregnant.

When Can Pregnancy Tests Detect the hCG Hormone?

The placenta, that develops after the implantation of the fertilized egg, begins to secrete the hCG hormone. Pregnancy tests that check blood samples help in early detection of the hCG hormone, usually 3-4 days after implantation, or 9-16 days after fertilization, of the egg. On the other hand, a urine test is able to confirm the presence of hCG 12-19 days after fertilization. In general, a 2-3 week period after intercourse may allow you detect the hCG hormone through pregnancy tests. It is not necessary that conception (fertilization) will occur on the day of intercourse. Women who do not experience any menstrual periods after having unprotected sex should check for pregnancy. Doing the pregnancy test a week after a missed period would be ideal to get correct results. Women may receive false negative results - which means they are pregnant but the test is unable to detect it - if they take the test too soon after the missed period.

Types of Pregnancy Tests

Blood Tests
For undergoing these tests, you need to visit a doctor's clinic. There are two types of pregnancy blood tests - quantitative and qualitative. The first test detects the concentration levels of the hCG hormone in the given blood sample, indicating the duration of your pregnancy. On the other hand, qualitative tests are helpful to confirm the presence of the hCG hormone. However, you need to wait for a day or two to get the results of the pregnancy test.

Home Kits
Most women make use of a home pregnancy kit to know if they have conceived. Home pregnancy tests are cheap, convenient, and provide results within 5 minutes. Also, conducting a pregnancy test at home does not invade your privacy. The accuracy of home pregnancy kits are around 97-99%, which is good enough to consider them trustworthy. Moreover, you don't require a doctor's prescription to purchase these pregnancy kits. Although you can undergo home pregnancy tests at any time of the day, it is recommended to do the test early in the morning. This is because during this time, the hCG concentration is at its peak, making it easier to detect the presence of the hormone. It is also observed that the hCG hormone gets diluted when high amounts of fluids are consumed prior to the test.

How to Use Pregnancy Test Kits

The pregnancy test kit is nothing but a chemical strip that is capable of detecting the presence of the hCG hormone in a given urine sample. All one has to do is put a drop or two of the sample urine on the strip. After waiting for a few minutes, if you notice a plus or a line symbol on the 'result window', it indicates conception has occurred. Some pregnancy test kits digitally highlight the word 'pregnancy' in order to convey a positive result. The prepared chemical strip is made up of absorbent material, with some portion (test zone) of it covered with anti-hcg antibody-enzyme conjugates and an indicator that attach to hCG molecules only. So, when urine containing hCG hormone falls on the strip, it flows to the test zone where it gets bound to the anti-hCG bodies, causing the indicator to turn pink. The test zone turning pink is indicative of a positive outcome, thereby confirming the pregnancy.

There are several brands that sell home pregnancy test kits, but very few can detect traces of hCG hormone. So, carrying out a pregnancy test early after a missed period is not recommended. However, certain brands, such as the 'First Response Early Result Pregnancy Test' can detect hCG levels that are astoundingly 6.5 mIU/ml low. Using such products can allow you to detect hCG very early after implantation.

Medications containing hCG are likely to interfere with pregnancy tests and provide wrong results. For instance, medications such as Pregnyl and Ovidrel, that are used to treat fertility problems, contain hCG. These drugs increase the secretion of hCG in the body. Hence, the pregnancy test shows false positive in women taking these medications. Barring hCG drugs, no other medications - including contraceptive pill, painkillers or antibiotics - can influence pregnancy test results.



Proper Way to Do Sun Salutations



Proper Way to Do Sun Salutations
Sun salutation is one of the easiest and yet most effective yoga exercises. This article on Buzzle will tell you more...





Sun salutation, or Surya Namaskara, is an ancient Indian exercise comprising a specified set of yoga asanas (positions) performed in a particular sequence. In yoga practice, sun salutations hold a very important role. Beginner-level yoga students are often taught how to do sun salutations, since they are quite easy to perform, and provide long-lasting benefits.

As the name suggests, sun salutations are done in honor of the Sun god. Like all yoga, the spiritual aspect of it is accepted by choice, and if you don't believe in praying to the Sun god, you can simply look at it as an excellent exercise that strains, stretches, and betters the whole body.

6 standard asanas are incorporated in this wholesome exercise, along with a resting pose. The positions follow a general pattern of alternately stretching and bending the spine, along with variations in hand and leg positions. Along with the cycle of physical positions, there is a cyclical breathing pattern to be followed with the asanas. As a general rule, a stretching pose is accompanied by inhaling, and a compressing pose is accompanied by exhaling. All poses in this exercise are held for a few seconds before changing.

As with all yoga, the emphasis while performing sun salutations should be on natural movements, and a smooth transition between the various poses. Jerky changes can result in serious joint and muscle injuries. If correctly done, this sequence of asanas doesn't hurt at all, and is in fact beneficial in remedying minor back or joint aches. But if you have a serious preexisting spinal or musculoskeletal condition, consult your physician before starting a sun salutation routine. If you experience any pain while doing surya namaskara, take a break, or reduce the intensity of the exercise. If the pain persists, discontinue the exercise and contact your physician.

NOTE: The instructions for the poses pick up where the last pose left off, i.e. it is assumed that you are holding the previous position when starting the next one, and not doing specific poses from scratch.

Sun Salutation Sequence

1. Pranamasana (Salutation/Greeting)


Type: Resting Pose
Breathing Pattern: Exhale

Stand erect, keeping the whole body in a straight line, from head to toes. Join your heels, and spread out your toes in an angle of not more than 45°. Join your palms at chest level, keeping the forearms parallel to your body. Gently press both palms against each other, but relax if it is uncomfortable. Since this is the first pose in the asana cycle, focus your mind and concentrate on your body, and the particular regions of your body that you stress during each position.

2. Hasta Uttanasana (Raised Hands)


Type: Stretching Pose
Breathing Pattern: Inhale

Keeping the palms together, raise them above and behind your head, stretching your spine backwards to accommodate the motion. If you are a complete beginner, gauge how much you can stretch your back before going gung-ho on these motions. If you can't bend your back, stretch your hands straight above your head (no need to keep the palms together in this case), and try to lift your heels and stand on the balls of your toes.

3. Hastapadasana / Uttanasana (Standing Forward Bend)


Type: Bending Pose
Breathing Pattern: Exhale

Smoothly revert to a standing position, and stretch in the opposite direction until your hands touch your feet (don't keep the palms together). If you can't reach your feet, stretch as much as you can. Do NOT stretch beyond your capability, or 'bounce' to reach lower. If you can only reach your knees or calves, hold that position. On the other hand, if you can reach your feet easily, hold your ankles and align your forearms with your calves, or try resting your palms on the floor beside the respective foot.

4. Anjaneyasana (Crescent Moon Lunge)


Type: Stretching Pose
Breathing Pattern: Inhale

Stretch one leg back (or take a lunge forward) to assume a lunge position. Balance yourself on the heel of the front foot, and the knee and toes of the back foot. Unlike a lunge or a squat, it is okay to extend the knee of your front foot beyond the toes. Bend your upper body back, in a manner similar to the second pose. Preferably, keep your palms together. If you can't balance yourself in this position, rest your palms on the ground, keep the front foot between them, and stretch your back.

5. Adho Mukha Svanasana (Downward Dog)


Type: Bending/Holding Pose
Breathing Pattern: Exhale

Take up a plank position. Raise your hips, balancing yourself as you would while doing a plank - on your palms and toes. If you can't or don't want to raise your hip, hold a plank.

6. Ashtanga Namaskara (Eight-point Hold)


Type: Holding Pose
Breathing Pattern: Hold

Lower your body, and balance yourself on eight points of the body (asht means 'eight', and anga means 'body' or body parts): the chin (1), chest (1), palms (2), knees (2), and toes (2). Raise your hips in the air, so that the abdomen, groin, and thighs don't touch the floor. Like the previous position, if you can't or don't want to raise your hips, do a full pushup, and balance your body on the chin, chest, palms, and toes. Engage your core muscles to hold your hips in the air.

7. Bhujangasan (Rising Cobra)


Type: Stretching Pose
Breathing Pattern: Inhale

Lower your thighs. Balancing your body on your palms, lower abdomen, and legs, raise the upper body and stretch backwards as much as you can. Keep your core engaged to support the rise. Don't try to 'maximize' the stretch by craning your neck backwards excessively. If you can't stretch your back, put your arms a bit farther in front, and hold your upper body in a straight line.

The positions after this are repetitions of previous positions, performed to complete the efficient, cyclical nature of the exercise.

8. Adho Mukha Svanasana (Downward Dog)


Type: Bending/Holding Pose
Breathing Pattern: Exhale

Slowly lower your upper body. Then raise your hips, and balance yourself on your palms and toes like in step 5.

If you have lower back issues, be very careful with the transition from the 6th position to the 7th, and from the 7th to the 8th, since it can worsen the pain if performed incorrectly.

9. Anjaneyasana (Crescent Moon Lunge)


Type: Stretching Pose
Breathing Pattern: Inhale

Bring one leg forward, keeping the other one stretched behind. Repeat position 4.

10. Hastapadasana / Uttanasana (Standing Forward Bend)


Type: Bending Pose
Breathing Pattern: Exhale

Bring both legs together. Stand up, and repeat position 3. Don't cut a corner by keeping your palms on the floor and standing up, since this puts undue pressure on the hips and hamstrings.

11. Hasta Uttanasana (Raised Hands)


Type: Stretching Pose
Breathing Pattern: Exhale

Slowly raise your hands from your feet, and stretch them above and behind your head.

12. Pranamasana (Salutation/Greeting)


Type: Resting Pose
Breathing Pattern: Exhale

Return to the first position. This completes one cycle (one rep) of sun salutations. Ideally, the 12th position is supposed to be the 1st position of the second cycle, with minimal breaks. However, if you are new at this exercise, take a break of not more than 10 seconds before starting the second cycle.

Sun salutations are traditionally performed in a set of 12 reps, while facing the rising or setting Sun. Since they were traditionally performed outdoors, they could not be performed during the afternoon, with the Sun at its harshest. Also, humans on a normal circadian rhythm are primed to be more active in the mornings and evenings. The 12-rep structure enhances the cyclic nature of this exercise, with the number of positions in a single rep being the same as the number of reps performed. Beginners can start at 3 or 6 reps, and gradually progress to 12, and keep progressing to 24 and 36.

The breathing in this exercise is supposed to be done while changing positions, and not while holding a position. The breathing cycle is often difficult to implement if you are just starting out. If that is the case, you can inhale and exhale while holding the position, but keep it at the minimum required level, and practice smooth, diaphragmatic breathing. Sharp intakes of breath or forceful exhaling during a pose puts undue pressure on the core muscles. As you progress, start practicing the ideal breathing cycle.

As said before, concentrate on perfecting each pose, rather than cranking out more reps. If the described pose feels weird, make minor adjustments to the guidelines to suit your body. Make sure that you are properly warmed up before doing surya namaskara, since this is primarily a stretching exercise, and can catch muscles unawares if they are not warmed up. These exercises help maintain a great posture, an optimum build, and excellent general health.

IMP: As with any exercise, consult your physician before performing sun salutation routines. This is especially true if you have major spinal, cardiac, or respiratory issues.



Disgusting Ingredients in Food You-apos;ve Probably Eaten Today



Disgusting Ingredients in Food You've Probably Eaten Today
Ingredients derived from unpalatable sources are found in our day-to-day foods. Foodstuffs such as hamburgers, vanilla ice cream, and baked apple pie that we relish everyday may contain these disgusting ingredients.






How would you feel if you find out that some of the foods you like contain unsavory ingredients that are beyond the stretch of your imagination? Disgusted? Rightly so! Some of the ingredients printed on the label are perplexing and unpronounceable. Moreover if they are derived from 'bizarre' sources, would you feel like having them? Their inclusion may not mar the taste of the final product but that does not make them fit for consumption. These 'secret' ingredients that we ingest unknowingly may seem harmless, but are a cause for concern.

What's more surprising is that to masquerade the identity of such an ingredient, it is categorized as natural. To simply put, the food label does not give a clear idea about the ingredients that actually may be used to make the product. As though the addition of excess salt and sugar was not enough, now we bear the presence of these disgusting ingredients in processed foods. Check out these 'outrageous' ingredients found in foods that you love to eat to your heart's content.

Unsavory Ingredients in Food

Castoreum

Seeing a cup of vanilla ice cream or raspberry candies can make you go weak in your knees. However, this feeling may soon go down to the dumps when you come to know that these mouth-watering delicacies contain an animal-derived ingredient. Castoreum is a flavoring agent that is reportedly used in these food products. This flavoring agent is a yellowish secretion obtained from the castor sacs that are next to anal glands of beaver (rodent). Also referred to as beaver anal gland juice, this food additive acts as a flavor enhancer and is supposedly mixed with hard candy, fruit flavored drinks such as strawberry syrup and raspberry flavored products. Surprisingly, the nutrition column on the label of many products, names castoreum as a natural flavor enhancer. It is altogether a different matter that FEMA (Flavor and Extract Manufacturers Association) of United States has outright rejected any reports of castoreum usage for flavoring vanilla ice cream. However, FEMA does consider castoreum as a safe food additive.

Not all food companies use castoreum as a flavor enhancer. Vanilla extract, that consists of vanilla beans, sugar and ethyl alcohol, is also used as a flavoring agent. Thus, there are alternatives to castoreum that are not made from unsavory components as well as impart a good flavor to ice creams.

L-Cysteine

Use of dough conditioner in bakery products such as bread, pizza and rolls is necessary to add softness and improve their texture and elasticity. However, what would you say if you find out that dough conditioner for these products is an animal-based product? Some of the commercial brands selling bakery products are adding L-cysteine to condition the dough, but unfortunately this substance comes either from human hair, hog hair or duck feather.

Non-animal sources of L-cysteine does exist, but most food companies prefer to add animal based L-cysteine in their products as it is found to be more cost-effective than using natural sources of L-cysteine. So, the burgers, baked rolls or the baked apple pie that you eat at fast food restaurants are not only laden with calories, but also contain substances that are derived from 'bizarre' sources. Well, it seems you just got another reason to reduce the intake of these foodstuffs.

Lanolin

Chewing gum might be our favorite pastime, but it seems we may have to curb this habit considering that it contains lanolin. Lanolin that is often listed as a gum base is actually a refined oil that is derived from sheep's wool. Sheep secrete this oily matter to keep their wool soft and safe from the ravages of climate. Also known as sheep sweat, lanolin plays a key role to soften your bubble gum.

Ammonium Sulfate

Ammonium sulfate, a fertilizer, has become an indispensable ingredient of sandwich breads and buns. While conventional farming does lead to miniscule presence of fertilizers in our day-to-day foods, if ammonium sulfate is added externally to make the bread fluffy, it can be frightful. Ammonium sulfate contains nitrogen, which helps in proper fermentation of yeast, the primary constituent of bread. Various popular food brands that sell sandwiches and burgers often add ammonium sulfate to maintain the consistency of the product.

Viruses

Yes, viruses (bacteriophages) are actually added in processed meat to protect it from listeriosis-causing bacteria. Listeriosis has been a cause for concern in United States as approximately 500 people die yearly due to this bacterial infection. The bacteria are found in ready-to-eat meat, cold cuts or lunch meat. Packaging substandard meat has been the main reason behind the spread of listeriosis in the United States. In order to control the rising cases of listeriosis, FDA has sanctioned the use of viral spray on processed meat.

The spray is a solution containing 6 strains of viruses that are capable of destroying the bacteria. Meat products prior to packaging are often treated with this spray to keep them safe from listeria contamination. The good news is that bacteriophages are usually not a health hazard and do not infect humans.

Isinglass

Looking forward to a glass of beer after a tiring day at work? Think again! Isinglass, which is extracted from the bladder of sturgeon (a type of fish), is used for brewing beer. Fermenting yeast is an important process in making beer. After the process is over, yeast tends to appear floating in the liquid. Fining agents like isinglass are then added to facilitate removal of yeast. It clarifies and provides stability to the beer and ensures that the drink does not appear cloudy.

Although, after clarification, the beer is filtered again, some amount of isinglass still remains. Not all brands use isinglass or other animal products to produce beer. Non-filtered beer such as the cask ale, tend to use animal products for processing beer. Usually, beer that are made in Britain use isinglass during the filtration process.

Carmine

The unusual red color that you see on your favorite smoothies, candies, juices, and dairy-based beverages such as strawberry milk is an animal-based product. It is a red dye obtained from a particular bug known as cochineal. The meat industry also has been adding carmine to make their products more visually enticing. Carmine imparts a characteristic crimson/pink color to the food or beverage, thereby making it look vibrant and attractive. So, how is carmine extracted from the insect? Firstly, the insect is dipped in hot water so that it dies. The insect stores a significant amount of carmine in the abdomen. So, the process involves crushing the abdomen and heating its contents at a very high temperature to remove the coloring agent (carmine). In case carmine is added to the food, it may be listed as E120, cochineal extract or hydrated aluminum chelate of carminic acid. Interestingly, carmine is also found in cosmetic products such as lipstick and perfumes.

Many argue that 'since insects contain substantial amount of proteins and vitamins, so what's the harm?' However, they forget that processed parts of insects (as found in carmine) do not provide any goodness of nutrition.

Shellac

The same product is used for beautifying wood as well as for making fruits look more pleasing to the eye. Shellac, a viscous substance, sourced from the secretion of Kerria lacca bug is used for polishing wood furniture, but surprisingly is also applied to candies and fruits. So, the unusually red-colored apples might look attractive but the glossy, shinier appearance comes from the application of shellac. The coating of shellac is said to improve the shelf life of fruits. This is the best example of how far the food industry would go to woo the customers.

Pig Skin

Now, vegans certainly won't be happy to read this. Gelatin desserts, especially Jell-O, is primarily made from pig or beef skin. Its primary constituent, collagen (a type of protein that provides strength and elasticity to the skin) is derived from pig's skin.

Wood Powder

Shredded cheese that is sprinkled on a variety of American dishes contains cellulose, which is a combination of grated wood and plant fiber. So, the shredded cheese that you happily add to your recipe to make the dish 'delicious' actually contains wood powder. Well, this is just the tip of the iceberg as quite a few dairy products such as low-fat ice creams, yogurt and even crackers, muffins, breads, puddings, etc. contain powdered cellulose.

Cellulose displays anti-caking properties, hence its addition prevents cheese slivers from sticking together to form a large clump. The extensive use of cellulose has also been attributed to its ability to increase the longevity of processed food.

Other Gross Components That FDA Allows in Your Food

These are actually contaminants but since they are found regularly in food items, this Buzzle article has listed them under gross components of food products. Due to substandard quality control techniques, these contaminants tend to get mixed in the food during processing.

Maggots

Hey! This cannot happen. Well, this is what you may scream if you find maggots in a can of mushrooms. However you will be surprised to know that FDA legally allows 19 maggots or 74 mites in approximately 100 grams of canned mushroom. Although maggot therapy does help in cleaning skin ulcers effectively, one still cannot imagine consuming them. Instead of canned ones, using fresh mushrooms for cooking would be a sensible option.

Rodent Hair

Eating a piece of chocolate may help to alleviate your mood. However, you will be shell-shocked to know that it might contain rat hair. Legally, chocolate companies are not culpable if 1 rat hair in every 3.5 ounces of chocolate is found. Moreover, FDA's action level allows 60 insect fragments in a hundred gram sample of chocolate.

Similarly, FDA does not consider it a health hazard if 11 rodent hairs are found in a 50 gram pack of ground cinnamon. Also, there is nothing "wrong" (as per FDA criteria) if every pound of popcorn has 2 rodent hairs.

Insect Fragments

The peanut butter that you spread everyday on your morning toasts may contain unsavory ingredients such as animal hair. Again, FDA allows around 30 insect fragments or 1 rodent hair in 3.5 ounces of peanut butter. If this was not enough, macaroni and noodles sold in packages may also contain insect contamination. For instance, 225 grams of packaged noodles is allowed have around 225 insect fragments or 4 rodent hairs.

Canned green vegetables such as frozen broccoli, Brussels sprouts and asparagus pack a powerful nutrition punch, but unfortunately they may also contain insects. For instance, FDA does not mind if 100 grams of frozen Brussels sprouts contain around 60 thrips, mites or aphids.

FDA Criteria

You might be wondering why FDA allows such unpalatable ingredients in the first place. The point is, these permitted ingredients are definitely not pleasing to your taste buds, but this does not mean that they are detrimental to health. To put it simply, something that is unsavory cannot be assumed to be inedible, if its quantity present does not exceed a permissible limit. The FDA's 'Defect Level Handbook' clearly mentions that these 'faulty' ingredients are not harmful to health if the contaminant quantity is not more than the regulated FDA guidelines.

Also, the size of the insect fragment that occur in some canned vegetables is in microns. So, the concentration of contaminants is very miniscule as compared to the size of the food sample under consideration. It would be wrong to conclude that every chocolate or a can of mushrooms you purchase will contain these contaminants. It all depends on the quality standards adopted by a particular food brand. Maintaining high standards while processing food will ensure zero adulteration of the final product.

All in all, if the ingredients are taken from reliable sources, checked for authenticity and this is complemented by good manufacturing practices, there is no reason why you shouldn't get a pure, unadulterated product.

On-road vehicles are responsible for 44% of all carbon dioxide emissions in the US, one-third of all nitrogen oxide emissions and one-quarter of all volatile organic compound emissions.
- Center for Transportation ExcellenceEveryone encounters traffic, either vehicular or denizen traffic. The feeling of being stuck in a place full of vehicles or people gets overwhelming for many individuals, and is the main cause of stress-related disorders cropping up in today's time.

At the 49th Annual Conference on Cardiovascular Disease Epidemiology and Prevention, the American Heart Association stated, "People who have had a heart attack are likely to report having been in traffic shortly before their symptoms began." This statement was from a German study, that determined that exposure to traffic was a key contributor to heart attacks.

When talking about traffic woes, we also need to take into consideration the pollution that we are exposed to. Breathing in toxic emissions from bikes, cars, trucks, and buses harm our lungs making us targets to various respiratory-related diseases. Given below is an in-depth exposition on how traffic affects our health and what we can do to retard some of these effects to live a longer and healthier life.

Health Effects of Traffic
Aches and PainsImagine yourself being tied down in one place, with your arms holding a wheel in front of you, but no scope for movement, with horns blaring in the background and poisonous smoke being sent your way, well, that is your situation when you are driving in traffic.Due to your confinement, you tend to neglect your posture, and end up slouching in the car seat. While driving in a slouched position, pressure comes on your back and neck. The neck muscles are interrelated to your back and shoulders. Back pain is often due to poor posture which can have a negative effect on your health.
In the long run, this is not good as it makes a difference on your appearance, and also makes you prone to ailments like spondylitis, frozen shoulder, etc.
Your bad posture also puts stress on the joints of your elbows and knees, causing pain and fatigue to these areas of your body.
You might be wondering how driving in traffic puts stress on your joints? When you are driving in traffic, you are constantly shifting between the accelerator and brake (in automatic transmission cars), and clutch, brake, and accelerator (in manual transmission cars). This constant shifting puts pressure and stress on your knees, causing knee-related problems and aches.
The same goes for the elbows, if the car seat is not at a comfortable distance from the steering wheel, your elbows are constantly straight, or locked. This position is very bad for the ball-and-socket joints of the elbow.
What can you do: You can counteract these ill effects and posture problems, by sitting upright and having a support for your lower back and neck. Adjust the position of your seat in such a way that you can drive at ease without any discomfort. The backrest of the seat should be straight up, and not pulled down too much. These methods take off a lot of stress and help you drive the right way.
Risk of Heart DiseaseProlonged exposure to traffic pollution, is dangerous to your heart, and is associated with an increased risk of heart diseases.According to a study presented at the EuroPRevent 2013 congress in Rome, people who are exposed to fine particle matter (PM) air pollution derived from traffic pollution, for a prolonged period of time, are at an increased risk of developing atherosclerosis.
Dr Hagen Kälsch, from West-German Heart Center in Essen, Germany explained that this study was conducted to establish whether the risk of heart diseases is associated with traffic noise or pollution, or both. He confirmed that long-term exposure to fine particulate matter air pollution and traffic noise are both linked with the risk of cardiovascular diseases.
The heart is a delicate organ and needs to be treated with care. Pollution, fluctuating stress levels, loud noises, inhalation of harmful gases, etc. are reasons why the condition of the heart may weaken and deteriorate with time. These factors are significantly associated with the risk of heart attack.
Dealing with inconsistent and rash drivers increases your stress levels, as you constantly get irate with the way they ride or drive, or jittery when they cut and zoom past you when you are driving peacefully. This can take a toll on your cardiovascular health.
What can you do: Regular exercise in fresh air, relaxing by getting massages, eating the right food, etc. can help your heart recover from the stress that it has gone through due to the chaotic traffic conditions. Deep breathing and meditation also help in reducing stress levels.
Respiratory ProblemsExposure to heavy traffic implies exposure to poisonous gases that are emitted by vehicles. It is believed that the transportation sector in the US, is responsible for a quarter of the greenhouse gas emissions.Our lungs are like sponges, soaking in everything that is inhaled by our respiratory system. The smoke coming out of the tailpipes of cars, bikes, and buses have hydrocarbons, particulate matter, nitrogen oxides, carbon monoxide, sulfur dioxide, benzene, acetaldehyde, butadiene, and carbon dioxide, which present a serious threat to human health.
Prolonged exposure to vehicular traffic emissions can cause various respiratory diseases like, bronchitis, whooping cough, asthma, etc.
Another lung-related ailment, that can be blamed on long-term exposure to the hazardous pollutants emitted from vehicles in traffic, is cancer. Emissions from diesel vehicles are said to increase the risk of lung cancer.
What can you do: There are ways to avoid breathing in polluted air. If you can, avoid driving in parts of your town with heavy traffic congestion. However, if you find yourself driving through such areas, roll up your car windows to minimize exposure to harmful toxins. If you plan to go out for a stroll or run, do it in a place where you get loads of fresh air. Eat food that are rich in antioxidants, and exercise regularly so that your immune system is strong enough to fight off potential threats to your health.
Other ProblemsTraveling from one place to another is inevitable. Given below are some other potential health risks associated with long-term exposure to traffic pollution.The impact of traffic jams on the brain may be a causative factor in DNA and gene alteration.
Being exposed to harmful pollutants, leads to vitiated brain capacity and risk of brain damage.
Brain lesions, low IQ, lack of retention and concentration, epilepsy, migraines, blurry vision, etc. are the negative effects of pollutants on our central nervous system.
Long-term exposure to neurotoxins which are present in the smoke emitted from vehicles, causes degeneration, and in some extreme cases, irreparable damage to the central nervous system.
Fatigue, anxiety, and irritability, are also faced by thousands of commuters.
Exposure to high volume traffic, brings about mental and physical exhaustion.
Dealing with strangers on an everyday basis, especially in traffic, makes you lose your patience and cool. You actually feel like getting out of your car and giving everyone around you a piece of your mind.
You get irritated easily, you are snappy, and sometimes even get anxiety attacks.
Many a time you feel agitated and anxious while traveling. This may be because you worry that the traffic will make you late, which increases your stress levels.
What can you do: Cover your mouth and nose with a scarf so that you do not breathe in the harmful smoke directly. Keep your cool while driving, by listening to music that you enjoy. Get a car freshener that soothes your mood (pleasant fragrances have the power to change moods drastically, from bad to good!). Turn your car into a comfort zone and remind yourself that getting agitated over other people is never going to help you, it will just make things worse.
Travel and traffic are two things that are absolutely unavoidable, that is why we should try to be as comfortable as possible, to be stress-free and illness-free!

How Do Pregnancy Tests Work



How Do Pregnancy Tests Work
As the name suggests, pregnancy tests are done to confirm if a woman is pregnant. The following article provides information about the different pregnancy tests available and how they work...






A pregnancy test determines whether a woman has conceived or not. Although the initial symptoms of pregnancy may indicate the onset of new life within, these tests are very sensitive and can detect the pregnancy early. With home pregnancy kits readily available, women do not have to necessarily take a doctor's appointment to diagnose pregnancy.

How do Pregnancy Tests Function?

Pregnancy tests are designed to find out the presence of the hCG hormone in the urine or blood sample under consideration. Human chorionic gonadotropin (hCG) is present in women who have become pregnant. The secretion of hCG hormone begins soon after conception and its concentration increases as the pregnancy progresses. Excess hCG is eliminated out of the body through urine. So simply checking and measuring the amount of hCG present in the urine may help in pregnancy diagnosis. HCG levels that are over the 25 mIU/ml mark may indicate pregnancy. However, in case the hCG level is below 5 mIU/ml, the woman is unlikely to be pregnant.

When Can Pregnancy Tests Detect the hCG Hormone?

The placenta, that develops after the implantation of the fertilized egg, begins to secrete the hCG hormone. Pregnancy tests that check blood samples help in early detection of the hCG hormone, usually 3-4 days after implantation, or 9-16 days after fertilization, of the egg. On the other hand, a urine test is able to confirm the presence of hCG 12-19 days after fertilization. In general, a 2-3 week period after intercourse may allow you detect the hCG hormone through pregnancy tests. It is not necessary that conception (fertilization) will occur on the day of intercourse. Women who do not experience any menstrual periods after having unprotected sex should check for pregnancy. Doing the pregnancy test a week after a missed period would be ideal to get correct results. Women may receive false negative results - which means they are pregnant but the test is unable to detect it - if they take the test too soon after the missed period.

Types of Pregnancy Tests

Blood Tests
For undergoing these tests, you need to visit a doctor's clinic. There are two types of pregnancy blood tests - quantitative and qualitative. The first test detects the concentration levels of the hCG hormone in the given blood sample, indicating the duration of your pregnancy. On the other hand, qualitative tests are helpful to confirm the presence of the hCG hormone. However, you need to wait for a day or two to get the results of the pregnancy test.

Home Kits
Most women make use of a home pregnancy kit to know if they have conceived. Home pregnancy tests are cheap, convenient, and provide results within 5 minutes. Also, conducting a pregnancy test at home does not invade your privacy. The accuracy of home pregnancy kits are around 97-99%, which is good enough to consider them trustworthy. Moreover, you don't require a doctor's prescription to purchase these pregnancy kits. Although you can undergo home pregnancy tests at any time of the day, it is recommended to do the test early in the morning. This is because during this time, the hCG concentration is at its peak, making it easier to detect the presence of the hormone. It is also observed that the hCG hormone gets diluted when high amounts of fluids are consumed prior to the test.

How to Use Pregnancy Test Kits

The pregnancy test kit is nothing but a chemical strip that is capable of detecting the presence of the hCG hormone in a given urine sample. All one has to do is put a drop or two of the sample urine on the strip. After waiting for a few minutes, if you notice a plus or a line symbol on the 'result window', it indicates conception has occurred. Some pregnancy test kits digitally highlight the word 'pregnancy' in order to convey a positive result. The prepared chemical strip is made up of absorbent material, with some portion (test zone) of it covered with anti-hcg antibody-enzyme conjugates and an indicator that attach to hCG molecules only. So, when urine containing hCG hormone falls on the strip, it flows to the test zone where it gets bound to the anti-hCG bodies, causing the indicator to turn pink. The test zone turning pink is indicative of a positive outcome, thereby confirming the pregnancy.

There are several brands that sell home pregnancy test kits, but very few can detect traces of hCG hormone. So, carrying out a pregnancy test early after a missed period is not recommended. However, certain brands, such as the 'First Response Early Result Pregnancy Test' can detect hCG levels that are astoundingly 6.5 mIU/ml low. Using such products can allow you to detect hCG very early after implantation.

Medications containing hCG are likely to interfere with pregnancy tests and provide wrong results. For instance, medications such as Pregnyl and Ovidrel, that are used to treat fertility problems, contain hCG. These drugs increase the secretion of hCG in the body. Hence, the pregnancy test shows false positive in women taking these medications. Barring hCG drugs, no other medications - including contraceptive pill, painkillers or antibiotics - can influence pregnancy test results.



Proper Way to Do Sun Salutations



Proper Way to Do Sun Salutations
Sun salutation is one of the easiest and yet most effective yoga exercises. This article on Buzzle will tell you more...





Sun salutation, or Surya Namaskara, is an ancient Indian exercise comprising a specified set of yoga asanas (positions) performed in a particular sequence. In yoga practice, sun salutations hold a very important role. Beginner-level yoga students are often taught how to do sun salutations, since they are quite easy to perform, and provide long-lasting benefits.

As the name suggests, sun salutations are done in honor of the Sun god. Like all yoga, the spiritual aspect of it is accepted by choice, and if you don't believe in praying to the Sun god, you can simply look at it as an excellent exercise that strains, stretches, and betters the whole body.

6 standard asanas are incorporated in this wholesome exercise, along with a resting pose. The positions follow a general pattern of alternately stretching and bending the spine, along with variations in hand and leg positions. Along with the cycle of physical positions, there is a cyclical breathing pattern to be followed with the asanas. As a general rule, a stretching pose is accompanied by inhaling, and a compressing pose is accompanied by exhaling. All poses in this exercise are held for a few seconds before changing.

As with all yoga, the emphasis while performing sun salutations should be on natural movements, and a smooth transition between the various poses. Jerky changes can result in serious joint and muscle injuries. If correctly done, this sequence of asanas doesn't hurt at all, and is in fact beneficial in remedying minor back or joint aches. But if you have a serious preexisting spinal or musculoskeletal condition, consult your physician before starting a sun salutation routine. If you experience any pain while doing surya namaskara, take a break, or reduce the intensity of the exercise. If the pain persists, discontinue the exercise and contact your physician.

NOTE: The instructions for the poses pick up where the last pose left off, i.e. it is assumed that you are holding the previous position when starting the next one, and not doing specific poses from scratch.

Sun Salutation Sequence

1. Pranamasana (Salutation/Greeting)


Type: Resting Pose
Breathing Pattern: Exhale

Stand erect, keeping the whole body in a straight line, from head to toes. Join your heels, and spread out your toes in an angle of not more than 45°. Join your palms at chest level, keeping the forearms parallel to your body. Gently press both palms against each other, but relax if it is uncomfortable. Since this is the first pose in the asana cycle, focus your mind and concentrate on your body, and the particular regions of your body that you stress during each position.

2. Hasta Uttanasana (Raised Hands)


Type: Stretching Pose
Breathing Pattern: Inhale

Keeping the palms together, raise them above and behind your head, stretching your spine backwards to accommodate the motion. If you are a complete beginner, gauge how much you can stretch your back before going gung-ho on these motions. If you can't bend your back, stretch your hands straight above your head (no need to keep the palms together in this case), and try to lift your heels and stand on the balls of your toes.

3. Hastapadasana / Uttanasana (Standing Forward Bend)


Type: Bending Pose
Breathing Pattern: Exhale

Smoothly revert to a standing position, and stretch in the opposite direction until your hands touch your feet (don't keep the palms together). If you can't reach your feet, stretch as much as you can. Do NOT stretch beyond your capability, or 'bounce' to reach lower. If you can only reach your knees or calves, hold that position. On the other hand, if you can reach your feet easily, hold your ankles and align your forearms with your calves, or try resting your palms on the floor beside the respective foot.

4. Anjaneyasana (Crescent Moon Lunge)


Type: Stretching Pose
Breathing Pattern: Inhale

Stretch one leg back (or take a lunge forward) to assume a lunge position. Balance yourself on the heel of the front foot, and the knee and toes of the back foot. Unlike a lunge or a squat, it is okay to extend the knee of your front foot beyond the toes. Bend your upper body back, in a manner similar to the second pose. Preferably, keep your palms together. If you can't balance yourself in this position, rest your palms on the ground, keep the front foot between them, and stretch your back.

5. Adho Mukha Svanasana (Downward Dog)


Type: Bending/Holding Pose
Breathing Pattern: Exhale

Take up a plank position. Raise your hips, balancing yourself as you would while doing a plank - on your palms and toes. If you can't or don't want to raise your hip, hold a plank.

6. Ashtanga Namaskara (Eight-point Hold)


Type: Holding Pose
Breathing Pattern: Hold

Lower your body, and balance yourself on eight points of the body (asht means 'eight', and anga means 'body' or body parts): the chin (1), chest (1), palms (2), knees (2), and toes (2). Raise your hips in the air, so that the abdomen, groin, and thighs don't touch the floor. Like the previous position, if you can't or don't want to raise your hips, do a full pushup, and balance your body on the chin, chest, palms, and toes. Engage your core muscles to hold your hips in the air.

7. Bhujangasan (Rising Cobra)


Type: Stretching Pose
Breathing Pattern: Inhale

Lower your thighs. Balancing your body on your palms, lower abdomen, and legs, raise the upper body and stretch backwards as much as you can. Keep your core engaged to support the rise. Don't try to 'maximize' the stretch by craning your neck backwards excessively. If you can't stretch your back, put your arms a bit farther in front, and hold your upper body in a straight line.

The positions after this are repetitions of previous positions, performed to complete the efficient, cyclical nature of the exercise.

8. Adho Mukha Svanasana (Downward Dog)


Type: Bending/Holding Pose
Breathing Pattern: Exhale

Slowly lower your upper body. Then raise your hips, and balance yourself on your palms and toes like in step 5.

If you have lower back issues, be very careful with the transition from the 6th position to the 7th, and from the 7th to the 8th, since it can worsen the pain if performed incorrectly.

9. Anjaneyasana (Crescent Moon Lunge)


Type: Stretching Pose
Breathing Pattern: Inhale

Bring one leg forward, keeping the other one stretched behind. Repeat position 4.

10. Hastapadasana / Uttanasana (Standing Forward Bend)


Type: Bending Pose
Breathing Pattern: Exhale

Bring both legs together. Stand up, and repeat position 3. Don't cut a corner by keeping your palms on the floor and standing up, since this puts undue pressure on the hips and hamstrings.

11. Hasta Uttanasana (Raised Hands)


Type: Stretching Pose
Breathing Pattern: Exhale

Slowly raise your hands from your feet, and stretch them above and behind your head.

12. Pranamasana (Salutation/Greeting)


Type: Resting Pose
Breathing Pattern: Exhale

Return to the first position. This completes one cycle (one rep) of sun salutations. Ideally, the 12th position is supposed to be the 1st position of the second cycle, with minimal breaks. However, if you are new at this exercise, take a break of not more than 10 seconds before starting the second cycle.

Sun salutations are traditionally performed in a set of 12 reps, while facing the rising or setting Sun. Since they were traditionally performed outdoors, they could not be performed during the afternoon, with the Sun at its harshest. Also, humans on a normal circadian rhythm are primed to be more active in the mornings and evenings. The 12-rep structure enhances the cyclic nature of this exercise, with the number of positions in a single rep being the same as the number of reps performed. Beginners can start at 3 or 6 reps, and gradually progress to 12, and keep progressing to 24 and 36.

The breathing in this exercise is supposed to be done while changing positions, and not while holding a position. The breathing cycle is often difficult to implement if you are just starting out. If that is the case, you can inhale and exhale while holding the position, but keep it at the minimum required level, and practice smooth, diaphragmatic breathing. Sharp intakes of breath or forceful exhaling during a pose puts undue pressure on the core muscles. As you progress, start practicing the ideal breathing cycle.

As said before, concentrate on perfecting each pose, rather than cranking out more reps. If the described pose feels weird, make minor adjustments to the guidelines to suit your body. Make sure that you are properly warmed up before doing surya namaskara, since this is primarily a stretching exercise, and can catch muscles unawares if they are not warmed up. These exercises help maintain a great posture, an optimum build, and excellent general health.

IMP: As with any exercise, consult your physician before performing sun salutation routines. This is especially true if you have major spinal, cardiac, or respiratory issues.
