Wrinkles
An inevitable consequence of the aging process is the loss of elasticity in the skin that we often take for granted when we are young. This loss of firmness is amplified by competition diets and training which can trim storage fat stores to the point that female competitors’ faces look positively skeletal. My eye is trained to scan a person’s face for areas of lipoatrophy, elastosis, rhytids, shifting of malar fat pads, etc….in other words, sunken, sagging, drooping, wrinkled skin. The degree of elastic breakdown and loss of soft tissue fullness that I see in an average fifty year old is something I commonly see in many female competitors as young as their late 20’s. This process only gets worse over time unless the competitor is willing to do something to prevent progression.

What can a competitor do once her skin has started this dreaded sagging process?

There are laser treatments available which help to resurface and refine the skin and which can also tighten the skin somewhat. However, these treatments are often too expensive for competitors, especially when considering all the costs associated with competing. Another viable and cost-effective solution to the issue of loosening skin is a chemical peel. There are many different types of chemical peels available, ranging from very light glycolic acid peels to an aggressive TCA (trichloroacetic acid) peel. One composite peel (phenol, TCA, salicylic acid and Retin-A) which is my personal favorite is the Vi-Peel which is well tolerated, painless, and confers a good tightening effect on the skin.

Another wonderful option to correct the loss of volume in the face and add structural support is fillers. There are a number of hyaluronic acid based fillers available now (Restylane, Perlane, Juvederm, Belotero) which last 6 months to a year. Radiesse is another natural filler option which is comprised of calcium hydroxylapatite. Radiesse also acts as a biostimulator, stimulating cells in the skin to produce collagen over time. Another wonderful feature of Radiesse is the fact that it lasts 18 months or more.

If you have wrinkles in the forehead and around the eyes, Botox and Dysport are excellent treatments and will last for 3 to 6 months.

If you are in the Los Angeles area, I offer filler and Vi-Peel treatments. Please go to my medical website for more information: http://www.staceynaito.com

Why Zinc Is So Important

zinc
Zinc is a vital mineral which is found in every tissue in the body due to its involvement in cell division. In the world of fitness and bodybuilding, zinc has a number of roles, including maintenance of normal hormonal levels, proper endocrine function, body composition, energy levels, optimal physical performance and protein synthesis. Thus it is crucial to maintain normal levels of zinc in the body when training or prepping for a competition.

Zinc is highly concentrated in meat, dairy and some seafood. This is why vegetarians most commonly suffer from zinc deficiency. So how can you tell if you suffer from a zinc deficiency? Common symptoms include an altered sense of taste which leads to cravings for sweets and salty foods. Other symptoms of zinc deficiency include low energy, infertility, low libido, memory problems, poor immunity and diarrhea.

A relatively easy way to test yourself to see if you are deficient in zinc is to do a taste test. Take 1 to 2 teaspoons of zinc sulfate (you can get this at health food stores) and add to a cup of water. If it tastes just like water, you are very zinc deficient. If you experience a slightly metallic taste, you are moderately zinc deficient. If it is strongly metallic and unpleasant, you most likely have normal zinc levels. Please bear in mind that this test is never as accurate as a blood test, but at least it will give you an idea of what your levels are.

For those of you who want to know the specific health benefits of zinc, here is a list of benefits.

Enhances Strength and Athletic Performance:

Zinc plays a major role in anabolic hormone production which makes it a key player in optimizing athletic performance and strength. When zinc levels in the body are normal, more growth hormone and insulin-like growth factor-1 is released, which result in enhanced muscle growth and performance. Researchers have also noted that zinc enhances the conversion rate of androstenedione to testosterone, which improve strength gains during the recovery phase.

Enhances Reproductive Health and Fertility in Both Men and Women:

The cells of the male prostate require an extremely high concentration of zinc for proper function. To give you an idea of how much zinc is necessary in the prostate, male prostate tissue requires ten times more zinc than other cells in the body for normal function. There is a correlation between low zinc levels in men and increased risk of developing prostate cancer and infertility. There is also evidence to support the link between low zinc levels and low libido. Another implication with low zinc levels is its importance in maintaining optimal testosterone levels. Men with low zinc also tend to have low testosterone, which puts them at greater risk of andropausal symptoms.

In women, proper levels of zinc are essential for egg maturation and ovulation. Zinc also optimizes utilization of estrogen and progesterone and regulates their levels. During pregnancy, zinc plays a vital role in ensuring proper cell division in the growing fetus and helps to prevent premature delivery.

Essential For Taste, Smell and Appetite:

Zinc activates areas in the brain that process information from taste buds in the mouth and olfactory cells in the nasal passages. In addition, levels of zinc in the plasma influence taste preference and appetite. Many programs which treat anorexics use zinc to revive taste and appetite.

Makes Skin, Hair and Nails Healthy:

Zinc accelerates skin cell renewal which is why it is commonly used in diaper rash creams, acne treatments and creams which are used to treat dermatitis. It has strong anti-inflammatory properties and has a soothing effect on rashes, burns and blisters. Some shampoos contain zinc to help prevent dandruff. What you may not know is that zinc is important for healthy hair and that low zinc levels can cause hair loss, dull and thin hair, and loss of pigmentation.

Essential For Vision:

Zinc is found in high concentrations in the retina, but this level declines with advancing age, precipitating age-related macular degeneration which is characterized by a partial or complete loss of vision. Zinc also has a protective effect against the development of cataracts and night blindness.

Supports Cardiovascular Health:

Zinc is vital to normal cardiovascular function. When levels of zinc are low, the endothelial layer in blood vessels becomes inflamed and accumulates cholesterol deposits, both of which increase one’s risk of heart disease. Low levels of zinc can amplify the negative cardiovascular effects of diets which are high in fat and cholesterol, whereas adequate levels of zinc will inhibit the progression of heart disease.

Increases Insulin Sensitivity:

The presence of zinc is essential for normal function of most hormones, including insulin. Zinc binds to insulin and aids in storage in the pancreas as well as release of insulin in the presence of serum glucose. In addition, zinc is found in the enzymes which enable insulin to bind to cells so that glucose can be utilized for fuel, a process better known as insulin sensitivity. Why is this important? If zinc levels are low, enzyme levels drop, insulin sercretion drops and glucose remains in the bloodstream, a process which can lead to diabetes if it is chronic.

Improves Mood:

Dopamine, a chemical in the brain which boosts mood and energy, is partially regulated by zinc, so zinc once again plays an important role in the body. There is also evidence to support the theory that the presence of zinc boosts serotonin levels in the brain.

Supports Immune Function:

Zinc supports T cell function and is thus strongly tied with combating inflammation. T cells are responsible for mounting an immune response to invaders such as bacteria or viruses.

Has Potent Antioxidant Effect:

Zinc can remove toxins from the body and prevent accumulation of harmful compounds in tissues. This mechanism has a protective effect against the development of cancers, especially in the prostate, ovaries, pancreas, breast and colon. In addition, zinc prevents the buildup of heavy metals in the brain such as aluminum, which has been closely linked with Alzheimer’s disease.

If you suspect that you are deficient in zinc, you can supplement daily with 20 to 30 milligrams.

Why You Should Add Curcumin To Your Diet

http://www.rxmuscle.com/blogs/the-lab-supplement-school/7143-why-you-should-add-curcumin-to-your-diet.html
Curcumin diagram
Antioxidants have become a hot topic in combating disease in recent years, and the list of these substances has grown thanks to extensive research which has been conducted and disseminated to the public. A particularly powerful antioxidant is curcumin. Curcumin, an extract which is derived from turmeric, has been used in Asian curries for many centuries and has also been used for treatment of arthritis and other health conditions. Only recently has curcumin received attention from the United States regarding its remarkable benefits as a potent antioxidant.

Perhaps the most exciting potential benefit of curcumin is that it may help to prevent and treat cancer by inhibiting cancer cell growth and the growth of blood vessels which feed into tumors. There is some speculation that curcumin can prevent cancer cells from multiplying and is also capable of causing self-destruction of cancer cells. As if this wasn’t enough, there is a possibility that curcumin may prevent Alzheimer’s Disease by decreasing the accumulation of amyloid which characterizes this disease.

Here is a list of other benefits which curcumin confers:
· Accelerates wound healing
· Acts as a cleanser for the liver
· Regulates metabolism and assists in weight loss
· Reduces LDL cholesterol and raises HDL levels
· Decreases severity of inflammatory skin disorders such as psoriasis
· Acts as a natural painkiller

If these reasons are not enough to compel you to add curcumin supplementation into your meal plans, consider the fact that curcumin reduced the COX-2 enzyme in the body, thus decreasing the pain and swelling of arthritis. In fact, recent studies revealed that curcumin was even more effective than ibuprofen (Motrin, Advil) in its anti-inflammatory effects. One particular study in Italy which was conducted on 50 patients, all of whom had confirmed knee osteoarthritis, found a 58 percent decrease in reported overall pain and stiffness as well as an improvement in physical functioning among the curcumin group versus the control group.
Curcumin bottle
How To Take Curcumin
Some individuals may prefer to ingest curcumin in the form of straight turmeric powder which can be added to meals or tea. However, I prefer to take curcumin in capsule form. If you opt for the capsule version, look for formulations which contain piperine, or black pepper extract. Piperine augments the gastrointestinal absorption of curcumin. Recommended daily dosage is 400 to 600 milligrams per day. For acute flare-ups of arthritis or other musculoskeletal pain, you can double the dosage until the acute phase abates.

Supplements Women Need

Supps for women
The number of nutritional supplements which are available today can be pretty intimidating to those who are not familiar with the benefits which they confer on those who take them. If you also consider the performance supplements which are marketed to fitness-minded individuals, and which are marketed mostly to men, women are often left bewildered. Since it is my aim to address the issues of women in this article, I will not discuss general supplements such as multivitamins, CLA, fish oil, CoQ10 or the like. Rather, I will focus on supplements which have demonstrated efficacy in treating female-specific woes.

Biotin: This substance promotes growth of healthy hair and nails and is something I have taken daily for many years. Though I have horribly thin nails (and continue to suffer from them despite biotin), my hair has actually gotten considerably thicker in the past ten years, and I honestly believe that biotin has played a large role with respect to my hair health. Another great benefit of biotin is the demonstrated effect it has on regulation of blood glucose. I recommend taking the maximum dose possible, 5,000 micrograms per day.

Calcium: Calcium is a mineral which is a critical component of bone health. There are three mistakes I see people making when taking this supplement:
1. Taking it without Vitamin D or magnesium – Both Vitamin D and magnesium must be present in order for the body to be able to absorb calcium.
2. Taking it on an empty stomach – Calcium is best absorbed when taken with food.
3. Taking large doses at one time – The body is unable to absorb much more than 500 milligrams of calcium at one time. Since the general daily dose in women of childbearing age is 1,000 mg, supplementation should be broken up into 2 doses of 500 milligrams each per day.

DHEA: Dehydroepiandrosterone (DHEA) is a precursor hormone which is produced in the adrenal glands which is later converted to sex hormones such as estrogen and testosterone. Levels of DHEA fall with advancing age and can also decline as a result of exposure to stress. Signs of declining DHEA include stress, fatigue, memory loss, depression, dry skin, and decreased libido. Women are struggling with infertility may also find that DHEA will increase their fertility by promoting hormonal balance and ovulation. I generally feel that any woman over the age of 35 would benefit from supplementation with DHEA at 5 to 15 milligrams per day.

Folic Acid: Many women are aware that supplementation with folic acid decreases the risk of neural tube defects in a developing fetus, but not many know that folic acid has been proven to lower blood pressure in women and prevent development of hypertension. A daily dose of 800 micrograms is advised.
ALA: Alpha lipoic acid, or ALA for short, is effective in regulating blood glucose, optimizing carbohydrate consumption and reducing sugar cravings. Effective dose ranges are between 100 to 200 milligrams, taken two to three times daily.

Chromium Picolinate: Chromium picolinate can decrease sugar cravings and is effective at regulating blood glucose. A dose of 200 micrograms three times daily is optimal.

Vanadyl Sulfate: This is another supplement which can curb sugar cravings. Take 10 milligrams three times daily.

Phosphatidylserine Complex: This supplement supports the adrenal glands during stressful times. Those with poorly functioning adrenal glands should not take this supplement. A daily dose of 200 milligrams taken earlier in the day is recommended.

Melatonin: Melatonin is well known for its effectiveness in balancing out sleep patterns and treating insomnia. This is due to the fact that it reduces cortisol levels (cortisol is known as the stress hormone). Women who suffer from infertility should not take this as it can aggravate the condition. Start with 0.5 milligrams shortly before bedtime and slowly increase the dose by 0.5 mg increments ever few days until you get the desired effect. Do not take more than 5 mg in a dose. Some experts recommend that melatonin only be taken in the short term for isolated insomnia bouts.
Natural Woman
B-Complex – B-complex formulations consist of the following: B complex capsule contains the following vitamins: folic acid, thiamine (B1), riboflavin (B2), niacin (B3),panthothenic acid (B5), pyridoxine (B6), cyanocobalamin (B12) and biotin. This complex supports memory, improves mood, decreases anxiety and combats the effects of stress. It also boosts metabolism, thus increasing energy. I have encountered remarkable responses to B-complex in people who have suffered from depression and who did not respond to prescription antidepressants. I recommend 100 mg per day.

GLA: Gamma-linoleic acid can be very effective in treating the symptoms of PMS, such as menstrual cramps and breast tenderness, especially when taken in tandem with magnesium and vitamin B6. Take 500 to 1,000 milligrams per day.

Magnesium Glycinate: This is a highly bioavailable form of magnesium which helps not only with PMS but also with hot flashes which some menopausal women experience. Recommended dosage is 250 milligrams one to three times daily, and should be taken with food.

Vitamin B6: Vitamin B6 is effective in mellowing the symptoms of PMS, menopause, and morning sickness associated with early pregnancy. It is also effective for depression, acne, and bladder inflammation. Take between 50 to 600 milligrams per day in two to three divided doses.

Cranberry Extract: This is an excellent supplement for good urinary tract health, as it renders the inner bladder walls slippery so that bacteria are unable to adhere to them. Any women who have recurrent bladder infections should take this supplement at a daily dosage of 400 to 500 milligrams.

Diindolylmethane: This extract is found in cruceiferous vegetables such as broccoli and cauliflower and supports healthy estrogen metabolism by optimizing breakdown of excess estrogen. A great formula is DIM-Plus by Nature’s Way. Take two capsules per day.

Should You Block Cortisol Production?

cortisol
Cortisol’s Functions

Cortisol has gotten a bad rap in recent years due to its nickname, the “stress hormone”. What occurs during times of excessive emotional stress? The adrenal glands respond by producing more cortisol in an effort to provide more energy and a higher pain threshold which is in keeping with the “fight-or-flight” response you may be familiar with. Normally, cortisol levels are at their highest in the morning then decrease progressively throughout the day, but if your body is placed under excessive stress, it may produce abnormally high levels of cortisol which disrupt this natural pattern. The resulting elevation in cortisol stimulates the metabolism of carbohydrates and fats and also triggers insulin release. These activities can result in an increased appetite and uncomfortable hunger pains. Blood glucose levels also rise as a result of excessive cortisol release, and if that glucose is not used for energy, it will be stored in the body’s fat reserves, particularly in the fat cells of the abdominal region.

An alarming consequence of excess cortisol release as a result of stress is the damage to the hippocampus and potential memory loss which can occur over time. Several studies have discovered that about one fourth of the hippocampus cells in the brain are lost as we age. Since the hippocampus is responsible for giving feedback to the cerebral cortex in order to prevent production of excess cortisol, such feedback is impaired and could lead to memory loss over time.

However, while it is true that cortisol is responsible for responding to stressful situations, it is also essential for a number of important functions in the body, including regulation of blood pressure, glucose metabolism, immune system support, memory support and regulation of blood sugar. Keeping cortisol release at a balanced and normal range is the key to optimizing its beneficial effects.

Catabolism, Anabolism and Cortisol

Cortisol is a potent catabolic agent and has been shown to cause significant loss of muscle mass in sedentary individuals. When cortisol is released into the bloodstream, it binds to receptors on muscle cells and activates the ATP-dependent ubiquitin/proteasome pathway which causes the body to literally consume its own muscle tissue. It’s a disturbing thought, but the upside is that weight training is effective in counteracting some of cortisol’s direct catabolic actions. The strange paradox is that training both reduces cortisol’s direct catabolic effects and increases the body’s secretion of the substance. Cortisol also slows the body’s anabolic drive by inhibiting the release of testosterone, human growth hormone and insulinlike growth factor 1. Thankfully, weight training once again blocks this anti-anabolic action to some extent, but this block only occurs in the trained muscles.

Another bizarre paradox with cortisol is found with protein absorption. Eating any meal will trigger cortisol release, but proteins are the most potent cortisol releasers. Cortisol release can be blocked by administering alpha-1-blockers before a protein meal, but this will also adversely affect protein absorption. What this boils down to is that cortisol must be released in order to properly assimilate proteins. Keep in mind that protein-induced cortisol release is very brief, while cortisol released as a result of stress persists for a much longer period of time.

Controlling Cortisol Release

A certain level of cortisol secretion is normal. However, if you are interested in controlling excessive cortisol release, you may want to consider taking certain supplements. The most prudent manner in which to do this is to get a blood test beforehand which will determine whether you actually have abnormally high cortisol levels.

GlutamineComplex300L-glutamine: Athletes who supplement with L-glutamine are well aware of its mass building and reparative effects, but L-glutamine also halts cravings for simple carbohydrates, thus aiding in stabilizing blood sugar in individuals who have high cortisol levels.

Theanine: Theanine is naturally found in green tea and has been studied for its calming effects on the nervous system. It works by triggering dopamine and gamma aminobutyric acid (GABA) release, which serve to protect the hippocampus.

L-lysine and L-arginine: Combination oral supplementation of these two amino acids have been proven to reduce anxiety and restore cortisol to basal levels.

B-Complex Vitamins: All of the B vitamins work synergistically in adrenal hormone production, especially vitamin B-6, pantothenic acid and niacin. Not only do they support adrenal hormone production, they also protect against the effects of excess cortisol.

Vitamin C: When the body is placed under stress, free radicals are produced which cause the body to use up vitamin C as a protective mechanism for cells. Since we are unable to produce our own vitamin C, it must be ingested regularly. In fact, vitamin C intake should be increased during stressful times.

Zinc: Stress-related cortisol surges will often trigger sugar cravings which, when indulged, may result in a zinc deficiency due the fact that sugar binds with zinc and is excreted. However, individuals who supplement with zinc and refrain from sugar indulgences benefit from a protective effect which zinc confers. One study in particular, “Zinc Acutely and Temporarily Inhibits Adrenal Cortisol Secretion in Humans” by J. Brandao-Neto et al in the January 1990 issue of the journal “Biological Trace Element Research”, administered zinc to some subjects and placebo to the control group. The group which was given zinc supplementation showed an acute drop in cortisol levels compared with the control group.

Magnesium: Studies by Dr. Hans Selye revealed that when the human body shifts from an acute “fight or flight” reaction to a chronic stress response, the high levels of cortisol and norepinephrine result in magnesium depletion. When the body is deficient in magnesium, one becomes predisposed to panic attacks which lead to more stress and more depletion. Studies have also shown that 80 percent of the American population is deficient in magnesium. By supplementing with magnesium, one can boost serotonin production and provide protection against the harmful effects of excess cortisol.

ZMA: ZMA, which stands for Zinc monomethionine aspartate and Magnesium Aspartate, is a popular sports supplement which is comprised of zinc, magnesium and vitamin B6. The proportion of ingredients usually seen is 20-30 mg zinc, 400-500 mg magnesium and 10 mg of vitamin B6. This supplement meets the body’s magnesium requirement, and the zinc and vitamin B6 allegedly increase strength levels.

Pregnenalone: Pregnenalone is a precursor to progesterone and DHEA. Since progesterone has a protective effect against the effects of estrogen and cortisol, and since DHEA causes cortisol levels to fall, pregnenalone can be an effective supplement in controlling cortisol excess.

Phosphatidylserine: This phospholipid is an essential building block for cells which is extremely effective in reducing cortisol levels in response to physical stress. Phosphatidylserine can also have a positive effect on one’s mood.

Bodyfuse D-MassTestosterone Boosters: These substances can moderate the release of cortisol in response to exercise.

Growth hormone boosters: These substances also control exercise-induced cortisol release while leaving basal cortisol release unaffected.

Carbohydrate drinks: When a workout is lengthy, blood glucose levels fall, resulting in hypoglycemia which triggers the release of cortisol. Consuming a carbohydrate beverage can prevent this drop in blood glucose while also maintaining insulin at a high level.

To Suppress, Or Not To Suppress…Cortisol, that is:

Many of you are aware that cortisol can simultaneously cause degradation of protein and impair protein synthesis. However, there is a danger in taking supplements to inhibit cortisol release if your basal cortisol levels are already low. When basal cortisol levels are below normal, metabolism is disrupted, blood sugar drops and glycogen stores are diminished. Low cortisol levels also cause blood pressure to plummet along with a decrease in cardiac output. Diminished cortisol also causes hyperactivity in the melanocytes which produce skin pigment, precipitating dark discoloration.

If that isn’t enough, low cortisol results in impaired immune response, weakness and dehydration. When infection, excessive sweating or surgical trauma occur in such an environment, an adrenal crisis can occur. If such a crisis is pronounced, a whole host of symptoms can manifest, a number of which are life threatening. The most severe of these symptoms are loss of consciousness, low blood pressure, seizures, shock and coma.

As stated before, it is a good idea to check your cortisol levels before taking any type of supplement which is designed to control cortisol release.

High Fructose Corn Syrup

Corn Syrup
Corn sugar, or high-fructose corn syrup (HFCS) as it is more commonly called, is the most common sweetener which is used in processed foods and beverages. In fact, HFCS comprises more than 40 percent of caloric sweeteners added to foods and beverages and is the sole caloric sweetener in soft drinks in the United States. It is adored by the food industry because it is extremely sweet, incredibly cheap, easy to transport and keeps foods moist. Like its chemical cousin table sugar (sucrose), it has raised eyebrows in the research world and prompted a growing body of studies which examine the manner in which the body processes it. The general consensus is that consumption of large quantities of any type of sugar is closely linked to dental cavities, obesity, malnutrition, and increased triglycerides. One study which was published in Metabolism Journal discovered that individuals who drank a beverage sweetened with HFCS had fructose blood levels five grams higher than those consuming a beverage sweetened with table sugar. This may not seem like much, but when you consider the cumulative effects, HFCS becomes a much more insidious dietary villain.

Fructose and GlucoseLet’s examine the composition of HFCS. This substance contains from 43 to 55 percent fructose with the remainder as glucose. In contrast, sucrose is 50 percent fructose and 50 percent glucose. Both are quite similar except when it comes to chemical bonds. When HFCS is made from cornstarch, the fructose molecules are not bound to other sugar molecules, while with sucrose, every fructose molecule is bound to a glucose molecule. When sucrose is ingested, it must undergo an extra metabolic step before the body can use it. With HFCS, the body reacts to the fructose readily. The problem is that fructose has no effect on glucose levels and insulin release (in other words, it skips glycolysis) and thus will not trigger the release of leptin (the hormone which signals your body to stop eating when it is full) nor create a feeling of satiety. This can lead to a higher caloric intake with a corresponding body weight increase. Basically, HFCS tricks the body into thinking it’s hungry when it may already be full.

Foods Containing Large Levels of HFCS
· Regular soft drinks
· Salad dressings
· Breakfast cereals
· Frozen yogurts
· Canned soups
· Canned fruits (if not in their own juice)
· Jarred and canned pasta sauces
· Bread
· Fruit-flavored yogurts
· Pancake syrups fruit juice and fruit drinks
· Popsicles
· Ketchup and barbecue sauces

Make sure to check ingredient listings, especially with the foods listed above, and try to avoid HFCS whenever possible.

Protein Denaturing And What It Means For You

http://www.rxmuscle.com/blogs/the-lab-supplement-school/6456-protein-denaturing-and-what-it-means-for-you.html

protein denaturing
Proteins are comprised of amino acids arranged like beads on a string (primary structure) which are then folded upon themselves by means of hydrogen bonds (secondary, tertiary and quaternary structures). This intricate folding can be very complex, conferring specificity which defines a protein’s biological activity. If such higher structures are disrupted, such as by temperature extremes, altered salt concentration or changes in pH, a protein’s biological activity can be reduced or completely obliterated.

When most proteins are heated beyond 41 degrees Celsius (105.8 degrees Fahrenheit), the bonds are broken, thus resulting in denaturing of proteins. When you consider the fact that normal body temperature is 37 degrees Celsius or 98.6 degrees Fahrenheit, not much heat is required to break down a protein. Most stoves have broiling air temperatures up to 500 degrees Fahrenheit, with the surface temperatures of food reaching higher temperatures as a result of direct radiation from the heating elements. In essence, normal cooking practices heat proteins well above the temperatures at which they become denatured.

In addition to denaturing, cooking temperatures can cause cross-linking of some proteins, best exemplified by hardening of bread or eggs during the cooking process. This reduces the digestibility of the proteins, but it is important to consider that the majority of those proteins is absorbed and utilized by the body. Most whey protein has been processed at temperatures exceeding 160 degrees Fahrenheit or 72 degrees Celsius, qualifying it as hydrolyzed protein. However, despite the fact that the peptide bonds in the protein are broken during pasteurization, denatured protein still contains all of the amino acids that are found in unhydrolyzed protein and which provide the building blocks for muscle.

What this translates to is the fact that there is still nutritional benefit to be gained from denatured protein despite the argument by some that such proteins are useless. During the critical post-workout window, the body needs protein in order to repair and build muscle. Most of this is absorbed and utilized by the body, with a small portion excreted as waste which is often characterized by a particularly pungent “protein bomb” odor.

Why have I brought up the subject of denatured protein? Because I have heard people argue that hydrolyzed whey protein is useless because it is not bioactive. It seems to me that the considerable muscle mass found on individuals who ingest large amounts of whey protein flies directly in the face of such a short-sided argument. Furthermore, I do not believe that the baking process to which whey protein used in high protein breads is subjected poses any greater risks on the constituent amino acids themselves since they are already hydrolyzed to begin with. Until I see an individual who shows no increase in muscle mass despite proper weight training and sufficient protein intake which relies heavily on whey protein sources, I will continue to hail hydrolyzed whey protein as an excellent source of protein for those who are trying to gain muscle.

Great Bombshell Poster From Team U 2013 When I Went Pro

bombshell TU

The titles here aren’t completely correct here. I was the Over 35 B Champion as well, with a First Place finish to complement my Over 40 B First Place finish and my Overall Title in Over 40, but because I had already won my Pro Card, Second Place finisher Lindsay Oxford got her Pro Card as well. I guess that is why they decided to make it sound like Lindsay Oxford had won her class.
