Anti-aging wonder?

There is a naturally occurring substance that has been receiving a whole lot of attention over the last several years. It’s a polyphenol antioxidant called resveratrol found in foods like peanuts, some berries, grapes and consequently, wine. In a new study researchers examined the effects of resveratrol on rats with colon cancer.

The rats were divided into four groups according to treatment?one that received a chemical to induce cancer (called 1,2-dimethylhydrazine, or DHM for short), one that received DHM and trans-resveratrol, one that received only trans-resveratrol, and finally, one that received no treatment to serve as a control.

Over the course of this 30-week study, researchers had two major goals: to evaluate the short-term effect that this powerful compound would have on DNA damage and to evaluate the long-term effect it would have on membrane lipid peroxidation (the process by which free radicals cause damage to cell membranes). In addition, the researchers measured the levels of circulating antioxidants.

The results? Rats supplemented with trans-resveratrol showed significantly less white blood cell damage than those that received DHM alone. What?s more, those that received trans-resveratrol for the full 30 weeks also showed a marked increase in several key antioxidant enzymes?including superoxide dismutase, catalase and glutathione reductase?along with other antioxidant factors like vitamin C, vitamin E and beta-carotene. Finally, this group of rats also showed a noticeable decrease in markers of dangerous lipid peroxidation.1

In the end, the study authors? conclusion couldn?t be more clear?or promising, for that matter?stating ?results indicate that DMH-induced DNA damage and oxidative stress were suppressed/prevented effectively by chronic resveratrol supplementation.?

So does this study show that daily supplementation of resveratrol will keep you young? No. However, resveratrol has a whole lot of good things going for it backed by a lot of research and should be considered as part of ones daily regimen. Vitamin Research Products

Another benefit males might be most interested in has to do with estrogen. Resveratrol acts as a potent estrogen antagonist. This means it hinders the negative effects of estrogen.

In higher concentrations, it acts as an aromatase inhibitor. Resveratrol has been shown to hinder the transformation of testosterone to estrogen. As ones estrogen goes up the testosterone goes down. This means that it help to halt the body’s natural aging process of whittling away at your Testosterone.

Why is this good for men? Because if a substance hinders the transformation of testosterone to estrogen or estradiol, not only does it prevent the malicious effects of estrogen like a decrease in muscle and strength and an increase of body fat, it increases your level of testosterone, which translates into an increase in strength and muscle.

Low testosterone not good for male bone

Low testosterone levels may boost the risk of fractures for men over 60, an Australian study finds.

The researchers tracked 609 men (average age 72.6) between 1989 and late 2005.

The University of Sydney researchers collected information about the men’s bone mineral density, lifestyle habits, and blood levels of testosterone and estradiol (an estrogen).

During the study period, 113 men suffered low-trauma fractures (caused by a fall from standing height or lower). Of those men, 25 suffered multiple fractures.

There were a total of 149 fractures, including 55 vertebral, 27 hip, 28 rib, six wrist and 16 upper- and 17 lower-extremity fractures.

The risk of fracture was much higher among men with low testosterone levels, the team found.

Even after adjusting for a variety of potential risk factors, low blood levels of the two hormones “were associated with overall fracture risk,” the study authors concluded. Fracture risk was associated “particularly with hip and non-vertebral fractures,” they noted.

The findings are published in the Jan. 14 issue of the journal Archives of Internal Medicine.

Higher protein consumption yields muscle size, strength and overall health

Protein is by far the single most important supplement/nutrient you can consume in your quest for size and strength. Just the mere mention of it, however, gives most doctors and dietitians an anxiety attack. I?m sure you?ve heard much of the unfounded non-sense: ?All you need is food; supplements aren?t necessary.?, ?Too much protein can lead to kidney and liver problems.?, ?An average person can only absorb 30 ? 40 grams of protein at one sitting.?, ?Vegetable protein is just as good as meat, fish or milk protein.?, ?Eating more protein will make you fat.?, and so on and so on. There is not one reputable, reliable study to support any of these previous statements, and I cannot tell you how tired I am of dealing with this groundless garbage.

Protein repairs and maintains everything in our bodies from hormones to muscles to bones. Proteins are made up of building blocks called amino acids. There are nine essential amino acids. Essential meaning we have to ingest these for survival because our bodies cannot manufacture them. Many researchers now believe we have many other amino acids that should be considered ?conditionally essential?, because of their significance and our inefficiency at producing them. These include; glutamine, arginine, cysteine, taurine, glycine, tyrosine and proline.

If your protein intake or quality is low your body will get the essential aminos it needs from its most abundant storage system, muscle tissue. Knowing this explains why strict vegetarians, especially vegans, have a lower percentage of muscle than dairy, meat and fish eating humans and a harder time building muscle or strength in the gym. The quality of protein inherent to a vegetarian diet, especially vegans?, is dismal at best and a few studies have shown vege males have less testosterone then their meat eating counterparts; especially true if soy is part of their diet. What else should you expect consuming food inferior to human physiology?

Consciously consuming a diet low in protein has no benefits; is not based on good science, and merely a matter of ignorance. There are two things that begin with the letter ?P? that I would never cut back on; one is protein; the other ends in ?Y?. Having said that, how much protein should one consume? The International Society of Sports Nutrition, in a 2007 position statement, concluded that bodybuilders and strength/power athletes require just under a gram of protein per pound per day; consistent with my recommendation of 1 g/lb of lean body weight. However, if you train intensely, which is how you should train, empirical data suggests you may need upwards of 1.5g/lb to 2g/lb. Have no fear; this extra protein will not make you fat.

Protein, in and of itself has little to do with getting fat; protein consumption is inversely related to fat accumulation. The more protein you eat the more fat you burn as fuel. Protein consumption is directly related to thermogenesis and satiety through multiple mechanisms. It?s what you eat more than how much you eat that will determine how lean strong and muscular you will get.

A calorie is not a calorie. The assertion that macro-nutrients are all processed the same between individuals is just foolish. This is the basis for the calorie theory. A calorie of a carbohydrate does not equate to a calorie of protein when being metabolized in our bodies. Protein calories are not likely to be stored as fat as compared to carbs, because protein requires more energy to metabolize and assimilate and has numerous functions. Carbs are simply an energy source, and if not used as fuel, they are stored as fat without much effort; carbs also stimulate the release of high amounts insulin, the fat storage hormone. The higher your insulin, the more fat you’ll store. Keeping your insulin levels low is a key to becoming and staying lean. As an added bonus, protein helps to stimulate the secretion of glucagon, which helps mitigate the fat storage effects of insulin.

Calorie theory doesn’t hold water

In my latest Q & A I answer questions about supplement usage for raising testosterone and gaining muscle while offering advice to a reader who lost prescription drug coverage. I also delve into the “calorie theory,” below, explaining how burning food in a calorimeter just isn’t the same as eating it. Yum.

Q: Hi Mike,
First I just wanted to say I find you articles very informative, and am glad you’re debunking the myths of saturated fat and cholesterol causing heart disease. These myths just won’t die.

I was curious though as to what you suggest someone do to get shredded. I believe you have mentioned that you believe reducing carbs is the best way to get lean, as Vince Gironda did? But do you believe in calories in vs calories out as well? If you are cutting weight do you reduce your food as well (same as reducing calories) or do you just drastically reduce or eliminate carb sources of food (grains, fruits, veggies, dairy)?

Thanks for your help,

A: Antaeus,
A calorie is the amount of heat needed to raise 1 kilogram of water 1 degrees Celsius at sea level. What does this mean? A Double Whopper with cheese contains 990 calories. If we were to burn this burger, it would produce 990 calories. This is enough energy to raise 990 kilograms of water 1 degree Celsius.

Calories are measured in sealed device called a “calorimeter” which locks in heat of burning food. A small vacuum of water is contained above the food. Once the food is completely burned, the temperature of the water is measured. The rise in temperature will determine the amount of calories. The calorimeter can show the total amount of energy of a Big Mac, but it cannot account for what the body doesn’t absorb, or the energy used in the digestion and assimilation of it.

Does counting calories consumed matter, or even necessary when trying to lose weight? In a word, NO. Counting calories is completely inaccurate and a waste of time. Our bodies do not process food like a calorimeter. Our bodies do not use all the food we consume as energy, nor do we assimilate it all in the same manner. More-over, we do not store food we consume with the same efficiency. The assertion that macro-nutrients are all processed the same between individuals is just foolish. This is the basis for the calorie theory.

The best thing one can do is eliminate as much sugar and processed foods from their diet as they can. Eat as many whole natural foods as you can, including: beef, fowl, fish, vegetables, raw dairy products and some fruit. The following Nutritional principles will help anyone on their way to getting leaner.

Plan your meals in advance.

Prepare your food in advance.

Do not starve yourself. Eat when you?re hungry and stop when your full.

Eat at least 4 times per day.

Eat protein with every meal.
