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.
Most people who workout love training their arms; rarely do you here of somebody skipping their arm workout. You never see somebody walking around with large muscular legs and skinny arms. In fact, it’s just the opposite. This is in no small part due to the fact that no other body part exemplifies strength and development, and is the envy of others like a muscular pair of arms. In the following article I walk you through one way to properly bang your your triceps to new growth.How does form and function relate to triceps training? Let’s look at what the triceps actually do. The triceps extend, or straighten, the arm. For example, without your triceps it would be virtually impossible to grab a beer from the fridge. That would truly be a tragedy. Without triceps, your arm would be in a constant flexed state. This having been said, exercises that stress movement only at the elbow (such as triceps pressdowns) are solid movements. However, I am starting to see less and less multi-joint movements used in workouts. Examples of multi-joint movements for the triceps would be close grip bench presses, dips and a few others. These exercises involve not only the elbow joint but the shoulder joint as well.
