Resveratrol, Fact or Fiction?

The latest fad in the unending search for the cure to the natural aging process is Resveratrol, which is found in the skin of red grapes and as a constituent of red wine. It came to scientific attention only four years ago as a possible explanation for the "French Paradox" - the low incidence of heart disease among the French people, who eat a relatively high-fat diet.

Resveratrol is a phytoalexin produced by several plants that is sold as a nutritional supplement, which were first sourced from ground dried red grape skins and grape seeds (sometimes from residual byproducts of winemaking), but are now primarily derived from the cheaper, more concentrated Japanese knotweed.

Since supplements are not regulated by the FDA, what do we really know about the effects [especially the long term] of Resveratrol? Well, not much. According to Melissa Q.B. McElderry, M.S., R.D.:

Laboratory tests have clearly demonstrated that resveratrol may help prevent cardiovascular disease and cancer. However, there are several reasons why recommending a population-wide increase would be premature.

- First, little is known about the absorption and clearance of resveratrol, the identities of its metabolic products, or its effects on the liver. A study in rats showed that resveratrol is absorbed in the gut and has a high affinity for the heart and liver.
- Second, the research on resveratrol has focused on its short-term effects and has been dominated by in vitro studies on non-human models.Third, its role as a potentiator of breast carcinomas may significantly limit its use, even for its "proven" benefits.
- Finally, its main dietary source is red wine. Not only is its concentration in wine extremely variable, but recommending increased consumption of red wine to boost resveratrol intake could certainly do more harm than good. In spite of any beneficial aspects, red wine and other alcoholic beverages pose health risks that include liver damage and physical addiction.

The health-food industry is claiming that resveratrol is the wine component responsible for the "French Paradox." While taking resveratrol pills is certainly safer than heavy consumption of red wine, supplementing with unproven substances is generally unwise. At this point, occasional use of red wine seems far more prudent.

Hi all,

Please be aware that Resveratrol is so minuscule in your everyday foods and wine, that it get's flushed out easily by your system.

Look for a supplement if you are serious about this. Please read this scientific study to understand why Resveratrol in wine or everyday foods will probably be to small for good health:

I have been searching for the perfect curl cream for most of my 33 year lifespan and I believe I

have found it in this product! I have a lot of fine naturally curly hair and this cream is great. Keep in mind, however, that a little goes a LONG way! For example, my hair is down past the middle of my back

and I use approximately 2 teaspoons. I apply it when my hair is wet, right out of the shower, and then just scrunch with a towel and that is all the product I need! It is a little costly, but this bottle

lasts me about 4 months.

I never thought it could be possible. I own about 7-9 hair straighteners from cheap to deluxe. Not one of them could

penetrate my thick, curly hair enough to do anything other than heat up the cuticle and make sizzling noises. This iron is going to change my life. I spent 700 on ionic straightening, and this iron works

better!!!! If you spend any amount of time wielding a heavy blow dryer, forget about it. I used this iron on Air-dried, curly hair. I wish I could upload a digital photo- I look like a hair commercial.

Unbelievable but true!!! I LOVE IT!!!
