Resveratrol, Anti-Aging Nutrient in Red Wine and Grape Juice
Liz LipskiJanuary 20
Resveratrol first came to public attention when the researchers noted that people in France have less heart disease but eat so much fatty food, and called it the French Paradox. Could it be the red wine? And what in the wine: Resveratrol!
Resveratrol is a powerful, antioxidant phenol that is found in grapes. The highest concentrations are found in red wine, but purple grape juice, the skin of young unripe red grapes, and grape seeds also have significant amounts. It’s also found in small amounts in peanuts.
Resveratrol has been shown to have anti-aging effects and to boost athletic performance (in mice, rats and primates). It also is anti-oxidant, anti-cancer, and helps promote weight loss, is anti-infl ammatory, has cholesterol lowering abilities, and increases insulin sensitivity. Studies also show that Resveratrol may also lower the risk of colon cancer and slow the progression of Alzheimer’s disease.
Current research shows that resveratrol’s powerful protective effects come from its ability by activating a group of genes called sirtuins (also called silent information regulator proteins, specifically SIRT-1 and SIRT-2. ) Sirutins protect our DNA, extend life span, protect our cells from radiation, and speed up cellular repair.
It’s not known what the optimal amount of resveratrol is, but based on animal research, most of us would benefit from between 5 mg daily for prevention, and 40 to 150 mg daily therapeutically. Although many more studies on people need to be done, there doesn’t seem to be any negative effects from taking these amounts daily. Based on the French Paradox studies, drinking one glass of red wine daily can be protective. A glass supplies about 1 mg of resveratrol.
This may be a supplement you’d like to try, you may look for it in a multivitamin, or you may want to drink your one glass of wine daily, or drink more purple grape juice, or eat the seeds you find in your grapes.
The Pearl: Resveratrol is just one more reason to put more colorful food into your daily diet.
