Unfortunately, the level of resveratrol in red wine is so low that it is not particularly effective in promoting weight loss. “You would need to drink hundreds of glasses of red wine or take hundreds of pills of nutraceutical products per day,” said Dr Christoph Westphal, CEO of Sirtris. Using studies of diabetic mice, animals on high levels of resveratrol were able to exercise twice as long as the control group (not taking resveratrol), lost weight and became more sensitive to insulin, thereby reversing their diabetes. In addition, researchers found that mice on a high calorie diet given chronic low doses of the compound resveratrol were lived substantially longer because the chemical boosts the activity of sirtuins — proteins that help defend cells against damage and illness associated with old age. Because resveratrol is found in red wine, it might explain why the French are relatively healthy despite their high fat diet. Chronic exposure to low levels of resveratrol “could very well explain the French Paradox,” said Prof Auwerx. |
