Rode wijn en afvallen.*

Uit onderzoek blijkt dat een bepaald gen, genaamd SIRT1, de aanmaak van nieuwe vetcellen vermindert en de vetverbranding doet verhogen. Nu is gebleken dat de stof Resveratrol, die zich in hoge concentraties in rode wijn bevindt dit gen SIRT1 doet activeren, althans dat is gebleken bij muizen.

- Red wine may help stimulate a gene that can reduce the number and size of fat cells in the body.

Studies on the gene, called SIRT1, have demonstrated that it can reduce the development of new fat cells and increase the "burn rate" of fat within existing fat cells. This gene apparently represses fat-related proteins that tell the body to store fat when food becomes "scarce." When a body senses that its caloric intake has been reduced, it becomes more efficient at storing calories.

Researchers of the study, published in the July issue of Nature, found that a substance called resveratrol, which is concentrated in red wine, appears to speed up the activity of SIRT1 in mice, leading to a higher metabolism rate.

Red wine has been found to have some heart-protective properties. For instance, substances within wine act as antioxidants, which reduce the development of atherosclerosis. They also help raise good cholesterol levels and may lower blood pressure.

However, more research is necessary on the relationship between red wine and its potential health benefits. Experts do not recommend drinking for the sake of cardiovascular benefits. For people who do drink, moderation is the key. Moderate consumption is limited to one drink per day for women and no more than two drinks per day for men (juli 2004)
