It has long been suspected that drinking red wine confers some health benefits, but researchers have recently pinpointed a molecule found in red grapes or wine that might be responsible. This BBC report entitled "Wine Allows Guilt-Free Gluttony," describes the role that resveratrol was found to play in the health of mice eating a high fat diet.
To investigate the effects of the molecule on mammals, the researchers looked at middle-aged mice fed on a high-calorie diet, with 60% of the calories coming from fat.So, the article seems to be saying, perhaps we can have our cake and eat it too. As long as we eat it with a big glass of red wine.
These mice shared many of the problems of humans on an equivalent diet, including obesity, insulin resistance and heart disease.
They discovered the mice given resveratrol alongside their food did not lose weight but they showed decreased glucose levels, healthier hearts and liver tissue, and better motor function compared with the mice on the same diet but without the supplement.
