According to the Daily Mail, “A glass of red wine a day could keep polycystic ovaries at bay”, which is one of those stories you’d just love to be true. So often it seems that anyone trying to conceive is told to avoid many of life’s small pleasures – like coffee and wine – so a story suggesting that a glass of red wine every day is actually a good thing for some fertility patients sounds delightful.
The story claims that a natural compound called resveratrol which is found in the skin of grapes could potentially re-balance the hormone imbalances that women with PCOS experience. The women in the trial were given resveratrol in a pill form for three months and it was found to reduce testosterone levels and fasting insulin levels. The scientists leading the trial, which was published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism, suggest it might help reduce the risk of metabolic problems common in women with PCOS. You can find the full report here.
But it reminded me of something – a story some years back about red wine which claimed that drinking lots of red wine would make you lose weight which was duly taken to pieces by the excellent NHS Choices. They made it clear that the amount of the magical resveratrol found in wine is “a fraction of that present in grapes and berries, as much of the chemical is filtered out during the wine production process. You would gain more resveratrol from eating the grapes and berries themselves than drinking wine – but that makes a much less exciting headline.”
And of course, the women in this PCOS study weren’t given wine to drink – they were taking a daily supplement of 1500 mg of resveratrol. Apparently, to get just 500 mg of resveratrol daily by drinking wine, you’d need to be consuming 40 litres, which means to get the benefit from it these women had you’d be getting through 120 litres of red wine a day. Which I don’t think anyone is going to recommend…
