A new study by the Karolinska Institute in Stockholm, Sweden, concludes that drinking two or more cups of tea per day may reduce the risk of ovarian cancer. The researchers caution that more study is needed, and that tea drinkers as a group may make healthier lifestyle choices, which may account for the results.
I’ve also written recently on my science-and-technology blog about a study indicating caffeine may alleviate some forms of liver damage. This is all interesting from a scientific point of view, but we shouldn’t take this as license to over-indulge. We’ve all heard stories over the years about favorite “guilt” foods–red wine, chocolate, etc.–with beneficial effects. Many of them can also cause well-known, more harmful effects. As always, discuss matters with your doctor or other medical professional before making any major changes in your diet. Too much of a good thing can be too much, even if it’s nice to know there may be some ancillary benefits.
