Antioxidant Use Still Small Mixed Bag

Are you gobbling up antioxidants as part of your diet and nutrition regimentregimen? The benefits seems maybemay be, well.

It seems surprising, but even after several decades , we don’t have a clear answer. There is , there’s not, if there is were really cross the wall across-the-board powerful benefits we would’ve would have seen it. , and that’s not the situation.

Walter Willett, . He chairs the Department of Nutrition at the Harvard T. H. Chan School of Public Health. He spoke at a January 15th forum on Cancer and Diet , that wound up touching on diet and health in general.

The studies are, so far, randomized trials that have been done, don’t show much benefit. There was actually a surprising . increase in lung cancer with beta-carotene, one of the antioxidants, in people who smoke or smoked and were heavy drinkersalthough, although there is was no increase in risk in people if you who were generally pretty healthy . to start with. So even the randomized trials give different answers. , I think, that antioxidants are not a magic solution to cancer or other diseases. , but they are there probably are some benefits. One example is , that in the a physicians health study , randomized trial over 12 yearsare, at the end of that period of time , those taking beta-carotene had better cognitive function than people on placebo - a really interesting and potential potentially important finding.

So antioxidants may provide some benefits to some people.

But even if there are, that’s only a small part of the changes . that we need to make them in diet and lifestyle to reduce our risk of cancer. cancers, there is are so many other things that are really quite well documented.

The entire hour-long forum featured featuring Willett and other researchers discussing diet and health is archived on lineonline. Just google “ Harvard public health forum” .
