Quite a number of fruits and vegetables have been found to have very strong anti-oxidant properties. There are various standard experiments that you can do in the laboratory to measure, to quantify how strong an antioxidant a particular compound is, or a particular extract that may have many, many compounds in it. And, it's been found very conclusively that especially blueberries have a very, very high antioxidant capacity. And, this may be a good thing for extending one's life a little bit. But, unfortunately, it's one of these cases where most people have a pretty good antioxidant balance already, even if they're eating more of a variety of things, maybe not even blueberries at all. And, the addition of extra anti-oxidant capacity on top of that may do very little good. In fact, for some people, we think that it might even do a little bit of harm.
