You will almost certainly have read claims about GM crops with supposed nutritional benefits. Two of the most hyped are Golden Rice and GM tomatoes with supposed anti-cancer properties. These crops have, however, to date not been commercialised, even though in the case of Golden Rice it has been promoted as a life-saver for over a decade.
But while stories about GM "miracles" are lapped up uncritically by the media, non-GM research into solving exactly the same kind of problems seems to get minimal if any reporting, even though it has been far more successful.
Of course, a note of caution needs to be struck about food faddism. The supposed benefits of foods we've been told are healthy in the past have often later been brought into serious question. Even beta carotene, the friendly substance found in yellow and green vegetables, is presented by different authorities as variously a cancer fighter and a cancer promoter.
But for those who are attracted by the idea of "neutraceutical" foods, we don't need GM. Here are some non-GM examples of supposed "superfoods".
