...enough to make you reach for a bowl of ice cream. For years researchers have said that maintaining a diet that's high in fiber--found in fruits, vegetables and whole grains--should lower your risk of developing colon cancer. Now comes word that a study of nearly 89,000 women, published in last week's New England Journal of Medicine, has found that fiber makes no difference. A smaller study of men in 1997 arrived at a similar conclusion. This is the sort of neck-snapping nutritional news that drives consumers crazy. First something is good for you; then...
Well, here's my advice: Don't trade your oat bran for fried onion rings just yet. There are lots of other reasons, backed by solid research, to eat plenty of fiber. Study after study shows that fiber lowers blood pressure and cholesterol level, as well as your chances of developing adult-onset diabetes. And even if it turns out that fiber doesn't prevent colon cancer, it does help maintain your intestinal health in other ways. Folks who eat lots of fruit and vegetables don't usually develop diverticulitis, an often painful inflammation of the intestinal wall...
What made anyone think fiber could prevent colon cancer in the first place? It all started 30 years ago, when a British medical missionary named Denis Burkitt suggested that the reason colon cancer is rare in Africa is that Africans consume much more fiber than North Americans and Europeans. Perhaps, later researchers argued, the extra fiber sweeps the bowel clean of potential carcinogens or somehow alters the intestinal chemistry to retard tumor growth. A few small studies supported the link, while others didn...
...MIMID MINIATURE MINE DETECTOR With 70 million land mines buried out there, this sleek, telescopic diviner with its Miesian line couldn't have arrived sooner. Created by Gerhard Heufler, its carbon and glass fiber-reinforced plastic body comes in basic GI Joe green, weighs 3 lbs. and quickly collapses into a small backpack for transporting to remote areas. The controls take just a few minutes to master. This is good design with a good purpose...
Other strategies for reducing the amount of logging include making products using recycled wood and wood substitutes. Kafus Environmental Industries of Boston makes panelboard from reclaimed waste wood and newsprint from kenaf, a tall plant loaded with fiber that can be grown on farms...
