...Eastern Baltic, for instance, foragers traded seal fat, amber, slate and flint for the farmers' pottery and grain. In coastal regions where oysters or other shellfish were plentiful, foragers felt no particular compulsion to take up the tasks of horticulture. Where farming did spread, he says, it was often through a process of gradual adoption by hunter-gatherers rather than continual migration of farmers. "Gene flow just doesn't correspond to the cultural patterns," he says...
...perhaps American food has become Japanese. Undoubtedly the greatest effect Japanese food has had on American cuisine is to ease its reliance on fat as a taste booster. So it's ironic that the Japanese influence came to the U.S. by way of France, home of butter and foie gras. It all began around the '60s, when Japanese students at the great French cooking schools divulged their own trade secrets. Soon Parisian chefs had adopted such Japanese techniques as arranging food artfully in tiny portions. "The minimalism and simplicity, the sophistication of presentation appealed to chefs in three-star restaurants...
...controlled studies that have been done offer cause for hope. A 1990 study of patients who had coronary heart disease indicated that a regimen of aerobic exercise and stress reduction, including yoga, combined with a low-fat vegetarian diet, stabilized and in some cases reversed arterial blockage. The author Dr. Dean Ornish is in the midst of a study involving men with prostate cancer. Can diet, yoga and meditation affect the progress of this disease? So far, Ornish will say only that the data are encouraging...
...most cited study around--Ornish's in 1990--tested 94 patients with angiographically documented coronary heart disease, of whom 53 were prescribed yoga, group support and a vegetarian diet extremely low in fat--only 10% of total daily calories (most Americans consume 35% in fat; the American Heart Association recommends 30%). Cholesterol changes among the experimental group were about the same as if they had taken cholesterol-lowering drugs. After a year in the program, patients in this group showed "significant overall regression of coronary atherosclerosis as measured by quantitative coronary arteriography." Those in the control group "showed significant overall...
...Fat cells, by contrast, are plentiful and easy to harvest--just ask anyone who has had liposuction. They are also rich in stem cells--not so surprising, in retrospect, since bone marrow and fat develop from the same embryonic tissue. Not only did the researchers get stem cells from liposuctioned human fat, they also made them grow into bone, muscle and cartilage cells--a sign that more ambitious tissue engineering is not out of the question...
