...carb craze hits the soda aisles this month with the arrival of Pepsi Edge and Coca-Cola C2. Both drinks boast about half the carbs, sugar and calories of regular colas while promising a fuller flavor than diet sodas. The balancing act is achieved with a mixture of corn syrup and artificial sweeteners. But how do they stack up to the originals? Both low-carb versions taste surprisingly close to their full-sugar progenitors, but in a head-to-head tasting, C2 seems a little less artificial and has less of an aftertaste than Edge...
...hardly news anymore that Americans are just too fat. If the endless parade of articles, TV specials and fad diet books weren't proof enough or you missed the ominous warnings from the National Institutes of Health, the Centers for Disease Control and Prevention and the American Heart Association, a quick look around the mall, the beach or the crowd at any baseball game will leave no room for doubt: our individual weight problems have become a national crisis...
...high blood pressure, stroke, diabetes, infertility, gall-bladder disease, osteoarthritis and many forms of cancer. The total medical tab for illnesses related to obesity is $117 billion a year--and climbing--according to the Surgeon General, and the Journal of the American Medical Association reported in March that poor diet and physical inactivity could soon overtake tobacco as the leading cause of preventable death in the U.S. And again, Americans recognize the problem. In the TIME/ABC poll they rated obesity alongside heart disease, cancer, AIDS and drug abuse as among the nation's most pressing public health problems...
...love affair with sugar--and also with salt, another crucial but not always available part of the diet--goes back millions of years. But humanity's appetite for animal fat and protein is probably more recent. It was some 2.5 million years ago that our hominid ancestors developed a taste for meat. The fossil record shows that the human brain became markedly bigger and more complex about the same time. And indeed, according to Katherine Milton, an anthropologist at the University of California, Berkeley, "the incorporation of animal matter into the diet played an absolutely essential role in human evolution...
...spears and clubs was a marathon undertaking--and then you had to hack up the catch and lug it miles back to camp. Climbing trees to find nuts and fruit was hard work too. In essence, early humans ate what amounted to the best of the high-protein Atkins diet and the low-fat Ornish diet, and worked out almost nonstop. To get a sense of their endurance, cardiovascular fitness, musculature and body fat, say evolutionary anthropologists, look at a modern marathon runner...
