The Spectrum

摘要

It has been almost 18 years since Dr. Dean Ornish’s nbook, Dr. Dean Ornish’s Program for Reversing nHeart Disease, was first published. He followed this nup several years later with Eat More, Weigh Less in 1993. nThis was before the Atkins’ diet craze, and frankly, before ndiet books were the major force in publishing that they nare today. In the intervening years, much has happened. nThe prevalence of obesity has continued to rise and indi-nviduals looking for a “diet book” have many more choic-nes than they did in 1990. Despite these changes, the name n“Dean Ornish” remains synonymous in many people’s nminds with Bay Area executives paying a lot of money nto learn to like a vegetarian diet, yoga, and meditation. nOver the years Dr. Ornish was often pitted against Dr. nAtkins in debates and open forums at national scientific nmeetings with the result that many people simply became nconfused about the role of macronutrient composition in a nweight reducing diet. Then came a number of well-done ncontrolled clinical trials of different diet plans including nthe Atkins diet and the Ornish plan. These studies began nto provide objective information about the effectiveness nof these diets. Now we have a new book by Dr. Ornish: is nthere something new here?
