From this article A big fat surprise for dietary dogma comes this quote: “Last month, in an epic climbdown, the U.S. Dietary Guidelines Advice Committee, whose guidelines influence millions of people, finally dropped its recommendation to restrict cholesterol. “Cholesterol is not a nutrient of concern for overconsumption,” it said. And this: "Just about everything we thought we knew about the evils of cholesterol and fats has turned out to be wrong. The doctors, the nutritionists, the dietitians, the heart societies, the experts at Health Canada, the food pyramid that hung on the wall in school – the entire health and medical establishment, in fact, have been perpetuating a big fat fraud." Strong statements. The article goes on to say the previous prevailing wisdom that grains, pasta, starchy vegetables and refined carbohydrates are better than eggs and meat turns out to be wrong. They have actually made us fatter and sicker. Another reversal occurred with butter versus margarine years ago and now researchers are rethinking the dangers of salt. It is amazing how many things we thought to be bad or unimportant turn out to be the opposite. In a similar vein in the field of exercise, the importance strength training to good health and fitness has steadily gained currency, while the importance of aerobic exercise has waned. You might want to do both. At Austin Personal Trainers and New Orleans Personal Training we recommend that clients strength train and also do something they enjoy whether it be running, swimming, or walking the dog. We feel that is prescription for sticking to a program - oh, and a good diet of course.
