New York: While the low-fat diet craze led some doctors to worry that Americans would instead start eating too many carbohydrates, a new study suggests that eating low-fat doesn`t have to increase carbohydrate-fueled health risks.Instead, if extra carbohydrates are part of a diet plan that includes more fruits, vegetables, and whole grains, the risk of diabetes - the biggest related health concern -- could actually drop, at least in older women, according to the findings.However, a low-fat, high-carbohydrate diet could create problems in people who already have diabetes, researchers caution."Generally when people reduce the fat in the diet they replace it with carbohydrates," study author Dr. James Shikany told Reuters Health. "There was some concern that the increased carbohydrate intake might lead to if not increased diabetes itself...changes that over time could lead to diabetes.""We had been telling women to decrease their fat intake for a long time and we really didn`t know the possible effects this would have" on diabetes, added Shikany, from the University of Alabama at Birmingham.The results suggest that balancing both diabetes and other disease risks requires considering the kinds of carbohydrates, fats, and proteins we eat, researchers said, rather than just cutting back on one food group and eating more of another.The study, published in the American Journal of Clinical Nutrition, included a group of about 2,300 postmenopausal women who were part of the Women`s Health Initiative trial, which looked at the effect of diet and hormone therapy on disease risks.
Carbohydrates are "obviously not a poison," said Dr. David Jenkins, head of the Clinical Nutrition and Risk Factor Modification Center at St. Michael`s Hospital in Toronto. "If eaten wisely (they`re) useful."However, in general, "we went from a diet that was rich in saturated fat and cholesterol and was also not good (to) a diet which was equally tasty, but relying on refining the carbohydrates in a particular way" that ups the risk of obesity and diabetes, Jenkins, who was not involved in the new research, told Reuters Health. Refined carbohydrates include white bread and rice and sugary drinks and snacks. Jenkins said that getting more fat and protein from vegetable sources, such as by eating beans or adding hummus or peanut butter to bread, is a good way to stave off both diabetes and heart disease. Doctors now generally recommend a diet that has plenty of healthy, non-saturated fats, rather than one that tries to cut back on all fats, Shikany said - but that doesn`t mean the new data isn`t useful. "Things have kind of changed, but there still are plenty of (doctors) who recommend low-fat diets and people who are on these diets," he said. "I certainly think it`s a very safe diet, but the question is, is this the best diet?" Mary Gannon, of the University of Minnesota, said that a diet lower in carbohydrates and higher in fat and protein may actually help people feel fuller sooner - which could lead to weight loss over time. In male patients with diabetes she has studied, men had the most improvement in diabetes markers when they got the smallest percent of their calories from carbohydrates. Shikany added that because the research was limited to women age 50 and up, his findings don`t necessarily apply to men or younger women on a low-fat diet.Bureau Report
