Low-Carb Dieting Takes Another Blow
People who consume more whole grains live longer, according to a new study from Harvard. Researchers analyzed the diets and mortality of more than 118,000 men and women from both the Nurses’ Health Study and the Health Professionals Follow-Up Study and found that, after an average of 25 years follow-up, more whole-grain intake was associated with lower death rates and that every whole-grain serving was associated with a 5 percent lower risk for death in general and a 9 percent lower risk for death from heart disease. Whole grains, for this study, were defined as the whole grain (whole wheat, oats, brown rice, etc.) as well as its pulverized flour form (whole-wheat flour, oat flour, brown rice flour, etc.), which may be found in products such as breads and cereals. The benefits were independent of other lifestyle factors, including exercise and other dietary choices.
These findings support other studies that show avoiding healthful carbs and consuming more animal products increases the risk for dying.
