Study Finds That Eating Nuts Helps Lower Cholesterol Levels

May 10, 2010: 09:21 AM EST

A U.S. study that examined data from 25 clinical trials in seven countries has found that eating nuts, which are rich in protein, unsaturated fatty acids, fiber and other nutrients, is associated with improved blood cholesterol levels. The trials involved 583 women and men with both high and normal cholesterol levels. Trial participants who ate an average of 2.4 ounces of nuts a day experienced an average 5.1 percent reduction in cholesterol, a 7.4 percent reduction in so-called “bad” cholesterol and an 8.3 percent change in the ratio of “bad” to “good” cholesterol. In addition, blood triglyceride (fat) levels dropped 10.2 percent among individuals whose triglyceride levels were already high. “Increasing the consumption of nuts as part of an otherwise prudent diet … has the potential to lower coronary heart disease risk,” researchers concluded.
