"The practical significance of the study is that eating an easy-to-incorporate amount of walnuts and fatty fish can cause meaningful decreases in blood cholesterol and triglycerides even in healthy individuals," says lead author Sujatha Rajaram, Ph.D., associate professor in the department of nutrition at
Following the qualified health claim issued by the Food and Drug Administration, researchers found that incorporating approximately 1.5 ounces of walnuts (42 grams, a handful of whole nuts or about three tablespoons of chopped nuts) into the daily diet lowered serum total cholesterol by 5.4 percent and LDL (bad) cholesterol by 9.3 percent compared to a control diet based on USDA recommendations.
Using American Heart Association guidelines, the researchers also found that a diet including two servings of fatty fish per week (roughly four ounces each as recommended by the AHA for individuals without heart disease) decreased triglyceride levels by 11.4 percent. Additionally, it increased HDL (good) cholesterol by 4 percent, but also slightly increased LDL (bad) cholesterol compared to the control diet. The fish used in this study was salmon.
