Long-term walnut supplementation without dietary advice induces favorable serum lipid changes in free-living individuals

European Journal of Clinical Nutrition volume 65, page 422 (2011)Cite this article

Subjects

After evaluating the 24-h dietary recalls and compliance method, we found that subjects while on the walnut-supplemented diet had a higher total energy consumption than during the control diet. The mean difference between daily total energy intake during the two diet periods (133 kcal) is less than the actual energy intake from walnuts (231 kcal), which suggests partial substitution of other foods in the walnut-supplemented diet. This approximately 100 kcal difference was mainly from carbohydrate food resources that do not have any plasma lipid-lowering effect (Siri-Tarino et al, 2010). Thus, it is very unlikely that the observed effects of walnut consumption on reducing serum lipids in this trial be due to a mixed substitution effect of carbohydrate foods with walnuts or carbohydrate foods alone.
