Walnuts have been shown to reduce serum lipids in hyperlipidemic individuals with a well-controlled feeding trials. Current study have been determined the effects of daily walnut consumption on serum lipids, fasting glucose and insulin levels in hyperlipidemic individuals.
In this, randomized controlled trial, mild to moderate hyperlipidemic subjects were randomly divided into 2 groups as walnut-enriched (n=20) and control (n=17) groups for 6 weeks. All subjects adhered to a medical nutrition therapy as low-fat and low-cholesterol diet. The walnut-enriched group was supplemented with 40 g/day of walnuts added to their diets. In order to follow nutritional status of subjects, they were visited every 15 days (in total 4 times). Anthropometric measurements of the subjects were taken and were monitored at each visit during the study. Blood samples were measured at the beginning and again at the end of the study.
