effects of walnut consumption on lipid profile of female undergraduate students

Introduction: cardiovascular diseases (cvds) are considered to be the leading cause of mortality across the world, representing a major health concern. factors associated with lifestyle (e.g., nutrition) have an undeniable effect on the prevention and treatment of cvd. walnut has a unique profile and is rich in polyunsaturated fatty acids, which may improve blood lipids and cvd risk factors. the present study aimed to assess the effects of walnut consumption of the lipid profile of female undergraduate students. methods: this randomized clinical trial was conducted on 50 participants with normal lipid profile, who were randomly divided into two groups of intervention and control. the applied regimen involved the addition of 40 grams of peeled walnuts per day to the routine diet of the intervention group for four weeks. results: the results of paired t-test indicated that the calorie, protein, and fat intake increased significantly in the intervention group after the consumption of walnuts. at baseline, the body mass index in the control and intervention groups was 21.66±4.06 and 21.22±4.03 kg/m2, respectively, which showed no significant difference before and after the intervention. however, a significant reduction was observed in the serum levels of low-density lipoprotein (ldl) and triglyceride (tg) in the intervention group after the consumption of walnuts. conclusion: according to the results, the consumption of walnuts could effectively decrease serum ldl and tg.
