Protocol summary

Summary
The aim of this study is to investigate the effect of Cashew Consumption on lipid profile, Apo B, Apo A-I, hs-CRP, and Paraoxonase-1 in type 2 diabetic patients. In this parallel group, randomized controlled trial, 50 men and women with type 2 diabetes aged 35-70 years old will be recruited from Iranian Diabetes Society. The study will be explained to each participant to sign informed consent. Prior to the study, the subjects will be required to complete 3-days 24-hour dietary recall. Diets will be analyzed for calorie and macronutrients content. Then, we will substitute 10% of usual daily calorie intake with Cashew in intervention group. The control group will follow their habitual diet. Blood samples will be obtained after an overnight fasting before and after the study. All anthropometric and physical activity variables will be measured both before and after the trial. Diets and medications dosage will be held constant throughout the study and each subject’s exercise level will be kept constant and monitored by physical activity questionnaires (IPAQ).Compliance will be assessed from 3-days 24-recalls which obtain at first, in the middle and at the end of the study.
