Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Accumulating evidence from prospective observational studies and a large clinical trial suggests that nut intake lowers the risk of cardiovascular disease (CVD). Tree nuts are rich in unsaturated fats, soluble fiber, antioxidants, and phytosterols. The purpose of this study is to compare the effects of low calorie diets with a mixture of nuts in comparison with low calorie diets in improving inflammatory markers in patients with stable coronary artery disease.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A randomized placebo controlled clinical trial will be conducted in modares hospital in Tehran, Iran. After review of the inclusion and exclusion criteria and explanation of the design of the study, written consent form will be completed. The participants are 66 eligible patients, aged 35-70 years. Intervention group will be received low calories diets as well as 20 percent of daily calories from mixed nuts (peanuts, pistachio and almond) and control group will be received low calories diets for 8 weeks. Fasting blood sample will be taken to measure inflammatory markers (Interleukine-6 \[IL-6\] and Interleukine-10 \[IL-10\] and C-Reactive Protein \[CRP\]).
