Clinical Trial Summary

Flaxseed and olive oil consumption have beneficial effects on cardiovascular risk factors. Nonetheless the effects of their simultaneous consumption have not yet been studied.The purpose of this study is to investigate the effects of a healthy diet containing flaxseed and olive oil compared with healthy dietary advice on cardiovascular disease risk markers in patients with coronary artery disease (CAD), in improving flow-mediated dilation, plasma lipid profile and fatty acids composition of red blood cells.


Clinical Trial Description

A randomized controlled clinical trial will be conducted in Rajaie Cardiovascular Center 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 50 eligible coronary artery disease patients, aged 30-75 years. Intervention group will be received a heart-healthy diet with a specified number of food servings from different food groups (including vegetables, fruits, grains, dairy products, meats) + daily consumption of 30 grams of flaxseed + 25 mL/day of refined olive oil (equivalent to 4 tablespoons; 2 tablespoons for lunch and 2 tablespoons for dinner); and control group will be received recommendations for a heart-healthy diet, such as those of the American Heart Association for 3 months. These include eating at least 5 servings of vegetables and fruits daily, reduction in the consumption of sources of saturated and trans fats by avoiding the consumption of high-fat red meats and replacing them with low-fat meat or with poultry and fish, replacing low-fat dairy sources with regular or high-fat ones; consumption of regular vegetable oils such as canola and sunflower; reduction in salt consumption; and reduction in the consumption of simple sugars, for 3 months. Flow mediated dilatation (FMD) in brachial artery via ultrasonography, plasma levels of lipids and lipoproteins via enzymatic method, and fatty acids composition of red blood cells via gas chromatography method were measured. ;
