The purpose of this study is to compare the antioxidant activity and changes in the lipid profile of hypertensive individuals taking 30 grams of either flaxseed or sesame powder daily. This is a randomized, single centered, and single blinded study. Researchers and analyzers are not aware of the type of bread that is eaten by patients. Eligible patients will be selected from the patients attending the Yazd Cardiovascular Research Center. Main inclusion criteria are ages between 30 to 65 years, having stage I hypertension, and cholesterol level below 240 mg/dL. Patients using drugs for hyperlipidemia, pregnant patients, or individuals suffering from severe systemic or intestinal diseases, diabetes, or myocardial infarction will be excluded. Total sample size is 90 with at least 45 patients in each group. Patients will be allocated to two groups using blocked randomization block sizes of four. Groups A and B will receive 90 grams of bread containing 30 grams of either flaxseed or sesame powder for 14 weeks, respectively. Measured outcomes include, free radical scavenging capacity, malondialdehyde (MDA), cholesterol, triglyceride, LDL, and HDL. These parameters will be measured at the beginning, middle and end of the study. Questions about eating habits and physical activities will also be asked at these times. After initial blood taking, patients will be instructed to get their weekly breads from a particular store. To be sure patients consumed their breads properly; they will be regularly contacted either face to face or by phone.
