The demographic information, including age, gender, marital status, education, physical activity, and body mass index (BMI) are summarized in Table 1. The blood biochemical parameters, BP parameters, and BP medications of the participants at the beginning of the clinical trial are summarized in Table 2. Daily dietary intake in detail was recorded in 4 steps of the clinical trial (Table 3). BP parameters were taken from the left arm of participants using 24-hour ambulatory blood pressure monitoring (ABPM) device at the end of each step. Biochemical tests were carried out in Ghaem Hospital, Mashhad University of Medical Sciences, Iran. Blood samples (5 ml) were taken from the forearm veins of patients in the fasting state (14-hours). The laboratory experiments were performed in both groups pre- and post-treatment: Hematologic tests performed included complete blood count with differentiation (CBC diff), plasma lipids; total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and triglyceride (TG), liver function tests; serum glutamic oxaloacetic transaminase (SGOT or AST), serum glutamic pyruvic transaminase (SGPT or ALT) and alkaline phosphatase (ALP), blood urea nitrogen (BUN) and serum creatinine (SCr), electrolytes; sodium (Na), potassium (K), calcium (Ca) and phosphorus (P).
