Nutrient intake has been related to the development of high BP, and nutritional modifications have become an important approach for the treatment and prevention of high BP. While the effect of sodium, potassium, and alcohol on BP has been studied extensively, the effect of dietary macronutrients, such as protein, has not been as well studied. Results from this study may provide justification for recommending protein supplements for the prevention and treatment of high BP in the general population.\n\nDESIGN NARRATIVE:\n\nThe study will enroll 280 healthy participants with BP levels higher than optimal or with stage-1 hypertension (systolic BP of 120-159 mm Hg and diastolic BP of 80-95 mm HG). Participants will be recruited by a mass mailing and a worksite/community-based BP screening in New Orleans, Louisiana, and Jackson, Mississippi. Following a two-week screening period, eligible participants will receive either 40 grams of soy protein, 40 grams of milk protein, or 40 grams of complex carbohydrates (control) daily for eight weeks. Following those eight weeks, participants will not receive any supplements for three weeks. Participants will then repeat the process with the other two supplements. The primary outcome will be difference in BP during the soy protein supplementation, milk protein supplementation, and placebo control phases. In addition, changes in serum lipids; waist and hip circumference; and fasting plasma insulin, glucose, leptin, and homocysteine will be monitored and examined in terms of impact on BP level.'},
