Awareness of the importance of good nutrition for good heart health has been on the rise here in Syracuse. The American Heart Association office here at 17 Technology Place PO Box 3049 Syracuse NY 13220-3049 phone: (315) 234-4700, places an emphasis on good nutrition for cardiovascular health.. A news release from the American Heart Association highlights a new dietary consideration for heart health, “Soy/milk protein dietary supplements linked to lower blood pressure.”
This study has shown that soy and milk protein dietary supplements lower systolic blood pressure compared to refined, simple carbohydrate supplements. The researchers suggest that by replacing dietary refined carbohydrates with foods or drinks high in soy or milk protein you might be able to prevent or treat high blood pressure. The journal Circulation: Journal of the American Heart Association has published this study.
Studies prior to this study have shown that a diet rich in low-fat dairy products reduces blood pressure. It has been reported that about 75 million Americans have high blood pressure, which is a “silent killer” that can cause heart attacks, heart failure, strokes, kidney damage and other potentially fatal events.
Dr. Jiang He, one of the researchers for this study, has said “Some previous observational research on eating carbohydrates inconsistently suggested that a high carbohydrate diet might help reduce blood pressure. In contrast, our clinical trial directly compares soy protein with milk protein on blood pressure, and shows they both lower blood pressure better than carbohydrates.”
The participants in this study were age 22 or older, with systolic blood pressure ranging from 120 to 159 mmHg and diastolic blood pressure from 80 to 95 mmHg. Each participant was randomly assigned to take 40 grams of soy protein, milk protein or a refined carbohydrate supplement every day, for eight weeks each. The supplements for this study were made in a way that allowed the researchers to compare what the effects were of soy protein, milk protein, and refined complex carbohydrate on the blood pressure of the participants without changing sodium, potassium, and calcium.
The results of this study showed no decrease in diastolic blood pressure. There was a small decrease in systolic blood pressures associated with soy/milk protein. This was significant because previous research has shown “a 2 mmHg decrease in systolic blood pressure could lead to 6 percent fewer stroke-related deaths, a 4 percent lower rate of heart disease deaths and a 3 percent reduction in overall deaths among Americans”.
