Consistent blood pressure measurements of 140/90 or higher are an indication of high blood pressure, or hypertension, which usually requires medication. However, the findings of nutritional scientists about our diet's effect on lowering blood pressure are very important in combination with prescribed medication and exercise.
Why Nutritional Science Matters
Nutritional scientists cover a variety of fields, including the distribution and marketing of foods, and studying the effects that different food have on us. They also help people learn to make good food choices for their health, for example, for lowering blood pressure.
Food's Effects on Hypertension
Nutrition science tells us that obesity is a risk factor for developing hypertension, so what and how much we eat affects our ability to maintain a healthy blood pressure. In fact, some foods raise blood pressure when consumed in greater than moderate amounts, such as high sodium foods and alcohol.
Dietary Guidelines for Americans
The Dietary Guidelines for Americans is updated every five years by the Department of Health and Human Services and the Department of Agriculture. It "provides science-based advice to promote health and to reduce risk for major chronic diseases through diet and physical activity." This key scientific document is a prime resource for nutritional advice as it affects health.
What is the DASH Diet
DASH (Dietary Approaches to Stop Hypertension), was developed specifically to lower high blood pressure, and is based upon the Dietary Guidelines. DASH uses the findings of nutritional science to recommend a strong, effective heart-healthy diet supported by the National Institutes of Health.
How Does DASH Lower Blood Pressure
DASH recommends a diet low in sodium, high in potassium, with fresh fruits, vegetables, and low-fat dairy products. According to the DASH brief, "Research shows that high blood pressure can be prevented---and lowered---by following the Dietary Approaches to Stop Hypertension (DASH) eating plan."
