DASH Diet: A Scientific Approach to Lowering Blood Pressure

Scientific research has shown that the DASH diet (Dietary Approaches to Stop Hypertension) can help people lower their levels of hypertension. The DASH diet, known for its efficacy in promoting heart health, was developed and promoted by the National Heart, Lung, and Blood Institute (NHLBI), a division of the National Institutes of Health. 

In this detailed work, we will look at the key principles of the DASH diet, its many forms, recommended foods, and regular dietary goals.

  • Before diving into the specifics of the DASH diet, it’s essential to understand the effects of high blood pressure. 
  • A systolic blood pressure reading of more than 130 mmHg and diastolic arterial pressure of more than 80 mmHg are considered to be hypertension levels. 
  • High blood pressure, sometimes referred to as hypertension, is a serious condition that increases the risk of heart attacks, strokes, and other illnesses.
