The Dietary Approach to Stop Hypertension (DASH) diet alone could decrease systolic blood pressure by about 6 to 11 mm Hg as per the study. It is the first-line pharmacologic therapy along with lifestyle modification for hypertension. Know more about the DASH diet.
With modern lifestyle, we are seeing a notable rise in diseases like hypertension, diabetes, obesity, coronary artery diseases, etc. Chronic life-threatening conditions owing to these diseases account for a major percentage of deaths in the country. With advancements in Science and technology and cutting-edge diagnostic techniques, unfortunately, there has been no decline in the case numbers in fact they are getting multifold. Experts and researchers are trying hard to find an integrated approach to manage this growing epidemic. Early diagnosis and medications are still the mainstays of disease management.
Fortunately, the risk factors for these diseases can be controlled by living a healthy and well-balanced lifestyle.
The Dietary Approach to Stop Hypertension (DASH) diet originated in the 1990s. In 1992, the National Institute of Health (NIH) started funding several research projects to see if specific dietary interventions were useful in treating hypertension. No lifestyle modifications were done and only dietary alterations results were noted to avoid confounding factors. Researchers want to see the impact of dietary alterations only. They found that only the dietary intervention alone could decrease systolic blood pressure by about 6 to 11 mm Hg. This effect was seen both in hypertensive as well as normotensive people. Based on these results, the DASH diet became the first-line pharmacologic therapy along with lifestyle modification for hypertension.
