DASH (Dietary Approaches to Stop Hypertension) diet is the new trend gaining popularity for its very benefits, hypertension being the first. It is a mixture of old beliefs and modern advancements, as the scientists have extracted the diet from ancient dietary principles. The diet has been studied many times and is proven to be the best for curing hypertension.
World health organization states that hypertension or high blood pressure is the most common disease affecting about 1billion people worldwide. Hypertension is a chronic disorder leading to diseases such as stroke, heart diseases, congestive heart failure, blindness and kidney diseases.
Hypertension is becoming a significant cause of death with a death rate of 1 in every 8 people. There has been a rise in the number of patients suffering from diseases such as hypertension, obesity, coronary artery diseases and diabetes observed by clinicians of the United States in the last 50 years. The drastic increase in the number of people suffering from hypertension has become a cause of concern for the doctors.
DASH is a diet program developed by the News and world report, U.S. and has been proven as the best diet plan to deal with hypertension for the eight consecutive year in a research comparing the DASH diet with about 40 other diets.
According to the researches, DASH when combined with a low-sodium diet works better than any anti-hypertension medicine for lowering the blood pressure.
History of DASH diet
The research for diet affective for lowering the blood pressure was initiated in the 1990s.it was in 1992 when the National Institute for Health began to spend funding to find out if specific changes the diet could help control hypertension.
The trials were put on individuals who were asked to follow the diet strictly and do not make any changes in their lifestyle for reducing the elements of confusion from the study. The systolic blood pressure was found to be decreased by about 6 to 11 mm Hg just by applying dietary intrusions.
The DASH diet was introduced for the first time in 1996. It was proposed in the American heart association meeting and published one year later by the New England Journal of Medicine. The diet was based on 456 people and the aim was to try different diets to check how they affect the dietary patterns for lowering blood pressure of the individual.
Three diets were put into trial which included:
- A standard American diet (control diet)
- Fruits and vegetables diet (similar to control diet but consisting more fruits and vegetables, and lesser snacks and sweets)
- A combination diet (more quantity of fruits, vegetable, nuts low-fat dairy with reduced amount of fats and cholesterol)
Usually the American diets consists of high saturated fats, glycemic load carbohydrates,omega-6 fatty acids and artificial additives, and are proven to be of no use in treating diseases such as hypertension. On the other hand the diet rich in fruits and vegetable and the combination diets are nutritious and consists potassium, calcium, fiber, magnesium and protein, these nutrition are linked with lower blood pressure.
While all the diets provide 3000 mg of sodium (more than the amount suggested by dietary guidelines for Americans) none of them showed any change in weights of the individuals. The combination diet showed the most effect in lowering blood pressure, while the suffering from hypertension saw a much decrease the blood pressure those individuals who were trying the diet but didn’t have hypertension had a maintained blood pressure.
The conclusions of this study were proved to be of major importance for the Dietary Guidelines for Americans in 2010 and for further editions.
