To tackle Hypertension - Keep a check on Diet
As published in Indian Express on April 14, 2013 - The secret of Good Health is intelligent consumption of beneficial foods rather than simply avoiding harmful foods. With increasing prevalence of hypertension at a young age, strategies for prevention and management need to be understood and implemented. The most well-kown approach for controlling high blood pressure has been reducing intake of sodium. While sodium restriction is important, management of high blood pressure involved many other nutrients and adequate intake of potassium, calcium, fibre, phytochemicals, omega 3 fats and controlling waist size.
The DASH diet, a diet for controlling high blood pressure, evolved out of multi-center studies conducted by National Heart, Lung and Blood Institute, USA. The DASH diet, an eating plan low in fat, saturated fat, and cholesterol and rich in fruits, vegetables, low-fat dairy products along with sodium restriction was more effective in lowering blood pressure than low sodium diets.
A large clinical study tested the effect of DASH diet on patients with elevated blood pressure. Participants ate a diet rich in fruits, vegetables, and low fat dairy products. They avoided red meat, sweeta and sugar rich drinks. The DASH diet provided high amounts of fibre, potassium and magnesium.
In a second study, participants reduced consumption of sodium and salt. Some participants followed the DASH diet, whike others followed a typical American Diet. Results showed that lowered sodium intake led to reduced blood pressure levels in both the groups but the group that followed DASH diet had the most sigificant results.
Heart disease covers a range of disorders which affect our arteries, blood vessels, or the heart, leading to narrowed or blocked arteries and preventing the heart from pumping blood efficiently, thereby leading to hypertension. Hypertension is high persistent blood pressure (above 140 mm Hg systolic and 90 mm Hg diastolic).
