Is the DASH diet healthy?
Read the advantages of DASH diet to stop hypertension below and decide whether this diet is healthy, effective or not. Not only blood pressure control but there so many other wonderful benefits of this diet in terms of general health and wellness.
1. Lowers blood pressure
The first and most important benefit of following the DASH diet is lowering the blood pressure. There are two numbers of blood pressure-
- Systolic blood pressure- blood pressure reading that comes when blood passes through the vessels when your heart beats.
- Diastolic blood pressure- The blood pressure when heart is at rest.
The normal reading would be- 120mmHg systolic and 80mmHg diastolic. High blood pressure is considered when systolic reading is above 140mmHg and diastolic reading is 90mmHg.
DASH diet helps in lowering blood pressure in both healthy and hypertensive people. Interestingly, it was found that even if people didn’t limit their salt intake, their blood pressure lowered. And when they reduced salt intake, BP fell further. Those with the lowest salt consumption saw the most growth in terms of reduced blood pressure. This shows that this diet can effectively bring down blood pressure count. Also, restricting salt intake can aid in lowering blood pressure.
2. May also help you lose weight
Before proceeding, we would like to give a little disclaimer. Talking about weight loss benefits, we aren’t promoting this diet as a weight loss diet. Kindly do not compare this with other diets as DASH diet is particularly designed for high blood pressure.
Weight gain and hypertension is a dangerous combination. If you have fluctuating blood pressure problems, you need to control your weight. The higher the weight, the higher your blood pressure would be. Thus, weight loss is linked to lowering blood pressure. In a nutshell, DASH diet not only helps in controlling hypertension but also brings down weight significantly. This diet restricts calories as you are supposed to cut down sugar and fat from the diet. Thus, all you need to do is follow a calorie-deficit diet like this one.
3. May reduce the risk of cancer
While there is no scientific evidence to prove this but some studies suggest that those who followed DASH diet were less likely to get breast and colorectal cancer.
4. Reduces risk of diabetes
As we mentioned in the beginning, hypertension increases the risk of diabetes. Following DASH diet for hypertension thus also reduces the risk of getting type-2 diabetic by improving insulin resistance in the body. Cutting down sugar intake would automatically cut down diabetes risk.
Is DASH Diet Effective for everyone?
