Keeping your blood pressure and weight in check may reduce your risk for a host of potential health problems down the road — from diabetes to heart disease. If your blood pressure is too high, changing your diet and losing a little weight just might be the ticket to lowering it.
High blood pressure, or hypertension, is when the force of blood against the walls of your arteries gets too high and damages your body. High blood pressure can lead to heart disease, heart failure, stroke, kidney failure, and other serious health problems.
It is normal for blood pressure levels to go up and down. But if your blood pressure stays above the normal range most of the time, you may have prehypertension or high blood pressure.
Normal: 120/80 millimeters of mercury (mmHg)
Prehypertension: 120-139/80-89 mmHg
High blood pressure: 140/90 mmHg and above
High blood pressure with diabetes or chronic kidney disease: 130/80 mmHg
You are less likely to develop prehypertension and high blood pressure if you maintain a healthy weight. A host of other healthy lifestyle habits can also reduce your risk:
If you carry too much weight, talk to your doctor about ways to lose some of it. Even a modest amount of weight loss may have an effect on your blood pressure.
Dietary Approaches to Stop Hypertension (DASH) is a study by the National Institutes of Health on the effect that different food choices have on high blood pressure. The DASH diet is the result of this study — a diet that can significantly lower blood pressure even after just a couple of weeks.
The DASH diet is rich in fruits, vegetables, whole grains, fish, poultry, beans, seeds, nuts, and low-fat dairy. These foods are high in nutrients such as potassium, magnesium, calcium, fiber, and protein. The DASH diet is low in sodium, sugar, desserts, sweetened drinks, fats, and red and processed meats.
The DASH diet requires no special foods or recipes. To follow the DASH diet you simply have to have a certain number of daily servings from various food groups. The number of servings depends on the number of calories you eat, your age, and your activity level.
