1, control the total calories, especially for obese or overweight people, and limit their total calorie intake to less than their consumption.

2. Limit the intake of sodium and increase the supplement of potassium. Foods with low sodium and high potassium are beneficial to lowering blood pressure, and potassium can prevent blood pressure from rising due to excessive salt. Foods rich in potassium include Gracilaria lemaneiformis, pea seedlings, celery, loofah, eggplant, potatoes and miscellaneous beans.

3. Supplement calcium and magnesium. Calcium is related to the contraction and relaxation of blood vessels. Eating foods rich in calcium can reduce the risk of hypertension, such as fish, poultry, meat, eggs, milk and so on. Increasing magnesium intake can dilate peripheral blood vessels and lower blood pressure, such as mushrooms, spinach, bean products and longan.

4. Increasing the intake of dietary fiber and accelerating the excretion of cholesterol are also very beneficial to the prevention and treatment of hypertension, such as coarse grains and vegetables.

5. Limit the intake of lipids and provide 40-50g of fat every day. In addition to coconut oil, soybean oil, vegetable oil, peanut oil, sesame oil, corn oil and other vegetable oils all contain vitamin E and linoleic acid, which has a certain effect on preventing blood vessel rupture in patients with hypertension.

6. Other foods with antihypertensive effects include onions, garlic, carrots and chrysanthemums. The diet of patients with hypertension should also be individualized according to their own situation.
