Hypertensive patients should follow the doctor’s instructions for lifestyle intervention, there are no special contraindications in diet, non-allergic food can be eaten, but should be reasonable diet. Hypertension is a complex disease triggered by multiple factors, and dietary factors are one of them. And high sodium, low potassium diet is the main risk factor for the development of most hypertensive patients in China. In addition, high protein intake is an antihypertensive factor, and high saturated fatty acid in the diet is also an antihypertensive factor; the amount of alcohol consumption is linearly correlated with the blood pressure level, especially with the systolic blood pressure correlation is stronger. Therefore, although there is no special contraindicated food for hypertensive patients, they should reduce sodium and supplement potassium salt intake, eat fresh vegetables and fruits daily; reduce fat intake, reduce cooking oil intake, eat less or no fatty meat and animal offal, quit smoking and alcohol, and cooperate with other lifestyle management such as exercise. Rational diet is an important part of hypertension treatment. Only with strict dietary control as prescribed by the doctor can blood pressure levels be better controlled and the development of complications slowed down.
