If there is an increase in low pressure and the diagnosis of diastolic hypertension is made, a diet of low salt, low fat and more cellulose is necessary. Hypertension, including diastolic hypertension, is a very important risk factor for the occurrence and development of atherosclerosis. Hypertension will damage the heart, brain, kidney and other target organs, causing clinical acute cardiovascular and cerebrovascular events. Therefore, it is necessary to control blood pressure as soon as possible and control it in an ideal, stable and stable state. Among them, diet is particularly important for patients with hypertension. The first thing to do is to eat a low salt and low-fat diet. With a low salt diet, the daily intake of salt should not exceed 6 grams. If it exceeds 6 grams for a long time, salt sensitive hypertension will occur. Not only that, but also a low-fat diet, because hypertension is a risk factor for the occurrence and development of atherosclerosis, which can damage endothelial cells. If lipid deposition aggravates the occurrence and development of atherosclerosis. Therefore, it is suggested that patients with hypertension should eat less food containing fat and high fat, more coarse grains and fruits, and more food containing vitamins and cellulose, which is very beneficial to the delay of atherosclerosis in patients with hypertension.
