High blood pressure is prohibited mainly high salt and high fat food, so patients with high blood pressure should have a low salt and low fat diet in the usual diet structure, control the intake of salt and oil, and consume less salty food, sauce and other high salt food. Control the intake of animal oil and vegetable oil, including fatty meat. It is also important to control the intake of cholesterol, such as animal offal, as well as egg yolk. This is because high salt and high fat can aggravate atherosclerosis and aggravate hypertension. In addition, from the perspective of Chinese medicine, hypertension is more common in the form of hyperactive liver yang and liver fire, which can manifest as dizziness, irritability, irritability, bitter mouth and dry throat. In addition to a low-salt, low-fat diet, patients should also control the intake of spicy foods because spicy foods can fuel fire, which can aggravate hypertension by making the liver fire more intense.
