Blood pressure is too low to be treated by ingesting food, which has only nutritional value for the body. Blood pressure is the pressure per unit area of blood vessel wall when the body’s blood pressure flows in the blood vessels, including diastolic pressure, systolic pressure and pulse pressure. Clinical factors that cause low blood pressure include acute myocardial infarction, severe trauma, infection, allergy and hemorrhage. Food itself can only provide the body with the required nutrients, such as fresh fruits and vegetables such as celery, carrots, lychee, etc. can provide the body with rich vitamins and so on.
