The most important thing for hypertension is diet control, such as low sodium salt and high potassium salt, using less vegetable oil instead of lard, eating less animal viscera, quitting smoking and drinking, avoiding greasy food, and eating more soft-shelled turtle, hawthorn, onion, bitter gourd, garlic and other foods that help to control blood pressure. If conditions permit, the effect of drinking related fruit and vegetable juices will be more obvious, such as onion juice, bitter gourd juice, garlic juice and so on.
