Patients with coronary heart disease need to maintain a reasonable daily diet, paying attention to low salt, low cholesterol, and low-fat food. The total daily intake of salt should be controlled to under 6 grams. It is best to consume a certain amount of vegetables daily, such as appropriately eating some tomatoes, eggplants, lettuce, broccoli, etc., which are relatively good vegetables. Fruit should also be consumed daily, such as eating some fruit before meals, like kiwi, apples, and pears, which are fruits relatively rich in potassium and magnesium. These elements help further lower blood pressure and prevent the occurrence of arteriosclerosis. In addition, it is also recommended that patients choose some vegetable oils when cooking and use less fat to better prevent the occurrence of arteriosclerosis.
