For mastitis, it is primarily important to avoid spicy and stimulating foods, seafood, and lactation-promoting foods. Foods high in fat and sugar, spicy fried foods, and stimulant drinks like liquor and coffee should be avoided. If blood sugar levels are high, certain fruits high in sugar content should also be avoided. For those without diabetes, the issue is simpler; for example, consuming more tomatoes, especially cooked tomatoes, is advisable. The principle is to eat light and nutritious foods. Therefore, tomatoes, green vegetables, loofah, cucumbers, crown daisy, lotus root, and mung bean soup are good options. This also includes oranges, strawberries, apples, grapes, and kiwifruits which are suitable choices.
