If you often eat foods rich in estrogen and collagen, your breasts may get bigger, but if you often eat foods high in fat, your breasts will generally not get bigger. In addition, there are no drugs or health supplements that can make your breasts bigger if you eat them regularly. The size of your breasts is closely related to nutritional factors. You can usually eat more estrogen-rich fruits, such as papaya, apple, pomegranate, etc. You should also enrich your diet with more fruits and vegetables to replenish various vitamins and eat more foods that contain more collagen, such as pig’s feet. All these foods can help breast development and make the breasts bigger.
