The most important thing is to maintain a normal diet for mastitis. When a woman has mastitis during her monthly period, she should maintain a normal diet, avoiding spicy, greasy or cold foods for a short period of time to prevent irritation of the stomach and intestines or aggravation of the inflammation. During this period, you should eat foods rich in vitamins, high-quality proteins and minerals to replenish your body with nutrients. The actual mastitis patient can also eat some noodles or porridge, which can be easily digested and absorbed by the body. The patient should go to the hospital in time to take the appropriate method to treat the disease, but also to eat a balanced diet.
