Food therapy, also known as food therapy, is a method of using food to influence various aspects of the body’s functions to achieve health or to heal and prevent disease. Food is generally considered to be an edible substance that provides the body with various nutrients needed for growth, development and healthy survival. In other words, the primary role of food is nutritional. In fact, Chinese medicine has long recognized that food is not only nutritious, but can also cure diseases. In order to help women stay away from the threat of gynecological tumors, experts have put forward several suggestions for women to prevent gynecological tumors: firstly, to establish the concept of prevention, women aged 20-40 should do monthly breast self-examination, many breast cancers are diagnosed by patients who find lumps on their own. Secondly, to participate in tumor screening, effective cervical cytology examination will greatly reduce the mortality rate of cervical cancer, while as ovarian cancer appears early in the pelvis or large abdominal cavity with spread implantation, or lymphatic metastasis, it is not easy to be detected by general physical examination, so it should be combined with some special examinations, such as tumor marker examination, imaging examination, etc. In addition, female friends might as well prevent tumor from the perspective of dietary therapy in daily life. For example, red fruits and vegetables such as red apples and red peppers contain certain natural phytochemicals that can effectively inhibit the growth of some gynecological tumor cells and at the same time reduce their reactivity to estrogen, thus having the effect of preventing gynecological tumors. In addition, onions, purple grapes and other fruits and vegetables also have similar effects. Numerous surveys have found that women who consume sufficient calcium are 54% less likely to develop ovarian cancer than those who consume less calcium. This is because adequate calcium helps control the growth and spread of cancer cells. Therefore, women should pay attention to proper supplementation of high-calcium foods, especially postmenopausal women should have a daily calcium intake of 1000 mg. This requires insisting on drinking milk or eating dairy products every day, and often eating soy products, small shrimp skin, small fish, seaweed and capers. Women of childbearing age consume more whole grains in their diet to keep the appropriate level of estrogen in the blood circulation and avoid high estrogen levels that can lead to breast diseases. Kelp contains a large amount of iodine, which can stimulate the anterior pituitary gland to secrete luteinizing hormone, (Global Mother and Child) to promote ovarian follicular luteinization and balance the estrogen level in the body. Therefore, regular consumption of kelp can help prevent and treat breast enlargement. Studies have shown that red grape skins and seeds contain a natural anti-cancer substance that prevents high estrogen levels from stimulating breast tissue and causing malignant changes. Therefore, women should drink a moderate amount of red wine (1 small glass is enough) or eat some grapes every day. The natural ingredients in these grapes can help women prevent breast cancer and also prevent heart disease. Food, like medicine, has four qualities: cold, hot, warm and cool, and five flavors: sour, bitter, sweet, pungent and salty. Clinical experience tells us that skin cancer ulcers are forbidden to eat meat and fishy hair; lung cancer is forbidden to eat spicy food; edema is forbidden to eat salt; jaundice is forbidden to eat fat; warm fever is forbidden to eat spicy and hot food; cold disease is forbidden to eat melons and fruits; patients under radiotherapy and chemotherapy, who feel fever, sore throat and dry stool, can eat more vegetables, melons and fruits and other cold food, but pay attention to not too much, so as not to affect the patient’s gastrointestinal function; ginger, pepper, garlic, wine, etc. are pungent and hot. If tumor patients have cold pain in stomach and abdomen, they can eat them, but if they eat more, they will produce phlegm and fire, which will stimulate tumor, and patients with chest and abdominal tumor and skin tumor should be cautious; patients with digestive organs such as oral cavity, throat, esophagus, stomach, intestine, liver and pancreas should eat less or do not eat meat, fat and fried food. Certain foods should be avoided when taking certain Chinese medicines, such as turtle nail avoiding amaranth, thornbush avoiding fish and crab, asparagus avoiding carp, atractylodes avoiding peach and garlic, honey avoiding green onion, iron filings avoiding tea, ginseng avoiding vegetable tetras, etc.
