Women should not eat vegetables like this in summer

　　Many people especially like to eat raw cold vegetables or eat them raw in summer. Eating raw vegetables can not only avoid the pain of sweating when eating hot food in hot weather, but also retain the nutrition of the food to the greatest extent. However, not all vegetables are suitable for eating raw. Next, let me introduce to you four types of vegetables that are not suitable for eating raw in summer.

　　1. Vegetables with high oxalic acid content

　　Spinach, water spinach, bamboo shoots, wild rice and other vegetables that contain a lot of oxalic acid are best blanched to remove most of the oxalic acid before being served cold. Because oxalic acid combines with calcium in the intestines to form calcium oxalate, which is difficult to absorb, interfering with the body's absorption of calcium.

　　2. Vegetables rich in fat-soluble nutrients

　　tomato Lycopene in carrots and beta-carotene, which are rich in carrots, are fat-soluble nutrients. They are more easily absorbed by the body after cooking with oil and exert their health care effects. Research has found that tomatoes are rich in antioxidants, lycopene, which can effectively prevent arteriosclerosis and reduce the risk of heart disease. Compared with raw tomatoes, the lycopene in ripe tomatoes is more easily absorbed by the body. According to nutrition experts, carrots are rich in beta-carotene, which can protect eyesight and moisturize skin , improve immunity, etc. When carrots are cooked and exposed to oil during cooking, beta-carotene can be absorbed by the body to the greatest extent. Eating it raw will waste nutrients, and it is not recommended to squeeze juice, which will waste beneficial nutrients. healthy of dietary fiber.

　　3. Starchy vegetables

　　For example, do not eat potatoes, yams, sweet potatoes, and taro raw as they will be difficult to digest. If these foods are eaten raw, not only will the starch and other nutrients in them not be easily digested by the human body, but it will also cause discomfort such as bloating. Cruciferous vegetables such as broccoli and cauliflower are rich in dietary fiber. When cooked, they not only taste better but are also easier for the human body to digest.

　　4. Lentils and other beans are easily poisoned if eaten raw.

　　Most beans, such as lentils, kidney beans, and sword beans, are not suitable for eating raw. This is because the saponins in the lentil skin and the hemagglutinin in the beans are both highly irritating to the gastrointestinal tract. Saponin, also known as saponin, is a poisonous protein in itself. The two ends of beans, pod silk and old lentils have the most toxins. When cooking beans, they need to be cooked thoroughly to destroy their toxins. Even if they are served cold, they must be cooked in boiling water for at least 10 minutes.

　　Never eat five kinds of vegetables with the skin on

　　Many people believe that there are a lot of nutrients in the peels of fruits and vegetables, so the peels of any fruits and vegetables should be eaten. However, there are some fruits and vegetables that are easy to cause disease when eaten. disease or poisoning, so avoid eating the peels of these fruits and vegetables.

　　Potato skins contain "glycoalkaloids", which can cause poisoning after accumulating to a certain amount in the body. Because the poisoning caused by it is chronic and the symptoms are not obvious, it is often ignored.

　　Potatoes, due to the different concentration of gastric acid required for digestion of this food, will prolong the retention time of food in the stomach, prolong the time of gastrointestinal digestion and absorption, and cause gastrointestinal discomfort.

　　Persimmon Skin: When persimmons are immature, tannic acid is mainly present in the persimmon flesh, while when mature, tannic acid is concentrated in the skin. After tannic acid enters the human body, under the action of gastric acid, it will combine with the protein in the food to form a precipitate called persimmon stone, which can cause a variety of diseases.

　　Sweet potato skin contains a lot of alkali, and eating too much can cause gastrointestinal discomfort. Sweet potato skins with brown and dark brown spots are infected by the "Black Spot Bacteria", which can produce "Isopotone" and "Ipocartonol", which will damage the liver and cause poisoning when entering the human body. Those with mild poisoning may experience nausea, vomiting, diarrhea , severe cases can lead to high fever, headache, asthma, convulsions, vomiting blood, coma, and even death.

　　Water chestnut skin Water chestnut skin often grows in paddy fields, and its skin can collect harmful and toxic biological excretions and chemical substances. In addition, water chestnut skins also contain parasites. If you eat unwashed water chestnut skins, you will get sick.

　　The peel of Ginkgo biloba contains toxic substances such as "white fruit acid", "hydrogenated white fruit acid", "hydrogenated white fruit acid" and "white fruit alcohol", etc., which will damage the central nervous system after entering the human body. nerve system, causing poisoning. In addition, it is not advisable to eat too much cooked ginkgo meat.
