Second, how to eat potatoes and matters needing attention
1, the potato skin turns green and can't be eaten.
If the potato skin turns green, it means that the solanine content is high. Be careful when eating this kind of potato, not only peel it, but also cut off more pulp and completely remove the green part. If the green part of potato skin is large or has sprouted, don't eat such potatoes, otherwise it will easily lead to food poisoning.
2. You can't eat potatoes when they sprout.
When potatoes turn green, germinate or rot, the content of solanine will increase greatly. Eating a very small amount of Solanum nigrum is not necessarily harmful to human body, but if you eat 0.2-0.4 grams of Solanum nigrum at a time, it may cause poisoning.
Therefore, after eating germinated potatoes, symptoms of food poisoning such as nausea, vomiting, abdominal pain, dizziness and dyspnea may occur. After sprouting, solanine may still remain in the green tuber, which may also cause poisoning, so it is not suitable to eat sprouted potatoes.
If the surface of a potato is moldy and blue, or a potato has several buds, it should be thrown away without hesitation. Even if the buds are cut off, this kind of potato is not poisoned, with little nutrition left and poor taste.
3, refurbished potatoes can not be eaten
Most problem potatoes have the same "face": smooth appearance, little or no soil, short storage time and perishable. These fresh and shiny potatoes are actually "refurbished and washed" potatoes. Experts say eating refurbished potatoes is easy to be poisoned.
What looks bright on the outside is actually "washed potatoes" Compared with normal potatoes, washed potatoes are easy to rot, and if you eat spoiled or bacterial infected potatoes, it will cause harm to the human body.
Experts remind that when buying potatoes, try to avoid picking potatoes with long buds, blue skin or rotten skin. If the potatoes sprout slightly and turn green, dig out the buds, eyes and blue parts before eating, and be sure to cook them before eating. When cooking, you can add some vinegar to accelerate the destruction of solanine.
4. What can't potatoes be eaten with?
1, potato+persimmon
After eating potatoes, people will produce a lot of hydrochloric acid in their stomachs. If they eat persimmons again, persimmons will precipitate under the action of gastric acid, making it difficult to digest and excrete.
2, potatoes+tomatoes
Potatoes produce a lot of hydrochloric acid in the gastrointestinal tract of human body; Tomato will produce insoluble precipitate in water in strong acid environment, which will lead to poor appetite and indigestion.
3, potatoes+bananas
Potatoes are the food that often appears on our table, and bananas are the fruits that we often eat. Maybe many people don't know that using them together will have side effects. If the two foods are eaten together or less than 15 minutes apart, the elements contained in them will react chemically and produce certain toxins. These toxins can make people grow spots. Remember, Amy, don't eat these two foods together.

5. How to eat potatoes is the most nutritious?
1, first place: steamed potatoes.
Steamed potatoes are the most ideal cooking method, which has little effect on nutrition and can retain natural flavor. Studies have shown that the loss of vitamin C after potato steaming is very small, and the retention rate is above 80%, but there is no loss of carbohydrates, minerals and dietary fiber, and the starch particles in it will be fully gelatinized, which will be more easily digested and decomposed in the body and will not bring a burden to the gastrointestinal tract.
Cooking tips: Steamed whole potatoes with skin have less nutrient loss, especially more vitamin C, which is the best way to eat.
2. Second place: Mashed potatoes.
Potatoes are steamed and pressed into mud, which is tender and smooth, and more suitable for the elderly and children. After reasonable collocation, it can also be used as diet food for people who need to control their weight, blood sugar and blood pressure. But some improper collocation will destroy the nutritional and health care function of mashed potatoes. For example, a lot of margarine, artificial pigment, essence and sugar are added to the "milk-flavored mashed potatoes" in some foreign fast food, which greatly reduces the nutrition of mashed potatoes.
Cooking Tips: Yogurt and nut mashed potatoes are recommended. They are not only delicious, but also add protein and minerals after adding yogurt and nuts. They are more nutritious and are good snacks. Nuts can be walnuts, cashews and peanuts.
3. Third place: Braised potatoes.
Potatoes are cut into large pieces, with fewer knives and fewer sections, so the loss of water-soluble vitamins, such as vitamin C and B vitamins, is also less. But when some people stew potatoes, they will fry them first, which will taste better, but it will destroy many valuable nutrients.
Cooking tip: Potato roast beef is a perfect match. Potatoes lack minerals such as iron and protein, while beef is rich in these nutrients. Beef lacks carbohydrates and vitamin C, and contains cholesterol. Potatoes can not only make up for the shortage of beef, but also contain rich dietary fiber, which can reduce the body's absorption of cholesterol.
4. Fourth place: fried potato chips.
After potato slices are cooked, some nutrients will be lost. However, the cooking time of fried potato chips is generally short, which can make up for the shortage to some extent.
Cooking tip: Don't use blisters before frying potato chips. Soaking will lose more nutrients.
5. Fifth place: Fried shredded potatoes.
Thin slices of potatoes will lead to a lot of nutrient loss. Moreover, most people soak the shredded potatoes in water before frying them, and some even blanch them first and then rinse them with cold water. These practices will make rich vitamin C and inorganic salts such as potassium and magnesium dissolve in water and lose. Moreover, the fried potato chips will absorb more oil because of their large cross section and increased surface area.
Cooking Tips: Putting vinegar early can not only improve the taste, but also improve the absorption rate of protein, calcium, vitamin C and other nutrients ... Putting salt late, on the one hand, it will soften potato shreds, on the other hand, it will increase the loss of vitamin C, and if it is put too early, it will increase the intake of sodium.
