Introduction of potato (potato)
Potato, Solanum of Solanaceae, panicum miliaceum, also known as potato, sweet potato, potato, etc. The artificial cultivation of potatoes can be traced back to southern Peru from about 8000 BC to 5000 BC.
Potatoes, height 15-80 cm, glabrous or puberulent. The stem is divided into two parts: aboveground stem and underground stem. Potato is one of the five staple foods in China, with high nutritional value, strong adaptability and large yield. It is the third most important food crop in the world, second only to wheat and corn.
Nutritional value of potatoes;
1, potatoes have anti-aging effect. It is rich in B vitamins such as vitamin B 1, B2, B6 and pantothenic acid, and a large amount of high-quality cellulose, as well as trace elements, amino acids, protein, fat and high-quality starch.
2. Potatoes are rich in dietary fiber. According to some data, their content is as much as that of apples. Therefore, the gastrointestinal tract absorbs potatoes slowly. After eating potatoes, it stays in the intestines for much longer than rice, so it is more full, and it can also help take away some oil and garbage, which has a certain laxative and detoxification effect.
3. Potatoes are carbohydrates, but their content is only about 1/4 of the same weight of rice. Studies have shown that the starch in potatoes is a kind of resistant starch, which can shrink fat cells. At the same time, potatoes contain almost no fat, and the fat content of 100g potatoes is only 0.2g.
4. Potato is a very good food with high potassium and low sodium, which is very suitable for obese people with edema. In addition, its potassium content is almost the highest among vegetables, so it also has the effect of stovepipe.
Taboo of potatoes:
1, eat potatoes with green skin.
Many people eat potato skins when they turn green, but the green potatoes indicate that the content of solanine is high. At this time, you must be careful when eating potatoes. Not only do you need to peel, but you also need to cut off some pulp and completely remove the green part. If the green part of the potato skin is large or has sprouted, don't eat such potatoes, otherwise it is easy to get food poisoning.
2. Eat potatoes and tomatoes.
Potatoes are very particular about how to eat potatoes. If you don't pay attention at ordinary times, even if potatoes are good, they will be unhealthy if they are not properly matched with other foods. Among them, the most common thing is to eat them with tomatoes, because potatoes will form more hydrochloric acid in the gastrointestinal tract, and too strong acidity will make tomatoes precipitate because they are insoluble in water, thus making people indigestion and loss of appetite after eating.
3. Eat potatoes with bananas.
Eating bananas and potatoes together will make freckles appear on your face.
4. Potatoes can't be eaten when sprouted.
If you cook germinated potatoes, eating them will often make people vomit and chill, resulting in poisoning. This is because potatoes produce a highly toxic substance called solanine around the sprouting eyes, which people will be poisoned if they eat it. As long as the potatoes around the bud eyes are dug up, you can eat them boldly and safely without causing poisoning. (Note: Now scientists have invented a plant growth stimulator called methyl α-naphthylacetate, and spraying it on potatoes can stop potatoes from sprouting during storage. )
