Cooking potatoes usually takes 10 minutes to 15 minutes. But it depends on the size, quantity and temperature of potatoes. If you cook a plate of small potato pieces in an ordinary pot, it will take about three to five minutes to cook on high fire. If you cook four or five medium ones in an ordinary pot, it will take fifteen to twenty minutes.

Eating a little immature potatoes will not reach the level of poisoning, but if you eat too much, it will cause abnormal disharmony between the stomach and intestines, which may cause nausea, vomiting, diarrhea and other discomfort. In addition, potatoes contain an ingredient called lectin, which is harmful to human body. It may cause abdominal pain, diarrhea, nausea and vomiting after eating. After cooking, this toxicity will gradually disappear, but if it is not cooked, it is likely to cause intestinal irritation after entering the human body.

Precautions for eating potatoes

1, don't eat with skin. Potatoes contain a toxic substance called solanine. If people eat a lot of solanine, it will cause acute poisoning. Solanine is mainly concentrated in the skin. Generally speaking, yellow-skinned potatoes contain the least solanine, followed by purple and green skins. The darker the color, the more toxins. Therefore, when eating potatoes, you must peel them, especially to peel off the green peel or dig out the bud. If it is serious, you can also throw away the potatoes.

2. Cook properly. Don't fry potatoes, it will increase calories and make potatoes lose nutrients, which is counterproductive. Can be made into mashed potatoes, potato salad, etc. Try to cook potatoes in a light way. Fried meat with potatoes is a very oil-consuming dish. According to measurement, a medium-sized potato has only a few kilocalories, but after frying, it has more than 200 kilocalories after being made into French fries. Therefore, potatoes themselves do not have a lot of calories, but the oil absorbed by potatoes can lead to obesity.
