Advantages and disadvantages of eating potatoes
Potatoes, also known as potatoes, are rich in starch, pectin, protein, potassium, citric acid, vitamin B and C dietary fiber. Eating potatoes regularly can prevent hypertension.

1, prevention of stroke: potatoes are rich in B vitamins and high-quality cellulose, which plays an important role in delaying aging. Potatoes are rich in dietary fiber and sucrose, which is helpful to prevent and treat digestive tract cancer and control the content of cholesterol in blood. Among them, protein can prevent cardiovascular diseases. Like other foods rich in potassium such as bananas, apricots and peaches, potatoes can reduce the risk of stroke without any side effects.

2, lose weight: First of all, eat potatoes without worrying about excess fat, because it only contains 0. 1% fat, which is beyond the reach of all other hungry foods. Eating more potatoes every day can reduce fat intake and gradually metabolize excess fat. Secondly, eating potatoes does not have to worry about single nutrition and is harmful to health. Potatoes contain second to none high-quality protein, which is not inferior to soybeans in both nutritional value and health care function; Even other nutrients needed by the human body, such as carbohydrates, various vitamins and minerals, are more comprehensive than rice noodles. In recent years, Italy, Spain, the United States, Canada, Russia and other countries have sprung up a number of potato dietotherapy restaurants with unique flavors to meet the daily needs of bodybuilders and dieters.
When potatoes germinate, they produce a toxin called solanine. Good quality potatoes only contain 100 mg of solanine per 100 g, while solanine in green, germinated and rotten potatoes can be increased by more than 50 times. Eating a very small amount of Solanum nigrum is not necessarily harmful to human body, but if you eat 200 mg of Solanum nigrum (about half a dozen potatoes that have turned green and sprouted) at a time, it will take 15 to 3 hours to get sick. The earliest symptoms are itchy mouth and throat, epigastric pain, nausea, vomiting and diarrhea. Those with mild symptoms will heal themselves after 1 ~ 2 hours through their own detoxification function. If you eat more than 300 ~ 400 mg of Solanum nigrum, the symptoms will be very serious, such as dehydration and repeated vomiting caused by rising body temperature, dilated pupils, fear of light, tinnitus and so on. Therefore, patients with severe symptoms should be sent to hospital for treatment as soon as possible.
Attention must be paid to prevent potato solanine poisoning;
1, do not eat immature green potatoes.
2. The part that has sprouted and turned blue and the rotten part on the potato should be thoroughly removed. If the blue area of potatoes is large and there are many sprouted parts, they should be thrown away.
3. Cut the peeled potatoes into small pieces and soak them in cold water for more than half an hour to make the remaining solanine dissolve in water.
4. Using the weak alkalinity of Solanum nigrum, adding proper amount of rice vinegar when cooking potatoes, and decomposing Solanum nigrum with the acidity of vinegar can play a detoxification role.
5. Boiled potatoes should be crispy and thoroughly burned. Long-term high temperature will partially decompose solanine.
If you feel a little numb in your mouth when eating potatoes, it means that potatoes still contain more solanine, so you should stop eating them immediately to prevent poisoning.
It is reported that if pregnant women eat too much Solanum nigrum, the fetus may be deformed, so pregnant women should be especially careful.
