Moreover, cold potatoes are rich in soluble dietary fiber - fructooligosaccharides, which not only provide a sweet taste for cold potatoes, but also promote the growth and reproduction of intestinal probiotics, delay the absorption of fat and sugar in the intestines, and are very beneficial to improving intestinal health, promoting intestinal peristalsis, and assisting in regulating blood sugar and blood lipids.

Eat cold potatoes
These details should be taken care of
First, don't eat too many cold potatoes at once.
Considering that the content of dietary fiber and fructooligosaccharides in cold potatoes is not low, if too much is eaten at one time, it may cause diarrhea due to excessive promotion of intestinal peristalsis. This is probably the origin of the word "cool" in the name of the cold potato.
Second, don't touch the leaves, flowers, pods, and beans of cold potatoes.
Unlike other legumes, the leaves, flowers, pods, and beans of the cold potato are not only inedible, but they are also poisonous, containing a toxin called rotenone.
This toxin can block the use of oxygen by human cells, and once it is ingested in excess, it will gradually cause nausea, vomiting, difficulty breathing, purple lips, decreased blood pressure, coma and other symptoms due to lack of oxygen in the cells, and may even cause death in severe cases.
However, generally the cold potatoes we see in the market only have the root parts, and there is no risk of poisoning. If you see cold potatoes in the wild, remember not to touch them.
