Everyone who has lived in the city knows that a small purple potato can sell for 5 yuan or more in winter, but because it tastes good, it can also play the role of losing weight, preventing constipation, preventing cancer and protecting eyes, so everyone will not care too much about those few dollars.
But you should also pay attention to eating purple potatoes. How much do you know about the four taboos of purple potato?
First, you can't eat it raw.
People with poor gastrointestinal function should pay attention. Eating cold sweet potatoes is easy to cause gastrointestinal discomfort, because if sweet potatoes are not steamed, the starch particles in the body will be difficult to digest without being destroyed by high temperature, so eating sweet potatoes must be cooked and eaten while it is hot!
Second, you can't eat purple potatoes with dark spots.
The black spot on purple potato indicates that it has been infected by black spot pathogen. The substances secreted by Alternaria alternata cannot be destroyed by high temperature. Eating too much will be harmful to the human liver and even cause acute poisoning.
Third, don't eat with sweet things.
The combination of purple potato and sweets will increase the probability of gastroesophageal reflux, because purple potato itself is sweet. If eating purple potato alone is too monotonous, you can eat it with protein and fatty food, because purple potato itself does not have those two substances, so this collocation can play a role in balancing the diet.
