Nutrition and Edible Methods of Potato

The nutritional value of potato itself is not bad, rich in potassium, and the content is equivalent to that of banana; Vitamin c is also very rich, comparable to tomatoes; It is rich in vitamin B 1, which China people are easy to lack, and the content of vitamin B2 is also higher than that of rice. It also contains dietary fiber and polyphenols. Without oil and salt, the starch content of baked potatoes and steamed potatoes is not as high as that of rice steamed bread, and the speed of raising blood sugar is not as fast as that of white rice steamed bread, so they feel full. Eating the same 300 kcal food, potatoes are more likely to make people feel full than rice, steamed bread and bread.

If you simply make baked potatoes and steamed potatoes, the health value of potatoes is not disappointing. Taking them as staple food is conducive to improving nutrition and controlling blood pressure. Baked potatoes are the common staple food of French and Germans.

But the problem is that most people in China eat potatoes as a dish. If you cook with potatoes, the effect will be reversed. Among vegetables, the starch content of potatoes is almost the highest, usually between 14%-20%, while the carbohydrate content of most vegetables is below 5%, and the green leafy vegetables are even lower. More starch means more calories. If potatoes are used instead of vegetables, there is no doubt that the risk of obesity will increase.

What's more, most people in China don't eat baked potatoes and steamed potatoes, but cook potatoes with a lot of oil or stew them with meat. Potatoes after oil absorption contain considerable calories.

In addition, when potatoes are eaten as vegetables, there is another serious defect. Vegetables are divided into "dark vegetables" and "light vegetables", and potatoes belong to light vegetables. Light color means low carotenoid content and low anthocyanin content. No matter carotenoids, folic acid, vitamin K, calcium, dietary fiber, antioxidants and many other aspects, it can not be compared with dark green leafy vegetables.

Studies on food safety also found that potatoes are the vegetables that are most prone to produce acrylamide (a suspected carcinogen) in cooking. The more fragrant potatoes are cooked, such as frying and frying, the more acrylamide is produced. Potato chips rank first in acrylamide content in common foods. The researchers explained that this is because potatoes are rich in glutamine and asparagine, and acrylamide is easily produced under the cooking conditions of 120- 190 degrees Celsius. Boiled potatoes do not have this problem, because even if cooked in a domestic pressure cooker, the cooking temperature is only less than 120 degrees Celsius.

In a word, I suggest you change the way you eat potatoes and replace some rice with steamed potatoes. If you are worried about the bad taste, you can add some salt and pepper to eat, which is delicious, or cut the steamed potatoes into small pieces, put them in your rice bowl and eat them normally.

Which potatoes can't be eaten?

First of all, moldy potatoes

Many people find that the surface of potatoes is moldy, but they don't care, because there is nothing unusual about potatoes after this layer of mold is washed away, but please note that moldy potatoes must not be eaten, because they will contain some mold, and the harm caused by mold entering the body must be needless to say, as everyone knows. Therefore, in addition to sprouting too much potatoes, moldy potatoes can't be eaten.

Second, green potatoes.

Generally speaking, potatoes should be orange-yellow, but potatoes are blue and green. Don't eat even a little, because this potato is probably caused by excessive toxic alkaloids. People are prone to food poisoning after eating this kind of potato, which is why in some food poisoning incidents, potatoes have not germinated, but they are still poisoned.

Third, rotten potatoes

Some friends will treat rotten potatoes as sprouted potatoes, but please be careful. Even if you cut off the rotten part, you can't eat it, because rotten potatoes also contain a lot of solanine. If you don't pay attention, it will easily lead to human injury and even death.

Four, potatoes with wounds

What kind of potato has a wound? Mainly depends on whether there is a black bruise on the potato skin. If there is, then it is best not to eat this kind of potato, because the wound will lead to the loss of water in the potato, greatly reducing the nutritional value of the potato, and may also lead to deterioration. People are easy to damage their bodies after eating.

5. Potatoes that germinate too much

If the potatoes germinate too much or turn blue seriously, this method can't be used. If the potato germinates too much, even one third of a potato has germinated, which means that solanine has spread around the potato bud. Even if the buds are dug out, a lot of solanine will remain in this potato, which will cause food poisoning for people.
