Potato, the scientific name of potato, is native to Peru, 1650, and has been cultivated in Taiwan Province province of China. The earliest written record is the record of Songxi County, Fujian Province, which is the thirty-ninth year of Qing Emperor Kangxi, that is, 1700. 1848, Wu, the governor of Shaanxi Province, wrote Textual Research on Plant Names, which recorded that "potatoes produced in Guizhou and Yunnan-? Shanxi is planted as a field, popularly called yam egg, which is extremely huge.

Potatoes are closely related to people's lives. Engels wrote such a thing in "From Ape to Man": "1847, there was a great famine in Ireland due to potato cold,10 million Irish people who lived on potatoes starved to death, and 2 million people fled overseas."

Potato has the characteristics of high yield, early maturity, wide distribution and many uses, and can become the world food. It contains complete nutrients, can meet 95% of all nutritional needs of human body, and its calorific value is higher than that of all cereal crops. It contains protein 1.9%, fat 07%, carbohydrate 16%, mineral l.2%%, and also contains iron, calcium, phosphorus, carotene, anti-scurvy, vitamin C and crude fiber, so some people say that potato is a perfect dish. It can be used for brewing wine, making vinegar, extracting alcohol and monosodium glutamate, making glucose, maltose, malt extract, citric acid, lactic acid, starter, etc.

As a medicine, potato has the functions of invigorating qi, invigorating spleen, regulating stomach, diminishing inflammation and relieving pain, and can be used externally to treat eczema. Chinese medicine says: potatoes are sweet and flat, and have the effects of harmonizing stomach, invigorating spleen and qi, detoxifying and diminishing inflammation. Can be used for treating epigastric pain, fatigue and constipation. Compendium of Materia Medica is written like this; "Functional thin pox, children's cooked food, poxvirus solution".

Shanxi fellow villagers said: "the yam egg treasure is a treasure, and a meal can't be separated." People have many ways to eat potatoes. In potato-rich areas, it is usually eaten with oatmeal; Every region has its own emphasis on solo food. Machining and making rough surfaces. Making vermicelli and bean jelly is more common.

Potato meal not only helps you to be happy, but also can lose weight. According to nutritional medicine research, potatoes only contain 0. 1% fat, which is the least content in all foods. At the same time, potatoes also contain many nutrients that the human body needs, such as carbohydrates, vitamins, calcium, magnesium and potassium. It is more comprehensive than rice noodles, and even apples with high nutritional value are dwarfed.

From the point of view of nutrition, the nutritional value of 1 kg potato is about equivalent to 4 kg apple. Therefore, a German nutritionist asserted: "As long as you eat milk and potatoes at every meal, you can get all the nutrients you need."

American nutritionists advise dieters to eat more grains and potatoes. Both potatoes and sweet potatoes contain starch, but their water content is as high as 70% or more, and the real starch content is only 20%, which also contains "dietary fiber" that can produce "satiety", so using them instead of staple food can reduce weight.

Why are potatoes still regarded as fattening foods?

First, people make good potatoes into French fries and chips because of improper cooking.

Anyone who has done "roast meat with potatoes" knows that it has a strong oil absorption ability. According to the measurement, a medium-sized "French baked potato" without oil contains only a few thousand calories, while the heat energy contained in French fries is more than 200 kilocalories. What makes people fat is not the potato itself, but the oil it absorbs.

Second, people don't use potatoes instead of staple food, but treat them as vegetables. Potatoes contain less heat energy than staple food, but more than ordinary vegetables. Therefore, eating potato vegetables is easier to get fat than eating green vegetables.

According to China's traditional view, potato is just a kind of food with a lot of starch, but it is really nutritious. In addition to the common shredded potatoes, fried potato chips and potato beef, potatoes can also be made into cold or hot mashed potatoes and potato salad. Using your brains to make ordinary potatoes into different dishes will add a lot of color to your life.

In Yong 'an Xili, Jianguomen, Chaoyang District, Beijing, there is a "Sanhe Fresh" restaurant, which specializes in home cooking. Other dishes taste just so-so, but I like the mashed potatoes made here best. 13 yuan, it's really delicious.

There is also a "Northeast Hunter Cuisine" restaurant in Fuchengmen, Xicheng District. The stewed beef with potatoes is only 16 yuan, which is cheap and good.

Compared with Chinese food, it should be admitted that potato dishes in western food are more authentic. In Bavaria, Germany, there is a special dish: "Picher Stein", which is potato soup stewed with potatoes, three kinds of meat and seven kinds of vegetables. This dish is full of color, flavor and flavor. Similarly, in Berlin, people stew potatoes with bacon and sausages with spices. In Falc, potatoes are cooked with celery and cream. Plus two sausage and potato salads, everywhere.

The most popular German restaurant in Beijing is the German beer house in Kempinski Hotel. In addition to your own beer house, there is also a potato meal cooked with potatoes, apples and cooked black sausages, which is a good food for people who want to have a happy mood.

The famous Hard Rock Restaurant and Friday Restaurant in Beijing are popular places for young people. Do you know why there is always laughter there? Look at the food served there. Potatoes mixed with mayonnaise are a cold food. When potatoes are lukewarm, they are served with vinegar sauce and onions. It's delicious, and there are many French fries that make you unhappy.

Potatoes, sweet potatoes, taro and other potato foods are rich in nutrition. The contents of protein, vitamin C, vitamin B 1 and vitamin B2 are much higher than those of apples, and the contents of calcium, phosphorus, magnesium and potassium are also very high, especially the content of potassium, which can be said to be the first among vegetables. Potatoes contain a lot of high-quality cellulose, which can prevent constipation and cancer. So, how to eat potatoes to eat well?

First of all, we must ensure the quantity. Eating potato foods (potatoes, sweet potatoes and taro) should be about 80 grams per day. Secondly, the combination of meat and vegetables is good. As long as the combination is good, you can enjoy delicious food and achieve the goal of keeping slim. When eating potatoes, the intake of staple food should be reduced accordingly, which can be controlled according to the ratio of potatoes to staple food of 3 ∶ 1 ~ 4 ∶ 1. If you eat about 80 grams of potatoes every day, it may help reduce the risk of stroke.

For many mashed potatoes and chips in fast food, they are oxidized during processing, which destroys a lot of vitamin C and greatly reduces the nutritional components. For French fries, it is easy to increase the intake of fat, and it is difficult to judge whether the oil of French fries is fresh. In addition, repeated high-temperature heating will produce polymers, such as toxic cyclic monomers, which are carcinogens. Try to eat less.

Nutritionists point out that eating potatoes does not need to worry about excess fat, because it only contains 0. 1% fat, which is the least among all hungry foods. Eating more potatoes every day can reduce fat intake and gradually metabolize excess fat.

However, it is worth noting that potatoes, especially potatoes, contain a toxic substance called alkaloids, which can cause poisoning, nausea, diarrhea and other reactions when ingested in large quantities. This toxic compound is usually concentrated in the potato skin, so you must peel it when eating, especially when peeling the green skin. In addition, potatoes with buds are more toxic. When eating, you must dig out the buds and roots and soak them in clear water. Stewing should get angry.

In addition, if pregnant women often eat potatoes with high alkaloid content, accumulation in the body may lead to fetal malformation. Of course, there are considerable individual differences between people, and not everyone will be abnormal after eating potatoes. However, it is best for pregnant women not to eat or eat less potatoes, especially potatoes that have been stored and germinated for a long time, which is especially important for women in the early pregnancy.
