Some scholars believe that there are 7 cultivated varieties of potatoes, which are mainly distributed in the temperate and subtropical regions of the Andes Mountains in South America and the coastal areas nearby. The most important cultivated potato variety is the tetraploid variety. The tetraploid cultivated potato spread all over the world. Initially, the short-day type was introduced from Colombia in South America to Spain in Europe in 1570. After artificial selection, it became a long-day type; later it spread to Asia, North America, southern Africa, Australia and other places. Potatoes have high yields, rich nutrition, and strong adaptability to the environment. They are now all over the world. Tropical and subtropical countries can even cultivate them in winter or cool seasons and obtain high yields.
Nutritional value
Potatoes, sweet potatoes, taro and other potato foods are rich in nutrients. They contain much more protein and vitamin C, vitamin B1 and vitamin B2 than apples. They also have high calcium, phosphorus, magnesium and potassium content, especially potassium, which ranks first among vegetables. Potatoes contain a lot of high-quality fiber, which can prevent constipation and prevent cancer. So, how can we eat potatoes well?
First of all, we must ensure the quantity. We should eat about 80 grams of potato foods (potatoes, sweet potatoes and taro) every day. Secondly, we should match meat and vegetables well. As long as the combination is good, we can enjoy delicious food while maintaining a slim figure. When eating potatoes, we should reduce the intake of staple food accordingly. The ratio of potatoes to staple food can be controlled at 3:1 to 4:1. If we eat about 80 grams of potato foods every day, it may help reduce the risk of stroke.
As for mashed potatoes and French fries, which are more common in fast food, they are oxidized during the processing, destroying a lot of vitamin C and greatly reducing the nutritional content. As 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 substances. Ring monomer polymers are carcinogenic substances, so try to eat less.
Nutritionists point out that there is no need to worry about excess fat when eating potatoes, because it only contains 0.1% fat, which is the least among all hunger-filling foods. Eating more potatoes every day can reduce fat intake and gradually metabolize excess fat.
