Potatoes are rich in carbohydrates, protein, vitamin A, vitamin B, vitamin C, cellulose, calcium, magnesium, potassium and other nutrients, with low fat content and high nutritional value, and are known as the "second bread" of human beings. The cellulose in potatoes is tender, which will not cause any adverse stimulation to the baby's gastrointestinal mucosa and is easy to digest. It is an ideal food for babies to prevent constipation.

Second, the efficacy of potatoes

1, the main component of potatoes is carbohydrates, but potatoes are not high in calories and rich in vitamins and minerals. Eating not only has a good feeling of fullness, but also does not increase excess calories. To put it bluntly, it is not easy to gain weight when you are full.

2. The content of vitamin C in potato is about 10 times that of the same apple, and the content of vitamin B is about 4 times that of the same apple. In general, vitamin C is very easy to be destroyed after high temperature, while vitamin C in potatoes can be well protected from being destroyed under the protection of starch after high temperature.

3. There are many resistant starches in potatoes, which can effectively promote bile secretion and thus lower cholesterol. Usually, when cooking, we like to remove the starch from the cut potatoes by water to increase the crispness of the potatoes, but this method will cause the loss of resistant starch.

Potatoes are not only yellow, but also purple and red. The antioxidant effect of anthocyanin in purple potato beans is four times that of vitamin C, and yellow potato contains β -carotene with high potassium content. Red potatoes contain red pigment and high content of vitamin C.

Healthy eating method of potatoes

1 First of all, we must ensure the quantity. We should eat about 80 grams of potato food (potatoes, sweet potatoes and taro) every 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.

2. Many mashed potatoes and chips in fast food were oxidized during processing, which destroyed a lot of vitamin C and greatly reduced 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.

3. Nutritionists point out that you don't have to worry about excess fat when eating potatoes, because it only contains 0. 1% fat, which is the least satisfying hunger among all foods. Eating more potatoes every day can reduce fat intake and gradually metabolize excess fat.

4. According to foreign reports, the newly harvested potato alkaloids are 20 ~ 80 mg per kg, and after storage for a period of time, they rise to 75 ~ 1 14 mg. The alkaloid content of germinated or moldy potatoes will further increase. This toxic compound is high in potato skin, so peel it when eating, especially peel off 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.
