As we all know, potatoes do not have many calories, not only do they not make people fat, but they are also an ideal diet food. According to the nutritional analysis, the edible parts in each100g of potato contain 2.6g of protein, 0.04g of fat, 5.76g of carbohydrate/kloc-0, 0.0mg of iron/kloc-0, 0.0mg of calcium, 2.6mg of sodium, 224mg of potassium and 34mg of vitamin C.
The carbohydrate content in potato is only 1/4 of that of grain. Although the calcium content is not as high as that of other vegetables and some grains, the vitamin C content in potato is not as good as that of ordinary food, so potato is a good food with both grain and vegetable. The Agricultural Research Institute of the United States Department of Agriculture believes that "you can get the required nutrition by eating only whole milk and potatoes every meal." Another notable feature of potatoes is their high potassium content.
According to Professor Zhao Guangsheng from Shanghai Institute of Hypertension, there are many ways to lower blood pressure. Calcium supplementation can lower blood pressure, and salt restriction and potassium increase can also lower blood pressure. He believes that patients with hypertension have low urinary potassium, especially those who take diuretics, and their blood potassium is lost. Potassium supplementation has a unique protective effect on blood pressure. According to the survey, there are almost no hypertensive patients whose staple food is potatoes in Guizhou mountainous areas. You can see the effect of potatoes.
