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 among all hungry foods. Eating more potatoes every day can reduce fat intake and gradually metabolize excess fat. So eating potatoes often won't make you 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. The alkaloids in potato belong to steroidal glycoside alkaloids, mainly solanine and solanine. Its structure is similar to human steroid hormones, such as androgen, estrogen and progesterone. 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.
