Does sweet potato help prevent cancer? Why does eating sweet potato with skin cause cancer?
At present, among 20 kinds of vegetables that have obvious inhibitory effect on tumor cells, sweet potato ranks first, with the cancer inhibition rate of cooked sweet potato being 98.7% and raw sweet potato being 94.4%. Studies have found that sweet potatoes contain anticancer substances that inhibit the growth of cancer cells, called glycolipids; There is also an active substance in sweet potato called deoxyandrosterone, which can inhibit and kill cancer cells, revive the weak immune system and prevent and treat breast cancer and colon cancer.
In recent years, there have been many studies on sweet potato, and more and more people have discovered the nutritional value of sweet potato, especially in anti-cancer. Many people call them "anti-cancer stars", so sweet potatoes are greatly touted, and more people like to eat sweet potatoes. But it is the fleshy part of sweet potato that can prevent cancer more. If you eat the skin together, it will not only prevent cancer but also cause cancer, which is probably unheard of before. Why is this?
In fact, eating sweet potatoes with skin is easy to cause cancer mainly because of land pollution. Under normal circumstances, sweet potato skin can also be eaten. However, due to the serious land pollution in China, the solar calendar contains a lot of heavy metals and some toxic substances, and sweet potato belongs to root food, which grows in the soil for a long time, and the skin is the part that absorbs the most of these pollutants. So it's best not to eat skin. In addition, people like to eat baked sweet potato in winter, but don't eat the skin of baked sweet potato, because baked sweet potato mostly uses coke as fuel, and harmful substances such as sulfur dioxide are easy to accumulate in the skin of sweet potato, so eating baked sweet potato with skin has cancer risk.
