Sweet potato planting Jinyun county has a long history, and the climate and soil are very suitable for sweet potato planting. Therefore, every household has the habit of planting sweet potatoes, with a planting area of several thousand mu. At the same time, Dayang, Fangxi and other mountainous areas have become ecological food because of their unique geographical environment and pollution-free. Especially from the recent books and periodicals, Professor Lin Hongsheng, deputy director of the National Cancer Center of Traditional Chinese Medicine, told the reporter that sweet potato is not only nutritious, but also ranks first among anti-cancer foods. There are many introductions in this document. The list of 20 kinds of anticancer vegetables published by National Cancer Research Center of Japan is: sweet potato, asparagus, cauliflower, Chinese cabbage, broccoli, celery, sweet pepper, carrot, cauliflower, amaranth, shepherd's purse, kohlrabi, mustard tuber, tomato, green onion, garlic, cucumber, Chinese cabbage and so on. Among them, sweet potato ranks first.

Medical workers in China investigated the hometown of centenarians in western Guangxi, and found that all the longevity elders here have a common feature, that is, they are used to eating sweet potatoes every day, even taking sweet potatoes as their staple food. The anticancer mechanism of sweet potato is not very clear, and opinions vary. It is reported that the hospital in Philadelphia, USA, extracted an active substance-androsterone from sweet potato, which can effectively inhibit the occurrence of colon cancer and breast cancer. Another American university study found that there is a substance called dehydroepiandrosterone in sweet potato, which has a definite effect on preventing and treating cancer. Professor Zhang from the Health Room of Beijing University of Chinese Medicine believes that sweet potato has a certain anti-cancer effect, but its anti-cancer "ability" should not be exaggerated and should be treated dialectically, because its mechanism of action has not been fully clarified, and the greatest role of sweet potato should be on losing weight, bodybuilding, preventing sub-health, relaxing bowels and detoxifying. Regarding the anti-cancer effect, Chinese medicine theory holds that it can reduce the accumulation of garbage and toxins in the human body because of its catharsis and detoxification. In this regard, Professor Song Santai, director of the Cancer Center of China Academy of Military Medical Sciences and deputy director of the Cancer Professional Committee of the whole army, also believes that the mechanism and reason of sweet potato's anti-cancer has not yet been scientifically tested. Theoretically, it is speculated that it is rich in dietary fiber, which is beneficial to prevent cancers such as colon cancer.
