Chen, an expert in the vegetable group of Jinhua Academy of Agricultural Sciences, said that he had never heard that eating too much purple sweet potato would cause cancer. He explained that purple sweet potato is rich in anthocyanins. Theoretically, anthocyanin is a powerful antioxidant, which can protect the human body from a harmful substance called free radicals, and also has the function of scavenging free radicals in the human body. In addition, anthocyanins can also enhance the elasticity of blood vessels, improve the circulatory system and improve the smoothness of skin, inhibit inflammation and allergies, and improve the flexibility of joints. So eating purple potato should be beneficial to human body. The statement that "purple potato causes cancer" has no scientific basis and is not credible.

Hope to adopt, thank you.
