The selenium content is higher in food.  Purple sweet potato contains a large number of special efficacy, high medicinal value of anthocyanins. According to the 《studies of health》, French scientists Dr Musqueam le found that anthocyanins are natural potent free radical scavenger, their ability of scavenging free radicals is 20 times of vitamin C, vitamin E 50 times, anthocyanins have small molecular structure, can pass through blood-brain barrier free radicals is the only protect the brain cells of material, at the same time can reduce antibiotic some harm to the body, Purple sweet potato will become one of the main raw materials of anthocyanins. Experiments by scientists around the world have proved that anthocyanins have preventive and therapeutic effects on more than 100 diseases, and anthocyanins are known as the seventh essential nutrient after water, protein, fat, carbohydrates, vitamins and minerals. Anthocyanins have the following benefits:  

1. Helps prevent a variety of free radical related diseases, including cancer, heart disease, premature aging and arthritis;  

2. Reduce the incidence of heart disease and stroke by preventing the stress response and platelet aggregation caused by smoking;  

3. Enhance the immune system's ability to fight carcinogens;  

4. Reduce the number and duration of colds;  

5. It has the function of anti-mutation to reduce the formation of carcinogenic factors;

14. It acts as a barrier to protect brain cells from the formation of amyloid beta protein, glutamate toxicity and free radical attack, thereby preventing Alzheimer's disease;

16. Anthocyanins also have the effect of radiation resistance, and the color of anthocyanins will change with different pH values. Most anthocyanins have good stability in light, heat and pH values. For white-collar or long-term in the sun, electric radiation environment of the crowd, the effect of anthocyanin is indispensable.
