Among them, selenium, known as the "anti-cancer king", is easily absorbed by the human body, and can also be retained in the serum to enhance the body's immunity, eliminate free radicals in the body, inhibit the growth of cancer cells, and prevent the occurrence of cancer. Anthocyanin is the most direct, effective and safe free radical scavenger found by the scientific community to prevent and cure diseases and maintain human health. Its ability of scavenging free radicals is 20 times that of vitamin C and 50 times that of vitamin E. it can prevent and treat more than 100 kinds of diseases.

Anthocyanins are a large group of substances widely found in all dark red, purple or blue fruits and vegetables, such as grapes, blackberries, figs, cherries, eggplant, purple sweet potatoes, blueberries, red berries, strawberries, mulberries, Hawthorn peel, perilla, black (red) rice and other plant tissues.

In recent years, many theories advocate eating "dark" foods, such as purple potatoes, purple kale, black rice and good-looking fruits such as blueberries and blackberries, which are associated with varying levels of anthocyanins.

In fact, a balanced diet and the pursuit of a rich diet is always the principle of a healthy diet. The public should not think that a certain kind of food has a health effect, just blindly eat this kind of food to achieve the effect of disease treatment and prevention, food is food, each has its own advantages and advantages, all contain a variety of nutrients that the human body needs. In addition, no matter what kind of potatoes, eating more will flatulence and acid regurgitation.
