Blueberries are rich in anthocyanins. The research shows that:
1. Common staple foods containing anthocyanins are: purple sweet potato, black rice, purple corn, sorghum, sweet potato and so on.
2. Common vegetables containing anthocyanins are: purple cabbage, eggplant, perilla, carrot, beet and so on.
3. Anthocyanin mainly exists in the flowers and fruits of food. Blueberries, blackberries, Lycium barbarum, blackcurrants, Lycium barbarum, cranberries, mulberries, Lonicera edulis, raspberries and other fruits all contain anthocyanin, and the amount is still very high.
At present, the functions of anthocyanins are known as follows:
1. Antioxidant
Anthocyanin is a strong antioxidant for human body, which can gradually prevent and alleviate human aging. Many antioxidant biochemical activities of blueberries can be compared with L-vitamin C. The antioxidant activity of anthocyanins extracted from natural blueberries can even be 5 times higher than that of vitamin E and 2 times higher than that of vitamin C.
2. Protecting eyesight
Anthocyanins can promote the regeneration of rhodopsin in retinal cells, prevent myopia and improve eyesight.
eye-pleasing eyesight nutrient, which is specially developed for children, is rich in anthocyanins and has a good effect on protecting children's eyesight.
3. Repair the skin
Anthocyanins make the skin smooth and elastic by inhibiting elastase and collagenase, and prevent skin damage caused by excessive sun exposure from both inside and outside.
4. Anti-cancer
Anthocyanin can effectively remove free radicals from human body, and long-term oral administration of proper amount of anthocyanin can play a role in preventing cancer.
5. Radiation protection
Anthocyanins also have the function of radiation protection. The color of anthocyanins will change due to different PH values. Most anthocyanins have good light, heat and PH stability. For white-collar workers or people who have been exposed to sunlight and electric radiation for a long time, the effect of anthocyanins is indispensable.
6, improve sleep
Anthocyanosides have the function of going deep into cells to protect the cell membrane from free radical oxidation, have strong anti-oxidation and anti-allergic functions, can cross the blood-brain barrier, can protect the brain from oxidation, can stabilize the brain tissue function and protect the brain from harmful chemicals and toxins. This effect proves why people take anthocyanins.
