Its fruit is rich in nutrients, especially anthocyanins.

How to choose blueberries:
When selecting blueberries, it depends on whether their fruits are uniform and full. Then there will be a layer of white frost on its skin, which is a protective layer formed by the blueberry itself in the process of growth. The more complete the white frost is, the better the quality of the blueberry.
If blueberries smell rotten, don't buy them no matter how cheap they are. It's not only a waste of money, but also bad to eat. Fresh blueberries smell faint. Such blueberries are fresh and taste better.
