1. Slow down aging

Blueberries, like other fruits and vegetables, are rich in antioxidants, which help to eliminate excessive free radicals in the blood, reduce the oxidative stress of cell membranes and DNA, and also slow down the aging of the human body and keep it young.

Step 2 help prevent cancer

Studies have found that blueberries are rich in substances that help fight cancer and help slow down the growth of tumors. In addition, rich antioxidants can prevent or delay the occurrence of cancer.

Step 3 improve memory

Researchers at Tufts University in the United States found that after aging mice ate blueberry extract, their sense of balance, coordination and short-term memory were improved, because anthocyanins in blueberries helped protect the brain nerves.

4. Prevention of bladder infection

Studies at Rutgers University in the United States show that blueberries can prevent bacteria from adhering to the urethral wall, thus improving urethral health and reducing the risk of bladder infection.

5. Reduce the risk of heart disease

Researchers at the University of California, Davis pointed out that blueberries can reduce the accumulation of bad cholesterol in blood vessels and reduce the chances of stroke and cardiovascular disease. Experts from the U.S. Department of Agriculture also said that blueberries are rich in substances that help fight heart disease and obesity.

Step 6 promote vision

The study found that when Israeli pilots regularly took blueberries, their night vision improved significantly. Researchers believe that this is because blueberries can increase the elasticity of microvessels around the eyes.

Proper fiber can promote intestinal health, and blueberry is a good choice to supplement dietary fiber. Eating a handful of blueberries every day can increase a lot of fiber intake.

8. Improve health during pregnancy

Blueberries are rich in nutrients, such as vitamin C, calcium, magnesium and folic acid. Among them, folic acid is good for fetal development; Magnesium helps to control blood pressure and prevent preeclampsia (toxemia of pregnancy). The dietary fiber of blueberries can also reduce the common constipation problems during pregnancy.

9. Alleviate diarrhea

Swedes will use dried blueberries to improve children's diarrhea, because anthocyanins in blueberries may have a soothing effect on diarrhea caused by Escherichia coli. However, if you have symptoms of diarrhea, it is more reassuring to seek medical treatment as soon as possible.
