Blueberries help older people improve their memory

US and Canadian researchers reported on the 20th that eating blueberries with continuous anthocyanins can help older people improve their memory.

  Researchers at the US Department of Agriculture, the University of Cincinnati, and the Canadian Department of Agriculture conducted a 12-week study of seniors who were expected to be over 70 years of age and had a slight decline in memory.

One group of elderly people had two to two cups of half-blueberry juice twice a day, and the other group was called a placebo drink.

After the study, the performance of the elderly who allowed blueberry juice in the learning and memory tests was significantly improved, but almost unchanged.

  Robert Krikorian, an associate professor at the University of Cincinnati, who led the study, said previous animal studies have shown that eating more blueberries can boost the memory of older animals, but few have studied the effects of eating more blueberries on human memory.

  The new study suggests that eating more blueberries may slow down neurodegeneration.

Researchers say that blueberry free radical polyphenols, anthocyanins, are usually a free radical antioxidant that protects against free radical damage in the body, enhances signal transmission in the brain, and enhances blood vessel elasticity.It inhibits arthritis and allergies, so eating more blueberries is good for the elderly.

The research has been published online in the Journal of Agricultural Chemistry and Food Chemistry published by the American Chemical Society.
