【英语时差8,16】蓝莓提升记忆？-下

Scientists aren’t certain. But it may have to do with the fruit’s abundance of phytochemicals–anti inflammatory substances that also act as antioxidants. In animal studies, chemicals in blueberries boosted activity in parts of the brain associated with memory. In the same studies, blueberries appeared to lower glucose¹ levels in the brain, which could help delay memory loss. The studies shouldn’t be taken to mean that blueberries will boost your memory to superhuman levels.If your memory is basically fine, blueberries won’t necessarily enhance it. But for older people on the edge of dementia, blueberry juice could ward² off the worst symptoms and help memory hang on.
