Apples Are Loaded with Nutrients That May Help Support Cognition
An apple a day keeps the doctor away, as the old saying goes. Indeed, the popular fruit has long been associated with overall good health. Apples also contain nutrients that have been shown to support healthy brain function and cognition.
Apples contain a flavonoid called quercetin, which can provide antioxidant protection, according to a 2020 research review.
In addition to quercetin, a type of polyphenol, apples contain other compounds called catechins, which are present in such brain-boosting foods as green tea, berries, and certain spices such as curry.
A 2021 research review on polyphenols and cognition in humans found an association in many studies between polyphenol consumption and certain cognitive benefits. But the authors added that further research is required to strengthen the reliability of the evidence base.
Another 2018 research review cited a study that found improved cognitive function in elderly South Asian participants who frequently consumed turmeric-containing curry, compared with those who rarely consumed the spice. The authors also pointed to additional research that found Japanese elderly adults who drank green tea also had better cognitive function than similar senior adults who were either non-tea drinkers, or coffee and black tea drinkers.
Pharmacists, as trusted health care providers, should always recommend their clients make regular visits to the doctor. But they also can feel confident recommending their clients pick up a big bag of apples as another way to stay sharp.
