New research has revealed that strawberries, blueberries, acai berries, and other similar foods may actually help prevent mental decline with age, according to AARP.org.
This appears to be due to the fact that berries help the microglia clean the brain of biochemical debris, which are crucial to maintaining cognitive function, particularly in later years.
Molecular biologist Shibu Poulose explained that the effect of these processes diminish with age, so anything that aids microglia in their work can keep the brain sharp.
"In previous work we showed that supplementing the diets of aged mice with berry extracts improved their ability to process information," he told the news provider.
The build-up of this toxic litter can be mediated with a steady diet of berries and, consequently, older adults may have better cognitive function and memory.
There are also other mental exercises that can help maintain mental health. Fitness-For-Fifty-Plus.com recommends that brain fitness exercises are also great ways for older adults to stay mentally fit. One of the best ways to do this is to learn something new. This could be a new language, technology or game.
Crossword puzzles can also be brain fitness exercises that benefit older adults.
