The risk of having Alzheimer’s dementia in older adults may be reduced by eating more strawberries, according to researchers at Rush University, Chicago.
A team led by Puja Agarwal analyzed data collected from 295 people — ages 58 to 98 and dementia-free at the start of the study — using food questionnaires and neurological evaluations as part of the Rush Memory and Aging Project between 2004 and 2018, according to a news release.
The association between frequent strawberry consumption and decreased Alzheimer’s dementia emerged and information on the link was published in the December 2019 issue of Nutrients.
Researchers said there is a potential link between disease symptoms and more oxidative stress and inflammation. Strawberries appear to have anti-oxidative and anti-inflammatory properties, possibly due to high content of flavonoids and vitamin C. Also, animal studies have shown strawberries improve neuronal function, cognition and some motor outcomes, according to the release.
Strawberry intake ranged from zero to two servings a week in the Rush study. Researcher found for every single serving increase in strawberry consumption, there was a 24 percent reduced risk of Alzheimer’s dementia.
Overall, participants eating one or more servings of strawberries per week had a 34 percent lower risk of developing Alzheimer’s dementia when compared to those consuming none or less than once per month.
