The Nurses’ Health Study...reported slower cognitive decline among older women who consumed strawberries more than two times per week when compared to those consuming less than once a week [17]. In the present analysis, we investigated the association between strawberry consumption and the risk of Alzheimer’s dementia in a community cohort of older adults...
The analytical sample of 925 participants was on average 81 (±7.2) years of age, 75% female, 98% White, had a mean educational level of 15 (±3) years, and 21.5% had an APOE-e4 allele. A total of 245 participants developed Alzheimer’s dementia over the mean follow-up of 6.7 (±3.6) years. Strawberry intake ranged from 0 to 2 servings/week (mean intake of the population: 0.64 servings/week)...
The baseline characteristics of participants consuming strawberries more than once a week were similar
to those consuming strawberries rarely or a few times/month (Table 1). Strawberry consumption was
weakly correlated with the consumption of other healthy foods, including other fruits, leafy green
vegetables, seafood, beans/legumes, olive oil, and nuts...
And here's the results:

We also assessed any confounding by total vitamin E intake and found no difference in the association (Table 2). Overall, participants consuming one or more servings of strawberries per week had a 34% lower risk of developing Alzheimer’s dementia when compared to those consuming none or less than once per month
