Effects of fruit and vegetable intake on memory and attention: a systematic review of randomized controlled trials

This systematic review analyzed 13 randomized controlled trials to examine how fruit and vegetable consumption affects memory and attention. The results showed that regular intake, particularly over 10-12 weeks, improved memory and attention, with stronger effects observed in children and younger adults compared to older adults, who needed higher doses for similar benefits. Foods like blueberries and grapes, rich in antioxidants and polyphenols, were particularly effective. The findings highlight the cognitive benefits of dietary nutrients in fruits and vegetables, promoting brain health across age groups.

Incorporate fruits and vegetables like blueberries, grapes, and cherries into your diet to enhance memory and attention. Aim for consistent intake over weeks rather than expecting immediate effects. Older adults may need higher amounts or supplements to achieve noticeable benefits.
