The study systematically reviewed randomized controlled trials examining the impact of berry-based foods and supplements on cognitive function in older adults. Results suggest that such interventions, rich in polyphenols and antioxidants, may improve memory, executive function, psychomotor performance, and brain perfusion. These findings highlight berries' potential role in mitigating age-related cognitive decline, primarily through antioxidant and anti-inflammatory mechanisms. While promising, limitations like small sample sizes and varied methodologies require cautious interpretation.
Incorporating berries (like blueberries or strawberries) into daily diets may support cognitive health, especially in older adults. Aim for fresh, frozen, or minimally processed forms without added sugars. However, the evidence is still emerging; effects might vary based on individual health status and dosage. Further research is necessary to establish optimal intake and long-term safety.
