Summary
This trial will study how eating blueberries rich in flavonoids for 12 weeks, along with or without moderate exercise, can improve cognitive function in older adults experiencing age-related cognitive changes. The researchers
Who is the study for?
This trial is for healthy, non-smoking individuals aged 65-85 with mild cognitive decline. Participants must be physically inactive, willing to exercise (walking/stretching), avoid blueberries outside the study, and not use drugs affecting cognition. They can't have uncontrolled chronic conditions or a dementia diagnosis.
What is being tested?
The NIH study tests if eating flavonoid-rich blueberries combined with regular moderate exercise improves cognitive function in older adults experiencing age-related cognitive changes. It explores how diet and physical activity might influence gut health and cognition.
What are the potential side effects?
Potential side effects may include digestive discomfort from increased fiber intake due to blueberries and muscle soreness or fatigue from new physical activities like walking or stretching.
