Researchers at the Virginia Tech Carilion School of Medicine discovered a link between diet and brain health. The study found that certain nutrients in common vegetables safeguard our brains from Alzheimer's disease.
Currently, 6 million Americans are affected by Alzheimer's.
Why it matters
The study found that Alzheimer's disease is associated with significantly lower levels of dietary antioxidants in the brain compared to healthy brains. This suggests that proper nutrition is crucial in preventing this debilitating condition.
“This study, for the first time, demonstrates deficits in important dietary antioxidants in Alzheimer’s brains. These results are consistent with large population studies that found the risk for Alzheimer’s disease was significantly lower in those who ate diets rich in carotenoids, or had high levels of lutein and zeaxanthin in their blood, or accumulated in their retina as macular pigment,” —C. Kathleen Dorey, PhD, lead researcher on the study and professor at the medical school
The big picture
Colorful vegetables aren't just making your plate look attractive—they're protecting your brain.
- Powerful antioxidants called carotenoids, found in everyday vegetables like kale, spinach, corn, and orange peppers, are crucial for maintaining brain health.
- These compounds are selectively accumulated by the brain, suggesting their fundamental importance in cognitive function.
Research findings
Participants following the MIND diet — higher levels of antioxidant-rich fruits, nuts, vegetables, and fish, and lower levels of meat and sweets — had reduced risk for Alzheimer’s, higher cognitive performance, and less Alzheimer’s-related brain pathology.
- 50% lower Alzheimer's risk in people with high carotenoid intake
- the study involved 1,000+ participants living in Chicago tracked in the Rush University Memory and Aging Project
- Half the normal levels of lutein, zeaxanthin, and lycopene found in Alzheimer's-affected brains
The takeaway
The message is clear: Enjoying a vegetable-rich diet today could help safeguard your future cognitive function.
"I'd be thrilled if our data motivated people to keep their brains in optimum condition with a colorful diet with abundant carotenoids and regular exercise." —C. Kathleen Dorey, PhD
