"The takeaway is that a healthy diet rich in antioxidants from dark leafy greens and orange-pigmented fruits with or without antioxidant supplements may reduce the risk of developing dementia

"But the only way to prove the connection between antioxidants and brain health is with a long-term, randomized clinical trial to see.

For this new research, study author May Beydoun of the NIA, in Baltimore, and colleagues studied nearly 7,300 people, aged 45 to 90,

The individuals were divided into three groups, depending on the level of antioxidants in their blood, and followed for an average of 16 years and as many as 26 years.
