Best Antioxidants to Prevent Age-Related Dementia Identified?
Higher levels of specific carotenoid antioxidants in blood may help guard against age-related dementia, new research suggests. Investigators found that individuals with the highest serum levels of lutein+zeaxanthin and beta-cryptoxanthin at baseline were less likely to have dementia decades later than their peers with lower levels of these antioxidants. Lutein and zeaxanthin are found in green leafy vegetables such as kale, spinach, broccoli and peas. Beta-cryptoxanthin is found in fruits such as oranges, papaya, tangerines, and persimmons.

The researchers analyzed data from 7283 participants in the Third National Health and Nutrition Examination Survey (NHANES III) who were at least 45 years old at baseline and followed for an average of 16-17 years. They found serum levels of lutein+zeaxanthin were associated with reduced risk of all-cause dementia among people aged 65 and older in models adjusted for lifestyle.
