Findings showed that increased levels of antioxidants lutein and zeaxanthin were associated with a reduced risk of dementia in people aged 65 and older.

Increased levels of the antioxidant, however, reduced the risk of cognitive decline in people aged 45 years and older.

However, Doctor Beydoun pointed out: “It’s important to note that the effect of these antioxidants on the risk of dementia was reduced somewhat when we took into account other factors such as education, income, and physical activity, so it’s possible that those factors may help explain the relationship between antioxidant levels and dementia.”

Higher dietary intake of vitamin C and E have historically been hailed as the best weapon against the development of brain decline.
