Green veggies and orange fruits can help stave off dementia, according to new findings from the National Institutes of Health’s National Institute on Aging. Researchers gave 7,283 people physical exams and blood tests, and then monitored them for dementia symptoms for 16 years. Those with higher levels of lutein, zeaxanthin and beta-cryptoxanthin in their blood had significantly less incidence of dementia compared to those with lower levels of these antioxidants. Lutein and zeaxanthin are found in green, leafy vegetables like spinach, kale, peas and broccoli. Beta-cryptoxanthin is found in orange fruits like papaya, oranges and persimmons.
