Two of those most prevalent in modern diets — lutein and zeaxanthin — have been shown by research to improve eye health as well as cognitive functioning in older adults.<\/p>\n To date, though, the neural mechanisms behind these improvements have remained elusive to research, author Cutter Lindbergh stated.<\/p>\n “If you can show that in fact there’s a real mechanism behind this, then you could potentially use these nutritional supplements or changes in diet, and you could easily intervene and potentially improve cognition in older adults<\/a>,” stated L Stephen Miller, a professor of psychology and corresponding author of the study.<\/p>\n
