Lutein may slow down intellectual aging

Research by American scientists at the University of Illinois has just been published in Frontiers in Aging Neuroscience, citing the ability of lutein - the nutrient contained in spinach and some other dark green leafy vegetables, as well as in the left. Butter and eggs - may help slow cognitive aging.

Lutein is found in avocados, eggs, spinach and some other dark green leafy vegetables.

The team investigated over 60 people from 20 to 45 years, by measuring lutein in the eye, then attaching electrodes to the scalp to measure brain nerve activity, while participants tested the ability to pay attention. I mean. The analysis showed higher neuronal response in people with high levels of lutein.

The co-author of the study, Dr. Anne Walk, confirms: "The electrical-neurological signs of older participants with high levels of lutein are often as high as those of young people and much higher than those of the same age who have low lutein ".

The research leader, Professor Naiman Khan, said: "For a long time, we have known that green leafy vegetables, avocado and eggs are useful for physical health and this time data has added cognitive benefits." . Most of this type of research has long been focused on older people, after a period of cognitive decline.

Scientists at the University of Illinois pay attention to a group of young and middle-aged people to show that aging may take place sooner. They argue that if lutein can protect against cognitive decline, people should take lutein-rich foods right from a young age - when nutrients have maximum benefits.
