According to a latest study, lutein-rich foods like spinach and avocado not only give you your required dose of vitamins and proteins, but is also good for your overall cognitive skills.
Lutein is a nutrient that the body cannot make on its own hence one needs to get them through foods containing lutein. Lutein is found in high quantities in green leafy vegetables like spinach, avocado, kale and yellow carrots, as well as eggs.
A recent study published in the journal - Frontiers in Aging Neuroscience, analysed 60 adults aged 25 to 45, and found that middle-aged participants with higher levels of lutein had neural responses which were found to be more on par with yunger individuals than with their peers.
Further the researchers from the University of Illinois at Urbana-Champaign said that loading up on these lutein rich foods can help boost overall cognitive abilities in middle-aged individuals.
"As people get older, they experience typical decline. However, the research has shown that this process can start earlier than expected. You can even start to see some differences in the 30s," said the first author of the study Anne Walk.
Apart from the brain, the researchers measured lutein in the participants' eyes by making them look into a scope and respond to a flickering light. Then, using electrodes on the scalp, they measured neural activity in the brain while the participants performed cognitive tasks.
