Smashed avocado on toast remains one of the most popular breakfasts around, but jumping on the trend may help you later in life.
Research has found that avocados could boost cognitive function.
Two new studies by the University of Illinois have revealed that a compound in the savoury fruit – lutein – improved brain activity.
Lutein is also present in leafy vegetables – such as spinach and kale – egg yolks and carrots.
Researchers discovered that a higher intake of lutein led to greater academic achievement in young people.

In their study, published in the International Journal of Psychophysiology, scientists found that eight to ten-year-olds with higher lutein levels performed better on tasks.
It is thought that the children with more lutein needed less brain power to accurately perform.
Similarly, another study, published in the journal of Nutritional Neuroscience, showed that those with higher lutein levels did better on a test.
While the studies were conducted on children, it is likely the compound also has a beneficial effect on adults.
“It allows us to better understand the impact nutrition, and specifically lutein, has on learning, memory and even academic performance,” said Matt Kuchan, scientist at the University of Illinois.
“This work really brings to life the important role nutrition plays in helping to create strong brain connections and helping us to focus.”
Another food that could help brain function is almonds.
The popular nut was found by a study to ward off memory loss in adults.
Research, published in the British Journal of Nutrition, showed that eating them at lunch had a positive effect on keeping blood sugar levels in balance.
When blood sugar levels dip below normal, it can affect brain function.
Additionally, omega-3 fatty acids have also been linked by scientists to reduced risk of Alzheimer’s disease.
