Avacado a day may improve cognitive functions

A diet including daily avocado consumption improves the ability to focus attention in adults whose measurements of height and weight are categorised as overweight or obese, say researchers.

For the findings, researchers conducted the 12-week study of daily meals to 84 adults with overweight or obesity.

"Previous work has shown that individuals with overweight and obesity are at higher risk for cognitive decline and dementia in older age," said study author.

Avocados are high in lutein, a dietary component associated with cognitive benefits.

Though avocado consumption's benefits have been studied in older adults and children, no randomised controlled trials had studied its cognitive effects on adults with overweight or obesity. In the new study, the researchers provided 12 weeks of daily meals to 84 adults with overweight or obesity.
