Avocado reigns supreme among other superfruits, thanks to its amazing health benefits and impressive nutrient profile. According to a recent study, consuming avocados regularly can also help overweight or obese adults improve their ability to focus.
Avocados are full of lutein, a dietary component linked to cognitive benefits. The benefits of avocado consumption have been previously studied in older adults and children.
However, no randomized controlled trials have looked at the cognitive effects of avocados in overweight or obese adults, even though at least 70 percent of the American adult population belong to that category, explained Caitlyn Edwards, a graduate student and the first author of the study.
Naiman Khan, a kinesiology and community health professor who led the study, explained that earlier research suggest overweight and obese people are at high risk of cognitive decline and dementia in old age. For the study, Khan and colleagues investigated whether dietary approaches can offer cognitive benefits, especially in midlife.
The researchers provided 12 weeks of daily meals to 84 overweight or obese adults. All the meals were identical in calories and macronutrients, but one group’s meals included a fresh avocado every day.
At the beginning and end of the study, the volunteers were told to complete three cognitive tests to measure attention and inhibition. The researchers also measured the participants’ blood and retinal lutein levels, the latter of which is associated with lutein concentration in the brain.
The results showed that the volunteers who regularly consumed avocados improved their performance on the Flanker task. This cognitive test measures attentional inhibition or a person’s ability to maintain focus on the task at hand even while being distracted.
Khan explained that the nutrients in avocados have a specific action in the brain that supports attention and focus. They might also be more beneficial for certain cognitive abilities over others, he added.
There’s also the chance that other effects could be observed in a longer study or different tests. Data from other studies have found broader effects in other populations, and the findings of this study shed light on the specific effects of avocado consumption in overweight or obese adults.
The researchers also reported that even though the volunteers who consumed avocados had higher levels of lutein at the end of the study, the changes in lutein levels were not correlated with the recorded cognitive changes.
Avocados are also full of fiber and monounsaturated fats. Edwards suggested that these other nutrients may be linked to the cognitive effects observed in the study.
