Avocado diet for obesity to improve concentration

A daily avocado diet for 12 weeks, according to a new study, can improve cognitive skills in adults. The researchers classified the measurements of height and weight of the test subjects as overweight or obese. This resulted in new randomized study results. Scientists from the University of Illinois conducted the 12-week study and published it in the International Journal of Psychophysiology.

Avocado diet for cognitive health

Previous research has shown that overweight and obese people are at higher risk of cognitive decline and dementia. For this reason, scientists are interested in whether nutritional approaches can have benefits for cognitive health. This is especially true in middle age.

Avocados contain a lot of lutein. This is a nutritional component that scientists associate with cognitive benefits. Although they have studied the benefits of such an avocado diet in older adults and children, no randomized controlled trial has examined the cognitive effects on overweight people. Many people fall into this category these days.

In the new study, the researchers provided daily meals to 84 adults who were overweight or obese for 12 weeks. These were identical in calories and macronutrients, but the food in one group contained fresh avocado every day, while the control group was not given butter pears. At the beginning and end of the study, participants completed three cognitive tests to measure attention and inhibition. In addition, the researchers measured lutein levels in the blood and retina, which is related to its concentration in the brain.

The researchers found that the avocado diet improved participants' performance in one of the cognitive tests. This is the ability to focus on the task at hand, even when distracted. However, there was no difference between the other two cognitive tests. It could be that nutrients in avocados have a specific effect in the brain. This supports the ability to do the task in particular. With certain cognitive abilities, the test subjects could be more advantageous than others.

It is also possible that other effects can be seen with a longer study or other tests. Other studies have found broader effects in other populations, so it is interesting to see a more specific benefit for this population. Another unexpected finding was that the participants who ate avocados had higher lutein levels at the end of the study, but the changes in levels did not correlate with their cognitive changes.

Avocados are also rich in fiber and monounsaturated fatty acids. It is possible that these other nutrients have played a role in the cognitive effects. Future analyzes could therefore focus on other nutrients contained in avocados.

Eat healthy avocado daily

Although this study focused on avocados, other sources of food have lutein, fiber, and unsaturated fats. These would be green leafy vegetables or eggs, for example, which would also have potential cognitive and health benefits. Above all, the study shows that small changes in diet, such as eating avocados, can have a measurable impact on cognitive performance, even if other health behaviors remain the same.
