New Research Finds Connection Between Avocados and Cognitive Health
People love avocados for their creamy texture and delicious taste, but the best part is that it’s a healthy fat that is good for your overall health. Tufts University has released results of a study linking eating avocados to helping improve cognitive brain function in older adults, news especially relevant to Hispanics who have been found to have the longest life expectancy rate in the U.S.
Published in the journal Nutrients and supported by the USDA and the Hass Avocado Board, the research tracked how 40 healthy adults ages 50 and over who ate one fresh avocado a day for six months experienced a 25% increase in lutein levels in their eyes and significantly improved working memory and problem-solving skills.
Lutein is a type of carotenoid antioxidant, or pigment, commonly found in fruits and vegetables already widely accepted to have a role in preserving eye health and now increasingly thought to have a positive impact on brain health as well. As study participants incorporated one medium avocado into their daily diet, researchers monitored gradual growth in the amount of lutein in their eyes and progressive improvement in cognition skills as measured by tests designed to evaluate memory, processing speed, and attention levels. In contrast, the control group which did not eat avocados experienced fewer improvements in cognitive health during the study period.
