Avocados, apparently have more advantages than we think: Latest research suggests that the oily fruit can boost eye health, brain health, memory and attention span.
Study 1: The positive effects Avocados have on brain health.
A team of researchers at Tufts University’s Jean Mayer USDA Human Nutrition Research Centre on Aging, found the connection between such curative properties and the lutein content of avocadoes. Both eyes and the brain incorporate this carotenoid.
The study was conducted on a healthy group of men and women. They were asked to consume either an avocado a day or a cup of potatoes/chickpeas a day for six months. The former provided a dose of lutein of about 0.5 mg.
The results of the test showed that avocados provided this nutrient in a much larger quantity than potatoes/chickpeas.
The increase in lutein levels in the blood and eye macula of the avocado consumers had an overall increase of 25% instead of 15% like in the others.
Macular pigment density, a marker for better eye health, also showed a rise in the avocado consumers.
This is not only a biomarker for lutein levels in the brain, but also an indicator for better brain health, better memory and problem resolving skills.
“Other proposed mechanisms by which lutein is embedded in neural tissue include the modulation of functional properties of synaptic membranes, along with certain changes in the physiochemical and structural features of these membranes,” the researchers added.
Study 2: How Avocados might help ward off cognitive aging.
Another parallel research published in Frontiers in Aging Neuro-science, illustrated the powerful properties of lutein present in our favorite oily vegetable and other leafy greens that might help to prevent and delay cognitive aging.
The research done at the University of Illinois’ Urbana-Champaign, saw researchers engaging a group of sixty individuals of ages ranging from 25-45. Then their lutein levels and neural activity were tested by an attention test.
The health experts found that middle-aged participants with higher lutein levels had neural responses that were more similar to the younger volunteers compared with their counterparts with lower lutein levels. Thus demonstrating the connection between lutein levels in the brain and cognitive/brain aging.
There appears to be a certain protective property to lutein which prevents neural degeneration that is characteristic to aging.
Introducing Avocados in your diet, therefore, will boost your brain health and fight the effects of aging.
