According to a recent study, selenium (with the highest concentrations in Brazil nuts) could increase neuron generation, and boost learning and memory in aging brain.
The reseachers investigated whether dietary selenium supplements could replicate the effects of exercise, which turned to increase the levels of a protein, essential for transporting selenium in the blood. The results showed that selenium supplementation, indeed, mimicked the effect of exercise by increasing neuron generation and reversing the cognitive decline in older mice.
The researchers were also interested whether selenium had any positive effects on the young representatives after stroke, which can affect memory and ability to learn. And in this situation selenium supplements helped restore the ability to learn and memorize.
The found role of selenium in the study might offer a new way to boost brain health in older people with some neurological issues or people who were unable to exercise due to poor health.
However, if you are healthy, you’ll get the required amounts of selenium from a well-balanced diet, full of of fruits, nuts, veggies, whole grains, dairy products, eggs, meat and/or fish.
