Lutein which is a nutrient found in leafy greens may have a beneficial effect in slowing the rate of cognitive aging. This is important to know because the brain ages just like every other organ in the body but without a high functioning brain the rest of the body soon fails. This of course is not the only nootropic or anti-aging supplement, as there are many such as blueberry extract for instance which also is said to have a positive effect on the rate of brain aging.
