7. Cognitive Decline
It has been determined that folic acids are linked to cognitive decline in the elderly. In one study, people who consumed 800 mcg folic acids over a three-year period performed better in cognitive tests that measured processing speed, memory and word fluency than those who were given a placebo. It has been proven that taking a folic-acid supplement can also stop hearing loss among older people with high homocysteine and low folate.
Folate supplements can also prevent macular degeneration. This is the most common cause of blindness among people over 50. Folic acid has a direct connection to brain function. It can reduce memory loss, and may even help those with Alzheimer’s. All of these reasons are good enough to increase your folic-acid intake as you get older to prevent cognitive decline.
