A recent study suggests that eating eggs may help keep the brain sharp in older adults, particularly women. The research, part of the Rancho Bernardo Study in Southern California, found that women who ate more eggs experienced less decline in verbal fluency over four years, an important finding as cognitive decline becomes more common with age.
Researchers analyzed data from 890 participants and tested their cognitive function using tools like the Mini-Mental State Examination and a category fluency test. The results showed that women who ate more eggs had better verbal fluency, while men did not see the same benefits. There was also no significant impact on other areas of cognitive function, suggesting that eating eggs might help women maintain verbal memory.
As per the findings, eggs present a straightforward and cost-effective way to bolster brain health in older women. Eggs are a rich source of choline, a nutrient vital for brain function, memory, and overall cognitive health. However, it’s crucial to opt for eggs from organic, pastured sources to avoid high levels of linoleic acid (LA), a type of fat that can impair mitochondrial function. Conventional eggs, often from chickens fed a diet high in LA, may offer different health benefits. By choosing high-quality eggs, you can optimize their cognitive benefits.
