As we get older, many of us worry about memory loss and conditions like Alzheimer’s disease. While there’s no guaranteed way to prevent dementia, new research is showing that the foods we eat can play a powerful role in supporting brain health. One food in particular is getting attention – eggs.
Eggs are packed with brain-friendly nutrients like choline, omega-3 fatty acids and lutein. These nutrients have already been linked to better memory and thinking skills. But until now, researchers weren’t sure if eating eggs could help reduce the risk of Alzheimer’s disease itself.
That changed with a recent study from the Rush Memory and Aging Project, a long-running research program that has followed thousands of older adults over many years to understand how lifestyle habits affect brain health.
What the Study Looked At
The researchers followed over 1,000 older adults, most in their 80s, asking them questions about what they ate – including how often they had eggs. They kept track of the participants for almost seven years to see who developed Alzheimer’s dementia.
Even more impressively, when participants passed away, many had agreed to donate their brains to science. This allowed researchers to look directly at the changes in the brain that are known to be signs of Alzheimer’s disease.
What They Found
People who ate more than one egg per week had a much lower risk of developing Alzheimer’s dementia – about 47% lower, compared to people who rarely ate eggs. And the brain autopsies showed the same trend. Those who regularly ate eggs had fewer signs of Alzheimer’s damage in their brains.
The scientists also discovered that one key nutrient in eggs, choline, seems to play a big part in this protective effect. Choline helps keep brain cells healthy and supports communication between them. It’s also important for memory. In fact, nearly 40% of the benefits seen in the study were linked to choline alone.
Why This Matters
We often think of brain diseases like Alzheimer’s as something we can’t do much about. But this study suggests otherwise. It shows that even simple choices, like including eggs in your diet, might help protect your brain over time.
This doesn’t mean eggs are a magic bullet or that they can prevent Alzheimer’s on their own. But as part of a healthy, balanced diet, eggs may be a valuable ally in supporting brain health as we age. Add this to other good practices like proper sleep, exercise and social engagement and you can be proactive about adding more healthy years to your life.
Final Thoughts
This study from the Rush Memory and Aging Project is another reminder that our daily choices can have a big impact on long-term health. Eggs are an easy and accessible source of brain-friendly nutrients, especially choline. Now, if only the price of eggs would come down.
