At Oriems Fit Research Digest, we bring you the latest science in a simple and practical way. Today, we’re looking at eggs and brain function—can they actually make you smarter and sharper?
For years, eggs had a bad reputation due to cholesterol concerns, but newer research is revealing their potential brain benefits. A systematic review from Monash University examined multiple studies to find out if eggs can improve memory, reaction time, and cognitive function.
Eggs & Cholesterol: A Big Misunderstanding
🔸 1960s-1980s: Eggs were blamed for increasing cholesterol and heart disease risk. People were told to eat fewer eggs.
🔸 Now: Research shows that dietary cholesterol from eggs doesn’t significantly impact blood cholesterol.
🔸 The real problem? Saturated and trans fats, not eggs, are the biggest cause of high LDL ("bad") cholesterol.
But what about eggs and brain health? Let’s explore what the research says.
Who Conducted This Research?
📌 Researchers from Monash University, La Trobe University, and Swinburne University of Technology in Australia.
📌 Presented at the 47th Annual Scientific Meeting of the Nutrition Society of Australia and New Zealand (2023).
📌 Published in the Proceedings of the Nutrition Society, a journal from Cambridge University Press.
Why Is This Study Trustworthy?
✔ Peer-reviewed: Reviewed by experts before publication.
✔ Cambridge University Press: A highly respected academic publisher.
✔ No industry funding: No bias from food companies.
What Did the Study Find?
The researchers reviewed 12 studies that examined egg consumption and brain function in healthy adults. The findings suggest that eating eggs could have positive effects on brain health, especially in memory, reaction time, and cognitive function.
🔹 Do Eggs Protect Against Cognitive Decline?
- 5 out of 12 studies found that frequent egg consumption was linked to a lower risk of cognitive decline.
- Regular egg eaters tended to maintain better memory and mental sharpness over time.
- However, 4 studies found no significant effect, showing that individual results may vary.
🔹 Do Eggs Improve Reaction Time?
- A randomized controlled trial (RCT) showed that eating 2 eggs per day improved reaction times in healthy adults after 8 weeks.
- Faster reaction times mean quicker thinking, better reflexes, and improved decision-making—a great benefit for athletes, professionals, and even gamers.
🔹 Do Eggs Improve Memory?
- Some studies found that egg eaters performed better on memory tests, suggesting that eggs may support recall ability.
- However, not all studies showed this benefit, meaning more research is needed.
Why Might Eggs Support Brain Health?
The nutrients inside eggs play a huge role in brain function.
🥚 Phospholipids (30% of egg yolk lipids) – Support neurotransmitters that help with learning and memory.
🥚 Choline (340 mg per egg) – A key nutrient that builds acetylcholine, a neurotransmitter essential for memory and focus.
🥚 DHA (25 mg per egg) – An omega-3 fatty acid that supports brain development, neuroplasticity, and reaction time.
Each of these nutrients contributes to stronger brain function, explaining why some studies show positive effects on memory and cognition.
Should You Eat More Eggs?
Eggs are a nutrient-rich food that may benefit brain function, but they aren’t a magic solution. Other factors—such as a balanced diet, exercise, and mental stimulation—also play a role in keeping your brain sharp.
Final Thoughts
Eating eggs may help with memory, cognitive function, and reaction time, but more high-quality studies are needed. If you enjoy eggs, there’s no reason to stop eating them—your brain might thank you!
