Eggs and Alzheimer’s: New Study Challenges Assumptions

A new study suggests that eating more eggs may be linked to a lower risk of dementia. But what does the research actually show?

Dr. Bret Scher breaks down the headlines, the limitations of observational nutrition research, and the surprisingly important detail hidden in the baseline data.

The people eating the fewest eggs entered the study with what many would consider “healthier” lifestyles:

👉 Lower BMI

👉 More exercise

👉 Less smoking

👉 Higher education levels

Yet they showed worse dementia outcomes than the highest egg consumers.

That doesn’t prove eggs prevent dementia. But it does challenge the long-standing narrative that eggs are harmful, especially when the bias in the study appeared to work against egg consumption from the start.

Dr. Scher also explores:

🥚 Why observational nutrition studies can be misleading

🥚 The concept of “healthy user bias”

🥚 Why dietary cholesterol and heart disease risk are not the same thing

🥚 The nutrient density of eggs, including protein, choline, and healthy fats

🥚 Why the decades-long fear of eggs may not hold up under scrutiny

This conversation is a reminder that nutrition science is often more nuanced than headlines make it seem, and why context matters when interpreting research.
