Promising observational studies have shown correlations between egg consumption and better cognitive outcomes:
-
A 2019 Finnish study found that men who ate about four eggs per week showed no increased dementia risk and some had better cognitive performance.
-
Research in Frontiers in Nutrition (2022) linked regular egg intake in older adults to higher scores on memory and processing speed tests.
However, it’s crucial to understand the limits: These studies show a correlation, not cause and effect. They suggest that egg consumption can be part of a healthy pattern, not that eggs are a magic bullet.
Frequently Asked Questions (FAQ)
✅ How many eggs should I eat?
For most healthy adults, 1-2 eggs per day is generally safe and beneficial. Up to 6-7 eggs per week fits well within heart-healthy dietary patterns. If you have diabetes or existing heart conditions, consult your doctor for personalized advice.
❌ Do eggs raise cholesterol?
This is an outdated concern for most people. Current research shows that for the majority, dietary cholesterol from eggs has a very small effect on blood cholesterol compared to the far greater impact of saturated and trans fats.
❌ Should I eat the yolk?
Yes! The yolk is where the majority of the brain-supporting nutrients—like choline, lutein, and zeaxanthin—are found. Skipping it means missing out on the key benefits.
