Are eggs healthy?
For most people, eggs are a nourishing whole food — modern evidence has largely cleared them of causing heart disease.
Eggs are a complete protein rich in choline, lutein, and vitamin D. Cohort studies and meta-analyses (reviews that pool results from many earlier trials) show no consistent link between moderate egg intake (up to one daily) and cardiovascular disease in most people. Individual response varies, especially in diabetes.
What is it?
The whole egg of a domestic hen, containing protein-rich white and nutrient-dense yolk.
Why it matters
An affordable, complete food unjustly demonized for decades.
Persian tradition
Persian and Mediterranean traditions cooked eggs simply — with herbs, tomato, or in kuku.
Modern scientific evidence
Meta-analyses show no clear link between moderate egg intake and CVD in general population.
Signal for slight increase in diabetic populations.
Practical daily use
- One egg most days is generally safe.
- Prefer boiled, poached, or gently fried.
Safety
- Cook thoroughly for pregnant, elderly, immunocompromised.
- People with diabetes should discuss intake with clinician.
If a symptom is new, severe, or persistent — or you are pregnant, on medication, or managing a chronic condition — please speak with a qualified clinician who knows you. Read Safety First.
