A question repeated at every gathering: "how many eggs am I allowed?" The honest answer is more complex than a number — but more reassuring than it used to be.
The shift in guidelines
The 2015–2020 Dietary Guidelines for Americans recommended eggs as part of a healthy diet and abolished the 300 mg/day dietary cholesterol limit that had stood since 1968[1]. This was based on major meta-analyses of observational studies finding no significant association between egg consumption — up to one a day — and cardiovascular disease or coronary heart disease risk[1].

But newer evidence conflicts — and we'll say so plainly
- Against high intake: a meta-analysis found each additional daily egg was associated with a 7% higher all-cause mortality risk and 13% higher cancer mortality — but no association with cardiovascular mortality[2].
- In favour: recent meta-analyses of cohort studies found no significantly increased risk of coronary heart disease or stroke with higher dietary cholesterol or egg intake[3].
- And a striking geographic difference: an updated analysis found a significant positive association in US cohorts, a marginal one in European cohorts, and no association in Asian cohorts[4].
How confident can we be?
An updated umbrella review of systematic reviews and meta-analyses concluded that evidence on egg consumption is of critically low strength, and no sufficient-quality evidence exists to discourage eating eggs[5].
What to take away practically
- Eggs are not the enemy: a cheap, complete, highly satiating protein (the satiety index) and one of the best protein sources available (your numbers).
- Moderation is sensible: one to two eggs a day within a balanced diet is a conservative and reasonable position given conflicting evidence.
- What they're cooked in matters more: two boiled eggs are one thing; two eggs in heavy oil with sausages are another entirely.
- If you have high cholesterol or heart disease: that is a decision with your doctor, not with an article.
🥚 An honest bottom line: Science hasn't fully settled this — but the old fear of eggs is no longer justified by current evidence. Eat them in moderation and focus on your overall diet rather than a single item.
