For decades, eggs have carried an undeserved reputation as a food to avoid if you’re concerned about cholesterol. The reasoning was simple: egg yolks contain cholesterol, so eating them must raise blood cholesterol. But nutrition science has since moved on along way since then! The picture today is much more balanced.

The Cholesterol in Eggs

One large egg contains about 186 mg of cholesterol, all in the yolk. In the past, dietary guidelines recommended limiting cholesterol intake to no more than 300 mg per day, leading many people to cut back on eggs or avoid them completely.

However, research over the last 20 years has shown that the relationship between dietary cholesterol and blood cholesterol is not as straightforward as once believed. For most people, eating cholesterol-rich foods like eggs does not dramatically raise blood cholesterol levels.

In short, for the majority of people, the cholesterol we eat, doesn’t massively increase the cholesterol in our blood. 

How Eggs Affect Cholesterol Levels

Eggs can raise both HDL (the so-called ‘good’ cholesterol) and LDL (the ‘bad’ cholesterol). The important point is that the overall effect is often neutral, and in many cases, eggs improve the ratio of good to bad cholesterol.

That being said, some people are ‘hyper-responders’, meaning their blood cholesterol rises more noticeably when they eat dietary cholesterol. For these individuals, moderation may be especially important. Genetics and overall lifestyle make a big difference.

Eggs as a Nutrient Powerhouse

Beyond cholesterol, eggs are packed with valuable nutrients:

• High-quality protein with all essential amino acids

• Vitamins B12, D, and folate

• Choline, important for brain and liver health

• Antioxidants lutein and zeaxanthin, which support eye health

Compared with many processed breakfast foods, eggs are a nutrient-dense, affordable, and versatile option.

The Bottom Line

For most healthy people, eggs are not bad for cholesterol and can be part of a balanced, heart-friendly diet. That old adage springs to mind – everything in moderation. Which is what we recommend at The Cholesterol Protocol.

As a general rule, up to one egg a day is generally considered safe.

What matters most is how eggs are prepared and what you eat with them. Poached or boiled eggs with wholegrain toast and vegetables are a far healthier choice than fried eggs with bacon, butter, and sausage.

Eggs are not villains — they’re a nutritious food that, when enjoyed in balance, can support a healthy lifestyle.
