Do you love eggs, but are still hesitant to eat the yolk? The response is less severe than in the past: in healthy adults, systematically ruling out the yolk is not justified. It concentrates the cholesterol, yes, but also some of the nutrients from the egg. The real question is rather the frequency, the cooking and the rest of the plate.
Egg yolk concentrates cholesterol, but that’s not the whole story
According to the French Ciqual table from Anses, a hard-boiled egg provides, per 100 g, approximately 134 kcal, 13.5 g of proteins, 8.62 g of lipids and 355 mg of cholesterol. Relative to a common serving of 50 g, this represents approximately 180 mg of cholesterol. With variations depending on the size of the egg.
The yolk concentrates most of the cholesterol, which explains its reputation. But removing it also means depriving yourself of some of the egg’s micronutrients. The whole egg remains a nutritionally dense food. It is rich in protein, with a moderate amount of lipids. And it can be integrated into the alternation of protein sources.

Another essential nuance: dietary cholesterol is not the same as blood cholesterol. In many adults, the effect of moderate egg consumption on LDL cholesterol remains limited. Saturated and trans fatty acids, present in many fatty or ultra-processed products, often weigh more in the overall cardiovascular balance.
This does not mean that yellow should be consumed without taking into account the context. Two poached eggs with vegetables doesn’t have the same profile as a daily breakfast combining eggs, bacon, cold meats and butter.
The debate is therefore not only about yellow, but about what accompanies it.
Who really needs to adjust the frequency of yellows?
For an adult without known hypercholesterolemia, without cardiovascular disease, without diabetes and without high cardiovascular risk, there is no official rule in France requiring the removal of the yolk.
The available data instead support that moderate consumption, around one egg per day, is not associated with a clear increase in cardiovascular risk in healthy people.
This formulation remains deliberately cautious. A large prospective analysis and meta-analysis published in the BMJ in 2020 did not find a significant association between an increase of one egg per day and overall cardiovascular risk in American cohorts.
But this is an association, not proof of causation. These data do not prove that eggs protect the heart, nor that they are equally suitable for all profiles.
In practice, a few simple guidelines allow you to keep yellow without making it an automatic daily occurrence:
- Alternate eggs with other sources of protein, including plant-based;
- Favor simple cooking, such as hard-boiled, soft-boiled or poached eggs, if the objective is to limit added fat;
- Avoid systematically combining eggs with cold meats or a lot of butter;
- Adapt the frequency of yellows in the event of hypercholesterolemia, diabetes, a history of cardiovascular disease or lipid-lowering treatment.
On this last point, there is no single rule: the consumption of yolks must be discussed with the doctor or dietician. It will take into account the lipid profile, possible treatments and the entire diet. If you are concerned, our article on eggs and cholesterol details useful precautions.
The method of preparation also deserves to be looked at without obsession. A hard-boiled egg in a salad, a low-fat omelette or a poached egg do not have the same impact as a very high-fat recipe. To choose according to your habits, find our guide to the healthiest cooking methods for eggs.
