Egg yolks raise your cholesterol, so eat only the whites.
This is the one on the list where the evidence is genuinely mixed and honest experts still disagree. What has clearly changed is the old assumption that dietary cholesterol maps straight onto blood cholesterol for everyone.

The claim, as people state it
“Egg yolks raise your cholesterol, so eat only the whites.”
What is actually known
Most of the cholesterol in your blood is made by your liver, not eaten. When dietary cholesterol rises, the liver in most people compensates by making less. That is why several national guidelines dropped their specific numeric cap on dietary cholesterol, while continuing to advise against diets high in saturated fat.
Response varies between people, and the variation is real rather than a hedge. A minority — often called hyper-responders — show a clear rise in blood lipids with dietary cholesterol. People with familial hypercholesterolaemia or diabetes appear in some analyses to be at higher risk from high egg intake, and large observational studies have landed on both sides of that question within the last decade. Anyone who tells you this is fully settled is overstating it.
What is not in dispute is where the nutrition lives. Nearly all of an egg's fat, and essentially all of its choline, vitamin D, vitamin A, vitamin B12, selenium and lutein, are in the yolk. The white is protein and water. Throwing away the yolk throws away the reason an egg is a nutritious food, as the arithmetic below shows.
Why the myth persists
Because the guidance genuinely used to say this, for decades, on the basis of a plausible mechanism. Advice that has been official is very slow to become unofficial, and "the yolk is the bad part" is easy to remember and easy to act on.
The arithmetic
One large egg is about 50 g of edible weight. From the food database that is 78 kcal, 6.3 g of protein and 5.3 g of fat.
| Eggs | kcal | Protein (g) | Fat (g) |
|---|---|---|---|
| 1 egg | 78 | 6.3 | 5.3 |
| 2 eggs | 155 | 12.6 | 10.6 |
| 3 eggs | 233 | 18.9 | 15.9 |
Nearly all of that 5.3 g of fat is in the yolk, and so is essentially all of the choline, vitamin D, vitamin A, vitamin B12, selenium and lutein. Discard the yolk and roughly 48 kcal and almost every micronutrient go into the bin, leaving about 3.2 g of protein per egg behind.
This page prints no cholesterol figure per egg. The TempoLife food database stores energy, protein, carbohydrate, fat, fibre, sugar, saturated fat and salt — it has no cholesterol column, so there is no honest number to show, and making one up to complete the table is not an option. That absence is itself the point: a claim about cholesterol should be settled with cholesterol data, and where the data is not to hand, the page says so.
Every figure in this section was computed when this page loaded, from 5 237 food rows and 31 exercise rows already in this repository. Nothing in it is stored as prose.
The honest nuance
The context around the egg usually matters more than the egg. Two eggs with spinach is a different meal from two eggs with bacon, sausage and fried bread, and observational studies of egg intake have a hard time separating those.
If you have raised cholesterol, diabetes or a family history of early heart disease, this is exactly the situation where a general web page should defer. Your clinician can look at your actual lipid panel, which is information no article has.
This page does not print a cholesterol figure per egg. The food database behind TempoLife carries energy, macronutrients, fibre, sugar, saturated fat and salt — it has no cholesterol column, so there is no honest number to show, and inventing one is not an option.
This claim is rated "it depends" because the evidence is genuinely mixed, not to avoid taking a position. Where good researchers still disagree, this page says so rather than choosing a side for you.
General information, not a diagnosis and not medical advice. Anything touching a condition you have, a medicine you take or a test result belongs with your own clinician, who has information no web page does.
Frequently asked questions
How many eggs a day is safe?
For healthy adults, an egg a day is widely regarded as fine within a varied diet. Beyond that the evidence thins out and the honest answer is that it depends on the rest of your diet and your own risk profile.
Are egg whites still useful?
Yes — they are efficient, low-energy protein. The mistake is treating the yolk as a hazard to be discarded rather than as the nutrient-dense half.
