Are Eggs Bad for Cholesterol?
The cholesterol you eat is not the cholesterol in your blood.
This is the central point that modern nutrition took decades to accept.
Your liver produces approximately 75 to 80% of the cholesterol circulating in your blood. The rest comes from food. But here is what researchers established: when you consume more dietary cholesterol, your liver produces less. When you consume less, your liver compensates by producing more.
This regulatory mechanism — called cholesterol homeostasis — means that for the vast majority of people, eating eggs does not significantly raise blood LDL.
What the most recent research shows.
The first major shift came in 2015, when U.S. nutritional authorities removed the 300mg/day dietary cholesterol limit from official recommendations — acknowledging that the evidence no longer justified a restriction that had stood for decades on poorly supported consensus.
Since then, studies have consistently pointed in the same direction.
The Framingham Offspring Study — one of the longest-running and most rigorous cardiovascular cohort studies in the world, following thousands of participants across multiple decades — found that consuming five or more eggs per week was not associated with any deterioration in lipid profile. In men, higher egg consumption was actually associated with slightly lower LDL and total cholesterol.

A randomized controlled crossover study from Purdue University demonstrated that dietary cholesterol from whole eggs was not well absorbed and did not acutely affect plasma total cholesterol in men or women.

A more recent study published in The American Journal of Clinical Nutrition in 2025 tested three different diets on 48 adults with elevated LDL. Increases in LDL were significantly related to saturated fat intake — not to cholesterol from eggs.

So what actually disrupts LDL?
Three dietary factors have documented, robust influence on raising LDL:
1. Saturated fats
Saturated fats — found in butter, processed meats, fatty cuts of meat, cheese, and tropical oils — reduce the activity of LDL receptors in the liver. These receptors are responsible for clearing LDL from the blood. When they function less efficiently, LDL accumulates.
2. Trans fatty acids
Industrial trans fats — found in hydrogenated margarines, ultra-processed foods, and some industrial baked goods — simultaneously raise LDL and lower HDL. This is the most unfavourable combination for cardiovascular risk.
A study published in Cell Metabolism in November 2024 mapped for the first time the precise molecular mechanisms by which trans fats activate liver cholesterol production via the SREBP2 pathway.
3. Refined sugars and high glycaemic index carbohydrates
When you consume excess sugar, your liver converts it into triglycerides and produces more LDL — particularly small, dense LDL particles, considered the most atherogenic. Simultaneously, HDL decreases.
The important nuance: hyper-responders
For approximately 25 to 30% of the population, dietary cholesterol has a more pronounced impact on blood LDL. These individuals — called hyper-responders — often carry a genetic variant of the ApoE gene (notably ApoE4) that reduces the efficiency of the liver's regulatory mechanism.
If your LDL remains chronically elevated despite a reasonable diet, testing your ApoE profile may be informative. This changes the individual response to dietary cholesterol.
Are eggs bad for people with high LDL?
For most people: no.
Current evidence shows that for the majority of adults — including those with moderately elevated LDL — consuming one to two eggs per day does not worsen the lipid profile in any clinically meaningful way.
What does worsen the lipid profile is often what accompanies eggs: bacon, processed meats, large amounts of butter, industrial white bread. The problem is not the egg — it is the dietary context surrounding it.
The most scientifically defensible recommendation in 2025: do not demonise eggs, but monitor saturated fats, eliminate trans fats, and limit refined sugars. These are the three levers that actually move your LDL.
The omega-3 connection
A less discussed angle: omega-3 fatty acids — particularly plant-based ALA — contribute to the maintenance of normal blood cholesterol levels. This claim is validated by the European Food Safety Authority (EFSA, EU Regulation 432/2012).
Polyunsaturated omega-3 fatty acids, when they replace saturated fats in the diet, help improve the LDL/HDL ratio — the true marker of lipid risk, beyond the simple LDL number.
This is the principle behind Dafee's Daily-Feed — one tablespoon of sacha inchi oil per day, one of the most concentrated plant source of ALA omega-3 known.
