Eggs Not Major Contributor to Blood Cholesterol, Nutritionists Explain

Recent nutrition research shows that eggs are not the primary driver of high blood cholesterol. A medium egg contains about 180‑220 mg of cholesterol, mostly in the yolk, but most cholesterol in the body is produced by the liver, with dietary intake accounting for only a small fraction.

The body self‑regulates: when dietary cholesterol rises, the liver reduces its own synthesis to maintain balance. Consequently, many current dietary guidelines no longer label eggs as a food to avoid entirely. The 2022 Chinese Dietary Guidelines removed the previous 300 mg per‑day cholesterol limit and state that healthy adults can safely consume roughly one egg daily as part of a balanced diet.

For individuals with normal lipid levels, one egg per day is considered acceptable. People with elevated blood lipids or cardiovascular disease should follow personalized advice from doctors or nutrition experts. Health professionals advise focusing more on limiting animal fats, fried foods, sweets, and trans‑fat‑containing products, which have a stronger impact on raising harmful LDL cholesterol.
