Dietary saturated fats impact benefits of daily egg consumption

Recent research published in The American Journal of Clinical Nutrition suggests that consuming two eggs per day can help reduce bad LDL cholesterol, provided it is part of a diet low in saturated fats. A 2025 study found that these benefits were observed after five weeks when participants maintained a low-saturated-fat diet. However, these results were not achieved in diets high in both cholesterol and saturated fats, regardless of egg consumption frequency.

Nutrition experts emphasize that the total composition of a meal is more critical than the number of eggs eaten. Keith Ayoob from Albert Einstein College of Medicine noted that the primary concern is not the eggs themselves, but the high-saturated-fat foods often paired with them, such as butter, bacon, or cheese.

Furthermore, medical experts like Dr. David L. Katz point out that most blood cholesterol is produced by the liver rather than being taken directly from food. Saturated fats can increase LDL levels by hindering the liver's ability to remove cholesterol from the blood and by increasing the number of circulating cholesterol particles.
