Experts have warned against diets high in cholesterol for years and have suggested, for example, limiting egg yolk intake. The previous Dietary Guidelines for Americans* stated that Americans eat too much cholesterol and that high-cholesterol foods like eggs should be limited. Preliminary reports, however, indicate that the 2015 guidelines may no longer consider cholesterol as a nutrient of concern for overconsumption.
New research suggests that dietary cholesterol intake may not significantly increase blood cholesterol levels or increase the risk of heart disease in healthy adults. Saturated fat and trans fat in the diet are of greater concern for keeping blood cholesterol levels down than the actual cholesterol content of food. However, it is still recommended that we consume limited amounts of foods high in saturated fat or trans fat (e.g., butter, margarine, fats in meat, and high-fat dairy).
Eggs are an inexpensive protein food that is relatively low in total fat and saturated fat and rich in vitamins and minerals. Therefore, eggs can be part of a healthy diet. It is still recommended to eat them in moderation and prepare them with low-fat cooking methods like boiling or poaching.
*The Dietary Guidelines for Americans are updated every five years by the U.S. Department of Agriculture and the Department of Health and Human Services. They provide dietary and physical activity recommendations for Americans ages two years and over to reduce risk of chronic disease and promote overall health.
