Egg Yolks Or Eggs

Eggs are the oval reproductive bodies laid by female birds, most commonly chickens, and are a common food source. Egg yolks are the yellow, nutrient-rich center of an egg. They are used whole, separated, or in dried and liquid forms in many food products.

Eggs and egg yolks serve multiple functions in food manufacturing, including emulsifying (binding oil and water), binding ingredients, leavening (helping baked goods rise), adding color, and contributing flavor. They are frequently found in noodles, pasta, baked goods, sauces, and custards.

Eggs are recognized by the FDA as a nutritious whole food, providing protein, vitamins, and minerals. Historically, there were concerns about the cholesterol in egg yolks, but current dietary guidelines, such as the 2025-2030 Dietary Guidelines for Americans, do not specify a limit for dietary cholesterol. Research suggests that dietary cholesterol has a smaller effect on blood cholesterol levels than saturated and trans fats. As a whole food, eggs are not evaluated by bodies like JECFA or EFSA as food additives, and thus no acceptable daily intake (ADI) has been set.
