For this reason, their glycemic index values are assumed to fall in the low category.Įating egg white or yolk alone should not have much effect on your blood glucose levels (3). Other vitamins that yolk is higher in include vitamins B1, B2, B5, B6, B12, and the folate form of vitamin B9.īoth egg white and yolk entirely lack vitamin C.īoth egg white and yolk contain so few carbohydrates that measuring the glycemic index would be exceedingly difficult.

The reason for this difference is that these vitamins are all fat-soluble and cannot exist in the fat-free environment of egg whites. These are vitamin A, vitamin E, vitamin D, and vitamin K. Egg white contains more vitamin B3.įour vitamins can be found in the yolk that are completely absent in egg whites. VitaminsĮgg yolk is much richer in all vitamins except for one. However, both egg white and yolk do not contain fiber and are very low in sugars. Yolk also contains higher amounts of carbohydrates. This fat is partially responsible for many health effects and physicochemical properties of egg yolk, including the yellow color. One of the most important fats found in yolk is called lecithin. We will discuss the effects of this substance on our cardiovascular health in the “Health Impact” section. The predominant fat type in egg yolk is monounsaturated fat, closely followed by saturated fat, leaving polyunsaturated fatty acids in the last place.Įgg yolk also contains large amounts of cholesterol. The yolk has rich fat content, while egg white contains only a negligible amount of fats. Yolk protein is a little richer in most of these amino acids. The protein found in yolk and egg white is highly nutritious, containing large amounts of all essential amino acids. The yolk provides 5g more protein per 100g serving compared to egg white. That being said, the egg yolk is richer in protein, being denser in nutrients overall. Egg white is commonly referred to as albumen due to its main protein. ProteinĮgg white is a rare food that consists almost entirely of protein and water.

One serving size of yolk contains 55 calories.Įgg white has much fewer calories, with 52 calories in a hundred grams. However, the yolk is usually not consumed in those amounts. CaloriesĮgg yolk alone is a very high-calorie food, containing 322 calories per 100g. One average size of egg white is considered to be 33g, while an egg yolk’s serving size is equal to 17g. We know that yolk and egg white are both highly nutritious, but which one provides more macronutrients, minerals, and vitamins? Macronutrients and CaloriesĮgg yolk is considerably denser in nutrients, containing only 52% water, whereas egg white consists of 88% water. Of this, egg white accounts for about 67% of the liquid weight, whereas yolk makes up the other 33% (2). The USDA has divided egg sizes into five groups (1). Naturally, different sizes of eggs contain different amounts of the same nutrients. Interestingly, egg whites have been used not only in the kitchen but also as a binding agent in photography, bookbinding, and wine-making, while yolk has been used in painting and microbiology. Egg white is often used to add airy texture and foam to a dish, while yolk can act as an emulsifier.Įgg white is often separated from the yolk to make meringue, macaroon, or egg white omelets.Įgg yolk can also be used on its own to make mayonnaise, custard, and hollandaise sauce. Taste and Useīecause of the nutritional differences, yolk tastes richer than egg white. Egg white is also often called albumen, based on the predominant protein found in it. Egg whites, on the other hand, primarily play a protective role for the embryo, being situated between the embryo and the hard eggshell while also providing additional nutrition. In this article, we will dive into their specific differences or similarities and see how they affect our health.Įgg yolk functions as the primary source of nutrients for the chicken embryo. Because of this, they have very different nutritional profiles.
