Milk composition. Milk provides essential nutrients and is an important source of dietary energy, high-quality proteins and fats. Milk can make a significant contribution to the required nutrient intakes for calcium, magnesium, selenium, riboflavin, vitamin B12 and pantothenic acid.
The composition of milk differs widely among species. Factors such as the type of protein; the proportion of protein, fat, and sugar; the levels of various vitamins and minerals; and the size of the butterfat globules, and the strength of the curd are among those that may vary. [24]
The Milk Composition section describes the chemical and physical properties and effects of pasteurization on the compounds in milk. A brief overview of the variation in milk composition is provided below as an introduction to this section.
Jun 21, 2024 · Milk is essentially an emulsion of fat and protein in water, along with dissolved sugar ( carbohydrate ), minerals, and vitamins. These constituents are present in the milk of all mammals, though their proportions differ from one species to another and within species. ( See Table.)

The composition of milk (fat, protein from varying amino acids) may differ depending on the breed and feed of the cows. Are other factors in the diet considered, such as if the participants are eating plenty of fruits and vegetables, or large amounts of processed meat or refined carbohydrates, which can confound the true health effects of milk?
