Uz meso, jaja i mlijeko animalni su proizvodi koji se koriste već tisućama godina u humanoj prehrani. Može se reći kako su jaja i mlijeko dio uravnotežene prehrane. Kroz povijest nije uvijek bilo tako, neko se vrijeme jaja tretiralo kao proizvod koji može znatno narušiti zdravlje potrošača zbog visokog udjela kolesterola. Danas to više nije slučaj, jedna i druga namirnica cijene se zbog kemijskog sastava a posebno zbog udjela proteina kao glavnog makro nutrijenta u prehrani ljudi. Cilj ovog rada bio je usporediti kemijski sastav jaja i mlijeka, utvrditi koja namirnica je bogatija proteinima te ostalim najvažnijim makro nutrijentima kao što su masti i ugljikohidrati. Together with meat, eggs and milk are animal products that have been used for centuries in human nutrition. But it was not always like that, for some period of time eggs were considered to be a product that has hazardous impact on human health due to high cholesterole content. Nowdays that is not the case anymore, both products, eggs and milk are apreciated because of their chemical composition, especiatlly protein content which is one of the most important macronutrient in human nutrition. The aim of this research was to compare chemical and both nutritional content and value of eggs and milk and to establish which product is richer in protein and other most important macro nutrients, such as fat and carbohydrates.
