Whey

Whey is the liquid separated from milk during cheese-making. The figures here describe sweet whey used as a commercial ingredient, rather than whey protein powder. It consists mainly of water and provides carbohydrate, with smaller amounts of protein and fat. Per 100g, it contains 5.1g of carbohydrate, all of which is sugars, 1g of protein, 0.2g of fat and 55mg of calcium.

Calcium helps maintain bones and teeth and supports normal muscle function. The sugars in sweet whey are mainly lactose, the naturally occurring sugar in milk, which can cause digestive symptoms in people with lactose intolerance. Whey also contains milk proteins, which are relevant to people with a milk allergy. Full nutrient figures are in the tables below.
