Milk is a source of calcium, vitamin D and protein that the body needs to nourish the muscles and cells. Many people drink different types of milk due to health restrictions such as high cholesterol, obesity and heart disease. The food industry labels the different types of milk by colour to make it easy to recognise. According to the Oklahoma Cooperative Extension Service, "One cup of milk provides 1/3 the recommended daily allowance of calcium and phosphorus." Milk supplies riboflavin and vitamin D which helps tissue development. The protein found in milk is one of the highest quality proteins offered by any other food source.
The red label and cap on a milk jug indicates that the milk is whole milk and not reduced or fat-free. Whole milk that is pasteurised and homogenised still retains the milk fat, but has been heated to destroy any naturally occurring bacteria that would make you sick. Red is used by several dairies so it is easily recognised as whole milk.
Two per cent milk is recognised by the blue cap and label. This is the type of milk that is recommended for use in school systems because it is lower in fat. This labelling means the milk contains less fat, but is not low fat. Depending on which dairy produces the milk, the cap colours may vary between light and dark blue. For example: Borden and Amish Country Farms have a light blue cap, while Dari Gold and Dean's are dark blue.
The green colour indicates the milk is one per cent or low fat. Amish Country Farms, Clover Organic, Farmer's Creamery and Albertson's brand milk have the green label, however, if you by your milk at Trader Joe's their label is pink.
Skim or Nonfat Milk has the purple cap and means that this type of milk contains little to no fat.
Chocolate milk is made from either low fat or whole milk to which chocolate and sugar are added. In 2005, the New York City Department of Education began replacing whole milk with lower fat versions, and chose fat-free chocolate milk in place of regular chocolate milk. According to ABC News, the New York City state schools switched to low fat milk to decrease the student's overall fat and calorie intake.
