What is whole milk?

If you’re looking for advice on which type of milk is best to drink, the variety of information (and milk) can be overwhelming. Aside from the plant-based and alternative milk options, how do you decide between the different varieties of cow's milk? Well, by the end of this article, you’ll understand exactly what whole milk is, whole milk nutrition benefits, and how it behaves in recipes.

How Is Whole Milk Different From Other Types of Milk?

Most of the milk Americans drink comes from cows. In the US, cow’s milk is sold by fat content. The whole milk you find in stores is typically 3.25% fat, with reduced fat at 2%, and low fat at 1%.

Skim milk is sold as non-fat milk because most of its fat content has been removed. Skim typically contains no more than 0.2% fat. Many people think that skim milk contains more naturally occurring sugar than whole milk. Truthfully, there is not as much fat in skim milk so the concentration of sugar only increases slightly and is negligible.

More fat in milk contributes to a whiter appearance, creamier consistency, and provides a silkier mouthfeel.


How Is a2 Milk® Whole Different From Regular Whole Milk?

a2 Milk® Whole is different from regular whole milk because it is from cows that only produce the A2 protein. For some people, dairy may be a source of stomach discomfort but they’re not sure why. While lactose intolerance is often assumed, in some cases it may be a sensitivity to the protein type that is the issue. This means they experience some level of gastrointestinal discomfort when consuming dairy products. However, published research suggests that milk containing the A1 protein chain may be a more likely cause for this discomfort. 

You see, most milk contains a blend of A1 and A2 proteins. But cows used to only produce A2 protein. The A1 protein developed as a genetic mutation in European cows resulting in mixed herds.

That’s why a2 Milk® is derived from true A2 herds and vigorously tested to ensure consistent quality. a2 Milk® Whole functions in recipes exactly like your favorite milk brand but may be easier on the tummy.
