Whey Protein Concentrate: A Brief Summary
By Dr. Michael Colgan
On average, high quality milk is 27 percent protein, 37 percent lactose (milk sugar), and 30 percent fat. The remaining 6 percent is calcium, other minerals, and ash.
Thus, what is called “4 percent milk” or “whole milk” is a high fat food, because the percentage determination includes the water, and milk is mainly water. Its label is largely a commercial fiction. It is not a prime food, especially when trying to increase muscle or to reduce body fat.
What is called “2 percent milk” still contains more fat and more lactose than protein. It is not a prime food either.
Skim milk has near zero fat but still contains a high amount of lactose. Skim milk powder, which some people use in cooking and as a low-fat protein source, is the worst of milk, because more than half of it is lactose.
Up to 30 percent of adults have varying degrees of allergic responses to lactose, because lactase, its digesting enzyme in the gut, declines rapidly during childhood. Humans and their pets are the only adult animals that drink milk.
