"if I can tolerate milk before it's pasteurized but not be able to tolerate if after the process"
Bingo! Pasteurization and homogenation change milk into an unnatural substance. It is no wonder so many have become 'lactose intolerant'. The 'Promised Land', a 'land flowing with milk and honey' does not suggest that milk is a bad thing. But that was not Pasteurized and Homogenized'. Many who are 'lactose intolerant' have found that they can enjoy raw milk, as it comes from the cow.
Pasteurization kills/changes/immobilizes a lot of friendly stuff in milk. Homogenation changes the fat into deadly particles that do nasty things to our bodies if we are foolish enough to drink it. Not all states require that milk be pasteurized, by the way. Any who live where it is legal for raw milk to be sold might want to check it out.
Raw milk keeps longer than the pasteurized stuff. In studies, raw milk causes less illness than pasteurized milk, by a wide margin. Many men with cardiovascular problems have been milk drinkers (pasteurized and homogenized).
Many states that require that milk sold be pasteurized do not require pasteurization for making cheese. This might be why some with an intolerance to milk can eat cheese without a problem. The only thing better than dairy products from fresh, raw milk is if the cows are grazed, not grain fed. Grazed cows produce butter fat that is high in omega 3's, an unsaturated fat that is good for us.
See my post #36. Maybe that's why I don't have a problem with milk but do with cheese. Hmmm?
Most Middle Easterners drank goat milk in the Bible anyway. A person allergic to cow milk usually can handle goat and it's not as mucus forming. Store milk that has been boiled and all the rest is worthless imho.
