Who is most suseptable to milk allergies and intollerances?

1. These are 2 different conditions. 2. By 'who' do you mean male vs female? Kids vs adults? Mexican vs asian? I can only answer #1. Milk allergies are because you are allergic to milk protiens, this is dangerous if you get rashes, swelling, trouble breathing, etc. It requires the care of an allergist to help you with an appropriate diet. Milk intolerance refers to the lactate intolerance and the bodies inability to break down the lactose which causes cramps, diareah, nausea and gas. This passes after a few hours but can easily be prevented with an over the counter lactate pill taken right when you are about to have ice cream, pizza, casadias,etc. As for #2, if there is a family history of allergires, then it means that imune ststems are not at 100% if you will, and any allergiy is possible, be it seasonal, dust or dairy.
