Unhomogenized milk is perfectly fine to consume. In fact, some people like it because when the cream separates from the milk, they can skim it off and use it for other things, like coffee or cereal, and the milk that remains is considerably less fatty. However, because homogenization reduces the size of the fat particles, it also decreases the amount of time it takes for bacteria to grow if you weren't going to cook with the milk right away. If you are allergic to dairy products, you should know that most brands of unhomogenized milk contain some type of milk protein, which means that they would not be suitable for people with allergies to this product. However, since 1994, when the term "dairy-free" was first used by the non-profit organization The Dairy Free Company, many brands have been making almond and soy alternatives to regular milk. These products are just as nutritious as traditional cow's milk and can be a good alternative for those who are unable to eat dairy products due to an allergy or another reason. The key thing is that if you have an allergy, then you should only drink unpasteurized milk from cows that aren't treated with hormones or antibiotics.
