How to Buy Cheese - as part of the expert series by GeoBeats. First thing you want to look at when you are looking at a store-bought cheese is what type of milk is used. There are three main options: there are cow's milk, sheep's milk, and goat's milk. For those that are lactose intolerant, if you go with a sheep's milk or a goat's milk cheese, you will be able to tolerate it much more readily because the casein content in those two milks is much more readily digested by those that are lactose intolerant. The next thing that you must look at is on the back they are always required to let you know if the cheese is made in a plant that processes any high allergen. For example, this cheese is made in a factory that processes nuts, so if you have a nut allergy, then you must make very sure to that look at those allergen warnings. Then you just want to make sure that there is nothing in there that you do not know what it is. If there is an ingredient you cannot pronounce, it is usually not a good idea to eat it. After that, the next thing you want to try and do is see if you can figure out where the cheese is made. If you know anything about that region at all, then you will know the flavors that are inherently going to be in that cheese. You have to remember that it comes from an animal. So whatever the animal is eating in that region, those notes are going to be in the cheese itself. So those are a couple of things that you want to look at when you are purchasing a cheese in a store.
