You may not be aware of it but most of the time, we eat or drink something with the notion that it does not contain even a small amount of lactose. Little did you know that there is lactose content on that meal when you are already suffering from the excruciating pain brought by lactose intolerance. The lesson is here is that you need to be aware of the foods to avoid in order to save yourself from the trouble brought by lactose intolerance. Your basic lactose intolerance diet should be filled with 100% lactose-free milk. It can also be soy milk or rice milk. On the other hand, you should stay away from instant hot chocolate, sweetened condensed milk, evaporated milk, cocoa mixes, buttermilk, whole milk, skim milk, and cheese. If you prepare vegetables for your diet, do away with buttered or creamed vegetables and those with tomato sauce or spaghetti sauce with cheese.
