So your doctor has told you that you're lactose intolerant. What does that mean to you? Does that mean you can't drink milk anymore? Sort of. You can supplement your diet with either changing your milk to a lactated milk, so the enzymes are added to the milk, or you can take lactate pills if you want to have milk or dairy products, such as ice cream or yogurt.
There are other options that you can do, such as changing to other forms of milk products, such as almond milk, rice milk, or hemp milk. So you can still have your cereal and still have the milk, but just not cow's milk.
People who are lactose intolerant may be able to tolerate some milk but not a lot of milk. Usually, the cutoff is about a cup. Again, it's about the quantity of milk that you're taking. Now, people who are lactose intolerant may be able to take yogurt or cheese, and that's because the milk protein has actually been predigested by fermentation. So even though you're lactose intolerant, you may be able to tolerate yogurt and cheese.
