3. Milkshake
If you can’t drink milk, it is also pretty certain that you will have to forego milkshakes as well.
In fact, milkshakes may have more lactose than a simple glass of milk, because they usually contain ice cream and milk, and are a double whammy. You can make a tasty alternative with soy ice cream and soy milk.
Given the number of dairy alternatives on the market, you have a choice of great flavors. Also, consider opting for a fruit smoothie instead of a milkshake, but make sure there is no hidden dairy in your smoothie.
