Technically you will get no benefits from dairy anyway, since it naturally causes a calcium
deficiency. See
http://www.drfuhrman.com/ and Dr Oz.
Better sources of calcium that will not cause a deficiency are veggies, beans, and tofu. You don't have to cut out dairy since it can provide lean protein, but it has minimal absorbable nutrients. Other sources will be more beneficial.
