I find that eating much cheese of any kind is not too good for my digestive system. It tastes great, mind you...but if I eat very much of it, I might as well have swallowed some slow setting cement. Thus, I have learned to eat only small amounts of cheese on occasion and very little dairy products (milk, cheese, etc).

Asians have difficulty digesting dairy products. It might be that I have a system similar to the average Asian. It's not an allergy, I just don't digest the stuff well, that's all.

(cow's) Milk is also lousy for those who sing, because it causes a buildup of mucus in the bronchials and the digestive system. Add to that the fact that commercially sold cow's milk is full of various added chemical and hormones from not very healthy animals (in many cases), and you've got a very good reason to avoid drinking the stuff at all.

What people primarily need to drink is pure water, and lots of it. Remember that stuff? ;-) It's transparent, it's found in Nature, and it makes up a great deal of your body weight, and you can't live without it for more than a few days. You used to be able to get it everywhere for free not too long ago historically speaking, but that appears to be changing...
