For the record, I cut dairy completely out of my diet in 1999 (over 5 years before I ever committed to a full-Vegan diet)... This was due to an allergy that I developed in my adolescent years to dairy that effected my sinuses and everything connecting to them. For a good part of my teenage years, I suffered from severe ear infections and chronic Vertigo (which is completely miserable). It took me a few years of to finally realize that the antibiotics were only temporarily subduing a much bigger problem. I did my research and finally found the source. A lot of people don't realize how hard milk, whey, and other dairy products are on the sinuses and respiratory system, and the dairy industry would like you to believe that you need milk to get calcium. That notion is as oxymoronic as you can get. Although not everybody has as severe an allergy to dairy products as I did, I just wanted to point out that after years of battling with ear and sinus infections, eliminating dairy completely cured my problems. Anyone with similar problems may want to try it for a while.
