I don't have any food allergies; except shellfish and peanuts... not gluten intolerant either (I've been tested for celiac disease). Dairy doesn't agree with me, but only certain things. I can eat cheese and small amounts of yogurt and cottage cheese. But, I absolutely cannot drink milk. Probably why I have the osteopenia. Besides, I hate the taste of it, too.
Generally, the higher protein, "good carbs" way of eating is best for me, but I have to add in more carbs when I am doing a lot of riding or running.
