Oops, didn't realize the whey stuff counted as a supplement. And lactose-intolerance does make it harder -- no yogurt. Soy milk is still available, though.

I wouldn't want to eat tuna every day because of the mercury. I eat tuna about once a week, salmon about twice a week, and assorted whitefish two or three times a week. Whitefish is versatile; you can cook it lots of ways so it doesn't get boring.
