I may be wrong, but I don't worry about mixing
different foods together. My old, healthy
body doesn't seem to mind if I eat whey
protein, juice, and flaxseed, all at the same
time.
Trust your intuition about what combinations
of food you eat. If you talk to the food,
as I do, and ask it to become the very best
of you, I don't think you'll have any problems.
