Yea, mine too. I tried it after reading this thread and have already given up and let them have the dairy and the meat too. For one, mine wouldn't stay elated, just kept slipping back to happy. On top of that, in one of the two families that I tried it, they already both got sick once and their health bars are lower (in both families) than in all my other families that have always been eating all four food groups. I really don't think feeding them a vegan or a vegetarian diet actually makes them healthier in this game. Maybe it does in real life, but I don't see the evidence of it in my game and I can't stand those emails, lol!
