Usually by Monday, we run out of delicious meat/fish/eggs. So we eat tofu for dinner. Is it okay for once a week? And also, is it okay to eat rice a little everyday? It's like 80/20. What do you think?
I probably wouldn't eat the tofu that often, but honestly, I don't really care for it anyway. If you really like it and don't seem to be having a bad reaction, I think a smallish portion would be fine as part of your 20%. If you notice any problems, though, that'd probably be the first place I would look at eliminating to see if it gets better. Soy is just so bad from a phytoestrogen standpoint that I personally put it below wheat and legumes on the scale of "paleo-bad."
I think a bit of rice everyday is absolutely fine.
Eating tofu once per week is better than eating it twice or more per week, but it still isn't as good as not eating it. I also don't see the taste to be all that appealing anyway. As to the rice, it is not inherently bad, so if it is fitting into your diet, and you aren't gaining weight (unless that is your goal), then go for it.
I don't eat soy or rice, but I do have a few favorite tofu dishes from when I was a vegan that I keep thinking I should change to meat. it's mainly the sauces/veggies with it that I find appealing.
I think as long as you follow paleo pretty well, a meal of tofu a week won't be too bad. I am only strict because of an AI condition. if I didn't have this condition, you best believe i'd be eating anything I want.
I suppose tofu isn't as bad a cheat as some other noms out there, but do consider the phytoestrogens. I don't miss tofu, but I don't feel quite as guilty about cheating on tofu as say, ice cream or M&Ms. As for rice, white rice is generally accepted as ok if you're doing intense cardio training.
