I do agree with you. Raw meat = parasites. Or we have to find a way to eat it with anti parasites herbs. garlic?
I've noticed the same thing with meat, the more I eat it, the more trouble I have, vision, etc. I eat very few meat now, no more than once or twice a week, and my health is better on many points. Also, the claim that saturated fats are good for health, it's very surprising for an European as me.
But I like other paleo stuff, hygiene for instance is interesting, I will try more and more the no-poo and the other idea it brings.
