Their statements are both right and wrong! If you're eating meat raised on a non-gmo, grass fed, grain free farm, than you're eating healthy nutritious meat!!! But, if you're buying your meat purchased from commercial grocery stores, that are full of anti-biotics, grain fed, and whatever else they pump into the poor diseased animal, then yes, of course you're going to get sick and possibly end up with cancer...if not cancer, for sure body aches and pains, auto-immune diseases and very poor quality of life! Make sure you know what you're buying and never listen to those who don't understand nutrition! Buyer beware!
