There are obviously infinite levels of strictness -- grainfed vs.
grassfed meats, low carb, zero carb, etc. The way I choose to play the
game right now is to avoid grains altogether, have an occasional pat or
two of butter but otherwise no dairy. If I were to have a single bite
of pizza, I'd be messed up for days. It's simply not an option and I
don't stress or worry about it.
Eat as purist as possible and pay attention to this sign: If a
particular food gives you gas, it's not a good food for you. It's a
very good indicator.
