my thoughts exactly. that is why i have gone off of oil pulling after being on oil pulling for a long time to see the difference. it is not noticeable to switch back and forth any more than it is to tell you have started the oil pulling again with its benefits. no big craving or crash by not doing it.
i also noticed that when the diet was correct in every way, the pull was clear and the oil took forever to get thin, another sign of clean blood. its all diet, baby, alll the way down. dont put crap in the body in the first place and there is no need for oil pulling, just the eating and wearing.
