i completely agree with the environment being everything. in fact, i think introducing strains that are no longer present due to antibiotics, et al, is NOT necessary because i believe there is only one bacteria and it morphs according to the environment. that, or all types are omnipresent and it is the flourishing of the different types that we are able to detect their effects.
either way, environment is all. i love what andreas said about eating corpses. this is so very true. it is like the whole study of cancer - the cancer is not the disease, it is there to eat the dying flesh. something else is doing the killing, and that is the accumulated waste and toxins causing this death through constipation of the flow of blood, lymph and nerve channels.
even so, i dont think it hurts to eat a little dirt now and then! what the heck. it is not only what we are made of, its free. i am also convinced of cayces admonition to eat food from where you live. not only do the environments they grow in match the environment you live in, but the soil goes into that food. there is a lot to be said for living where you were born and ingesting the same soil organisms you did as a kid. the poorest children, health-wise, are the ones growing up in the most sterile environments and eating the most processed foods.
