--Dr. Weston Price's research was funded by the meat & dairy industry.
--Due to the era of the research, Dr. Prices conclusions are hardly applicable today - the condition of the typical 'human body' has very little similarities...once we've been subjected vaccines, heavy metals, fluoride and the tens of thousands of chemicals that weren't even on the planet in his lifetime, along with the radiation & daily bombardment of EMFs (not to mention irradiated foods, pesticides, herbicides & unnatural stress)...even a third grade 'scientist' would have to "invalidate".
--A mineral derived from a plant, isolated away from it's various enzymes, vitamins, alkaloids & phytochemicals is no more 'natural' to our body than munching a rock or shell.
--Our bodies were not designed (nor is it 'natural') to munch on rocks or shells (no matter WHAT 'ingredients' are in them)...that's just common sense (unless of course, we're deprived of food in any other form).
--Benefits? Risks? Short term? Long term? No doubt, there are MANY substances that "test" to be immensely beneficial in the 'short run'...but ground up rocks (in the long run) adversely and negatively impact the body (in all the ways elaborated in the original post).
--We can EASILY nourish our bodies with live foods in their natural forms and if necessary, supplement with seaweeds, algaes and other mineral rich herbs - that have ZERO potential for harm or long-term risk.
I sincerely (really!) appreciate the time & effort you put into your post. But on this forum we follow the works & protocols of two of the greatest healers that ever lived (Dr. Christopher & Schulze)...and they recommended strongly against ingesting meat/dairy and rock-based/isolated supplements or substances.
