One of the stupidest things that European and other settlers ever did to this continent was to nearly exterminate the American Bison (buffalo). As seen in this section, the free-range bison provides a nutritious alternative to feedlot beef, red meat providing the vitamins B6, B12, and folic acid needed to get rid of toxic homocysteine, and to get our L-cysteine and vitaletheine modulator pathways back on track and keep them there. Just don't microwave red meat, brewers' yeast, or your brain since microwaves appear to be destroying vitamin B12, and perhaps liberating carcinogenic cobalt. This may be the mechanism for concerns about cell phones.
