Being new to this forum, and having read this long, largely 2016 discussion on starch, longevity in Blue Zones etc, I find it perplexing that a bare reference to the added poisons that make certain starches toxic were given scarce discussion in the Costa Rica example. We know, for instance, that since the 1970's that USA corn and grain were seriously modified genetically. Doesn't anyone remember the media on places with starving children like Biafra, and the"We Are Going To Feed The World" campaign? and ever after, farmers forced to use the govt sanctified seed for millions of acres of wheat ? Then, the now banned in Europe Monsanto came in to help with the cost of processing, by plane spraying of glyphosate, aka RoundUP, to defoliate said grains. Bazillions of dollars saved in threshing: man hours, fuel, machine wear and tear etc. Grains laid in the fields overnight, sometimes longer,and mildewed or molded with the dew....bleached that wheat then to clean it up, and then the hippie generation sez We Don't Want Bleach, so they used another solvent, thus another choice: Unbleached. Meantime, the gooey, sticky glop that evolved was so devalued, the FDA sez well, its not really fit for human consumption, but if you ENRICH it....hence we now have a label that begins Enriched Flour, with Thiamine, Riboflavin,B-1, B-6 etc added.to make it consumable. Not healthy, consumable. Does anyone really believe that industry spent $$for vitamin additions because they wanted Americans to become Rocket Scientists? Consequently and years after, we do see a documented rise in Diabetes, FAT AMERICA, and loads of people who think they are gluten intolerant, when quite likely they are all just poison intolerant. Equally as deplorable, the meat and dairy industry as subsidized by the govt., where milk cows live only 4 years instead of 25 because they are not on a grassy field allowing their 4 stomachs to process grass, but instead raped and caged to be attached to heavy milking machinery, all the while slurping a gruel of gmo fatty corn and water slush to stay alive. I imagine the end product of this industry to be rife with toxic terror hormones, blood, pus, all homogenized and pasteurized with "vitamin D" and a host of cosmetic fixes into a porous plastic container that I don't even want to think about putting in my body. (As a former Director in American Red Cross, I can state that literature for emergency water storage indicates Never, Ever to use plastic milk containers because of their porosity.) I see other threads talking about mold or mycotoxins that RayPeat warns about in certain foods, but are these topics Verboten to speak on? I thought the time and effort by the member revealing exactly what his diet looked like was thoughtful and gracious in its offering, especially listing his milk proteins as coming from goat products. Additionally, not one mention of the discovery and cultivation of Einkorn, the original "staff of life" wheat, which upon analysis was found to have the same chromosome count as humans, instead of the 44 modifications in current wheatology, is nearly gluten free, and extremely high in protein. This should give the ENTIRE discussion of starch pause. Or, the option of some northern cultivars in Montana which are left to defoliate with the first freeze, without such use of documented poison as glyphosate, and whose seed cannot be the same as gmo breadbasket America is eating to the detriment of health, intelligence and creativity. Is the Ray Peat Forum at risk for shutdown by Corporate powers for such discussion?
