There was also quite a bit of scientific explanation in the info graphic I included before.
On top of animal foods being more nutritious & more bioavailable, plants protect themselves by producing inflammatory toxins & anti-nutrients:
glycoalkaoids, sulforaphane, salicylates, lectins, phytates, cyanide, trypsin inhibitors, oxalates, tannins, saponins, etc
There really is no lack of availability in scientific info on this subject, just a lack of financial incentive to acknowledge & promote what is true & a lack of desire to hear the truth on the part of carb addicted & brainwashed normies.
