Just something you need to pay more attention is the loads of
natural antinutrients you're ingesting — fiber (a toxin that the body tries to eliminate), phytic acid (omnipresent), lectins and trypsin inhibitors (legumes), oxalic acid (spinach),
goitrogens (kale and al cruciferous veggies), phytoestrogens (omnipresent), glucosinolates, tannins, saponins, arsenic (omnipresent), heavy metals (most of US soil is poisoned).
Certain veggies, especially the cruciferous veggies, contain
natural chemicals called
goitrogens that can interfere with thyroid hormone synthesis.
