Health Condition Relevance
Pcos
magnesium, zinc, fiber. Insulin resistance drives 70%+ of PCOS. These nutrients improve insulin sensitivity, reduce androgen.
Anemia
iron, folate. Iron-deficiency is the most common nutritional deficiency. Vitamin C increases non-heme iron absorpt.
Gut Health
fiber, zinc. Soluble fiber→SCFA (butyrate) fuels colonocytes. Polyphenols metabolize into anti-inflammatory compo.
Hormonal & Metabolic Impact
Cofactor for 5α-reductase (T→DHT). Required for androgen receptor function. Inhibits aromatase (T→estradiol).
Reduces SHBG → more free T. Lowers cortisol by suppressing ACTH. Required for vitamin D activation (which also supports T).
Binds excess estrogen in gut for excretion (enterohepatic circulation interruption). Slows glucose absorption → lower insulin spikes.
Anti-Nutrients & How to Reduce Them
⚠️ Phytates (reduce zinc, iron, calcium absorption 20-60%)
⚠️ Lectins (can irritate gut lining — destroyed by proper cooking)
⚠️ Protease inhibitors (reduce protein digestion — destroyed by cooking)
⚠️ Tannins (reduce iron absorption)
Mitigation: Soaking 12-24h reduces phytates 30-50%. Cooking destroys lectins and protease inhibitors. Fermentation (tempeh, miso) reduces all anti-nutrients. Sprouting increases nutrient bioavailability.
Benefits (fiber, protein, minerals) far outweigh anti-nutrient concerns for most people.
