🧬 How Tofu, firm with calcium sulfate and magnesium chloride (nigari) Affects Your Health

💪

Testosterone 8% DV

Zinc (undefined% DV) supports testosterone production. It's a cofactor for 5α-reductase and inhibits aromatase.

🧘

Cortisol & Stress 9% DV

Magnesium (undefined% DV) calms the nervous system. It blocks NMDA receptors and reduces stress-induced cortisol spikes.

🧘

Cortisol 4% DV

Vitamin B6 (undefined% DV) helps produce serotonin and GABA — calming neurotransmitters that counter cortisol.

🦋

Thyroid 18% DV

Selenium (undefined% DV) converts T4 to active T3. Essential for thyroid function.

🏥

Anemia

iron + folate. Iron-deficiency is the most common nutritional deficiency. Vitamin C increases non-heme iron absorpt.

🏥

Hypothyroid

selenium + zinc. Thyroid hormone synthesis requires iodine + tyrosine for T4 structure, selenium for T4→T3 conversion.

🩸

Iron 9% DV

9% DV. Supports red blood cells and oxygen transport. Low iron = fatigue, brain fog.

⚡

Magnesium 9% DV

9% DV. Calms nerves, relaxes muscles, supports sleep.

Frequently Asked Questions

Does Tofu, firm, prepared with calcium sulfate and magnesium chloride (nigari) affect hormones?
Yes — Tofu, firm, prepared with calcium sulfate and magnesium chloride (nigari) is rich in selenium (18% DV), which Required for T4→T3 conversion (deiodinase enzyme). Selenoproteins protect Leydig cells from oxidative damage.. selenium supports T3 (active thyroid) and Testosterone production.
Does Tofu, firm, prepared with calcium sulfate and magnesium chloride (nigari) contain anti-nutrients?
Phytates (reduce zinc, iron, calcium absorption 20-60%). Lectins (can irritate gut lining — destroyed by proper cooking). 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.
