Some time back I had posted about a recurring navel infection I get everytime I consumed Mushrooms or Shellfish. It seems I may have a fungal issue due to Hypothyroidism. Mushrooms and shellfish are very high in Chitin (Fungal Protein) and supposedly fungi use Chitin (along with cellulase, beta glucan) to strengthen themselves. It seems humans dont make Chitinase enzyme which breaks down Chitin. I found natural sources of Chitinase enzymes are mainly fruits - Avocado, Kiwi, Papaya, Banana, Tomatoes. From that list I can only tolerate Kiwis. Just wandering if there are other sources besides fruits which are high in Chitinase? Silkworms (Serrapeptase) also contain chitinase but may go the supplement route if natural foods dont help. Thanks
