What Fermentation Creates
The transformation goes beyond preservation:
- Bioavailability increases — fermentation breaks down anti-nutrients like phytic acid, making minerals more absorbable
- New nutrients appear — bacteria produce B vitamins, vitamin K2, and bioactive peptides
- Digestibility improves — much of the lactose in milk is consumed during fermentation, which helps many lactose-intolerant people tolerate yogurt
- Beneficial bacteria survive — live-culture foods deliver probiotics in a food matrix that helps protect them through stomach acid.
