Health Benefits of Fermented Foods Beyond Lactose Digestion

Te zalety of including fermented foods in thee diet extend well beyond lactose tolerance. Here are key area supported by by scientific revidence.

Enhanced Nutrient Biodostępność

Fermentation breaks down antinutritional factors like phytic acid and tannins, making minerals such as calcium, magnesium, zinc, and iron more absorbble. In dairy, the lactic acid presgetes calcium solubility. Vitamin content also rises: Kefir and artigurt are good sources of folate, riboflavin, and vinin B12. Some fermented foods even produce éin K2.
