Fermented foods are foods and beverages that have undergone controlled microbial growth through the process of fermentation. Fermentation is an anaerobic process in which microorganisms like yeast and bacteria break down food components (e.g. sugars such as glucose) into other products (e.g. organic acids, gases or alcohol).
This gives fermented foods their unique and desirable taste, aroma, texture and appearance.
Fermented foods are high in probiotics. By eating or drinking fermented foods and beverages, you are adding essential and active bacteria and enzymes to your intestinal flora, increasing the health of your gut microbiome and digestive system and enhancing the immune system.
