What are fermented foods?
Fermented foods are products that have been transformed by the action of beneficial microorganisms, such as bacteria, yeast, and molds. These microorganisms break down sugars and starches in food, converting them into lactic acid, alcohol, or acids, which act as natural preservatives. Common examples of fermented foods include yogurt, sauerkraut, kimchi, kefir, kombucha, and various pickled vegetables.
The fermentation process not only enhances the shelf life of these foods but also boosts their nutritional value. The microorganisms involved can increase the bioavailability of vitamins and minerals, while probiotics, which are beneficial bacteria found in many fermented foods, may promote gut health and overall well-being.
What are the health benefits of fermented foods?
Fermented foods are celebrated for their numerous health benefits, which stem largely from the presence of probiotics.
