The intestinal flora is currently the big topic in the health sector. More and more new findings surprise us: The bacteria not only significantly influence our immune system and our psyche, but are also associated with allergies, secret inflammations and diseases such as Alzheimer's or type 2 diabetes. This book shows which bacteria live in the intestine and how you can support them in their work with the right diet. This can be done with probiotics - foods that contain viable microorganisms, such as lactic acid bacteria and yeasts - and prebiotics - food ingredients that promote the growth and activities of bacteria. In addition, the book provides 30 delicious recipes, such as for kombucha, labneh cheese, kvass, kimchi and sauerkraut.
