Probiotics are the beneficial bacteria that live in and on your body. Probiotics are also referred to as flora or friendly bacteria. Probiotics have a major influence on the function of your immune system and your state of health. If you have a robust, healthy flora, you will most likely have a strong immune system that resists pathogens and other outside invaders. You also have a well-controlled immune system that does not overreact to foreign substances, and you will be less likely to have allergies, asthma, eczema, and autoimmune disorders. You will also be less likely to develop chronic illnesses such as diabetes, obesity, cancer, depression, and other disorders. You can get probiotics from lactofermented foods or from probiotic supplements. The Probiotics for Perfect Health cookbook includes tips for probiotics, and includes more than 30 recipes that can be made with probiotics including a variety of Krauts, juices, kefirs, kombucha teas and cheesecakes.
