All of us carry trillions of bacteria with us for the whole of our lives, & they protect us from disease. This protection is under threat by ultra-hygienic living conditions, & by the overuse of antibiotics. Probiotics (beneficial microbes) can support our resident microbes (microflora), & ' Probiotic Allies' explains how. It describes the microflora in different parts of the body, reports on high-quality evidence that proves probiotics work, & tackles practical questions about the use of probiotics. Conditions covered include diarrhoea, constipation, IBS, IBD, lactose intolerance, gastric ulcers, allergies & female urogenital infections.
