Bifidobacteria for treating diabetes and related conditions

Abstract

This invention relates to new uses of Bifidobacteria (particularly, although not exclusively, probiotic Bifidobacteria ), and to food products, feed products, dietary supplements and pharmaceutical formulations containing them. The bacteria are suitable for the treatment of diabetes (particularly Type 2 diabetes), obesity and related conditions, metabolic syndrome, insulin resistance, and impaired glucose metabolism and consequences thereof, lowering tissue inflammation, treating hepatitis, myositis and cardiovascular conditions.
