Microbial balance in the intestinal microbiota and its association with diabetes, obesity and allergic disease.

Recent studies have been considered to symbiotic interactions of the human gastrointestinal microbiota and human lifestyle-related disorders. The human gastrointestinal microbiota continuously stimulates the immune system against opportunistic and pathogen bacteria from infancy. Changes in gastrointestinal microbiota have been associated with numbers of human diseases such as allergic diseases, autoimmune encephalitis, atherosclerosis, colorectal cancer, obesity, diabetes etc. In this review article, we evaluate studies on the roles of human gastrointestinal microbiota and interference pathogenicity in allergic diseases, obesity, and diabetes. Several studies indicated association between allergic diseases and changes in bacterial balance such as increased of Clostridium spp., some species of Bifidobacterium spp., or decreased of Bacteroidetes phylum and some species of Bifiobacterium spp. and production of specific short-chain fatty acids due to food type, delivery modes of infant, infant evolvement environment and time of getting bacteria at an early-life age. In addition, obesity and diabetes are associated with food type, production of short chain fatty acids undergo fermentation of the intestinal microbiota, metabolic endotoxemia, endocannabinoid system and properties of the immune system. Well-characterized underlying mechanisms may provide novel strategies for using prebiotic and probiotic to prevent and treatment of allergic diseases, obesity, diabetes, and other lifestyle-related disorders.
