A new research has found that the bacteria present in the gut may affect obesity. Our gut is filled with beneficial bacterial species. These species provide digestive aids, nutrients and energy. For good health, it is imperative to maintain a proper gut flora. According to the new research, it has been found that the type and amount of bacteria in the digestive tract can not only aid digestion but also reduce obesity.
The Study
An investigative study was carried out at the Washington University School of Medicine on the digestive tract of thin and obese people. Nearly 5,000 bacterial species are present in our gut, all of which have not been identified yet. The main three bacterial species in the human gut are Actinobacteria, Bacteriodetes and Fimicutes.
Another study established the fact that in order to maintain a good health, it is necessary to have a proper ratio between the Bacteriodetes and Fimicutes. With age, the ratio gradually changes and this may be a reason for onset of adult obesity.
Research Findings
New research found that people who were obese had large amounts of Fimicutes whereas leaner people had large amounts of Bacteriodetes. The ratio of the bacterial flora changed in the guts of obese people, when they were asked to follow fat reducing diets.
The ratio came down to same level as the ratio of bacteria present in the guts of leaner individuals. Hence, as the obese individuals lost weight, the amount of Bacteriodetes increased in their guts. To aid the restoration of digestive flora in the gut, probiotics can be added to the diet. This enhances the digestive enzymes as well as aids in digestion.
