Scientists from the University of Copenhagen analyzed the feces of Danes to find out why some people
Microbiologists have studied the residual energy inhuman feces to understand how this might be related to being overweight. From the mouth through the esophagus, stomach, large and small intestines and to the rectum, food can move from 12 to 36 hours. Initially, the researchers suggested that the longer it lingers in the intestines, the more energy the body extracts.
Observations have shown that this is not the case:in people with similar diets, the passage of food through the digestive system takes a different time. At the same time, this period is the shortest in people who have a B-type microbiome predominate (with a predominance of Bacteroides bacteria). This same group has the least energy in residual feces and is, on average, more prone to obesity.
Each person has a unique composition of intestinalbacteria, which is shaped by genetics, environment, lifestyle and nutrition, scientists explain. Humans can be divided into three groups based on the presence and abundance of the three main groups of bacteria: B-type (with Bacteroides predominating), R-type (Ruminococcaceae), and P-type (Prevotella). A new study shows that the type of bacterial microbiota has a significant impact on the tendency to be overweight.
Researchers believe that understanding the nature of the tendency to overweight will help to diagnose and prevent the development of associated diseases in a timely manner.
