THURSDAY, May 10 (HealthDay News) — Levels of certain gut
bacteria and low protein intake may raise children’s risk of being obese,
new research suggests.
The study included 26 obese and 27 non-obese children aged 6 to 16 who
completed a dietary and physical activity survey. Stool samples from the
children were analyzed to assess the presence of different types of gut
bacteria.
Overweight and obese children had different proportions of various gut
bacteria than normal weight children. The ratio of Bacteroides
fragilis to Bacteroides vulgatus was 3:1 in overweight and
obese children, while this ratio was reversed in normal weight children,
the investigators found.
Like the normal weight kids, children who ate more protein also had
lower levels of B. fragilis. That suggests a possible connection
between dietary protein and obesity, according to the researchers from the
University of Hasselt and the University of Antwerp in Belgium.
The study, slated for presentation Wednesday at the European Congress
on Obesity in Lyon, France, revealed no significant associations between
gut bacteria and levels of physical activity.
“Our results suggest that low concentrations of Bacteroides
fragilis group bacteria, together with a low protein intake during
childhood, could lead to the development of obesity,” Liene Bervoets, of
the University of Hasselt, and colleagues explained in a news release from
the European Congress on Obesity.
While the findings indicate an association between a certain
composition of gut microflora and childhood obesity, the researchers did
not prove that having the wrong gut microbes can cause obesity.
But the study authors noted that the findings suggest that manipulating
the makeup of gut microbiota through diet, prebiotics or probiotics may
help prevent obesity. Prebiotics and probiotics are ingredients in food
that may stimulate the growth of helpful bacteria in the digestive
tract.
Bervoets also suggested that existing guidelines on protein
consumption may need to be revised.
Because this study was presented at a medical meeting, the data and
conclusions should be viewed as preliminary until published in a
peer-reviewed journal.
