Its Just Gas
BACTERIA IN GUT COULD INCREASE OBESITY _ An intriguing theory is developing that the risk of obesity has something to do with
the type of bacteria in one’s gut. A new study by researchers at Cedars-Sinai Medical Center, for example, has found that people with gut bacteria that causes a high amount of methane gas tend to have higher body mass index. Dr. Mark Pimentel and his colleagues at Cedars gave 58 people a breath test to measure methane gas. About 20% of the participants tested positive for methane. Those people also had a body mass index up to 7 points higher than patients who did not show the presence of methane. It’s possible that methane from methane-producing gut bacteria can slow down digestion and increase the uptake of calories, the authors said.
