Now a new study suggests that shifting to a fiber-filled healthy diet with fruits and vegetables may increase the bacteria species in our gut and that in turn, may improve metabolic abnormalities linked to obesity.
Published in Nature yesterday, the study works in tandem with another in the same issue that suggests having a diverse array of bacteria makes a difference to our health. People with less bacteria diversity had more insulin resistance and inflammation, which are risk factors for cancer. They also were also more likely to gain weight.
In the diet study, researchers looked at the microbial diversity among 45 people who were overweight or obese. The scientists analyzed the number of bacteria genes, dividing the group into those who had low or high bacterial diversity: 40 percent had low; 60 percent high. To start with, the people with less bacterial diversity had higher insulin resistance, triglycerides, and inflammation. Continue reading
