The composition of intestinal bacteria and other micro-organisms—called the gut microbiota—changes over time in unhealthy ways.
Researchers previously found that the gut microbiota—containing both beneficial and harmful microbes—can affect human health in many ways and that the mix of this community of microscopic organisms differs in people with Type 2 diabetes compared with healthy individuals.
However, the new study shows that alterations in the gut microbiota already occur in the early stage of diabetes development known as impaired glucose tolerance or pre-diabetes.
Your gut bacteria could predict your risk of diabetes.
Unlike other studies that evaluated gut microbes at one time point in diabetic people, the new study, analyzed the microbiota composition over one year in adults with varying blood glucose (sugar) and insulin levels.
Study subjects were divided into four groups based on changes in their glycemic, or blood sugar, control, as demonstrated by the oral glucose tolerance test (or the fasting glucose blood test in group 2), between the start and end of the one-year study.
The four glycemic control groups were (1) stable (unchanged) normal, (2) stable impaired, (3) worsened, and (4) improved. At the end of the study, the men gave stool samples for analysis of their gut microbiota.
The researchers found that men whose blood sugar control stayed normal over the year had more gut bacteria that are considered beneficial for metabolic health, whereas those who stayed pre-diabetic had fewer beneficial bacteria and more harmful bacteria. In addition, the group whose glycemic control improved (group 4) had even more abundant healthy bacteria than the group that kept normal blood sugar control throughout the year.
Based on other research her group has conducted, she speculated that the foods we eat affect our diabetes risk through our gut microbiota. If the makeup of tiny organisms in the intestinal tract is indeed responsible for the development of Type 2 diabetes, she said it is possible that changing one’s gut bacteria could prevent diabetes.
Reinstating healthy bacteria can help you to balance the microbes in the digestive tract, which can prevent serious health issues such as diabetes, insulin resistance, high cholesterol, high blood pressure and skin disorders. We recommend that you follow a healthy diet, like the Manna Diet and take the Manna GUT Support, with essential probiotics, digestive enzymes, colostrum and l-glutamine, to reinstate health to your digestive tract.
