Experts say our genes, not just our diet, can drive gut health and help protect people from diabetes.
Sydney-based researchers at the Charles Perkins Centre have identified a genetic component influencing the composition of the gut microbiome and its subsequent impact on metabolic health.
While dietary factors are acknowledged to play a significant role in gut health, the research suggests that genetics also contribute significantly.
The study focuses on alpha-defensins, small proteins or peptides produced by genes, with varying levels observed between individuals.
"The microbiome is like a garden, it contains beautiful plants but it also contains weeds," Professor David James from the Charles Perkins Centre said.
"The beautiful plants contribute to good health, and the weeds bad heal
