These SCFAs directly correlate with metabolic benefits, including elevated glucagon-like peptide-1, a reduction in HbA1c, and improved blood-glucose regulation [16].Conversely, a lack of dietary fibre promotes proteolytic fermentation, where bacteria metabolize protein into harmful post-biotics such as ammonia and phenols linked to inflammation and insulin resistance [17]. The gene discussed is GCG; the disease is Insulin resistance.
