Type 2 diabetes is on the rise, affecting a significant portion of the global population. The gut microbiome plays a crucial role in blood sugar regulation, with dietary choices directly impacting gut health and metabolism. Short-chain fatty acids from gut bacteria enhance insulin sensitivity and reduce inflammation. Personalized nutrition is key to managing blood glucose levels, while gradual carbohydrate introduction can improve gut function. Strategies for rebuilding gut health are essential in preventing diabetes and maintaining metabolic balance.
