Hormonal

Gut microbiota composition directly influences host glycemic control and insulin sensitivity through mechanisms including incretin secretion, short-chain fatty acid (SCFA) production, and bile acid metabolism.

Your gut bacteria play a key role in how your body handles sugar. Eating non-digestible carbohydrates (like inulin and oligofructose) can feed beneficial bacteria that produce short-chain fatty acids and stimulate hormones (GLP-1) that improve insulin response. This suggests that dietary fiber is not just for digestion but is a metabolic tool for glycemic control.

GoodSupportsHIGH confidence
We will examine key biological molecular mechanisms underlying the impact of gut microbiota on host glycemic control including: incretin secretion, short-chain fatty acid production, bile acid metabolism, and adipose tissue regulation.
