The Claim

In healthy lean and overweight adults, resistant starch suppresses postprandial free fatty acid rebound following a glucose load, whereas inulin does not, and this suppression is correlated with improved second-meal glycemic control, indicating that free fatty acid dynamics may represent a more relevant metabolic target than short-chain fatty acid production.

How it works
1 study reviewed
In plain English

In healthy adults, consuming resistant starch reduces the rise in free fatty acids after a meal containing glucose, while inulin does not, and this reduction is linked to better blood sugar control at the next meal, suggesting free fatty acid changes are more important than short-chain fatty acid changes for metabolic regulation.

See the scientific wording

In healthy lean and overweight adults, postprandial free fatty acid rebound after a glucose load is significantly suppressed by resistant starch but not by inulin, and this suppression correlates with improved second-meal glycemic control, suggesting FFA dynamics may be a more relevant metabolic target than SCFA.

Why this might work

When resistant starch reaches the colon, it releases glucose slowly, which keeps blood sugar levels steady and tells the body to stop breaking down fat. Lower fat levels in the blood let insulin work better in muscles and the liver, so the next meal causes less of a blood sugar spike.

    Resistant starch helped lower the spike in fat levels after eating sugar and made blood sugar better the next meal, while inulin didn’t do either. So yes, resistant starch works better for this than inulin.
