The Claim
In healthy lean and overweight adults, consuming 28 grams of resistant starch with a 75-gram glucose load reduces postprandial glucose and insulin responses during a subsequent meal by approximately 15–20%, independent of changes in serum short-chain fatty acids, suggesting that mechanisms other than SCFA—such as reduced free fatty acid rebound—may mediate improved glycemic control.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Consuming 28 grams of resistant starch with a 75-gram glucose load reduces postprandial glucose and insulin levels by 15–20% during a subsequent meal in healthy lean and overweight adults, regardless of changes in serum short-chain fatty acids.

Eating resistant starch slows down how quickly sugar enters the blood after a meal. This steady sugar release tells the body to stop breaking down fat, so less fat enters the bloodstream. Lower fat levels in the blood let muscles and the liver respond better to insulin, so the next meal causes less of a spike in blood sugar and insulin.
What the research says
1 studyWhen people ate a special type of starch with a sugary drink, their blood sugar and insulin stayed lower at their next meal—even though their gut bacteria didn’t produce more short-chain fatty acids. Instead, it seems less fat in the blood was responsible for the benefit.
