Postprandial glucose and insulin response to a high-fiber muffin top containing resistant starch type 4 in healthy adults: a double-blind, randomized, controlled trial

- Fiber fortification in a muffin top can be achieved with resistant starch (RS) type 4.
- RS type 4 reduces postprandial blood glucose (venous and capillary).
- Postprandial insulin concentrations were correspondingly reduced.
- RS type 4 offers fiber fortification for blood glucose control.
