Raw potato starch looks like flour and can be blended into smoothies, yoghurt, pudding and unbaked pie filling.
resistant starch is any starch that can’t be digested by the juices produced in either the stomach or small intestine.
Rather the starch has to be digested by the bugs in your large intestine and bowels. These bugs produce beneficial short chain fatty acids.
American diets are typically low on resistant starches. So the lower gut does not produce sufficient quantities of short chain fatty acids and whatever else scientists will discover are produced in the lower gut in coming years.
This is a new field of study.
