Opinions differ about the proposed benefits of refined resistant starch, such as the humble Bob's Red Mill potato starch. But I think it's widely agreed that potato starch isn't metabolized like regular starch, and is metabolized by intestinal bacteria.
Does that mean that the nutritional label is wildly incorrect? It describes potato starch as a pure carbohydrate with 4kcal/g. Does anyone know, or want to venture a guess, as to the real macronutrient impact humans end up with after consuming potato starch? My understanding is that some of it is converted into fatty acids that we do metabolize, but I don't know what proportion of it, what the efficiency* of that process is, or what happens to any that's left over.
* By efficiency I mean, how many of the calories in the starch are converted into calories of fat? But since the fatty acids are a byproduct of the bacteria trying to extract their own calories from the starch, I guess from their perspective this is a measure of inefficiency instead.
