What preparation method maximizes resistant starch benefits in purple potatoes?
Answer
Cooking and then chilling
To maximize the prebiotic benefits derived from resistant starch, which is a specific type of fiber that resists digestion in the upper GI tract, the method of preparation is crucial. The highest levels of resistant starch are achieved when potatoes are cooked thoroughly and subsequently chilled, rather than being reheated. This principle makes preparing a dish like a chilled purple potato salad, consumed with the skin on, an excellent strategy for delivering substantial prebiotic fiber content to the colon for fermentation.
