What is the primary role of resistant starch once it reaches the large intestine in the purple potato?
Answer
It ferments and acts as a prebiotic, feeding beneficial gut bacteria
The resistant starch fraction of the purple potato travels undigested through the small intestine. Its destination is the large intestine, where it becomes an active participant in gut health processes. Here, the resistant starch undergoes fermentation by the resident microorganisms. This fermentation is essential because it means the starch is acting as a prebiotic, providing necessary nourishment that supports the growth and proliferation of beneficial bacteria, which is a key factor in maintaining a healthy and robust gut microbiome.
