What is one function of resistant starches in the digestive system?

Resistant starches play a significant role in the digestive system, particularly when it comes to fostering a healthy gut microbiome. When consumed, resistant starches reach the large intestine undigested, where they act as a prebiotic, providing a food source for beneficial gut bacteria. This fermentation process results in the production of short-chain fatty acids (SCFAs), which in turn support the growth and maintenance of healthy bacteria. A higher population of good bacteria is associated with a variety of health benefits, including improved digestive health, enhanced immune function, and potentially reduced risk of chronic diseases.

This understanding of resistant starches emphasizes their importance in promoting gut health, distinguishing them from other options that focus on metabolic rates, fat breakdown, or taste enhancement, which are not primary functions of resistant starch.
