Hello,
I would like clarification on the term resistant starch – I came across it in an article about fiber. What is its role and how is it related to fiber?
Thank you.
Resistant starches are those that resist the digestion process. They essentially behave similarly to soluble fiber—they undergo fermentation by the activity of the gut microbiome in the colon. The result of this process is the production of short-chain fatty acids, which are an important energy source for the cells forming the lining of the colon. Among other benefits, resistant starches have additional (health-promoting) effects, with one of the most important being their ability to enhance the sensitivity of cells to insulin (very important for diabetics).
There are several types of resistant starches, found in grains, legumes, seeds, tubers (potatoes, sweet potatoes), or fruits (unripe bananas—during the ripening process, these resistant starches turn into digestible ones).
