Resistant starch is a type of dietary starch that avoids digestion in the small intestine and, as a result, behaves more like dietary fiber than traditional starch. Instead of being broken down into glucose and absorbed in the small intestine, resistant starch passes through to the large intestine, mostly intact, where it interacts with the gut flora. 

Resistant starch has gained attention for its potential health benefits, which can include:

1. Improved blood sugar control
2. Resistant starch acts as a prebiotic, promoting the growth of beneficial gut bacteria and improving gut health.
3. Lower cholesterol levels

How Can I Get More Resistant Starch?

Foods rich in resistant starch include green bananas, potatoes, steel-cut oats, plantains, and pearl barley. Cooking and processing methods can influence the amount of resistant starch in foods, with cooking and then cooling being a common way to increase resistant starch content. However, it's important to note that individual responses to resistant starch can vary, and excessive consumption can lead to gastrointestinal discomfort in some individuals. As with any dietary changes, consulting a healthcare professional for personalized guidance is advisable.
