What is Resistant Starch?

The first question that may have popped up in your mind is what is resistant starch and how does it really work?

Resistant starch is a form of starch which does not break down completely in your body. Therefore, it is not fully absorbed by your stomach and intestines. Instead, it moves towards the colon and gets converted into short-chain fatty acids.

These short-chain fatty acids work as prebiotics to support the beneficial bacteria of your gut.

Because resistant starch is metabolized and processed in a way similar to that of dietary fiber, it also possesses a similar set of health benefits. In fact, it has been suggested that resistant starch can support satiety, balance blood sugar, and improve the digestive health.

Sometimes, it is also considered as a keto-friendly food item and is perfect for those following a low-carb diet. This is because it does not get digested and absorbed in the digestive system hence, does not produce spikes in blood sugar levels. Best of all, this type of starch is present in so many natural sources so, it becomes easy to incorporate it as a part of a healthy, well-balanced diet.
