What is Resistant Starch?
Resistant starch is a type of carbohydrate that resists digestion in the small intestine, functioning similarly to dietary fiber. There are four main types of resistant starch:
Types of Resistant Starch
- Type 1: Found in whole or partially milled grains and seeds, it is physically inaccessible to digestive enzymes.
- Type 2: Naturally resistant and found in raw potatoes and green bananas, this type remains intact even after cooking.
- Type 3: Formed when starchy foods are cooked and then cooled, such as cooked rice or pasta. This process retrogrades some of the starch, making it resistant to digestion.
- Type 4: A chemically modified form of starch used in various food products, which is specifically created to resist digestion.
Understanding these types can help you make informed choices about your diet and how to incorporate resistant starch effectively.
Health Benefits of Resistant Starch
The benefits of incorporating resistant starch into your diet are numerous:
