Resistant starch: Benefits & how to incorporate it into your diet

Resistant starch is a type of carbohydrate that resists digestion in the small intestine and ferments in the large intestine. As it ferments, it acts as a prebiotic, feeding the good bacteria in the gut and offering numerous health benefits.

Benefits of Resistant Starch

While most starches break down into glucose, resistant starch bypasses digestion in the small intestine, avoiding a sugar rush. Instead, it passes to the large intestine where it is fermented by good bacteria. This healthy fermentation process leads to several benefits:

• Increased Feeling of Fullness: Helps reduce hunger.

• Prevention of Constipation: Promotes regular bowel movements.

• Decreased Cholesterol Levels: Contributes to heart health.

• Lower Risk of Colon Cancer: Supports colon health.

• Less Gas Production: Ferments slowly, causing less gas than other fibers.

 

Types of Resistant Starch

1. Physically Inaccessible Starch (RS1):

• Description: Starch trapped within the food matrix, preventing enzyme access.

• Examples: Partly milled or whole grains (oats, barley), legumes (beans, peas, lentils).

• Processing: Milling or grinding can release the starch, making it more digestible.

2. Resistant Granules (RS2):

• Description: Naturally resistant due to the nature of the starch granule.

• Examples: Raw potatoes, green unripe bananas, some legumes, high-amylose corn starch.

• Processing: Cooking may affect its resistance. RS2 is often found in raw foods or those not fully gelatinized during cooking.

3. Retrograde Starch (RS3):

• Description: Forms when gelatinized starch is cooked and then cooled.

• Examples: Cooked and cooled rice, potatoes, stale bread, cornflakes.

• Processing: Common in normal food processing, such as cooling cooked starches.

4. Chemically Modified Starch (RS4):

• Description: Man-made starch formed via chemical processes to resist digestion.

• Examples: Starch ethers, esters, and cross-bonded starches.

• Processing: Chemical modification interferes with digestive enzymes.

Effect of Cooking on Resistant Starch

Do Not Cook:

Some resistant starches, like those in oats, green bananas, and plantains, lose their resistance when heated.

Cook & Cool:

Cooking and then cooling foods like rice, potatoes, beans, and pasta can form another type of resistant starch.

Tips for Adding Resistant Starch to Your Diet

Cook and Cool:

Prepare rice, potatoes, beans, and pasta a day in advance and cool in the refrigerator overnight. Reheat before serving.

Overnight Oats:

Replace cooked oatmeal with overnight oats soaked in water, yogurt, milk, or non-dairy milk.

Add Lentils:

Incorporate lentils into salads or soups.

Sprinkle Flour:

Add 1-2 teaspoons of green banana flour, plantain flour, cassava flour, or potato starch to your meals.

Reducing Side Effects

Introduce Slowly:

Gradually increase fiber intake to avoid gastrointestinal discomfort.

Stay Hydrated:

Drink plenty of water to help your digestive system adjust.

Choose Variety:

Incorporate different types of fibers for maximum health benefits.
