Resistant Starch for Diabetes and Prediabetes

Resistant Starch for Diabetes and Prediabetes

For many people with diabetes and poor blood sugar control, the word “starch” usually means something to be avoided at all costs. Starches are generally high in the carbohydrates that spike insulin and blood sugar, not to mention weight gain.

What Makes Resistant Starch Different? 

Resistant starch (RS) is a type of starch that is not digested in the stomach or small intestine, reaching the colon intact. As a result, it “resists” digestion, and will not spike either blood glucose or insulin, nor do we obtain significant calories from resistant starch. At Gut Garden, we use raw, unmodified potato starch in our Resistant Starch Prebiotic Fiber Blend. Unmodified potato starch has one of the highest concentrations of resistant starch of any food based source  - an added bonus is that the potato starch blends much more easily in drinks than other food based sources such as green banana flour. 

Studies on Resistant Starch and Glycemic Control 

  • A study published in the Diabetes Medicine Journal found that “Consumption of resistant starch improves insulin sensitivity in subjects with the metabolic syndrome.”
  • The American Journal of Clinical Nutrition found that resistant starch decreases blood glucose levels in response to meals.
  • A 2002 study published in the Journal of Nutrition found that consumption of 15 and 30 grams per day of resistant starch showed improved insulin sensitivity in overweight men, equal to the improvement that would be expected with weight loss of approximately 10% of body weight.

Second Meal Effect

Further, resistant starch has been shown to exert a “second meal effect.” Not only does resistant starch beneficially decrease the blood sugar response after a meal at the time it’s consumed, but blood glucose and insulin levels also rise less than would otherwise be expected with the next meal.

Combine Resistant Starch with Soluble Fiber for even Better Results

Diabetes Care Journal published a study concluding that not only does RS improve postprandial plasma glucose and insulin, but that “the reduction in glycemic response was enhanced by combining resistant starch and soluble fiber.”

Gut Garden's Resistant Starch Prebiotic Fiber Blend

Gut Garden’s blend remains the only resistant starch supplement on the market that combines resistant starch with 4 soluble fibers - acacia fiber, larch arabinogalactan, glucomannan, and chicory root inulin.
