Digestive-resistant starches are indigestible low-viscous fibers that act as prebiotics. They slowly ferment in your large intestine, where they nourish healthy bacteria
Resistant starches also bulk up your bowel movements without making you feel bloated or gassy, and do not cause blood sugar spikes the way other starchy foods do
Unripe tropical fruits such as banana, papaya and mango contain digestive-resistant starch
High net-carb foods such as potatoes, rice, bread and pasta become more digestive-resistant when cooked, cooled and reheated
Compared to fresh bread — whether homemade or commercial — both freezing and toasting results in lower postprandial blood glucose measurements.
