Important Points from this Chapter

Resistant starch is starch that normally you can digest but becomes resistant to this process. You will find it in pasta, some vegetables, or potatoes allowed to cool after they have been cooked. Unripe fruits, sourdough bread, and raw cornstarch are also sources of resistant starch. They do not break down well in your GI tract and mimic regular dietary fiber.

A few types of sugar are indigestible to humans but not by the bacteria in your gut. People who are lactose intolerant will consume indigestible sugar if they drink milk containing lactose. Raffinose, which is a type of sugar in cabbage and broccoli, is also not easily digested by humans alone. Sorbitol can be found in apples and pears. You do not digest sorbitol easily either. As with other foods digested by the gut bacteria, flatulence can result from eating them.
