How Long Does It Take to Digest Food

Fiber

"The fiber content of a food impacts how quickly it's digested," explains Burgess. "Foods higher in soluble fiber form a gel-like substance in the stomach, which slows down the digestive process. In contrast, foods high in insoluble fiber speed up the digestive process because they quickly pass unabsorbed into the large intestine, where they add bulk to stool." Both types of fiber are important to consume regularly, explains Ferira.
