Feeling pretty good about cutting out pasta, potatoes, and other starchy fare from your diet? Not so fast: Research shows you may actually be missing out on a slew of health benefits, including a sleeker physique. That’s because all high-carb foods are not created equal.

Resistant starch is a type of fiber found in certain plant foods, including beans, corn, and bread. As the name implies, this starch “resists” digestion in the small intestine, which prevents your body from absorbing the calories it contains. By the time resistant starch makes its way to the colon, specific types of good bacteria feed on it to produce short-chain fatty acids, including butyrate (more on that below).
