What specific group of complex sugars is identified as the primary compound responsible for causing gas after bean consumption?

Answer

Oligosaccharides

The infamous digestive side effect of bloating and gas associated with eating beans stems from specific complex sugars known as oligosaccharides. These compounds are largely indigestible by human enzymes in the upper digestive tract. When they reach the large intestine, the beneficial gut bacteria ferment them, producing gas as a byproduct of this process. Understanding this mechanism is key to employing preparation strategies that minimize their presence, such as proper soaking and thorough cooking, to improve digestive compatibility.
