Broad bean

Beans contain complex carbohydrates known as oligosaccharides, especially raffinose and stachyose. The human body cannot completely break down these carbohydrates because we lack the enzyme alpha-galactosidase. This inability to digest these carbohydrates can eventually lead to gas and bloating as they ferment in the large intestine.

Fiber Content of Beans

Beans are rich in fiber, which is good for digestive health. It helps regulate bowel movements and prevent constipation. However, the high fiber content can also contribute to the initial discomfort some people may experience if they are not accustomed to a fiber-rich diet.
