Gut health benefits

Resistant starch

According to Dr Salhab, when sweet potatoes cool, some of their starch is converted into resistant starch. He explains, “That resistant starch makes it farther down into your gut, where your good gut bacteria feed on it. It can also help add bulk to your stool and support more regular bowel movements.”

Fibre

The gastroenterologist also points out that sweet potatoes are rich in soluble and insoluble fibre, making them beneficial for gut health. He highlights, “Sweet potatoes also contain soluble and insoluble fibre, which help soften stool, add bulk, and keep things moving.”

Mannitol

Sweet potatoes also naturally contain mannitol, a sugar alcohol that can help soften stools and promote bowel movements, potentially providing relief from constipation. Dr Salhab notes, “They naturally contain mannitol, a sugar alcohol that can pull water into the intestines and may help soften stool and stimulate a bowel movement.”
