Does fiber and roughage mean the same thing?

Fiber and roughage are not exactly the same thing, although they are related concepts.

Dietary fiber is a type of carbohydrate that the human body cannot digest. It is found in plant foods such as fruits, vegetables, whole grains, and legumes. Fiber is important for good digestive health and can help to lower cholesterol and blood sugar levels.

Roughage is a term used to describe plant foods that are high in fiber. These foods can be challenging to chew and digest, but they are beneficial for digestive health and can help to keep you feeling full.

So, while fiber and roughage are both found in plant foods, fiber is a specific type of carbohydrate, while roughage is a general term used to describe plant foods that are high in fiber.
