What term is used for coarse food high in fiber but low in nutrients?

1. Refrigerant

2. Roughage

3. Rh factor

4. Regeneration

The correct answer is: Roughage

The term used for coarse food that is high in fiber but low in nutrients is "roughage." Roughage typically includes parts of plant foods that the body cannot digest, such as the skins and stems of fruits and vegetables, and whole grains. It is an important component of a balanced diet since it aids in digestion and helps to prevent constipation by adding bulk to the stool. Roughage is particularly beneficial as it can help you feel full, which may assist in weight management, even though it doesn't provide a lot of calories or essential nutrients. Foods high in roughage can encourage healthy bowel movements and contribute to overall digestive health. The other terms provided do not apply to the definition of coarse food high in fiber. For instance, refrigerant refers to substances used to cool or refrigerate, the Rh factor is associated with blood types, and regeneration pertains to the process of renewal or regrowth in biological contexts. Each of these terms belongs to different categories of knowledge and does not relate to dietary fiber or nutrition, clarifying why they do not fit the definition provided in the question.
