• B. Providing essential vitamins and minerals
• C. Enhancing the flavor of meals
• D. Reducing the calorie content of foods

Answer: (A)

Fiber plays a crucial role in the diet primarily by aiding in digestion and preventing constipation. It is a type of carbohydrate that the body cannot digest, which helps to bulk up stool and promote regular bowel movements. Soluble fiber, found in foods like oats and fruits, can help to soften stool, making it easier to pass, while insoluble fiber, found in whole grains and vegetables, adds bulk and helps food move through the digestive tract.

In addition to promoting regularity, a high-fiber diet is associated with various health benefits, including a lower risk of developing conditions such as heart disease, type 2 diabetes, and certain cancers, due to its effects on cholesterol levels and blood sugar control. Therefore, its primary function in the diet revolves around enhancing digestive health and preventing issues like constipation, making it a vital component of a balanced diet.
