Answer:
C) Increases in daily fiber intake should be gradual.
Explanation:
Fiber is the indigestible part of plants and carbohydrates. Beans, peas and lentils are some sources of fiber.
Fiber is best obtained through dried peas and beans and not from pills and the optimal amount of fiber varies with gender, age and pregnancy so there is no fixed diet for fiber and 25 g fiber a day is recommended for adult women and 38 g for adult men.
Increases in daily fiber intake should be gradual because a high fiber diet helps to prevent diseases like heart diseases, diabetes, constipation, and colon cancer. It also smoothens the digestive system and lowers the cholrestrol.
Hence, the correct answer is "C) Increases in daily fiber intake should be gradual."
