Answer to Question 2
Many people do not like fruits, vegetables, or whole grains. Perhaps, they have not had many of these foods as part of their diet or they do not know how to prepare these foods. They also could be under the impression that they have to eat a very large amount of these foods to obtain their daily recommended amounts of fiber.
Many people do not know the current nutritional guidelines for daily fiber intake. They might not know where to look on a food label for the daily fiber recommendation. The amount of fiber for a particular food item is listed on the nutrition facts label but the consumer may not understand how to interpret the daily value of that particular product's contribution of fiber.
If people live in a city, they might not have a supermarket with fresh produce near them. They might not have the means to properly store or cook produce and so they might eat fast or processed foods which contain very little fiber.
