The true statement is: "Most Americans do not consume enough dietary fiber."

Here's why:

1. Most forms of fiber are not comprised of fructose molecules bonded together. Fiber is a type of carbohydrate that the body can’t digest. While most carbs break down into sugar molecules, fiber cannot be broken down into sugar molecules, and instead it passes through the body undigested.

2. Scientists do not classify forms of fiber according to their solubility in oil. They classify fiber based on its solubility in water, into soluble fiber (which dissolves in water) and insoluble fiber (which does not).

3. Dietary fiber does not include the stringy material found in tough, overcooked meat. Dietary fiber is found in plant foods like fruits, vegetables, and grains. Meat does not contain dietary fiber.

4. Most Americans do not consume enough dietary fiber. According to the American Heart Association, the daily value for fiber is 25 grams per day on a 2,000-calorie diet for adults. However, Americans only consume an average of 15 grams a day.
