6. Explain why a high fiber diet is important, and tell how this can be obtained.

Fiber promotes the wavelike contractions that keep food moving through the intestine. Also, high-fiber foods expand the inside walls of the colon. This eases the passage of waste. Fibrous substances pass through the intestine undigested. They also absorb many times their weight in water, resulting in softer, bulkier stools. Insoluble fiber is found in wheat, rye, bran, and other grains. It is also the fiber found in most vegetables. See [1]

10. What is the difference between saturated and unsaturated fats? Which is the most healthful, and why?

Saturated fats and trans fatty acids are the kinds of fats most likely to cause heart disease. Saturated fats are found mainly in animal products (eggs, butter, cheese, whole milk, and whole milk products), and in coconut, palm, and palm kernel oil. Trans fatty acids appear in foods containing hydrogenated fats like margarine and crackers. To reduce the risk of heart disease, replace saturated fats with unsaturated fats like canola oil, olive oil, flax seed oil, nuts, avocado, soy products, and nut butters. Choose margarine, cookies, crackers, and snack foods that do not contain hydro-genated fats (read the label). See [3]
