Answer to Question 1

ANS: A
Monounsaturated fats decrease low-density lipoprotein (LDL) and increase high-density lipoprotein (HDL) and are considered to be cardioprotective. Polyunsaturated fats also lower LDL and raise HDL but are not considered to be cardioprotective. Saturated fats raise both LDL and HDL and are thought to increase atherosclerotic plaque formation in the arteries. Trans fats may induce more heart disease than saturated fats because in addition to raising LDL cholesterol, trans fats decrease HDL cholesterol and increase triglycerides, as well as another undesirable blood fat, lipoprotein.

Answer to Question 2

ANS: A
Vegetables and fruits that are orange (sweet potatoes, cantaloupe, carrots) are concentrated with carotene and are a good source of vitamin A. Apples are a good source of soluble and insoluble fiber. Bananas are a good source of fiber, potassium, and vitamin C. Whole grain bread is a good source of vitamin E and fiber.
