I know, I'm springing this quiz on you with no prior warning. You had no time to prepare or study and for that, I apologize. But that's the whole point of this little test, to determine just how off-the-cuff savvy you are about a few health matters. Are you ready? Here goes.

False: The term "fat free" means a food contains no fat:

The Food and Drug Administration (FDA) allows food companies to use this term on any product containing less than 0.5 grams per serving. This tiny trace of fat can also be present in products labeled as "no fat" and "zero fat." To locate items that really have no fat, look at the ingredient list to see whether any type of fat is listed. Be on the lookout for trans fat when you do your investigating. A product touted as "trans fat free" may still list partially hydrogenated oil as an ingredient. Know what this means? It actually contains minute amounts of trans fat. The amount may be insignificant -- unless you consume several servings or eat many products with these small amounts. It all adds up -- so watch your portion sizes.

False: Feed a cold, starve a fever.

When you have a cold or a fever, your body needs nourishing foods and fluids in order to heal. It's the only way to keep your immune system in fighting condition. If you don't have much of an appetite when you're under the weather, try foods that go down easily, like bananas, rice, applesauce, and dry toast (know as the BRAT diet). Drink plenty of water and decaffeinated beverages to replace lost fluids.

True: White sugar and brown sugar have the same nutritional value.

Both white and brown sugars come from either sugar beets or sugarcane. Both contain 4 calories per gram. But since brown sugar is denser than white sugar, a teaspoon weighs more and has slightly more calories -- 17 calories to white sugar's 16. Neither of these sugars have significant amounts of vitamins, minerals, or fiber.
