How to read a food label.

You stare at them as you munch your breakfast cereal. You rip through them to grab a handful of chips or a row of Oreos. But have you ever actually read a food label? Thanks to a 1993 law, these labels are more helpful and truthful than ever before, providing crucial information that will tell you whether a food is healthy fuel filled with nutrients or a decadent nosh laden with fat and sugar. Become the master of your diet. Read those labels.

The federal government now has strict guidelines for what food manufacturers must say on their labels. Food companies can get into trouble for lying. The key word here is "fact." For example, "low saturated fat" on the label means 1 gram or less of fat per serving.

Serving Size: is supposed to reflect how much of this food a normal hungry person would eat in one sitting. Of course, few of us can restrict ourselves to 13 potato chips or 1/2 cup of ice cream. So look closely at the serving size.

Calories: Our bodies need energy to fuel cells and tissues. We get that energy from the foods we eat. The amount of energy stored in a given food is measured in calories. The typical teenaged girl needs about 2,200 calories a day; the average boy, about 2,800. The label is geared to a 2,000-calorie diet. Look for foods with high % Daily Values for dietary fiber, vitamins and minerals.

Sodium: A main ingredient in salt, sodium controls the amount of fluids in our bodies. Too much sodium causes our bodies to retain fluids, which can lead to high blood pressure, strokes, and heart attacks. Most nutritionists recommend eating no more than 2,400 to 3,000 milligrams of sodium per day.

% Daily Value: This column gives you an idea of how one serving of a food fits into an adult's daily diet. This information helps you keep tabs on substances, like fat and sodium, that you should limit. It also helps you see how a food contributes to daily requirements of important vitamins, minerals, and other nutrients.

Fat: This substance, which looks globular and yellowish on its own, occurs naturally in meats, dairy products, and most oils. Eating too many fatty foods--like french fries, red meat, whole milk, cheese, and rich desserts--can lead to health problems. Teenage girls should consume less than 65 grams of fat a day; boys should consume 80 grams or less.

Saturated Fat: This is listed separately on food labels because it's particularly unhealthy. Saturated fats include butter, meat fat, Crisco, and palm and coconut oils. Unsaturated fats, which are easier on the body, include olive and canola oils.

Cholesterol: This white, waxy substance occurs naturally in our bodies and travels through our blood. Eating too many saturated fats causes our bodies to produce too much cholesterol, which can clog arteries and eventually cause heart attacks and strokes.
