Myths and Truths about Candy

MYTH: Candy contributes to a large percentage of the fat and sugar in the American diet.
TRUTH: In fact, less than two percent of the fat and ten percent of the sugar in our diets are supplied by candy. Most of the fat actually comes from the high-fat animal products we eat. The main sources of sugar in America's diets are sugary beverages, baked goods and frozen desserts.

MYTH: Foods high in saturated fats raise cholesterol levels.
TRUTH: Contrary to popular belief, not all types of saturated fats raise blood cholesterol levels. Stearic acid, the primary saturated fatty acid found in chocolate, has been shown to have a neutral effect on blood cholesterol levels.

MYTH: An ounce of milk chocolate contains about as much caffeine as a cup of coffee.
TRUTH: Actually, a one-ounce piece of milk chocolate contains about the same amount of caffeine as a cup of decaffeinated coffee. There is an average of 6 mg. of caffeine in both an ounce of milk chocolate and a cup of decaf, while a cup of regular coffee contains between 150 and 655 mg. of caffeine.

MYTH: The sugar in candy causes hyperactivity in children.
TRUTH: Sugar does not cause hyperactivity in children, despite wide-spread belief to the contrary. Recent studies conducted at Vanderbilt University and the University of Iowa College of Medicine found no evidence that sugar has an adverse effect on children's behavior.

MYTH: Candies like jelly beans, gum drops or hard candies are high in calories.
TRUTH: Not at all. One butterscotch disc has only 20 calories. Eight gum drops or eight jelly beans (the equivalent of one ounce) contain 115 calories. Even better, most of these candies are fat- and cholesterol-free, making them a healthier treat than many people realize.

MYTH: Chocolate is addictive.
TRUTH: Although it's true that many people love the taste of chocolate, it is not an addictive food. An addiction is a serious medical condition with specific physical and psychological symptoms. However, the desire for sweet tasting food is a strong biological drive, and it can be satisfied by eating any naturally sweet food or product made with sugar.

MYTH: Candy is responsible for most tooth decay.
TRUTH: Not so. Any food containing fermentable carbohydrates, such as starches or sugars, can contribute to tooth decay. It all depends on how often we eat and drink these foods and how long they remain in our mouths. Good dental hygiene and regular fluoride treatments are the best ways to prevent cavities.
