When we eat more sugar than the amount needed for energy, the body converts the sugar to a storage form. This stored form is used to meet energy needs and maintain blood sugar levels within a narrow range. Excess sugar is converted to fat. Consumption of sucrose in the form of table sugar has not changed significantly over the past century. However, the use of sweeteners deried from corn syrup has risen dramatically, particularly in soft drinks.
Some sugars serve as natural preservatives, thickeners, and baking aid in foods.
Sugars and most foods that contain them in large amounts supply calories but are limited in essentail nutrients. Therefore, they should be used in moderation by most healthy people and sparingly by people with low calorie needs. Carbohydrates such as sugars and starches can contribute to the development of tooth decay. Complex carbohydrates are found in fruits, vegetables, whole grains, and legumes. In addition to calories, these foods provide vitamins, minerals and fiber in your diet.
