Choose a diet moderate in sugars

Sugars come in many forms

Sugars are carbohydrates. Dietary carbohydrates also include the complex carbohydrates starch and fiber. During digestion all carbohydrates except fiber break down into sugars. Sugars and starches occur naturally in many foods that also supply other nutrients. Examples of these foods include milk, fruits, some vegetables, breads, cereals, and grains. Americans eat sugars in many forms, and most people like their taste. Some sugars are used as natural preservatives, thickeners, and baking aids in foods; they are often added to foods during processing and preparation or when they are eaten. The body cannot tell the difference between naturally occurring and added sugars because they are identical chemically.

Sugars, health, and weight maintenance

Scientific evidence indicates that diets high in sugars do not cause hyperactivity or diabetes. The most common type of diabetes occurs in overweight adults. Avoiding sugars alone will not correct overweight. To lose weight reduce the total amount of calories from the food you eat and increase your level of physical activity (see here).

If you wish to maintain your weight when you eat less fat, replace the lost calories from fat with equal calories from fruits, vegetables, and grain products, found in the lower half of the Food Guide Pyramid. Some foods that contain a lot of sugars supply calories but few or no nutrients (box 12). These foods are located at the top of the Pyramid. For very active people with high calorie needs, sugars can be an additional source of energy. However, because maintaining a nutritious diet and a healthy weight is very important, sugars should be used in moderation by most healthy people and sparingly by people with low calorie needs. This guideline cautions about eating sugars in large amounts and about frequent snacks of foods and beverages containing sugars that supply unnecessary calories and few nutrients.

Sugar substitutes

Sugar substitutes such as sorbitol, saccharin, and aspartame are ingredients in many foods. Most sugar substitutes do not provide significant calories and therefore may be useful in the diets of people concerned about calorie intake. Foods containing sugar substitutes, however, may not always be lower in calories than similar products that contain sugars. Unless you reduce the total calories you eat, the use of sugar substitutes will not cause you to lose weight.

Sugars and dental caries

Both sugars and starches can promote tooth decay. The more often you eat foods that contain sugars and starches, and the longer these foods are in your mouth before you brush your teeth, the greater the risk for tooth decay. Thus, frequent eating of foods high in sugars and starches as between-meal snacks may be more harmful to your teeth than eating them at meals and then brushing. Regular daily dental hygiene, including brushing with a fluoride toothpaste and flossing, and an adequate intake of fluoride, preferably from fluoridated water, will help you prevent tooth decay (box 13).


Use sugars in moderation -- sparingly if your calorie needs are low. Avoid excessive snacking, brush with a fluoride toothpaste, and floss your teeth regularly. Read the Nutrition Facts Label on foods you buy. The food label lists the content of total carbohydrate and sugars, as well as calories.
