- Sucrose (common table sugar)
- Lactose (milk sugar)
- Maltose (product of starch digestion)
- Provide sweet flavor when added to food.
- Maintain freshness and food quality.
- Act as a preservative in jams and jellies.
- Enhance flavor in processed meats.
- Provide fermentation for breads and pickles.
- Add bulk to ice cream and body to carbonated sodas.
- Sucrose is made from a low-sugar beet juice or sugar cane. It is made up of about half glucose and half fructose. Sucrose includes raw sugar, granulated sugar, brown sugar, confectioner's sugar, and turbinado sugar.
- Raw sugar is granulated, solid, or coarse. It is brown in color. Raw sugar is the solid part left when the liquid from the juice of the sugar cane evaporates.
- Brown sugar is made from sugar crystals that come from molasses syrup.
- Confectioner's sugar (also known as powdered sugar) is finely ground sucrose.
- Turbinado sugar is unrefined sugar made from sugar cane juice.
- Raw and brown sugars are no healthier than granulated white sugar.
- Fructose (fruit sugar) is the naturally occurring sugar in all fruits. It is also called levulose, or fruit sugar.
- Honey is a combination of fructose, glucose, and water. It is produced by bees.
- High fructose corn syrup (HFCS) and corn syrup are made from corn. Sugar and HFCS have almost the same level of sweetness. HFCS is often used in soft drinks, baked goods, and some canned products.
- Sugar alcohols include mannitol, sorbitol, and xylitol.
- These sweeteners are used as an ingredient in many food products that are labeled "sugar-free", "diabetic", or "low carb". These sweeteners are absorbed by the body at a much slower rate than sugar. They also have about half the calories of sugar. They should not be confused with sugar substitutes that are calorie free. Sugar alcohol may cause stomach cramps and diarrhea in some people.
- Erythritol is a naturally occurring sugar alcohol found in fruit and fermented foods. It is 60 to 70% as sweet as table sugar, but has fewer calories. Also, it does not result in as much of a rise in blood sugar after meals or cause tooth decay. Unlike other sugar alcohols, it does not cause stomach upset.
- Dextrose is glucose combined with water.
- Invert sugar is used in a liquid form to help keep candies and baked items sweet.
- Agave nectar is a highly processed type of sugar from the Agave tequiliana (tequila) plant. Agave nectar is about 1 1/2 times sweeter than regular sugar. It has about 60 calories per tablespoon, compared to 40 calories for the same amount of table sugar. Agave nectar is not healthier than honey, sugar, HFCS, or any other type of sweetener.
- Glucose is found in fruits in small amounts. It is also a syrup made from corn starch.
- Lactose (milk sugar) is the carbohydrate that is in milk. It is made up of glucose and galactose.
- Maltose (malt sugar) is produced during fermentation. It is found in beer and breads.
- Maple sugar comes from the sap of maple trees. It is made up of sucrose, fructose, and glucose.
- Molasses is taken from the residue of sugar cane processing.
- Women should get no more than 100 calories per day from sugar (about 6 teaspoons of sugar).
- Men should get no more than 150 calories per day from sugar (about 9 teaspoons of sugar).
- Drink water instead of regular soda, "vitamin-type" water, sports drinks, coffee drinks, and energy drinks.
- Eat less candy and sweet desserts such as ice cream, cookies, and cakes.
- Sugars affect blood glucose control the same as other carbohydrates when eaten at meals or snacks. It is still a good idea to limit foods and drinks with sugar, and to check your blood sugar levels carefully.
- Foods that contain sugar alcohols may have fewer calories, but be sure to read the labels for the carbohydrate content of these foods. Also, check your blood sugar levels.
The term sugar is used to describe a wide range of compounds that vary in sweetness. Common sugars include:
Sugars are found naturally in milk products (lactose) and fruits (fructose). Most of the sugar in the American diet is from sugars added in food products.
Sweeteners do the following things:
Foods containing natural sugars (such as fruit) also include vitamins, minerals, and fiber. Many foods with added sugars often add calories without nutrients. These foods and drinks are often called "empty" calories.
Most people know that there is a lot of added sugar in soda. However, popular "vitamin-type" waters, sports drinks, coffee drinks, and energy drinks also contain a lot of added sugar.
Some sweeteners are made by processing sugar compounds. Others occur naturally.
Sucrose (table sugar):
Other commonly used sugars:
Other types of natural sugars:
Sugar provides calories and no other nutrients. Sugar and other sweeteners with calories can lead to tooth decay.
Sugar alcohols such as sorbitol, mannitol, and xylitol may cause stomach cramps and diarrhea when eaten in large amounts.
Sugar is on the U.S. Food and Drug Administration's (FDA) list of safe foods. It contains 16 calories per teaspoon and can be used in moderation.
The American Heart Association (AHA) recommends limiting the amount of added sugars in your diet. The recommendation extends to all types of added sugars.
The Dietary Guidelines for Americans also recommends limiting added sugars to no more than 10% of your calories per day. Some ways to reduce your intake of added sugars include:
There is currently no daily recommendation for the naturally occurring sugars found in milk and fruit products, but too much of any sugar can have negative effects on your health. It is important to have a balanced diet.
The American Diabetes Association nutrition guidelines state that you do not need to avoid all sugar and foods with sugar if you have diabetes. You can eat limited amounts of these foods in place of other carbohydrates.
