Total Sugars vs. Added Sugars: Why the Distinction Matters
When you look at a nutrition label, you'll see a line for “Total Sugars” but no percentage Daily Value (%DV) next to it. The updated FDA labels do, however, include a line for “Added Sugars” with a %DV. This difference exists because the source of sugar significantly impacts its nutritional value and health effects.
The Source of the Sweetness
Natural sugars, found in foods like fruits (fructose) and milk (lactose), are consumed as part of whole foods that also provide fiber, vitamins, and minerals. These components help regulate how the body processes the sugar. Health organizations haven't set a specific daily limit for total sugar intake because natural sugars from whole foods are not considered a public health concern within a balanced diet.
Added sugars are different. They are sweeteners added to foods and drinks during processing, such as high-fructose corn syrup or honey. These add calories without significant nutrients, often called "empty calories".
The Health Impact of Added Sugars
High intake of added sugars is linked to various health problems. The Dietary Guidelines for Americans suggest limiting added sugars to less than 10% of daily calories. For a 2,000-calorie diet, this is about 50 grams, which is the basis for the %DV for added sugars on labels. The American Heart Association recommends even lower limits for heart health.
Too many added sugars can contribute to:
- Weight Gain: Especially from sugary drinks.
- Increased Risk of Chronic Diseases: Including heart disease, type 2 diabetes, and fatty liver disease.
- Nutrient Displacement: Making it harder to get essential nutrients.
- Insulin Resistance: A risk factor for type 2 diabetes.
Comparison of Total Sugar vs. Added Sugar
| Feature | Total Sugars | Added Sugars |
|---|---|---|
| Source | Includes both naturally occurring and added sugars. | Sugars and syrups added during processing or preparation. |
| Nutritional Context | Comes with naturally occurring fiber, vitamins, and minerals in whole foods like fruit. | Provides "empty calories" with little to no nutritional value. |
| Health Impact | Sugar from whole foods is digested slower and does not pose the same health risks as added sugars. | Excess intake is linked to obesity, diabetes, and heart disease. |
| Labeling | Grams listed, but no % Daily Value (%DV) is assigned. | Grams listed with a corresponding %DV to indicate daily contribution. |
How to Interpret the Nutrition Label
Focusing on the “Added Sugars” on the nutrition label is key. Here's how to use it:
- Check the %DV for Added Sugars: A %DV of 5% or less per serving is low, while 20% or more is high.
- Compare Products: Use the %DV to choose options with less added sugar.
- Read Ingredients: Look for various names for added sugars like corn syrup or dextrose. Ingredients are listed by amount, with the highest first.
- Make Swaps: Choose whole fruits over juices and unsweetened drinks over sugary ones.
Conclusion
The lack of a Daily Value for total sugars highlights the important distinction between natural and added sugars in food. By focusing on the %DV for added sugars, consumers can make healthier choices and reduce their intake of sugars linked to negative health outcomes. Prioritizing whole foods naturally low in added sugars is a key strategy for a healthier diet. You can find more comprehensive dietary guidelines at DietaryGuidelines.gov.
