Total Sugar vs. Added Sugar: Clarifying the Daily Value
When looking at a Nutrition Facts label, you will see two categories related to sugar: “Total Sugars” and “Added Sugars.” The distinction between these two is critical for understanding dietary guidelines. Total Sugars include all sugars present in a food, both those that occur naturally (like in fruit and milk) and those that are added during processing. However, the U.S. Food and Drug Administration (FDA) has not set a Daily Value for total sugars because natural sugars come alongside beneficial nutrients like fiber, vitamins, and minerals. The Daily Value applies only to added sugars.
Added sugars are sweeteners and syrups that are added to foods and drinks during processing. Common examples include high-fructose corn syrup, honey, and table sugar. The FDA recommends a Daily Value for added sugars of 50 grams per day, which is based on a 2,000-calorie daily diet. For individuals with lower calorie needs, this amount would also be proportionally lower.
How to Read the Nutrition Facts Label
Reading the new Nutrition Facts label is straightforward once you know what to look for. On the label, under 'Total Carbohydrates', you will find the 'Total Sugars' line, and beneath that, the 'Includes Added Sugars' line with the corresponding grams and percentage Daily Value (%DV).
- Low Source: A food with 5% DV or less of added sugars per serving is considered a low source.
- High Source: A food with 20% DV or more of added sugars per serving is considered a high source.
Checking this percentage can help you quickly compare different products and make healthier choices. For instance, a sweetened yogurt might have a high percentage of added sugars, while a plain yogurt with fruit added at home would be much lower.
Recommendations from Health Organizations
While the FDA provides the 50g DV for added sugars, other health organizations offer more specific and often more conservative recommendations, particularly for vulnerable populations like children.
- American Heart Association (AHA): The AHA recommends even lower limits on added sugar. They suggest a maximum of 9 teaspoons (about 36 grams) per day for most men and 6 teaspoons (about 25 grams) per day for most women. For children, the recommendation is no more than 6 teaspoons (25 grams) per day.
- World Health Organization (WHO): The WHO provides guidelines on 'free sugars,' which are similar to added sugars but also include those found naturally in honey, syrups, and fruit juices. They strongly recommend limiting intake of free sugars to less than 10% of total energy intake and suggest a further reduction to below 5% for additional health benefits. For a 2,000-calorie diet, 5% is equivalent to roughly 25 grams or 6 teaspoons.
Comparison of Sugar Recommendations
| Feature | FDA Added Sugar DV | AHA Added Sugar Recommendations | WHO Free Sugar Recommendations |
|---|---|---|---|
| Basis | 2,000-calorie daily diet | General guidelines for men, women, and children | Total energy intake |
| Daily Limit | $\le$ 50 grams | Men: $\le$ 36g; Women: $\le$ 25g; Children: $\le$ 25g | Strongly recommend: $\lt$10% total calories; Conditionally recommend: $\lt$5% total calories |
| Included Sugars | Sugars added during processing, bottling, etc. | Sugars added to foods and drinks | All added sugars plus sugars in honey, syrups, and juices |
| Excludes | Sugars naturally occurring in milk, fruits, vegetables | Sugars naturally occurring in milk, fruits, vegetables | Sugars naturally occurring in milk, fruits, vegetables |
| For Extra Benefit | Not specified | Not specified | Further reduce to below 5% |
Health Risks of High Added Sugar Intake
Consuming too much added sugar has been linked to numerous negative health outcomes. Since added sugars provide 'empty calories' without significant nutrients, they can lead to increased calorie intake and weight gain, which is a major risk factor for chronic diseases.
- Weight Gain and Obesity: Excessive sugar, especially from sugary beverages, is a major contributor to rising obesity rates. Fructose, a type of sugar, can increase hunger and is metabolized by the liver, leading to fat storage.
- Heart Disease: High-sugar diets are associated with an increased risk of heart disease due to effects on blood pressure, triglycerides, and inflammation.
- Type 2 Diabetes: Excess sugar consumption can lead to weight gain and insulin resistance, significantly increasing the risk of developing type 2 diabetes.
- Fatty Liver Disease: The liver processes fructose, and too much can overload it, leading to nonalcoholic fatty liver disease (NAFLD).
- Dental Health: Sugar is a primary food source for bacteria in the mouth that produce acid, causing tooth decay and cavities.
- Cognitive Decline: High-sugar diets have been linked to memory impairment and an increased risk of dementia.
Practical Tips for Reducing Added Sugar
Reducing added sugar intake doesn't have to mean eliminating sweetness entirely from your diet. Here are some simple, practical steps to cut back:
- Rethink Your Drinks: Swap sugary drinks like soda, fruit punch, and sweetened teas for water, unsweetened sparkling water, or unsweetened tea.
- Check Condiments: Read labels on ketchup, barbecue sauce, and salad dressings, as they can contain surprisingly high amounts of added sugar. Choose low-sugar or no-sugar-added versions.
- Opt for Whole Foods: Choose whole fruits over fruit juices and add fresh berries to plain yogurt or oatmeal instead of buying pre-sweetened versions.
- Cook and Bake at Home: When you cook and bake, you have full control over the ingredients. Use spices like cinnamon or nutmeg for flavor or small amounts of natural sweeteners like fruit purée.
- Understand Sugar's Many Names: Added sugar can be hidden on ingredient lists under many different names, including corn syrup, dextrose, sucrose, and fruit juice concentrate. Look for these terms to identify hidden sugars.
Conclusion
The most important takeaway is that while there is no official Daily Value for total sugar, a clear 50-gram Daily Value is set for added sugars by the FDA for a 2,000-calorie diet. However, more stringent limits from organizations like the AHA and WHO suggest that lower intake is ideal for optimal health. By distinguishing between natural and added sugars, reading nutrition labels carefully, and making mindful food choices, you can effectively manage your sugar intake and reduce the associated health risks.
