Understanding the Recommended Daily Sugar Intake
Health experts worldwide agree that most people consume too much added sugar, which can lead to a range of health problems, including weight gain, type 2 diabetes, heart disease, and tooth decay. Organizations such as the American Heart Association (AHA) and the World Health Organization (WHO) have published specific guidelines to help people moderate their intake of added and free sugars.
American Heart Association (AHA) Guidelines
For added sugars, the AHA provides stricter limits than many other organizations. Their recommendations are focused on protecting heart health and are based on a typical daily caloric intake:
- For most adult women: No more than 100 calories per day from added sugars, which is approximately 6 teaspoons or 25 grams.
- For most adult men: No more than 150 calories per day from added sugars, which is approximately 9 teaspoons or 36 grams.
- For children and adolescents (ages 2-18): Less than 25 grams (about 6 teaspoons) of added sugar per day.
- For children under 2: The AHA recommends avoiding any added sugars altogether.
World Health Organization (WHO) Guidelines
The WHO recommendations focus on "free sugars," which include added sugars as well as sugars naturally present in honey, syrups, fruit juices, and fruit juice concentrates. This does not include sugars found in whole fruits and vegetables.
- Strong recommendation: The WHO recommends that intake of free sugars should be reduced to less than 10% of total daily energy intake. For a 2,000-calorie diet, this equates to a maximum of 50 grams (about 12 teaspoons) per day.
- Conditional recommendation: For additional health benefits, the WHO suggests a further reduction to below 5% of total energy intake, or about 25 grams (around 6 teaspoons) per day.
Added vs. Natural Sugars: What's the Difference?
It is critical to understand the distinction between added and natural sugars, as they have different effects on the body. This is why guidelines often focus specifically on added sugars.
Added sugars are sugars and syrups put into foods during processing or preparation. They provide energy but offer little to no nutritional value, which is why they are often called "empty calories". Common sources include soda, candy, cookies, and processed foods.
Natural sugars are those naturally found within whole, unprocessed foods like fruit (fructose) and milk (lactose). These foods also contain fiber, vitamins, and minerals. The fiber in whole fruits, for example, slows the absorption of sugar, providing a more sustained energy release. Because they are part of a nutritious whole food package, experts do not recommend limiting natural sugars from fruits and vegetables.
Comparison Table: Added vs. Total Sugar
| Feature | Added Sugars | Total Sugars |
|---|---|---|
| Definition | Sugars and syrups added during food processing or preparation. | The sum of both added sugars and naturally occurring sugars in a food or drink. |
| Nutritional Value | Provide calories but little to no nutritional benefits. | Can be part of a nutritious food package (e.g., fruit) or from empty-calorie sources (e.g., soda). |
| Absorption Rate | Absorbed quickly by the body, causing rapid blood sugar spikes. | Absorption rate varies depending on the food source. Whole foods with fiber lead to slower absorption. |
| Recommended Limit | The focus of daily limits recommended by health organizations like the AHA and WHO. | There is no Daily Value for total sugars, as the source is more important than the total amount. |
Practical Strategies for Reducing Sugar Intake
Given the low recommended daily limits for added sugars, it's clear that most people need to actively reduce their intake. Here are some actionable steps you can take:
- Become a label detective: Look for the "Added Sugars" line on the Nutrition Facts label. The FDA requires this information to be listed separately from total sugars. A product with 5% Daily Value or less is considered low, while 20% or more is high. Also, be wary of ingredient lists where sugar appears near the top, or is disguised under names like high-fructose corn syrup, dextrose, or maltose.
- Rethink your drink: Sugary beverages are the largest source of added sugar for many people. Swapping soda, fruit drinks, and sweetened teas for water, unsweetened sparkling water, or unsweetened tea can drastically reduce your intake.
- Embrace whole foods: Choose whole fruits over fruit juices and plain yogurt over sweetened versions. Whole foods come with fiber and other nutrients that mitigate the sugar's impact on your body.
- Cook at home more often: This gives you full control over the ingredients, including how much sugar goes into your meals. Many pre-packaged sauces, dressings, and baked goods are packed with hidden sugars.
- Prioritize protein and fiber: Eating meals that are rich in protein and fiber helps you feel full and stable, reducing the likelihood of intense sugar cravings. Foods like eggs, nuts, and whole grains are excellent choices.
- Wean yourself off sweetness slowly: If you are accustomed to very sweet foods, try to reduce the amount of sugar you add to coffee or cereal gradually. Your taste buds will adjust over time.
Conclusion
Navigating daily sugar intake requires a mindful approach to what you eat and drink. By focusing on limiting added and free sugars to stay within expert recommendations—no more than 25 grams (6 teaspoons) for women and 36 grams (9 teaspoons) for men—you can significantly improve your long-term health. Prioritizing whole foods, reading nutrition labels carefully, and making simple swaps can empower you to gain better control over your sugar consumption and its impact on your well-being.
