WHO free sugars include sugars added by manufacturers, cooks or consumers, honey, syrups, fruit juices and juice concentrates. They exclude sugars in fresh fruit and vegetables and those naturally present in milk. FDA added sugars are sugars added during processing or packaged as sweeteners, including honey and syrups and sugars from certain juice-concentrate uses. WHO free sugars additionally include sugars naturally present in fruit juice. These definitions cannot be substituted for each other.

Added Sugars and WHO Free Sugars
FDA added sugars are sugars added during processing or packaged as sweeteners, including honey and syrups and sugars from certain juice-concentrate uses. WHO free sugars additionally include sugars naturally present in fruit juice. These definitions cannot be substituted for each other.
Educational scenario: enter total energy and free sugars for the same day. This calculator does not estimate energy needs or establish a personal safe dose.
WHO free sugars include sugars added by manufacturers, cooks or consumers, honey, syrups, fruit juices and juice concentrates. They exclude sugars in fresh fruit and vegetables and those naturally present in milk.
On the US FDA Nutrition Facts label, “Total Sugars” includes naturally occurring and added sugars; “Includes … Added Sugars” is a separate line. Labels in other regions may show only total sugars. The ingredient list can identify sugar, honey or syrups, but does not always reveal grams of WHO free sugars. Fruit juice can contain free sugars without an added-sugars entry.
WHO Free-Sugar Guidance
WHO 2015: less than 10% of energy from free sugars — strong recommendation. The displayed equivalent is the mathematical boundary, not an amount recommended to consume.
WHO 2015: less than 5% — conditional recommendation for additional dental-caries benefits.
Calculation: grams × 4 kcal/g ÷ total energy × 100. General-population guidance for adults and children does not validate an individual plan for children, pregnancy or medical conditions.
Why are 50 g and 25 g shown at 2,000 kcal? They are 10% and 5% boundaries using 4 kcal/g. WHO says below those percentages; equality is not “below.” At 40 g and 2,000 kcal the share is 8%. The form accepts zero grams, requires a positive energy total, and never derives calories from age, sex or activity.

Health Effects of Excessive Sugar
The WHO 2015 guideline concerns unhealthy weight gain and dental caries. Its additional recommendation below 5% is conditional, based on limited evidence about dental caries. This arithmetic does not predict diabetes, cardiovascular disease, cancer or an individual health outcome.
Calculation: grams × 4 kcal/g ÷ total energy × 100. General-population guidance for adults and children does not validate an individual plan for children, pregnancy or medical conditions.

Tips for Reducing Added Sugar
Compare the same serving sizes and multiply by the number of servings actually consumed. Try water or unsweetened drinks, plain yogurt with fresh fruit, and less sugar or syrup in recipes. Record the amount consumed across the whole day. These are practical ways to change the entered scenario, not a prescribed diet.
Check sweetened drinks, flavored yogurt, cereals, sauces, desserts and packaged snacks. Quantities differ by brand and portion; use the actual label rather than a fixed food-equivalent table. Honey, syrup and 100% fruit juice still count as WHO free sugars even without added table sugar.
