About the Added Sugar Intake Calculator
This calculator compares your added sugar intake against two widely cited benchmarks: the American Heart Association (AHA) daily limit and the USDA Dietary Guidelines for Americans (DGA) 10%-of-calories rule. It is intended for educational and dietary-planning use. It does not diagnose or treat any condition, and it does not account for individual medical needs such as diabetes management, which should be discussed with a doctor or registered dietitian.
How the limits are calculated
The AHA recommends adults cap added sugar at 36 grams (9 teaspoons) per day for men and 25 grams (6 teaspoons) per day for women, figures based on a 2,000-calorie reference diet. The same 25-gram limit is commonly used for children ages 2 to 18. Separately, the DGA recommends keeping added sugar under 10% of total daily calories. Because sugar provides about 4 calories per gram, that gram limit is calculated as (daily calories × 0.10) ÷ 4. This calculator converts grams to teaspoons using 4.2 grams per level teaspoon of granulated sugar, and estimates the percentage of your daily calories coming from added sugar as (grams entered × 4 ÷ daily calories) × 100.
Interpreting your results
- The AHA limit is intentionally tighter than the DGA 10% rule, so it is possible to be within the DGA guideline while still exceeding the AHA recommendation.
- "Added sugar" means sugar and syrups added during processing or preparation — it excludes sugars naturally occurring in fruit, vegetables, and plain dairy. Check the "Added Sugars" line on Nutrition Facts labels rather than "Total Sugars" when estimating your daily grams.
- These are population-level guidelines, not individualized medical targets. People managing diabetes, triglycerides, or other conditions should follow guidance from their doctor or registered dietitian, which may differ from the general limits used here.
