The formula
Worked example
Using the default values shown in the calculator:
| Sugar (g) | 35 |
|---|---|
| Daily calories | 2000 |
- 35 g ÷ 4.2 = 8.3 teaspoons.
- That is 140 kcal, or 7.0% of a 2,000 kcal day.
- The WHO 10% limit is 50 g and the 5% target 25 g.
Result:
| Teaspoons (4.2 g each) | 8.3 |
|---|---|
| Calories from sugar | 140 |
| Share of daily calories | 7.0% |
| WHO limit at 10% of calories (g) | 50 |
| WHO conditional target at 5% (g) | 25 |
