- Add anything extra with the custom grams box, then watch the bar against your WHO limit.
Note: this tracks added sugar (soda, sweets, sweetened tea), not the natural sugar in whole fruit or plain milk. Values are averages — labels vary by brand. For diabetes or other health conditions, follow your doctor, not this calculator.
