Fruit Sugar Calculator

Natural sugars per portion across common fruits — with why whole fruit doesn't count against the WHO line.

Natural sugars (g)
Calories (kcal)
Fibre (g)

WHO's sugar limits explicitly exclude whole fruit — the fibre matrix slows absorption and the package brings potassium, vitamins and polyphenols; cohort data ties whole fruit to *lower* diabetes risk while juice ties to higher. Even mango, the 'sugar bomb', is innocent at a cup; the trouble starts when fruit becomes juice and the fibre stays in the press.

Formula

USDA per-portion values × portions
Sources: USDA FoodData Central — fruits; Muraki I et al., BMJ 2013 — fruit vs juice and diabetes risk
