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