A Nutrition Facts panel (NFP) for cane sugar, coconut sugar, maple syrup, honey, agave syrup, and other sugars sold as single ingredients reflect zero grams of added sugar. When those sugars are an added ingredient to a food product, they are considered added sugar on the NFP.
For example, an NFP for bottled, 100 percent maple syrup would reflect zero grams of added sugar. Granola sweetened with maple syrup must claim the maple syrup as added sugar.
A bit confusing, but remember sugar sold as a single ingredient has no added sugar. A multi-ingredient product with sugar has added sugar.
