Why the sugar line doesn’t tell you this
Sugar alcohols and zero calorie sweeteners don’t count toward the “sugars” line on a US nutrition panel, so a bar can print 0g sugar while using several sweeteners. The only reliable place to check is the ingredient statement, which is what this table is built from. Click any flavour for its full verbatim ingredient list and nutrition panel.
