Out of yogurt or Coke®, the sugar content in yogurt — particularly varieties with fruit or other flavorings — is often higher than the sugar content in Coke®. A standard 12-ounce (475-milliliter) can of Coca-Cola® contains 39 grams of sugar. The same amount of yogurt — usually two packaged single-serving containers of yogurt — that contains fruit or other flavorings can contain more than 40 grams of sugar. Plain yogurt has significantly less sugar than its fruit-flavored counterparts, at about 14 grams per 12 ounces (475 mL), with most of those calories occurring naturally and not added.
