Yogurt has long been heralded as a top health food. Greek yogurt in particular is high in protein, low in sugar, and comes in low- and non-fat varieties. Because of this, many have come to assume that any type of yogurt will provide these nutritional benefits. The problem is that Greek yogurt only makes up 15% of yogurt volume sales, meaning that most of us aren’t choosing the healthier alternatives. Instead, we’re opting for the flavored, sugary products made popular by yogurt giants such as Yoplait (GIS). Although Yoplait had advertised that their light yogurt can help you lose "5 pounds in 2 weeks!," the fact of the matter is even the light varieties contain around 14 grams of sugar per serving. Choose a regular flavored version, and you can easily double that amount, adding an additional four teaspoons or more of sugar. One serving of plain, non-fat Fage yogurt contains 18 grams of protein and only five grams of sugar; the same serving of strawberry Yoplait has a mere five grams of protein while packing a sickly sweet 26 grams of sugar. Judging by recent yogurt sales, however, consumers are starting to catch on: This past quarter, Yoplait sales slipped below popular Greek yogurt brands Fage and Chobani.
