Including the "fruit on the bottom" cup that's really dessert in disguise
Yogurt has a health glow, and plain yogurt earns it. But flavored cups are a different story. A single flavored yogurt—vanilla, strawberry, or the classic "fruit on the bottom"—can carry 15 to 25 grams of total sugar, often with 10 to 12 grams of that added on top of the natural lactose. The FDA uses a sweetened yogurt as its own teaching example on the Nutrition Facts label: 7 grams of added sugar plus 8 grams of naturally occurring sugar, for 15 grams total in a single serving.
Plain Greek yogurt, by contrast, has only about 4 to 7 grams of naturally occurring lactose and zero added sugar. That's a striking gap for what looks like the same food.
The swap gives you back control. Start with plain Greek yogurt and sweeten it yourself with a handful of fresh or frozen berries, and maybe a teaspoon of honey if you like. You'll still land far below a pre-sweetened cup, and you get the creamy, tangy texture without the dessert-level sugar.
