Wanted: low sugar yogurt.
I am surprised that no one has called out yogurt makers for the high sugar contents of their products. Coke and other sugary drinks, sure. But yogurt? The lowest sugar yogurt I can find has 9 gms of sugar. Some are above 20 gms of sugar, esp. the low fat ones. They make up for the low fat with high sugar.
Dannon has a carb control brand yogurt (2 gms), but it's almost impossible to find on grocer shelves. I have to drive 30 min out of my way to find a grocer that stocks these. And they only have 2 flavors.
What's up with that?
Some of that sugar naturally occurs in the milk, so I imagine it can't be easily removed. But Dannon, Yoplait and several other brands have "light" versions with artificial sweeteners.
One cup of plain, nonfat yogurt has 16gm sugar, from the milk since this example has no other ingredients.:
I know this probably isn't what you want to hear, but your best option is to start with plain Greek-style yogurt (store-bought or homemade) and flavor it yourself. That's what I do. Also, the bacteria digest some of the lactose & convert it to lactic acid, so the higher the concentration of active cultures in your yogurt and the longer you let it ferment or "age," the lower the sugar level.
Most of the popular brands with fruit contain added sugar. Plain yogurt often does not. Right now I have Pavel's nonfat Russian yogurt and Straus European style whole milk yogurt. Neither of these have added sugar. Sugars are reported as 15g/c for Pavel's and 7g/c for Straus. This is presumably lactose, which is ok.
If I want fruit in my yogurt, I can add fresh fruit.
I just buy plain unsweetened yogurt and add a dab of jam or honey if I want it sweeter. Otherwise I just add fruit or nuts.
