Yes they are.

They wouldn't sell nearly as much yogurt if it was not sugared-up.

And now the vast majority of them are not only sweetened within an inch of their lives, they're also fat-free.

I'm trying to comprehend how there was no difference in diabetes prevention between the ones who ate unsweetened yogurts and the one who hate sugary yogurts. The only thing I can imagine is that yogurt in general is considered to be a relatively healthy food - sugar or no sugar, fat or no fat.

People who care about their health are eating yogurt, where as people who don't care about their health will very likely simply eat candy or ice cream.

If they're eating yogurt for perceived health benefits, even if they're choosing the sugary ones, it's possible that they're making somewhat better food choices in general, even if they're not ideal food choices:

Someone who doesn't care one bit about healthy eating might choose a Big Mac, large fries, and full-sugar large drink, with an apple pie for dessert.


The more health conscious individual might have a salad, a deli chicken sandwich on whole grain, diet soda or water, and a yogurt for dessert.

Yeah, we can argue that the sandwich is providing a lot of carbs, but it's still only about 30 g carbs compared to the 46 carbs of a Big Mac, a salad will have very few carbs compared to the large fries (65g carbs). And of course we can talk about how the diet soda is bad for you because of the artificial sweeteners - but that diet soda won't have any carbs at all, compared to the 77 g of sugar in the large drink.

Even far less than ideal food and drink choices can make a huge difference in how much glucose floods the system after a meal, which could very well be why even those who eat full sugar yogurts are still managing to avoid diabetes.
