ELI5: Why is yogurt usually considered good for you, while ice cream is almost considered bad for you? What makes them so different?

They're both dairy products which are usually loaded with sugar. what makes one good for you while the other is relegated to dessert only status?

Yogurt has bacteria that is purportedly good for you, combined with the fact that it generally has less sugar and fat, makes it a healthier option. The probiotic part is debatable, because studies seem to indicate your gut microbiome returns to its original state after a relatively short time.

In some ways, unless you go for low sugar and fat yogurt, it's like comparing a cheeseburger with a double cheeseburger. The lesser of two evils.
