There is a close vote in progress for this question: 
[What kinds of milk are low in carbs?](https://cooking.stackexchange.com/questions/35651/which-milk-is-good-for-a-low-carb-diet)

While obviously, we explicitly have health and nutrition questions as off topic, this one doesn't mention health. It specifically and only asks about a factual statement of composition (carbohydrate content) of certain foods.

While I don't think it is a great question, and one can reasonably guess the OP's intent is to interpret the information through a health or nutrition based lens, the question itself doesn't make any such claims or questions.

Where do we draw the line for questions like this?
