That is relatively benign compared to what I've seen before. I normally refrain from repeating misinformation, even for debunking it but I will make an exception (or two). I've seen comments ranging from "salt intake doesn't increase blood pressure because you pee what you don't need" to "blood glucose levels aren't good for diagnosing diabetes".
Edit: OK, that's not really a "range". I have no idea why I phrased it like that. Both are very dangerous statements that can be life threatening if the wrong person believes it. I just hope that comment didn't cause any diabetic ketoacidosis cases.
