I said evidence. Which is not opinion. Solid evidence is often found through a non-bias peer-reviewed scientific study. And finding these studies to support your health advice is worth the time. And there are plenty of them already written and well reviewed don't worry. Health is pretty important and care needs to be taken in giving diet-related recommendations especially I think.
Yeah you are right, of course you don't have to label it as opinion. I know I would so I wouldn't be misinforming somebody and to help them think twice about anything I was saying.
I said you could at least do that, if you wanted of course. Not "do what I say".
Obviously, you can post whatever you'd like
