It's not reckless to recommend someone try a food and see if it helps them feel better. Trying diverse foods is nice (as in, good for the variation in life) and in this case it may transcend the immediate niceness into a generalised well-being. Nobody here is recommending natto instead of whatever your doctor prescribes (which I guess you are implying) and you'd have to be severely mentally handicapped to assume this is what was written. In such a scenario you should not touch the internet unsupervised anyway, because all sorts of normal statements become potentially dangerous.

In short: Real life shouldn't have to be a ball-pit surrounded by rubber tiles. We're all adults here.
