> The knowledge on the adverse effects on human health due to the consumption of marine organisms containing microplastics is very limited, difficult to assess and still controversial.
I'm not sure that really answers the question you responded to.
It doesn’t mean there isn’t any reason to look at the potential risks; on the contrary, the sooner we acknowledge the risks and take steps to mitigate them, the sooner we have pre-empted any possible health outcomes, independent of what exactly the cause and effect turns out to be.
That is, unless you really, really believe microplastics are somehow good for you.

Yes, that is what the careful wording actually implies. If you'd been more careful with your reading then you could've saved writing the first 2 paragraphs.

You provided some evidence (that is a generous description) wrapped in some snark that didn't back up your claims. What I believe has nothing to do with that, and to intimate that my assessment is based on belief is absurd, I read the results you "provided" - believers don't tend to bother with facts that might contradict them.
Be more careful with your words in future, that'd be my advice.
This is excluding the middle.
Scientists aren't careful because that's some natural state of scientists that has no meaning in the real world. They're careful because drawing noncareful conclusions (or fallacious ones such as excluded middle) is just making stuff up.

”In all biological systems, microplastic exposure may cause particle toxicity, with oxidative stress, inflammatory lesions and increased uptake or translocation. The inability of the immune system to remove synthetic particles may lead to chronic inflammation and increase risk of neoplasia. Furthermore, microplastics may release their constituents, adsorbed contaminants and pathogenic organisms.”
