> It is also unethical to propose a radical change to society with only very tenuous basis in reality: people should be able to demonstrate knowledge (and not just knowledge about what beliefs will prove popular or fashionable) before they engage in public policy discussions. If the person I'm discussing with hasn't tried eating insects at least once (preferably a lot more often) he is doing us all a disservice in even engaging in a public discussion of the topic unless perhaps he has deep professional-level knowledge of the nutritional value of insects and the effect of nutrients and anti-nutrients on human health (and "insects are high in protein" alone doesn't begin to be enough knowledge).

That is a strange position. The most that I could contribute is anecdotal evidence anyway. The nutrient composition and the safety of insect-derived food has been rigorously studied, for example in: https://doi.org/10.2903/j.efsa.2023.8009

I linked the EU FAQ on insects in my other reply.
