The dangerous part is "that it's a novel food that was never eaten by humans". All cultures that eat bad food have died, so there is a survivorship bias because we now think "just eat this food": but only cultures who came up with a healthy diet have survived throughout history. Nothing guarantees you that this food is "healthy" since we cannot analize the long term of effects of these foods with any modern technology.
