Uh? Telling the population that they should eat what they want without educating themselves about the consequences makes absolutely no sense at all. There's no need to bother people with every bite they take, but disregarding every food science argument as subjective and irrational is unconvincing in itself.
Now where did I slam "food science"? What I'm against is vegevalengelising (thanks to whoever coined that term in this thread). I don't see an abundance of "food science" arguments in PETA's propaganda, for example.
I have no issues with advising a remote population how to avoid goitre, for example. But that having been said, what passes for "food science" in the modern context also needs to be tempered with some degree of circumspection. For instance, I see lots of nutrition websites, even the ones with mainstream medical backing, extolling the virtues of salad-consumption. Salads are not all-good. Raw veggies have been implicated in serious foodborne outbreaks - for instance, the E. coli O104

4 outbreak that was finally traced to fenugreek sprouts germinated from contaminated fenugreek seeds.
I have a colleague who's recently been studying the bacterial flora of various vegetables. Believe me when I tell you that raw, even thoroughly washed, veggies are *teeming* with bacteria - and it's not just sprouts. Now it probably doesn't matter at all when the eater is a healthy person with an intact immune system. But what if it's someone with cancer, on chemotherapy, who's eating the stuff? If that someone isn't specifically advised against it, I think he might go out and eat salads or drink freshly juiced fruits or veggies, assuming they're "healthy" options. It hasn't yet been clearly established how dangerous this is to an immunocompromised individual, but the risk is plausible.
So I'm actually in agreement with you about people being educated about the *nutritive value* and *safety* of the stuff they eat, but I'm against people being harangued about the *ethics* behind the production of the food they choose to consume. I hope that makes it clearer.
(PS: I'm speaking as a former, "recovering" haranguer/vegevangeliser. I've realized the futility, and to some extent, hypocrisy, of the position I used to hold and preach).
