As far as I'm concerned the limits on individual choice should be where it stops being something that is their choice and it removes choice from others. If someone chooses not to eat certain types of food it seems to me that is up to them provided they don't try to impose their choices on others.

And now back to the music, this seemed apt:

THE POTATO SONG   by Brian Bedford
How could you do it , it's heartless it's cruel,
It's murder, coldblooded ,it's gross.
To slay a poor vegetable just for your stew,
Or to serve with some cheese sauce on toast.
Have you no decency. Have you no shame.
Have you no conscience you cad.
To rip that poor vegetable out of the earth,
Away from it's poor mum and dad.

Chorus
Oh no don't slay that potato, let us be merciful please.
Don't boil it or fry it, or even freeze dry it,
Don't dice it or flake it, for gods sake don't bake it,
Don't shed the poor blood of that poor helpless spud,
It's the worst kind of thing you can do.
Oh no don't slay that potato , what never done nothing to you.

Why not try picking on something your size,
Instead of some carrot or bean,
The peas are all trembling there in their pods,
Just because you're so vicious and mean,
How would you like to be grabbed by your hair,
and be ruthlessly yanked from your bed,
and have done to you god knows what horrible things,
to be eaten with full fibre bread.
Chorus

It's no bed of roses this vegetable life,
you're basically stuck in the mud.
You don't get around much, you don't see the sights,
If you're carrot or celery or spud.
You're helpless when somebody's flea bitten dog,
Takes a notion to stop for relief.
Then somebody picks you, and cleans you, and eats you,
And causes you nothing but grief
Chorus

There ought to be some way of saving our skins.
They ought to be passing the law,
Just show any body a cute little lamb,
and they all stand around and go ... Awww
Well potatoes are ugly, potatoes are plain,
We're wrinkly and bumpy to boot.
But give me a break, you mean to say,
You eat us because we're not cute.
Chorus
