The Ultimate Diet

Let me get this straight.

We can't eat beef because of mad cow disease.
We can't eat chicken (or birds) because of the avian flu.
We can't have fish: potentially toxic mercury levels.
We can't have eggs: salmonella.
Fat has long been seen as the enemy for obesity.
And now, carbs are under attack by Atkins.

So ... what's left to eat besides salads and legumes?
