Nutritionally speaking potatoes actually contain almost everything required for a human diet.
I've never been that keen, and don't eat them any more, but there's a reason the Irish stopped eating fish and started eating potatoes

Personally my lie carb bread is pretty damn good.
Lots of protein and fibre.
But the real perfect food has to be Tim hortons donuts

Oats, the weird thing about oats is that I like pretty much everything made with them except porridge.
Hell I even put them in sausages as a much better alternative to rusk.
Porridgeis just too slimy for me to eat.
So donuts and spoke and garlic roast chicken.
Mind you someone said apples were healthy ?
Lots of sugar in apples, pretty much all fruit is loaded with carbs/sugar.
And so is milk, almost as much sugar as soda.
Yes lactose is sugar.
Cheese is perfect food
