It seemed the only way to answer those questions was to spend a day with Frank Fiore.

So producer Sophie Anton and I took the train to Milton Keynes, taxied along the densely tree-lined roads, and we arrived at the hospital early.

But Frank had beat us to it.

He'd been at work since seven o'clock, as usual, it turned out, an hour before his shift should start.

Frank, this isn't your first NHS job.

I mean, you have a gigantic task.

You know, we have created in Britain a junk food culture.

We eat more junk food than anyone else in the Western world apart from Americans.

And, you know, at the minute you have, I'm facing, you have your back too.

Big refrigerated holders of every soft drink, ultra-processed food in the world.

You know, you don't get daunted at what you're faced with.

In fact, there's a screen behind the healthier eating option Spanish omelette with a mixed side salad.

£2 for staff, so you get a good pick up with that.

It's 10.30 where we're off to now.

I wish radio did smells, because it smells so good.

Lucky people here today to have Keralan food.

Thank you.

There's a lot of raw food here, right?

Ten years ago, would you have been getting in purple sprouting broccoli?

Tell us what you've got.
