I have a new favourite wellness guru. And it’s not who you might think | Jay Rayner

Eat food that is mostly healthy, but also eat delicious food that isn't healthy: these are the eminently sensible words of ... Arnold Schwarzenegger

In this, the most glowering month of the year, we all need a guru, and I have found mine. He is a one-time bodybuilder, turned action movie hero, turned (soft) Republican politician and his name is Arnold Schwarzenegger.

At the very end of last year Arnie took to a site which, because I'm an old nostalgic who thinks names should have more than one letter, I like to call Twitter. He said he had been told that lists go viral, so he had written one. The first piece of advice was: You should mostly eat food you know is healthy. There is no magic food."
