It's become part of the national conscience to eat 'five-a-day' but recent research is now suggesting that a different approach is better — to eat 30 different plants a week.

"Five-a-day hasn't transformed the health of the nation," says TV chef Hugh Fearnley-Whittingstall. Even people who do eat five fruits and vegetables a day are "often eating the same ones over and over again". But it's become clear how important diversity of plants is in our diets.
