Jimmy Doherty goes in search of the World’s best diet and discovers Ethiopian superfood and Icelandic rotten fish on his new channel 4 series The World’s Best Diet.

Jimmy says: “We start off with the countries that have pretty poor diets, countries that suffer with obesity and work our way to the best places in the world to eat.

The worst are obviously western cultures like the States and Mexico. For many years the big pariah in our diet is fat but now sugar is the issue.

It is a real eye opener. When you look at the global picture, all our diets are becoming very similar. The more processed the food becomes, the more unhealthy the nation becomes.”
