Jonsson was diagnosed as a teenager as having food allergies to shellfish and raw meat.

Whilst working as a solicitor started writing a food blog at gastroville.com which documented his reviews of restaurants he visited as he travelled.

[2] At the age of 44, he changed his diet and found it gave him a new-found control over his allergies.

He chose to pursue his dream of becoming a chef and opened the restaurant Hedone in Chiswick, West London in 2011.

About ten minutes later a group of people entered the restaurant and attacked Jonsson, who was stabbed in the arm and had to have broken glass removed from his forehead.
