And it is just as vital an ingredient for Jamie Oliver in building his business, it seems.
The celebrity chef has come out in favour of a vegetarian lifestyle – just ahead of the launch of his vegetarian cookbook.
He has revealed he tries to be vegetarian two or three times a week, and said adopting such a lifestyle would save people “a load of money”.
He described the experience as “an absolute joy” and encouraged others to enjoy “more plant-based delights” because it is “beneficial for the environment and your wallet”.
