He also explained how his restaurants have become targets for vegan activists with '20 scruffy, weird-looking fellas putting iPads of slaughtered animals in front of kids having spaghetti bolognese on a Saturday lunch'.
In March, vegan activists armed with a megaphone and a cow costume campaigned outside a packed Jamie Oliver restaurant in Bristol after the chef promoted 'happy milk' on television.
The protesters from Bristol Animal Save protested outside Jamie's Italian to criticise the chef over comments made in an episode of Jamie & Jimmy's Friday Night Feast.
Meanwhile, the TV star and restaurateur has been highly critical of the Prime Minister's approach to tackling childhood obesity and the now-shelved plan to scrap free school meals for infants.
Oliver said Mrs May's administration was "completely locked down" with her team of close advisers keeping information away from ministers.
Oliver blamed Mrs May's team for watering down the childhood obesity strategy that David Cameron's government had been working on.
Oliver told the Sunday Times magazine: "Look, I have met four prime ministers. They are all very different, but... May's government was completely locked down."
In 2015, Oliver encouraged people to ditch meat for a vegetarian or vegan lifestyle several days a week.
The celebrity chef said the diet would save people "a load of money" and revealed he personally tries to be vegetarian two or three times a week.
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".'
