Bear Grylls has said he is “embarrassed” by his past support of veganism, and regrets writing a green cookbook in which he criticised meat eaters. The adventurer, whose diet is now mostly composed of red meat and organs, has claimed he was wrong to think that eating a plant-based diet was good for the environment and his health. “I was vegan quite a few years ago – in fact, I wrote a vegan cookbook – and I feel a bit embarrassed because I really promoted that,” the 48-year-old said in an interview with PA. “I thought that was good for the environment and I thought it was good for my health. And through time and experience and knowledge and study, I realised I was wrong on both counts.” The television star published a cookbook in 2015 called Fuel for Life, which promoted achieving “maximum health with amazing dairy, wheat and sugar-free recipes”.
