An opinion piece published by online giant Metro UK suggests that veganism is no longer a minority interest.
Journalist Miranda Larbi writes: "This, surely, is proof that veganism has gone from being the fringe interest of hippies, to being a mainstream concern.
"Once we get sportspeople – multimillionaires who spend half their time being papped at glamorous parties and beach clubs – talking about the environmental and health impact of a completely plant-based lifestyle, that’s when we know we’re making tracks.
"Lewis Hamilton has a huge influence on his fans. He’s probably the only Formula 1 driver many people can name in this country. He’s dated a Pussycat Doll.
"You can’t get much more mainstream than Lewis everyone’s-favourite-guy-from-Stevenage Hamilton."
Hamilton made the switch after watching documentary What the Health. On Snapchat, he claimed he was making the transition for environmental and health reasons - as well as for the animals.
In the days since transitioning he has said: "So far I don’t feel as if I have been missing out.
"But I don’t know how easy it is going to be when I get home. That is going to be a real test.
"Every person I have met who has gone vegan says it is the best decision they have ever made.
"When you watch this documentary and you see meat clogging up your arteries, you see all the stuff they put in the meat, stuff we are all eating, there is no way I am going to disregard that.
"I don’t want in 10 or 20 years to have diabetes or catch any of that stuff."
