World Vegetarian Day is observed annually on 1 October by many nations across the globe (though particularly in Europe), and it invites the population to go veggie for the day.
It was first introduced in 1977 by the North American Vegetarian Society, which wanted to educate people about the many positives of a vegetarian lifestyle such as health benefits, saving animals' lives, and preserving the Earth.
To mark the occasion, we’re taking a look at ten of the most veggie Guinness World Records titles ever achieved.
