“Doctor Who” has progressed a lot over the years, adding LGBT friendly characters; having the Doctor get married and have children; and now the Doctor is a woman. The time-traveling Doctor has always been an instrument of change for the series, and PETA UK is hoping to add one more detail to the Doctor’s ever-shifting personality, making her a vegan this time around.

After it was announced by BBC America that Jodie Whittaker will be taking on the role of Doctor Who in the next season of the series, PETA U.K. has written an open-letter to showrunner Chris Chibnall asking that he make the character vegan.

“Eating dead animals simply doesn’t fit with the Doctor’s moral compass since … the show has ‘the central message of love for life in all its forms,'” writes PETA U.K. Director Elisa Allen.

In a statement released to the press, PETA U.K. pointed out that vegan eating “has been shown to help reduce the risk of suffering from cancer, obesity, diabetes, and heart disease,” which does sound right-up the Doctor’s alley.

Chibnall, PETA Director Elisa Allen said in her statement:

“Animals, like humans, are smart and sensitive and feel pain. But in the meat, egg, and dairy industries, they’re crammed into windowless sheds, torn away from their mothers, forcibly impregnated, mutilated, and sent to an early death – and many are slaughtered while they’re still conscious. Not only is switching to a vegan diet infinitely kinder to animals, it’s also one of the best ways to protect planet Earth, as animal agriculture is a major producer of the greenhouse-gas emissions that contribute to climate change. Plant-based foods are naturally cholesterol-free as well as rich in vitamins and minerals, and a vegan diet can reduce our risk of suffering from cancer, obesity, and diabetes. Considering all the benefits that eating vegan has for a person’s heart, it’d be doubly beneficial for the Doctor!”

The next episode of “Doctor Who” will be the Christmas episode (shown above), which will feature the final performace of Peter Capaldi as the Doctor.
