Vince, who is vegan himself, has repeatedly discussed the importance of moving away from animal products for the good of the planet and human health. He recently slammed animal agriculture in a speech at the Restore Nature Now march in London, saying that farming animals was the “cow in the room” of the climate and nature crises.

At the Labour Party Conference, he said that he would be speaking to the government about introducing “climate and sustainability” into the school curriculum.

Vince also stressed that plant-based meals are better for children than animal-based ones. Vegan diets are known to reduce the risk of a number of chronic diseases, including heart disease, type 2 diabetes, and some cancers. Processed red meat, for example, is linked to increased risk of colon cancer, while dairy may cause breast and prostate cancers. “We shouldn’t be forcing these unhealthy products onto our kids,” Vince said.
