Eilish grew up vegetarian and officially switched to a vegan lifestyle in 2014. Regarding her choice, she went to Tumblr to explain why she decided to go free of animal products in her diet. In 2018, she wrote on her blog, "i went vegan like four years ago. there were a lot of reasons. i love animals and i just think there's no point in creating something out of an animal when the animal is already there. leave animals alone. damn. also im lactose intolerant and dairy is horrible for your skin and my skin is VERY aware of that."
