She has now reintroduced animal protein back into her diet

Miley Cyrus says she turned her back on the vegan diet because it negatively impacted her brain function. Speaking as a guest on the Joe Rogan Experience, Cyrus said she has now had to reintroduce animal protein back into her diet. The 27-year-old actress and singer said: "I was vegan for a very long time and I've had to introduce fish and omegas into my life because my brain wasn't functioning properly." Rogan interjected, telling Cyrus "not to tell that to the vegans". "That's ok, they're gonna come for me," she responded.

"I've got 22 animals on my farm in Nashville, I've got 22 in my house in Calabasas - I'm doing what I need to do for the animals." Cyrus said giving up on veganism has boosted her cognitive function, and given her a renewed sense of mental clarity. "When it comes to my brain, now I'm so much sharper than I was. I think at one point, I was pretty malnutritioned (sic). "I remember going to Glastonbury and I was running on empty." Cyrus said she was on the strictest possible vegan diet, including additional supplements and protein shakes. Vegans routinely take supplements such as Vitamin B12, as that nutrient is commonly lacking in a plant-based diet. "Some people can, I could not." Miley Cyrus was appearing as a guest on The Joe Rogan Experience (JRE). One of the world's most popular podcast shows, JRE recently moved exclusively to Spotify in a deal rumoured to be worth over $100m. JRE receives 190 million monthly downloads, and is also one of the biggest shows on YouTube. However, by the end of the year, Rogan's full-length shows will only air on Spotify's new 'vodcast' section.
