People that consume animal flesh don't always realise where their meat is coming from. I've heard too many people saying they don't want to see videos or images from slaughterhouses or even undercover videos exposing the cruelty to "food animals" just so they can keep eating without a second thought what their parents raised them believing is good and necessary in order to get all the nutrients their body needs. The animals don't need to suffer their whole life and be killed for your belly and body to be satisfied and stay healthy.
The reality is you can find all the nutrients your body needs on a whole-food plant based diet. It doesn't need to be fad or boring. Google is your best friend for recipe ideas. Simply search "vegan recipes" and you'll be amazed with all the options that comes up!
