At 41-years-old, combat sports legend Mark Hunt may have decided to make a serious change to his lifestyle. The 'Super Samoan' posted a disturbing video of animal cruelty on his Facebook feed with the caption, "I'm going vegan, hate this."

The video provides coverage of the inner workings of the fourth largest pig farm in the United States. Pigs and piglets can be seen suffering immensely, as they are left to live out their short lives in a grotesque environment and face violent abuse from the employees.

Vegans, similar to vegetarians, do not eat meat, but also do not consume any animal products what so ever. That means Mark Hunt will no longer be eating any dairy products, eggs or honey. As well as encompassing the diet, veganism also forbids the purchase of animal products such as leather, fur, silk, wool and certain cosmetics and soaps.

One of the most outspoken MMA fighters on veganism is former UFC lightweight contender, Mac Danzig. Danzig switched to a plant-based diet in 2004 and has appeared on the acclaimed "Forks Over Knives" documentary. Boxing legend Mike Tyson also switched to a vegan diet in 2010.
