Leading up to New Orleans Saints training camp this year, running back Adrian Peterson changed his diet.
One of the best running backs in NFL history is exploring veganism.
Peterson knows his specific eating habits might be upsetting to real vegans because he's still eating chicken or fish occasionally -- he likes the taste. But, as he approaches his 11th NFL season, Peterson estimates his diet is about 85 percent vegan.
The 32-year-old said he's thought about switching to a vegan lifestyle for a while, but finally made the switch last month after Washington left tackle Trent Williams suggested he watch a documentary called "What the Health" on Netflix, which examines the relationship between diet and chronic disease.
