Patrick Peterson was diagnosed with diabetes last season and lowering his sugar intake was one of the most significant byproducts.
"Being as lean as I am and being a world-class athlete, you think you can get away with a lot of things," Peterson said. "And at some point in time, your body is definitely the temple and you have to make sure that you have to listen to your body. So, at this point in time, my body was like 'no more sweets,' and [you] have to put it down and slow down a little bit, so that's what it has to be."
Peterson, 24, said he was diagnosed around Week 7 last season, when Arizona played at Oakland on Oct. 19.
Peterson learned diabetes could be life threatening if it's not treated carefully.
"Talking to them definitely got me through it," he said.
Peterson called the period when he didn't know what was affecting him "very tough." It also showed on the field. Peterson allowed four of his eight touchdowns in the first seven weeks, according to Pro Football Focus.
"I'm looking at it ... I'm a world class athlete and I can't figure out what's going on with my body," he said.
More than eight months after his diagnosis, Peterson said "everything's going well right now."
