"Sometimes I drink, sometimes I don't drink, but for this fight I stopped a little bit," Machida said of his urine therapy. "It's not a problem for me."
In past interviews, Machida admitted that he drank his own urine to replenish lost minerals in the body by recycling his own fluid.
Machida, who will be making his UFC middleweight debut at UFC Fight Night 30, hasn't been utilizing that type of therapy in preparation for his fight against Munoz.
"I don't know about the future," Machida said. "That's why I say to everybody, I'm just arriving. It's hard to say about a title shot. Everybody is asking about it, but I prefer not to talk about it."
Machida previously competed in the UFC's light heavyweight division, but he doesn't foresee any problem competing at a high level at 185 pounds.
"I just dropped down because I was going to fight against (Jon) Jones, and that couldn't happen," Machida told MMAjunkie.com. "The UFC gave me an opportunity to fight at 185. I want to stay active."
Machida plans to put on a show at UFC Fight Night 30. He has nothing but respect for Munoz, but he says he'll be able to put emotions aside to punch a friend in the face.
"I have no problem with me and him," Machida said. "Mark Munoz is a great guy. We are friends, but we are professionals, too. I think this fight can show the world that friends can fight each other, but with a lot of respect, and (they) will put a great performance on. It's not a problem."
