Suarez was suspended from 'all football-related activity' until October after biting the centre-back in Uruguay's 1-0 win over the Azzurri last month.
"Suarez's bite? I understand it," the former heavyweight champion told social network site Reddit during a Q&A session. "It was a blackout moment which can happen at times.
"It was just one moment in which the competition can make the blood in your veins boil and it overpowers your rationality. Sometimes you become something that you are not."
Earlier today, FIFA rejected appeals from Suarez and the Uruguayan Football Association and upheld the 27-year-old's punishment.
It was the third time that Suarez was sanctioned for such an offence, having also received bans for similar incidents whilst representing Liverpool and Ajax respectively.
