Actor Ashton Kutcher, who plays Steve Jobs in the biopic "Jobs," was hospitalized after going on the all-fruit diet the Apple founder followed while fighting pancreatic cancer.
"The fruitarian diet can lead to severe issues," Kutcher told USA Today. "I went to the hospital like two days before we started shooting the movie.
"I was doubled over in pain. My pancreas levels were completely out of whack. It was really terrifying."
A fruitarian diet is an extreme version of the vegan diet that only allows fruits, nuts, seeds, vegetables and grains. Ashton, 34, went on the extreme diet as he was preparing to play Jobs, who died of pancreatic cancer in October 2011 at age 56.
Jobs underwent both traditional medical and holistic treatments to fight his cancer. In his later years, the Apple CEO was a strict vegan who followed the fruitarian diet and was also a fan of fasting.
Kutcher, who recently debuted "Jobs" at the 2013 Sundance Film Festival, says he spent hundreds of hours viewing tapes of Steve Jobs in order to get his mannerisms, walk and demeanor down.
"He's a guy that failed and got back on the horse," says Ashton, who's divorcing Demi Moore. "I think we can all sort of relate to that in some place in our life where we are moving forward with something and we fall down. You have to have the guts to get back up and go again. I think I share that as well."
