In a new interview with the Daily Mail on Thursday, the Hollywood star says he's now taking care of his health better than he ever did in the past. During his battle cancer, the celebrity father-of-three embarked on an intensive eight-week course of chemotherapy and radiotherapy, which ultimately changed his outlook on his life.

Douglas said, "I'm great, five years clean and trying [these new diets], something called gluten-free and I must give it high recommendations for you out there."

He added, "I've lost a few pounds from it already, and it supposedly helps your memory and your energy and so I highly recommend it."

Douglas also opened up about his life with his wife, actress Catherine Zeta-Jones and their two children, Dylan and Carys. The couple will be celebrating their 15th wedding anniversary in November of this year. The family splits their time between New York City and Bermuda, where he also spent most of his childhood.

Douglas explained, "We are really, really happy and enjoying our time together and enjoying [time] with the kids, it's a great time. Bermuda is very special. I was raised there with my mother who passed away just recently and I'll be taking her ashes back to Bermuda soon."

He added, "My mother's side of the family, you should know, is Scottish. They were originally, say, privateers and ended up in Bermuda in the 1600s and so my family established itself in Bermuda in the 1600s."
