LONDON – Gwyneth Paltrow (search) says she partly blames herself for her father's untimely cancer death three years ago — agonizing that she should have done more to keep him healthy.
"I wasn't adamant enough in cleaning up his diet and getting rid of the cancer," the Oscar-winning actress told London's Evening Standard.
"Now I really feel I could have extended his quality of life. But I wasn't as strong as I should have been."
In October 2002, Gwyneth was devastated when her director dad, Bruce Paltrow (search), a longtime smoker, died of a heart attack brought on by complications from throat cancer and pneumonia.
"I was in denial for so much of his illness. The thought of life without my father was totally unfathomable to me," the 32-year-old star said.
"He went for four years when he thought he was cancer-free, or so we thought. We felt 'he's going to be fine now, let's move on.' "
She said a nutritionist had urged her father to adopt healthier eating habits, forgoing everything from coffee to dairy products, "but he didn't want to stand out.
"I really believe that what you eat has a huge effect on your health. My father smoked for a long time. He had a big vodka every day when he got home from work."
Her dad's passing has helped Gwyneth appreciate life.
"My father's death changed my outlook on my life a lot," she said.
"You must find pleasure and beauty in the most simple things in life and in living for the moment."
Paltrow recently sold her $7.5 million Greenwich Village townhouse, and lives in London with her rock-star husband Chris Martin of Coldplay and their daughter, Apple.
