Taking inspiration from fellow actress Gwyneth Paltrow, Hollywood star Cameron Diaz, who has a body to die for, is writing a nutrition book to inspire others to live a healthy and fit life. While in the weekly lifestyle journal Goop!, Gwyneth provides wellness tips, recipes and fashion advice to the readers, Diaz will write about the importance of nutrition and staying healthy for young girls in her first book. ''Cameron has become very close to Gwyneth and it's been very interesting for her to see what Gwyneth is doing with Goop!, a close source said. ''She's been inspired by Gwyneth and the way she uses her fame to influence and help people. Now Cameron wants to do the same,'' the source said. Since the death of her father Emilio Diaz in 2008, Cameron has become very health conscious and is keen to ensure the book - which will feature advice from celebrity pals Drew Barrymore, Jennifer Lopez and Gwyneth - is not perceived as a diet guide. ''Everything changed for Cameron after her father died. She realised what is important and started to think more and more about her health. This book isn't about her. And it's not a diet of any kind. Of course, it's her own journey that has helped her realise what's important, but she wants the book to appeal to everyone, and not just be about her own food choices,'' the source told E! Online. The source added: ''She wants to use her celebrity to make a difference. She knows she is a role model to girls and she really wants to use that position to do good. Cameron is going to be visiting high schools around the country to talk to teenagers about their food choices and what is important to them, she said.
