Paltrow, Hanks write for healthy home book

Gwyneth Paltrow and Tom Hanks are among a host of celebrity parents who have written for a book about healthy living for children.

Healthy Child Healthy World by Christopher Gavigan also contains essays from Tobey Maguire, Kate Hudson, Brooke Shields and Keri Russell. Two-time Oscar winner Meryl Streep wrote the book's foreword.

In the book, Paltrow states: "From the beginning, my kids have eaten organic. I make a lot of their foods myself. Some people say it sounds difficult - but I don't find it so...

"The more I learn about food, the more amazed I am at how their properties can basically fix anything."

She has two children, three-year-old Apple and two-year-old Moses, with her husband, Coldplay singer Chris Martin.
