Actress Cameron Diaz shares health tips in new book

Actress Cameron Diaz has written a new health book to address issues which she says are faced by young women in today's society.

The Hollywood star - who is well known for her own healthy lifestyle offers information and advice on fitness, health and wellbeing in The Body Book.

In an interview with the Mail on Sunday's You magazine, Diaz said she decided to write the book two years ago after realising "nobody else was going to do it".

"I had to find a way to share the knowledge that I have about my body at 41 - and wish I'd had at 21," she said.

The book deals with a number of topics, including healthy eating, female hair removal, and confidence building.

"Food is your friend and you have to embrace your hunger absolutely - because it's not going to go away.

"A few of my girlfriends don't understand this and they say things like, 'What is your secret?' and I say, 'I don't have secrets, this is science'.", she added.

Diaz, appears as the cruel Miss Hannigan in the new remake of musical Annie where she has been giving advice to some of the film's young female extra.

"I try to let them know that being 'pretty' will not sustain them," she said.

"When I talk to them I resist that instinctive urge to say, 'Oh, you are so cute,' and instead ask, 'What grade are you in at school?' or, 'What is your favourite subject?' Because every time we address our daughters or our nieces by saying, 'You look lovely today,' we are reinforcing the idea that the most important thing for a woman is to look good."
