Miranda Kerr on her clean and healthy lifestyle

Miranda Kerr, who is expecting her first child with husband Orlando Bloom, has attributed her wholesome country-girl-next-door charm to clean and healthy living.

The Australian model also credited the secret of her glowing skin to an organic plant-based diet and Tahitian noni juice, reports The Daily Telegraph.

Besides advocating regular body brushing, Kerr has developed an organic skincare range, Kora Organics, which she says “is a reflection of my passion for living a healthy, organic lifestyle”.

After a stressful day, Kerr always prefers to wind down with meditation and some power yoga with her husband.

With an aim to share her spiritual secrets with her fans, the New York-based cover girl will launch her debut self-help book, Treasure Yourself, in Australia this month.

“I felt as though it was important for my readers to realise I was not always the person they see on a runway or on the cover of a magazine. I wanted them to know that just like them, at times I struggled with insecurity, bullying, rejection and low self-esteem.” she said.

Treasure Yourself chronicles how she got there, from her days spent playing at her grandparents’ Queensland farm as a child to her current jet-setting life as a catwalk star.

“To me, Treasure Yourself was almost like writing a diary. The book is a very personal account of the life lessons and experiences I have had growing up as a child, right up until the woman I am today," she says.

Kerr said she also takes a ‘vision book’ during her travels, to keep herself focused on her dreams and ambitions.
