Miranda Kerr counts spinach as the key to her stunning figure.

The Australian model - who is dating 'Pirates Of The Caribbean' actor Orlando Bloom - eats as much organic food as possible and works hard in order to maintain her health.

She said: "The first step is eating healthy. I predominantly eat organic when I can. I eat extremely healthy because when I do, I have more energy. I love spinach, avocado, lots of greens and broccoli.

"I'm pretty much 80 per cent healthy, 20 per cent indulgent, because I don't believe in depriving yourself.'

She also said she feels a responsibility as a model to promote healthy eating, particularly to the younger and more impressionable members of society.

She added to E! Online: "As soon as you step into the public eye you need to take responsibility for the people you are influencing.

"Body image is something that the majority of young women struggle with and I do think it is important that models are seen to be healthy and at a weight that works for their body type."

Miranda - who models for lingerie firm Victoria's Secret - also gave her tips for picking the perfect bikini.

She said: "Everyone has different body shapes so it's best to find a swimsuit that flatters your individual shape. But most importantly, with the right attitude and confidence any swimsuit will look good!"
