The Pirates of the Caribbean star admits she is "obsessed" with maintaining a healthy lifestyle but pushed her body to the limit with a super-strict eating regime.

But after suffering a health scare as result of the diet, Harris vowed to eat sensibly and munch vitamin pills to boost her immune system.

She tells Britain's Live magazine, "I'm obsessed with health, which has been an interesting journey for me. I went down the raw-food-diet route, became a raw foodist and got really ill. It was really hard, especially in England in winter, trying to survive on raw carrots.

"I became so ill I was anaemic, so I just stopped that and became a total vitamin junkie. Just eat lots of vegetables, exercise and breathe."
