London: Diva Mariah Carey is fighting her battle against ageing by using a monochrome diet as a weapon.
The pop queen is reportedly eating only purple foods, with ingredients such as red grapes and beetroot, thrice a week because of their anti-ageing benefits.
"It sounds off-the-wall but it's a huge injection of healthy food in one go. Purple products are nature's best weapons in the battle against ageing. There's a saying that 'a plum a day keeps a facelift away'," the 'Sun' quoted a source close to the star.
She devised the diet with her nutritionist to use skin-boosting foods high in anti-oxidants and vitamins.
"Purple food can prevent breakdown of collagen and slow the wasting of muscles. So Mariah is bulk-eating them," said the source.
