Mariah Carey is sticking to a regime of eating only purple food – because she reckons it will help get rid of her wrinkles. The singer has been eating foods such as red grapes and beetroot because of their anti-aging benefits. A source reports, “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 face-lift away’. Purple food can prevent breakdown of collagen and slow the wasting of muscles. So Mariah is bulk-eating them.” [3 July 2006]
