will only eat purple food. The pop diva is convinced mauve-colored foods like red grapes and plums - known for their anti-ageing benefits - will stop her developing wrinkles. The songstress, who devised the diet with her nutritionist, now munches purple meals three days a week.
A source is quoted in The Sun newspaper as saying: "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'."
"Purple food can prevent breakdown of collagen and slow the wasting of muscles."
It isn't the first time Mariah has tried a bizarre diet. Earlier this year, it was revealed she was living on plain fish and soup in a bid to shed her excess pounds. The curvy star took all calorific treats off the menu until she reached her target weight. She admitted she had been on a "really bleak diet, which is basically just soups and fish prepared really blandly."- Mariah Carey picture gallery
