Madonna's Secret for Longevity: Bacteria? Probiotics may help her stay healthy By Evann Gastaldo, Newser Staff Posted May 9, 2012 10:25 AM CDT 25 comments Comments Madonna Launches Her Signature Fragrance 'Truth Or Dare' By Madonna Macy's Herald Square on April 12, 2012 in New York City. (Getty Images) (Newser) – If you’d like nothing more than to remain as perpetually youthful as Madonna but you don’t have $86,000 to spend on your face, good news: There is another way. Madonna fancies fiber-rich foods and probiotics, or "good bacteria," an alternative diet touted with aiding digestion, fending off disease, and generally improving health, Bloomberg explains. Think fermented soy beans, whole grains, and seaweed, while staying away from animal products, processed food, white sugar, and coffee. All this is prepared by Madonna’s personal chef, Mayumi Nishimura, who has of course written a cookbook. Its preface was penned by none other than the Material Girl, who says, "I feel better than I did 20 years ago" after following the diet. Of course, if you can’t afford your own personal chef, you can ingest the many probiotic-rich supplements and products currently being hawked by many companies. "This diet that Madonna is following is very sensible," says one researcher. "The bacteria that live inside you are fulfilling very important functions."
