From The New York Times:
One morning in early January, David Murdock awoke to an unsettling sensation. At first he didn’t recognize it and then he couldn’t believe it, because for years — decades, really — he maintained what was, in his immodest estimation, perfect health. But now there was this undeniable imperfection, a scratchiness and swollenness familiar only from the distant past. Incredibly, infuriatingly, he had a sore throat. “I never have anything go wrong,” he said later. “Never have a backache. Never have a headache. Never have anything else.” This would make him a lucky man no matter his age. Because he is 87, it makes him an unusually robust specimen, which is what he must be if he is to defy the odds (and maybe even the gods) and live as long as he intends to. He wants to reach 125, and sees no reason he can’t, provided that he continues eating the way he has for the last quarter century: with a methodical, messianic correctness that he believes can, and will, ward off major disease and minor ailment alike.
So that sore throat wasn’t just an irritant. It was a challenge to the whole gut-centered worldview on which his bid for extreme longevity rests. “I went back in my mind: what am I not eating enough of?” he told me. Definitely not fruits and vegetables: he crams as many as 20 of them, including pulverized banana peels and the ground-up rinds of oranges, into the smoothies he drinks two to three times a day, to keep his body brimming with fiber and vitamins. Probably not protein: he eats plenty of seafood, egg whites, beans and nuts to compensate for his avoidance of dairy, red meat and poultry, which are consigned to a list of forbidden foods that also includes alcohol, sugar and salt.
