I devised a methodology that would ensure the widest possible scientific basis for my recommendations. I call this method the Five Pillars of Longevity. These pillars do not refer to specific interventions such as diet and exercise, but to five disciplines that provide the foundation for my nutrition program: 1) basic/juventology research (juventology, as I will explain, is the science of staying young); 2) epidemiology; 3) clinical studies; 4) studies of centenarians; and 5) the understanding of complex systems (like cars, for example).
