The Mediterranean diet is the true elixir of eternal youth. Whether we practice sports or not, whether we suffer from any pathology or are healthy, the Mediterranean diet promotes health and rejuvenation. The explanation must be found in the telomeres, DNA segments located at the end of the chromosome whose length and state determine the quantity and quality of life of the individual. Today we know that the consumption of abundant fruits and vegetables within a context of the Mediterranean diet lengthens our telomeres and brings us closer to longevity without disease. With strict scientific rigor, Dr. Lorenzo Pérez Castillo offers readers information on the exceptional scientific moment we are experiencing in the conquest of longevity, rejuvenation and health, and includes exhaustive information on the different foods and their effects, with guidelines and menus to reduce body weight, boost the immune system, stop and even reverse aging and tackle different pathologies from food.
