In an exclusive interview conducted by Adrián Cordellat for La Vanguardia, María Mittelbrunn emphasizes that our true age isn’t measured by the number on our ID, but by the state of our immune system. She explains that maintaining a youthful immune system can delay age-related diseases by reducing chronic inflammation. Mittelbrunn also highlights that lifestyle factors—such as a balanced diet, regular exercise, and controlled caloric restriction—may help rejuvenate our immune response, ultimately extending our healthspan. This insightful discussion challenges conventional views on aging, suggesting that a robust immune system is key to a longer, healthier life.
