From gut health to brain health, inflammation to hormonal shifts, Immune to Age is the ultimate preventative care framework that equips readers with the knowledge and tools to reclaim control over their health and ensure every year is a good one. In an era of unprecedented longevity and personalised health information, we have more tools than ever to extend our lives. Yet, despite these advancements, few of us understand the hidden processes that shape our health, leaving many of us struggling to unlock the secrets of staying well and thriving at every life stage. Long misunderstood as merely the body's first line of defence against disease, we are only now beginning to understand the crucial role that the immune system plays in how we age. This mind-bogglingly complex network - intricately woven throughout our entire being, from brain to big toe - drives everything from metabolic function to brain health, and it is the single greatest arbiter of our lifespan and, more importantly, our healthspan. In Immune to Age, immunologist Dr Jenna Macciochi blends cutting-edge scientific expertise with beautiful storytelling and actionable advice to explore the importance of good immune health at every stage of life, from conception right through to our wintering years. This is a paradigm shift in the way we think about time, ageing, and being truly well.
