Summary
What if ageing well had less to do with your genes, your skincare routine or the supplements you take ... and more to do with your immune system?
Most of us think about immunity as something that only matters when we’re fighting off a cold or flu. But actually, it’s quietly working behind the scenes every single day shaping how we feel, how we recover and how long we stay well.
Our immune health is also constantly evolving and changing over our lifecycle. From birth to our 20s, midlife and beyond our immune system plays a critical role in how we feel, our risk of disease and how well we age.
Dr Jenna Macciochi is an immunologist specialising in the intersection of nutrition, movement, mind-body practices and lifestyle with the immune system in health and disease.
She’s also a brilliant science communicator who has a beautiful way of weaving science with story. In her new book, Immune to Age, Dr Jenna reframes immunity not as a fortress that springs into action, but as a lifelong partner guiding us through the seasons of our lives from the day we’re born to the way we age.
We dive into:
- Why inflammation is not just good or bad
- How your immune system changes with age
- What to focus on in your 20s, 40s and beyond
- The role of inflammation, infection and stress in ageing
- Supplements like creatine, collagen, taurine, peptides and nootropic mushrooms
