Is it true that orange juice can help ward off colds? How does age effect our immune system? Is mental health really connected to inflammation?

We are surrounded by bold claims and quick fixes for ‘boosting’ our immune health.

In this expert guide, world-leading immunologist Daniel M. Davis examines the effects of stress, diet, age, exercise, the microbiome and more on the immune system, punctures the key myths, sorts the fact from the fiction and equips us to make informed choices for ourselves.
