If we feel run down and we want to support our immune system, most of us tend to pop some vitamins. But an incredible 70% of our immune system is in the gut, so gut health is crucial in our defence against illness.

Is it possible to improve our gut health with simple changes to our lifestyle? Yes – with this essential recipe book from nutritionist and immunity expert, Kate Llewellyn-Waters.

Kate explains in simple terms how our immune system and gut work, how we can help improve our immunity every day, what autoimmune conditions and allergies are, and which are the key non-food contributors to gut health and immunity, such as sunlight, sleep, mental health and exercise.

The main part of the book offers 100 everyday recipes, all using accessible, supermarket ingredients and offering helpful switches or additions to suit you and your family's needs, as well as practical meal plans to make life even easier.
