The Fibre Factor

We’re in a fibre famine.

Modern food systems have stripped fibre from our plates, leaving us with ultra-processed foods that are fibre-poor and nutritionally hollow. Even when fibre is added back in, it’s often just one extracted form, missing the diversity our bodies crave. What is more, fibre is so much more than a remedy for constipation or something your grandma worries about: fibre is the nutrient that could transform your health.

In The Fibre Factor, Dr McMillan reveals how embracing the diversity of fibres can revolutionise your health and well-being. Drawing on cutting-edge research, she explains why fibre is the ultimate multitasker, fueling your gut microbiome, which in turn impacts everything from digestion to mental health, brain function and immunity. It also supports your heart by regulating cholesterol and blood pressure, and helps stabilise blood sugar, manage weight and reduce inflammation. In addition, it plays a role in detoxification by binding and eliminating toxins from the body, and is even linked to living longer and ageing better.

Powered by science, this book brings fibre back in a fresh, modern and downright irresistible way. With practical tips, actionable advice and recipes, this book equips you to rethink your plate and embrace the nutrient your body has been missing.

Fibre is no longer just for gut health — it’s the missing link to unlocking better physical, mental and emotional well-being.
