Professor Tim Spector: How nutrition influences mood, energy and long-term brain health

Professor Tim Spector discusses the significant impact of gut health on mood, energy, and brain function in his new book, 'Good Mood Food.' He explains how diet influences the gut microbiome and warns that ultra-processed foods can trigger inflammation.
Why it matters
Understanding the gut-brain axis is increasingly important for public health, as it offers actionable dietary strategies to improve mental and physical well-being.
What we eat doesn’t just affect our physical health, it can also play an important role in how we feel, think and behave.
According to Tim Spector , a medical doctor, gut health expert, scientific co-founder of health science company ZOE and professor of epidemiology at King’s College London, the connection between our gut and brain is much more powerful than many people realise.
In his new cookbook, Good Mood Food, written with Dr Federica Amati and featuring recipes by Kathryn Bruton, Spector explores how the food we eat can influence our mood, energy levels and long-term brain health.
The book aims to make improving gut health accessible, affordable and enjoyable, with everything from comforting family favourites to quick and easy snacks.
“There’s a lot of recent science particularly linking the gut and the brain that most people don’t know about,” Spector says.
