In part two of my conversation with Harvey Fortis – nutritionist, researcher, and performance specialist working with INEOS Cycling – we move from theory into practical action. Harvey and I dig into the specific foods, habits, and daily choices that nourish the microbiome and help it thrive.

We talk about fibre, fermented foods, stress, sleep, pre- and probiotics, the Mediterranean diet, and how simple, consistent choices can transform gut health for athletes and everyday individuals alike.

 

Key Topics

• Why variety in your diet is key to microbial diversity
• Fibre vs fermented foods – understanding their different roles
• How to audit your current diet and identify triggers
• The truth about IBS, intolerances, and exclusion diets
• Prebiotics vs probiotics vs symbiotics – what they actually do
• How stress, sleep, and lifestyle shape gut balance as much as food does
• The Mediterranean diet as a model for long-term gut health

Key Quote ( 01:27:58 )

“Every meal needs to feed you – and your microbes. When you look after your gut, you’re really looking after your whole body.” – Harvey Fortis

Key Message

Gut health isn’t about cutting things out – it’s about adding the right things in. Feed your microbes with colour, fibre, and variety, and you’ll build the foundation for lasting health and performance.
