4 food groups to lower inflammation, support your immune system and help you age well | Dr Jeffrey Bland

That’s the idea we explore today with biochemist Dr Jeffrey Bland, widely known as the father of functional medicine. He co-founded the Institute for Functional Medicine and wrote The Disease Delusion, one of my all-time favourite books!

We bring the research back to your kitchen with four food priorities for gut health, immune resilience and healthy ageing: polyphenols, fibre, healthy fats and fermented foods. Plus, why we all need to eat more bitter foods!

In this episode:

• How food can influence gene expression
• The link between immune health, metabolism and ageing
• Polyphenol-rich foods and why variety matters
• Fibre and fermented foods for gut health
• Omega-3s, olive oil and inflammation
• Fish versus fish oil supplements
• Bitter foods and how they may help regulate appetite
