The science behind food that isn’t food, why you love it and why you should not fear it all | Prof Tim Spector & Prof Sarah Berry

Ultra-processed foods (UPF) represent a fundamental shift in nutrition science, moving beyond simple macronutrient labels to consider how processing methods, additives, and food structure impact metabolic health. Research indicates that UPFs override natural satiety signals, with studies showing that individuals on UPF...

Most replayed moment: The hormone that controls your weight | Dr Andrew Jenkinson

Leptin functions as the primary hormonal regulator of human weight, signaling the hypothalamus to adjust appetite and metabolism based on energy storage levels. When insulin levels remain chronically elevated due to diets high in sugar, refined carbohydrates, and frequent snacking, the leptin signal becomes blocked. Th...

The secret to coping with stress - how to protect your brain and body, and feel calmer now | Prof Carmine Pariante

Stress functions as a biological mismatch between perceived environmental challenges and an individual’s capacity to cope. While acute stress once served as a vital survival mechanism, modern chronic stress keeps the sympathetic nervous system and cortisol levels perpetually elevated, triggering systemic inflammation t...

Most replayed moment: The hidden battle inside your gut | Tim Spector & Nicola Segata
