  • Food additives exposed: The artificial dyes and chemicals to avoid | Marion Nestle

    Food additives exposed: The artificial dyes and chemicals to avoid | Marion Nestle
    Aug 21 2025
    Those long, unpronounceable ingredients at the bottom of food labels—what are they really doing to your health? In this episode, we’re joined by Professor Marion Nestle, a world-leading nutrition expert and author of the groundbreaking book ‘Food Politics’. Marion has spent decades exposing how powerful food companies influence what ends up on our plates — and how little regulation may stand in their way. We dive into the hidden world of food additives and the regulatory systems meant to protect us. While the U.S. allows companies to self-certify ingredients as “safe” without independent FDA approval, Europe and the UK take a stricter approach. But does stricter always mean safer? Marion unpacks how these systems differ, which substances might be harming our health, and what consumers can do to reduce their risk. We explore what the science says about additives, inflammation, gut health, and more.

    Forget crash diets: How to maintain a healthy weight | Alan Aragon & Prof. Sarah Berry
    Aug 14 2025
    Most people who try to lose weight and keep it off end up failing. But what if the problem isn’t you - it’s the diet? In this episode, we cut through the noise of weight loss fads to explore a science-backed method that’s helped countless people make real, sustainable changes. It’s called flexible dieting, and it’s built around the idea that personalised macronutrient targets, food quality, and consistency matter more than restrictive rules or trendy plans. Our guest is Alan Aragon, a leading expert in fitness nutrition who’s spent over 30 years coaching clients and publishing research that’s reshaped how the industry thinks about fat loss. Alongside Alan is Professor Sarah Berry, ZOE’s Chief Scientist, who brings insight from her studies on metabolism and how our bodies respond to food. Together, they unpack what actually works for long-term fat loss — and how you can get started with a realistic, effective approach that doesn’t require cutting out the foods you love.
