Remember when low-fat crazes ruled, carbs were king, and the food pyramid looked completely different? 

In this special National Science Week episode of Nutrition Decoded, Brent sits down with registered nutritionist Dr Emma Beckett to take a fascinating look back at the history of the Australian Healthy Eating Pyramid. We explore how nutritional science has evolved over the decades, why official guidelines constantly update in response to new health data, and what we should actually be putting on our plates today.

• The Origins of Dietary Guides: Tracing how visual food guides evolved from early wartime rationing tools into modern public health models.

• The Australian Pivot: How modern iterations of the food pyramid have refined their tiers away from heavy grain bases to prioritize vegetables, legumes, and quality proteins.

• Science in Motion: Why nutritional recommendations shift as researchers uncover more about chronic disease, gut health, and metabolism.

• Back to Basics: Cutting through restrictive fad diets to focus on balanced, sustainable, whole-food eating patterns built around the five core food groups.

If you want a science-backed, gimmick-free look at how we eat and why nutritional advice changes, this is an absolute must-listen.
