Understanding the Foundations
Before exploring the differences, it's crucial to acknowledge the shared foundation. Both the Healthy Eating Pyramid, developed and maintained by Nutrition Australia, and the Australian Guide to Healthy Eating (AGHE), produced by the National Health and Medical Research Council (NHMRC), are based on the 2013 Australian Dietary Guidelines. These guidelines, derived from an extensive review of over 55,000 scientific journal articles, represent the most current evidence-based advice for a healthy Australian diet. The core principles—eating plenty of plant foods, enjoying a variety from the five food groups, and limiting discretionary foods—are consistent across both tools.
Key Differences in Presentation
The primary distinction between the two guides lies in their visual format, which in turn affects their messaging and ease of interpretation.
Visual Representation and Layout
- Healthy Eating Pyramid: As the name suggests, this guide uses a tiered pyramid shape. The largest, bottom tier represents the foods to be consumed most frequently (vegetables, fruits, and grains). The middle layer contains moderate amounts of dairy and lean meats/alternatives, while the smallest top layer features healthy fats to be consumed in small quantities. Important dietary elements like water, herbs, and spices are placed alongside the pyramid.
- Australian Guide to Healthy Eating (AGHE): This guide uses a plate model, resembling a typical meal setting. The plate is divided into five segments, each representing a core food group: vegetables and legumes/beans, fruits, grains (mostly wholegrain), lean meats/alternatives, and milk/yoghurt/cheese/alternatives. The visual proportion of each segment reflects the recommended daily intake. Outside the plate, images of discretionary foods (to be limited) and healthy fats (to be used in small amounts) are shown, along with a glass of water.
Inclusion of Extra Elements
While both guides adhere to the same principles, they differ in their additional messaging.
- The Healthy Eating Pyramid explicitly includes physical activity as a foundational element, represented by the active figures climbing the pyramid. It also highlights the use of herbs and spices for flavouring instead of salt.
- The Australian Guide to Healthy Eating places a stronger emphasis on limiting 'discretionary choices' by showing them as a small, separate group away from the main five food groups. It also provides clearer guidance on healthy fats by placing them off the plate but distinguishing them from unhealthy discretionary items.
Interpretation of Proportions
The visual design of each guide influences how proportions are perceived.
- The Pyramid's tiered structure intuitively communicates frequency and amount, with the base foods being the most important. However, critics have pointed out that older versions of the pyramid could lead to misinterpretation, such as encouraging excessive grain consumption. The modern version, updated in 2013, rectifies this by increasing the focus on vegetables and whole grains.
- The AGHE's plate format provides a more direct visual representation of a single meal's composition. This can make it easier for people to apply the advice to their daily eating patterns, encouraging a focus on balancing each plate. The plate model also more clearly separates discretionary items from the core food groups.
Comparison of Healthy Eating Pyramid and AGHE
| Feature | Healthy Eating Pyramid | Australian Guide to Healthy Eating (AGHE) |
|---|---|---|
| Creator | Nutrition Australia | National Health and Medical Research Council (NHMRC) |
| Visual Model | A tiered pyramid | A divided dinner plate |
| Core Food Groups | Vegetables & Legumes, Fruit, Grains, Dairy & Alternatives, Lean Meats & Alternatives, Healthy Fats | Vegetables & Legumes, Fruit, Grains, Lean Meats & Alternatives, Milk & Alternatives |
| Physical Activity | Explicitly included as a foundational message | Not explicitly shown on the main plate graphic, though it is part of the overarching guidelines |
| Discretionary Foods | Limited salt and added sugar advised alongside the graphic | Illustrated as separate from the plate, emphasising they are not part of the core food groups |
| Healthy Fats | Positioned at the small top layer | Shown outside the plate, distinguished from discretionary foods |
| Primary Application | Shows overall dietary composition proportions | Represents the composition of a balanced meal |

Making Sense of It All
Ultimately, the choice between the two guides often comes down to personal preference for visual learning. For those who prefer a hierarchical view of dietary proportions, the pyramid might be more intuitive. It places the most important foods at the base and visually reminds you to focus on an active lifestyle. For those who prefer a more direct, meal-by-meal guide, the plate model of the AGHE may be more practical, as it helps visualise the balance of each individual meal. The AGHE's clear separation of discretionary foods is also a benefit for those needing explicit guidance on what to limit.
Conclusion
The fundamental difference between the Healthy Eating Pyramid and the Australian Guide to Healthy Eating is their visual format: the pyramid uses a tiered structure, while the AGHE uses a plate model. Despite their different appearances, both are reliable, evidence-based tools derived from the same Australian Dietary Guidelines. They share the same core nutritional principles but offer different perspectives on how to achieve a balanced diet. Neither guide is 'better' than the other; rather, they serve as complementary resources for understanding healthy eating patterns, and a person can choose whichever model best resonates with their learning style and daily habits. The ultimate goal of both remains the same: to help Australians make informed and nutritious food choices for long-term health.
