A History of Dietary Guidance: From Pyramids to Plates
The U.S. Department of Agriculture's (USDA) dietary guidance has evolved significantly over the past century to reflect advancing nutritional science. The journey began long before MyPlate, with guides like the 'Basic 7' during World War II. However, the most recognizable predecessors to MyPlate were the various versions of the food pyramid.
The original Food Guide Pyramid was introduced in 1992, representing food groups in horizontal sections. It was eventually criticized for its complexity and the placement of high-carbohydrate grains at its broad base.
In response to this feedback and new scientific understanding, the USDA launched MyPyramid in 2005. This version featured abstract vertical stripes representing the food groups, which critics found even more confusing. A small figure climbing steps on the side also indicated the importance of physical activity.
Finally, the simplified and more intuitive MyPlate icon was introduced in June 2011. It visually divides a dinner plate into four colored sections for fruits, vegetables, grains, and protein, with a separate circle for dairy, making portioning easy to understand.
The Dietary Guidelines for Americans: The Real Update Cycle
While the MyPlate icon itself has remained the same since 2011, the nutritional science it is based on is regularly updated every five years through the Dietary Guidelines for Americans (DGA). These guidelines form the basis for all federal nutrition programs and advice. The most recent DGA document is the 2020-2025 edition, which was released in late 2020. Key themes from the 2020-2025 guidelines that inform the MyPlate approach include:
- Emphasizing variety: Acknowledging the need for a wide range of nutrient-dense foods from all five food groups.
- Focusing on dietary patterns: Shifting the focus from individual nutrients to overall healthy eating patterns over time.
- Life stage considerations: Providing guidance tailored to specific life stages, from infants and toddlers to older adults.
- Customization: Encouraging individuals to build their own healthy eating plan based on personal preferences, cultural food traditions, and budget.
MyPlate vs. MyPyramid: A Comparison of Approaches
| Feature | MyPyramid (2005) | MyPlate (2011) |
|---|---|---|
| Visual Representation | Vertical color-coded stripes of varying widths. | Simple place setting with a divided plate and a glass. |
| Food Proportions | Proportions indicated by stripe width; not immediately clear what percentage of a meal each group should represent. | Proportions are immediately apparent by the size of the sections on the plate. |
| Clarity | Often criticized as confusing and abstract without additional educational materials. | Designed to be simple, clear, and easy to understand at a glance. |
| Key Focus | A website and an 80-page document provided context; emphasized activity. | Easily understood visual reminder of balanced portions, focusing on what should be on the plate. |
| Missing Elements | It did not have specific recommendations for individual nutrients or portion sizes on the graphic itself. | Does not explicitly mention oils, fats, or sugars, though the website provides this detail. |
Ongoing Refinements and Resources
The MyPlate website is a dynamic resource, constantly updated with new tools, articles, and tips for healthy eating, even though the central icon remains unchanged. For example, the site offers the "MyPlate Plan," which provides a personalized eating plan based on a user's age, sex, weight, height, and activity level. The platform also offers seasonal guides and budget-friendly tips. This online ecosystem provides the real, ongoing updates to the MyPlate guidance.
What the 2020-2025 Guidelines Advise
The DGA 2020-2025 emphasizes the following key principles to align with the MyPlate model:
- Follow a healthy dietary pattern at every life stage: This includes guidance for pregnant and lactating women and recommendations for toddlers.
- Customize and enjoy nutrient-dense foods and beverages: Emphasizes cultural and personal preferences, allowing for flexibility while focusing on core principles.
- Focus on meeting food group needs with nutrient-dense foods: Prioritizes foods that provide vitamins, minerals, and other healthy substances with little saturated fat, added sugars, and sodium.
- Limit foods and beverages higher in saturated fat, sodium, and added sugars: While MyPlate doesn't show these explicitly, the guidelines reinforce their moderation.
Conclusion
So, while the MyPlate visual itself has not been physically updated since its release in 2011, the dietary advice it is based on is regularly refined and presented to the public through the comprehensive Dietary Guidelines for Americans. The icon serves as a timeless, user-friendly symbol, while the supporting online resources provide the continuously evolving, science-based information necessary for a healthy diet. This dual-pronged approach ensures that MyPlate remains a relevant and easy-to-understand tool for American consumers, with the most recent major update to its foundation occurring in 2020.
An Important Distinction: MyPlate vs. Other Guides
It's important to differentiate MyPlate from other nutrition guides that have been developed by different organizations, such as the Harvard Healthy Eating Plate or the Mediterranean diet plate. These models may offer slightly different recommendations based on their own research or focus. The USDA's MyPlate is the official federal guide and is the basis for many government-run nutrition programs and educational materials. It is this model that is regularly refined every five years through the DGA process, even if the graphic remains the same. For instance, a recent University of Florida blog post in 2025 noted the differences between the MyPlate and Mediterranean dietary approaches.

A Final Word on the Future of MyPlate
The simplicity and effectiveness of the plate-based visual have proven more enduring than its pyramid-shaped predecessors. By decoupling the icon from the specifics of the dietary advice, the USDA has created a system that can be updated more easily. While we may not see a new graphic in the coming years, we can expect the science-backed advice behind it to continue evolving with each new edition of the Dietary Guidelines for Americans. The next update is expected around 2025, continuing the cycle of refinement without necessarily changing the familiar plate image.
