A Tale of Two Pyramids: MyPyramid vs. the Mediterranean Diet
For years, the U.S. Department of Agriculture (USDA) guided Americans with its Food Guide Pyramid, which was later updated to MyPyramid in 2005. At the same time, the Mediterranean Diet Pyramid, developed by Oldways and the Harvard School of Public Health, was gaining international recognition for its association with health benefits. While both were designed as visual aids for healthy eating, they conveyed fundamentally different philosophies and recommendations, particularly in their approach to specific food groups.
Understanding the MyPyramid Model
MyPyramid, with its vertical colored stripes and an ambiguous figure running up a staircase, was a departure from its predecessor. The colored bands represented different food groups, with the width of each band indicating the recommended proportion of the diet. However, it notably lacked explicit guidance on portion sizes, instead directing users to a website for personalized advice, which made it less intuitive for many. MyPyramid's base was not a specific food group but a representation of individual energy needs and physical activity. The food groups it included were grains, vegetables, fruits, milk, and meat & beans. Crucially, its 'Meat & Beans' category made no distinction between red meat and healthier protein sources like fish or legumes, and its 'milk' category gave significant prominence to dairy products.
Decoding the Mediterranean Diet Pyramid
The Mediterranean Diet Pyramid, in contrast, is an unambiguous representation of the traditional dietary patterns observed in countries surrounding the Mediterranean Sea. Its recommendations are based on food groups, with the frequency and portion size decreasing as you move up the pyramid. The base of the pyramid emphasizes a lifestyle, not just food, including daily physical activity, social meals, and hydration. The food recommendations begin with a broad base of daily plant-based foods, olive oil, and herbs.
What is one of the ways that the Mediterranean Diet Pyramid recommendations differ from MyPyramid?: A Focus on Fat
One of the most significant and well-documented differences between the two diet pyramids lies in their approach to dietary fats. The Mediterranean Diet Pyramid explicitly champions extra virgin olive oil as the primary source of fat, and recommends it for daily consumption. It encourages the consumption of healthy, monounsaturated fats from olive oil, nuts, and seeds, which are associated with cardiovascular benefits. In contrast, MyPyramid grouped all fats together, including unhealthy saturated and trans fats, in a tiny band of yellow, recommending they be limited. This lack of differentiation meant that healthy fats were not given the specific prominence and encouragement they deserved, and the overall message could be misinterpreted as all fats being equally bad.
Contrasting Dairy and Red Meat Recommendations
Beyond fats, the pyramids also have vastly different recommendations for dairy and red meat consumption. MyPyramid allocated a significant portion of its vertical space to the 'milk' group, promoting its daily consumption. The Mediterranean Diet, however, recommends a much lower intake of dairy products, primarily in the form of cheese and yogurt, consumed daily to weekly in moderate amounts. For many people in the Mediterranean region, traditional goat and sheep milk products are more common than cow's milk, which may be more challenging for some to digest.
The most striking difference, however, is in the protein recommendations. MyPyramid grouped all meat, poultry, fish, and legumes into a single, prominent 'Meat & Beans' category, allowing for a high intake of red meat. The Mediterranean Diet Pyramid, on the other hand, places red meat at the very top, recommending it only a few times per month. It promotes weekly consumption of fish and seafood, with poultry and eggs consumed moderately per week. This shift away from red meat towards fish, a rich source of omega-3 fatty acids, is a major contributing factor to the diet's cardiovascular benefits.
Other Key Differences Between the Pyramids
- Emphasis on Lifestyle: Unlike MyPyramid, the Mediterranean Diet Pyramid places daily physical activity, social dining, and mindful eating at its foundation, framing diet within a broader healthy lifestyle.
- Flexibility and Customization: The Mediterranean diet is a cultural model rather than a rigid set of instructions, allowing for adaptation based on local, seasonal, and fresh foods. MyPyramid was less adaptable and relied on its website for specific, quantitative recommendations.
- Visual Clarity: The Mediterranean Diet Pyramid's tiered structure more clearly communicates the frequency and proportion of different food groups, while MyPyramid's vertical stripes were less intuitive.
Comparison Table: Mediterranean Diet Pyramid vs. MyPyramid
| Feature | Mediterranean Diet Pyramid | MyPyramid (USDA, 2005) |
|---|---|---|
| Foundation | Daily physical activity, social meals, hydration | Individual energy needs, physical activity |
| Primary Fat Source | Healthy fats, especially olive oil, nuts, and seeds | All fats grouped, with recommendation to use sparingly |
| Dairy Recommendation | Low to moderate intake (mostly cheese, yogurt) | Daily intake, with significant prominence |
| Red Meat Recommendation | Limited to a few times per month | Prominent part of 'Meat & Beans' category |
| Plant-Based Focus | Broad base of vegetables, fruits, whole grains, legumes | Vegetables, fruits, and grains included but less emphasized |
| Protein Emphasis | Fish and seafood recommended weekly; red meat limited | All meat, beans, poultry, and fish grouped together |
| Information Delivery | Visual guide, culturally based, adaptable | Vertical stripes directing users to a website |
Conclusion
When asking what is one of the ways that the Mediterranean Diet Pyramid recommendations differ from MyPyramid?, the answer is multi-faceted, but most significantly, it is in their distinct approach to food categorization and prioritization. The Mediterranean Diet Pyramid offers a clearer, more holistic, and health-focused approach by championing healthy fats, a broader plant-based intake, and explicitly limiting red meat and dairy, a stark contrast to MyPyramid's less specific and more dairy/meat-centric recommendations. This difference is not merely a matter of visual design but reflects fundamental variations in nutritional philosophy that have significant implications for long-term health.
