A team of 22 nutrition scientists from Europe, North America, and Australia has published a standardized international nutrition pyramid in the journal Advances in Nutrition. The model aims to reconcile divergent national dietary guidelines into a single framework based on modern health and environmental data.
The project, led by Professor Karen Della Corte of Brigham Young University, was developed without external funding. To create the model, researchers analyzed official dietary recommendations from seven regions—Canada, Germany, Australia, China, the Netherlands, the United States, and the Nordic countries—alongside findings from more than 250 specialist publications.
Core Pillars of the Proposed Dietary Model
The researchers structured the pyramid around three primary nutritional pillars. At the foundation are plant-based foods, which the authors identify as the largest component of a healthy diet. This base is supported by the intake of high-quality fats and proteins, with a specific emphasis on the biological quality of carbohydrates.
Rather than advocating for the total exclusion of animal products, the model permits the consumption of lean animal proteins. However, the researchers prioritize legumes, nuts, poultry, fish, and eggs over red and processed meats. For fat sources, the pyramid focuses on unsaturated plant oils, such as olive oil, while recommending the minimization of saturated fats and refined sugars.
Regarding carbohydrates, the scientists advocate for prioritizing fiber content, low levels of processing, and a favorable glycemic index. This approach favors whole-grain products over refined cereals and sugar-sweetened beverages. According to Professor Della Corte, the consistent adoption of this plant-forward diet could potentially prevent approximately 15 million premature deaths globally each year, a figure cited in reference to the EAT-Lancet Commission’s Planetary Health Diet.
Divergence in International Dietary Policy
The new model highlights significant contrasts in current global nutrition policies. While Laura Rossi of the Istituto Superiore di Sanità notes that the proposed structure aligns closely with traditional approaches like the Mediterranean diet, other national policies remain distinct.
The U.S. dietary guidelines for 2025–2030, currently under discussion, show a marked departure from the researchers’ model. These upcoming U.S. guidelines place a greater emphasis on animal proteins, including red meat, and classify fats such as butter and beef tallow as preferred dietary fats. The international team’s proposal functions as a counter-model, advocating for global standardization centered on minimally processed, plant-based foods.
Common Questions About the Global Nutrition Model
How does this model differ from existing national guidelines?
While many national guidelines emphasize similar health goals, they often vary in their specific treatment of animal versus plant-based proteins and the classification of healthy fats. The new model seeks to harmonize these differences by prioritizing plant-based foundations and specific carbohydrate quality over the diverse recommendations currently found in individual national standards.
What role does environmental health play in these recommendations?
The model integrates findings from the EAT-Lancet Commission’s Planetary Health Diet, which links human dietary choices to environmental sustainability. The researchers argue that shifting toward the proposed plant-forward pattern addresses both individual health outcomes and broader ecological objectives.
Is this model intended to replace national dietary rules?
The researchers present the pyramid as a scientific draft and a common standard based on global consensus rather than a mandatory replacement for national policy. It serves as a synthesis of data from seven regions and over 250 specialist publications, designed to highlight a unified approach to nutrition amidst varying international political stances.
