Brigham Young University nutritional scientist Karen Della Corte has collaborated with 22 nutrition researchers from around the world to create an International Food Guide Pyramid, according to a report published on October 22, 2026, by BYU News. Published in the journal Advances in Nutrition, the new framework translates complex academic nutrition data and varied national standards into a unified, accessible dietary tool that can be adapted across different borders and cultures.
While dietary guidance traditionally varies from country to country, the international research team worked to unite shared scientific principles into a single visual model. Working alongside the International Carbohydrate Quality Consortium, Della Corte and her colleagues analyzed and compared national and regional dietary guidelines from the United States, Canada, Germany, Australia, China, the Netherlands, and the Nordic countries. To build the guide, the researchers synthesized findings from more than 250 scientific publications and incorporated concepts from the EAT-Lancet Planetary Health Diet.
Bridging Global Nutrition Standards
Public perception often suggests that nutrition advice is constantly shifting or contradictory. However, Della Corte noted in the university report that strong scientific consensus actually exists regarding the core foundations of a healthy diet. The research team aimed to gather those shared principles and convert a large body of peer-reviewed evidence into a practical, everyday structure for consumers and health educators.
Rather than prescribing a rigid meal plan tied to one specific region's agriculture or culinary habits, the International Food Guide Pyramid focuses on broad food groups and nutritional quality. At its base, the pyramid places vegetables, fruits, and whole, low-glycemic-index grains as the primary building blocks of daily meals. While the structure emphasizes plant-based proteins and plant oils, it does not eliminate animal-derived foods. The framework is intentionally flexible, allowing individuals and public health agencies to adapt it for omnivorous, vegetarian, or vegan eating patterns depending on personal preference and cultural traditions.
The Three Core Pillars of the Global Guide
To keep the academic data straightforward for everyday decision-making, the researchers organized the pyramid around three primary dietary recommendations:
- Make plant foods the foundation of a healthy diet: Daily meals should center on whole vegetables, fruits, legumes, and minimally processed grains.
- Choose healthier sources of fat and protein: The guide favors plant-based proteins and unsaturated plant oils while advising consumers to limit processed meats.
- Prioritize carbohydrate quality: Rather than cutting out carbohydrates, individuals are encouraged to select fiber-rich, slow-digesting options while minimizing refined grains and sugary sodas.
A major focus of the new guide is helping the public distinguish between different types of dietary fats and carbohydrates. The pyramid separates saturated fats—commonly found in butter, cream, and fatty meats—from unsaturated fats derived from plant oils. According to Della Corte, substituting unsaturated plant oils in place of saturated fats supports long-term cardiovascular health.
Similarly, the international panel stressed that carbohydrates should be evaluated by their structural quality rather than treated as a single uniform category. In the guide, carbohydrate quality is measured by dietary fiber content, the degree of industrial food processing, the natural structure of the food, and its glycemic index—a metric that tracks how quickly a carbohydrate-containing food raises blood glucose levels.
Anette Buyken, a professor at Paderborn University in Germany who contributed to the project, explained in the BYU News release that because carbohydrate-rich foods supply a large share of daily human energy for both health and environmental sustainability reasons, paying close attention to how those foods affect blood glucose alongside their fiber and sugar content is especially important.
Linking Personal Nutrition and Planetary Health
Beyond individual clinical outcomes like blood sugar management and heart health, the International Food Guide Pyramid integrates environmental sustainability into its nutritional framework. By drawing on the EAT-Lancet Planetary Health Diet, the researchers accounted for how global food production affects the environment.
According to estimates from the EAT-Lancet Commission cited by the research team, shifting global eating habits toward a plant-forward diet could prevent approximately 15 million premature deaths annually while simultaneously lowering greenhouse gas emissions and other environmental pressures tied to industrial livestock farming. David Jenkins of the University of Toronto, who created the glycemic index and participated in the research, emphasized that modern dietary guidance must support both human wellness and the health of the planet, requiring a science base broad enough to address both needs.
This effort to make academic nutrition data more practical for the public aligns with broader public health movements connecting daily diet to long-term wellness. In a separate scientific report published via Newswise, microbiome researchers led by Rutgers University scientists Martin Blaser and Maria Gloria Dominguez-Bello recently outlined a proposal in Nature Medicine examining how diets heavy in highly processed foods can disrupt the human microbiome—the trillions of microorganisms that help regulate human metabolism and immunity. That panel recommended aligning nutrition science with medical training and school nutrition education so that academic findings can directly inform everyday dietary choices, particularly during pregnancy and early childhood.
What This Means for Everyday Meal Planning
For American consumers navigating crowded grocery aisles and conflicting dietary trends, the International Food Guide Pyramid offers a streamlined checklist rooted in international agreement. Instead of counting complex macros or eliminating entire food groups, readers can apply the researchers' findings through simple kitchen substitutions:
- Swap cooking fats: Use liquid plant oils instead of butter or cream when preparing daily meals to reduce saturated fat intake.
- Upgrade grain choices: Replace refined white bread, white rice, and sugary breakfast items with intact whole grains and fiber-rich foods that have a lower glycemic index.
- Rethink beverages and meats: Cut back on sugary sodas and processed meats, shifting the center of the plate toward beans, lentils, vegetables, and whole fruits while treating animal proteins as a smaller accompaniment.
How does the guide evaluate carbohydrate quality?
Rather than treating all carbohydrates the same, the pyramid evaluates them based on four specific factors: natural fiber content, how heavily the food has been processed, the physical structure of the food, and its glycemic index, which measures how the food impacts blood glucose levels.
Does the International Food Guide Pyramid require a vegan or vegetarian diet?
No. While the pyramid places plant foods at its base and encourages plant-based proteins and oils, it does not exclude animal foods. It is designed as a flexible template that can be used by people who eat meat as well as those who follow vegetarian or vegan diets.
Which national dietary guidelines were reviewed to create this pyramid?
The research team compared national and regional dietary standards from the United States, Canada, Germany, Australia, China, the Netherlands, and the Nordic countries, alongside data from more than 250 scientific publications.
