Dietary guidance varies by country, and no international food pyramid has brought its recommendations together until now. BYU nutritional science professor Karen Della Corte led a global team of nutrition scientists to develop an International Food Guide Pyramid that reflects broad scientific agreement and can be adapted across cultures and borders.

With the International Carbohydrate Quality Consortium, Della Corte compared national and regional dietary guidelines from Canada, Germany, Australia, China and the Nordic countries. She also synthesized evidence from more than 250 scientific publications and drew on the EAT-Lancet Planetary Health Diet to identify shared principles of healthy eating.

"Despite what people often hear, there's actually substantial agreement in nutrition science about the foundations of healthy eating," Della Corte said. "We wanted to bring those shared principles together and translate an extensive body of scientific evidence into a coherent and practical food guide pyramid."

The pyramid emphasizes plant-based proteins but does not exclude animal foods. It can also be adapted for vegetarian and vegan diets.

The EAT-Lancet Commission suggests that adopting its proposed healthy, plant-forward diet could prevent approximately 15 million premature deaths each year. Such changes could also reduce greenhouse gas emissions and other environmental impacts associated with livestock farming.

"Our diet has to be not only for our own health but also for the health of our planet," said David Jenkins of the University of Toronto, creator of the glycemic index.
