Consumer diet and behavior are critical contributors to the sustainability of the food system. The Ten Principles discussed in this book identify the key sustainability needs across the supply chain, and they offer exciting potential to shift from a system that depletes to one that improves the economy, environment, and society. The Barilla Center for Food and Nutrition (BCFN) developed the Double Pyramid to illustrate that diets based on higher consumption of fruits, vegetables, and grains, and just a moderate consumption of animal products are both good for health and the environment. A sustainable food system is critically needed and requires action from all contributors in the supply chain. Producers, processors, distributors, marketers, and consumers play a role in implementing solutions that produce more food without compromising society or the environment on the same amount of land and reduce food demands, especially for resource-intensive foods.
