Participation in a one-unit Foodprint seminar significantly increases vegetable intake and decreases ruminant meat consumption, resulting in a 14% reduction in dietary carbon footprint among college students.

To reduce your dietary carbon footprint, consider taking a course or workshop focused on food systems and sustainability. This specific 'Foodprint' model uses active learning to help you calculate the environmental impact of your food choices. The result is a measurable increase in vegetable consumption and a decrease in ruminant meat (beef/lamb) and sugar-sweetened beverages, leading to a significant reduction in your dietary carbon footprint.

ModerateSupportsMEDIUM confidence
Students who took the Foodprint seminar significantly improved their reported vegetable intake by 4.7 weekly servings relative to the comparison group. They also reported significantly decreasing intake of ruminant meat and sugar-sweetened beverages. As a result of dietary shifts, Foodprint seminar students were estimated to have significantly decreased their dietary carbon footprint by 14%.
