Which is Better for Reducing Food Waste: Nutrition or Sustainability?

Recent research has examined whether food waste is more effectively reduced by consumers motivated by sustainability or those focused on nutrition and health. The study’s surprising results emphasize the importance of reevaluating our strategies for tackling food waste.

Dr. Trang Thi Thu Nguyen, lead author of the study, said, “Consumers aware of sustainability tend to waste less food as they seek eco-friendly products. However, those focused on sustainability often prioritize product selection over reducing food waste.”

Survey on Food Consumption Behavior and Waste

The researchers surveyed 1,030 adults online about household food consumption, asking, “It is important to me that the food I consume:”, followed by eight items on nutrition or sustainability. They rated these statements on a seven-point scale ranging from strongly disagree to strongly agree. For example, a nutrition-related statement was, “The food I consume keeps me healthy,” and a sustainability-related statement was, “The food I consume is packaged in an environmentally friendly way.” After defining food waste and listing its categories, participants estimated their total food waste.

Upon analyzing the data, the researchers found that a focus on nutrition was significantly and negatively associated with food waste. “Additionally, individuals who prioritized nutrition showed a positive link to meal planning behaviors and a negative association with over-purchasing.”

Nguyen noted, “Individuals who focus on healthy eating tend to plan meals and avoid over-purchasing, which helps reduce food waste significantly.”

The researchers stated that their findings suggest a shift in perspective is necessary for effectively addressing food waste on a societal scale.

Nguyen suggested, “Future food waste campaigns should link nutrition and waste reduction, as people are more motivated by health benefits than abstract environmental concerns, making it a more convincing part of a healthy lifestyle.”

“However, the researchers also pointed out that their study highlights actions households can take to reduce food waste.”

Nguyen said, “This will help households save money on food waste, especially during a cost-of-living crisis, while promoting healthier eating habits. A sustainable food system is about how we manage, prepare, and consume food, not just choosing the right products.”
