A recent analysis by Stylianou et al. (2021) estimated the impact of small dietary changes in the consumption of individual foods on human health and the environment, expressed as minutes of healthy life lost or gained daily and dietary carbon footprint, respectively. While an appealing concept for its simplistic interpretation, we propose that this analysis is unwarranted based on existing evidence and produces results that fail to recognize the importance of essential nutrient density and disregard the risks associated with ultra-processed foods, sugar, and refined starches. The environmental impact assessment undoubtedly adds novelty to the growing field of nutritional-life cycle assessments; however, the use of “ready-made” environmental systems is concerning when drawing such decisive conclusions. We therefore caution against use of this food classification system to inform consumer choices, front-of-package labelling, policies, and programs. |
