Obesity & The Food System
Since the 1980s, obesity prevalence in the United States has more than doubled, with approximately one-third of children and over two-thirds of adults now considered overweight or obese. Poor diet quality is the biggest contributor to obesity, with dietary behaviors shaped by the complex policies, systems, and environments in which food is produced, acquired, and consumed. Public health approaches to fighting obesity have utilized systems thinking, interdisciplinary research, cross-sectoral partnerships, effective policy, and community engagement. These tools are urgently needed to create healthy, environmentally sustainable, equitable food systems and to curb obesity trends.
