Dietary Patterns and Non-communicable Disease Prevention in Pacific Island Countries
Summary
Pacific Island countries face a growing burden of non-communicable diseases driven by rapid shifts in dietary patterns. Traditional diets that once relied on locally grown root crops, fresh fish and leafy greens have been increasingly supplanted by imported, energy-dense and ultra-processed foods. This nutrition transition has been accompanied by rising rates of obesity, type 2 diabetes and cardiovascular disease, posing major public health and economic challenges. Multifaceted strategies—ranging from community-level promotion of traditional foods to national fiscal policies—are being explored to foster healthier diets, stem the epidemic of diet-related diseases and enhance resilience in food systems. Insights into sociocultural drivers, food environments and governance structures underscore the need for integrated approaches that align agriculture, trade and health policies with the goal of preserving dietary diversity and preventing non-communicable diseases across the Pacific region.
