While the share of staple foods has declined in recent decades, they still represent half to three-quarters of daily energy consumption (Weinberger and others, 2009). In the Pacific islands, increasing reliance on and preference for imported, high-calorie and processed foods has resulted in changing dietary patterns. The combination of changed dietary patterns and increasingly sedentary lifestyles has led to significant increases in obesity, diabetes and other non-communicable diseases associated with changing diets (FAO, 2015; SPC, 2011).
