What Should the Western Food System Look Like? Papua New Guinea’s Diet Is a Start

The Western food system, characterized by industrialized agriculture and processed foods, is contributing to rising rates of obesity, diabetes, and heart disease. In contrast, the diet of rural Papua New Guinea is predominantly plant-based, high in fiber, and low in sugar and calories. Research shows that people in Papua New Guinea are healthier, with lower cholesterol levels and inflammation, likely due to their plant-led diet.

To promote gut health and increase fiber intake, researchers have created the NiMe diet, based on the Papua New Guinea diet. This diet emphasizes whole plant-based foods and high amounts of fiber, with participants experiencing drops in cholesterol and inflammation. However, adopting a diet similar to Papua New Guinea's is challenging in Western markets dominated by industrialized food systems. Additionally, reducing meat consumption is vital to meeting climate goals and protecting the environment, as industrial agriculture is a leading cause of greenhouse gas emissions and deforestation.
