Urbanization is a global megatrend, with more than half the world's population living in cities. This massive demographic shift dramatically accelerates the nutrition transition, fundamentally changing what people eat and how they acquire food. These changes have profound and often contradictory impacts on human health, contributing to both a decline in undernutrition and a rapid rise in obesity.

According to the Food and Agriculture Organization, over half the world's population lives in urban areas, and this rapid demographic shift fundamentally changes how people eat. This article explores how urbanization has influenced our dietary patterns, shifting them away from traditional foods and towards more convenient options.

After World War II, innovations spurred by military rations and growing consumerism led to a rapid increase in the availability of highly processed foods, paving the way for what we now call ultra-processed food. While food processing has ancient roots, the widespread shift toward complex industrial formulations is a relatively recent development.

According to a 2015 study focusing on urban poor settings in Nairobi, 46% of children under five were stunted, while 32% of their mothers were overweight or obese, confirming the existence of a double burden of malnutrition in Kenya. This paradox of coexisting undernutrition and overnutrition represents a significant public health challenge for the country.

According to the Food and Agriculture Organization (FAO), between 2000 and 2022, the global prevalence of adult overweight rose from 30% to 43.5%, a shift driven largely by the global phenomenon known as the nutrition transition. This process involves profound changes in dietary patterns and physical activity levels as societies experience economic development and urbanization.

According to Statistics Canada, the adjusted self-reported obesity rate for adult Inuk (Inuit) people in 2021-2022 was 43.6%, significantly higher than the 29.2% for non-Indigenous people during the same period. Understanding what is the obesity rate for the Inuit people requires examining a complex web of interconnected social, economic, and environmental factors.

According to UNICEF, more school-aged children and adolescents worldwide are obese than underweight for the first time in history. This dramatic and unsettling milestone underscores the complex and often paradoxical nature of today's global food crisis, where issues of scarcity and excess coexist.

According to the World Health Organization, nearly half of all countries face the serious burdens of malnutrition, which includes both undernutrition and adult overweight. This public health paradox, known as the double burden of malnutrition, is driven by a complex interplay of environmental, social, economic, and physiological factors that often exist concurrently. Understanding the root causes of double malnutrition is crucial for developing effective, integrated strategies to address this growing global health challenge.

Research consistently shows that immigrants and their children gain weight after moving to the United States. Often arriving with healthier pre-migration body mass indexes (BMIs), many individuals experience a significant and measurable increase in weight due to adapting to the new 'obesogenic' American environment. This phenomenon is driven by a complex mix of dietary changes, shifts in lifestyle, and cultural adaptation.

According to the Pan American Health Organization (PAHO), the prevalence of overweight and obesity among Haitians aged 15 and older was 29.9% in 2022, with this figure reportedly rising to 54.9% in 2023. Understanding the obesity rate in Haiti requires examining the complex interplay of severe food insecurity, socioeconomic factors, and a changing dietary landscape. This growing public health concern reveals a complicated paradox where undernutrition and excess weight are both significant issues.
