Summary
This narrative review synthesises evidence on the escalating global trend of meat consumption driven by rising incomes and population growth, examining its dual impacts on human health and environmental sustainability. The authors explore the health trade-offs—noting that whilst meat provides concentrated nutrition for low-income populations, increased consumption elevates risks of chronic diseases including colorectal cancer and cardiovascular disease—alongside substantial environmental costs from land and water use. The paper emphasises the need for integrated natural and social science approaches to develop effective policies addressing meat consumption patterns.
UK applicability
The findings are broadly applicable to UK policy and public health contexts, where meat consumption and related chronic disease burdens are significant. However, the review's global scope means specific recommendations would require contextualisation to UK dietary patterns, agricultural systems, and policy levers.
Key measures
Global per capita meat consumption trends; health risks associated with meat consumption; environmental impacts of livestock production; policy intervention effectiveness
Outcomes reported
The paper reviews evidence on rising global meat consumption patterns, their health effects (including increased risk of colorectal cancer and cardiovascular disease), and major environmental consequences for land, water use, and climate. It examines policy interventions and social factors influencing meat consumption habits.
