Chapter 9 of the Health Effects of Climate Change (HECC) in the UK: 2023 report. The chapter reveals 2 key public health insights. Firstly, the UK is already reliant on imports for a range of foods that align with a healthy diet, and the proportion of our foods that come from climate-vulnerable countries is increasing. As the climate warms and impacts are felt, this is likely to mean that food imports and prices will be more volatile. This may further constrain consumption of healthy foods and prevent people from meeting dietary recommendations. Secondly, many healthy foods are associated with lower greenhouse gas emissions. For example, red meat typically generates more greenhouse gas emissions than many plant-based foods, so there are substantial potential co-benefits to health from switching to a healthier diet. Supply of both home-grown and imported fruit, vegetables and legumes will need to increase to meet the UK’s dietary and health requirements, but there are potential risks arising from climate-related reductions in yields elsewhere.
