This paper by FCRN member Elinor Hallström assesses the nutritional content and climate impact of 37 seafood products. The paper finds high variability in nutritional and climate performance, with no consistent correlation between nutrition and climate impact across different seafood species. The paper calls for dietary advice to promote species with low climate impact and high nutritional value, including sprat, herring, mackerel and perch.

According to this randomised controlled trial, people eat an average of 500 kcal more per day when offered ultra-processed food compared to unprocessed food (as defined by the NOVA system). Furthermore, the trial subjects gained weight on the ultra-processed diet and lost weight on the unprocessed diet.

This paper by FCRN member Claire Pulker of Curtin University analyses the presence and quality of supermarket corporate social responsibility (CSR) policies related to all attributes of public health nutrition, including sustainability. The paper audited Australian supermarket own brand foods to establish the extent to which CSR policies are translated into practice.

This paper evaluates the impact of diet on risk factors for heart disease. It finds that replacing red meat with “high-quality” plant protein sources (such as legumes, soy or nuts), but not with fish or “low-quality” carbohydrates (such as refined grains and simple sugars), results in improvements in total and low-density lipoprotein cholesterol.

This paper assesses the agricultural water use efficiency of different food types based on their nutrient content, instead of the conventional approach of assessing water use in terms of litres used to produce a certain weight of food. The purpose of the study is to determine whether higher intakes of nutrient-rich foods such as fruit, vegetables and seeds might conflict with the aim of minimising agriculture’s water use.

FCRN member Christian Reynolds uses linear programming to calculate diets that meet both health and greenhouse gas emission criteria while being affordable for different income groups in the UK. Generally, the optimised diets are higher in plant-based foods than diets consumed in the UK in 2013, although seafood is higher in the optimised diet than in 2013 diets.

This report from the UK think tank, the Food Foundation identifies ten statistics that illustrate the effect that the UK’s food system has on health, and makes recommendations aimed at ensuring that healthy diets are accessible to all.

FCRN member Diego Rose has written a paper on the links between dietary choices in the United States (based on real dietary data), environmental impacts, and nutrition quality, finding that the diets with the lowest greenhouse gas emissions per calorie generally scored better on the US Healthy Eating Index.

Insects, seaweed, microalgae, cultured meat, mycoprotein and mussels are among the nine ‘future foods’ discussed in this paper, co-authored by FCRN members Hanna Tuomisto and Hannah van Zanten, which compares the nutritional profiles and environmental impacts of these foods with conventional plant- and animal-sourced foods.

The global supermarket sector's commitments to protect public health are “generally disappointing”, finds FCRN member Claire Pulker of Curtin University. However, some progress is being made address food waste, assure food safety and quality, and support selection of healthy foods.

The Association of UK Dietitians (BDA) has released a toolkit for environmentally sustainable diets, which contains information on eating patterns for health and environmental sustainability, a glossary, frequently asked questions and a list of meal swaps.

This report finds that the ten largest US food and beverage manufacturers lack comprehensive strategies for effectively addressing obesity and diet-related diseases. Assessing a portfolio of the manufacturers’ products, the report classifies only 30% as “healthy”.

A global model of how child stunting could be affected by climate change and poverty in 2030 has been developed by FCRN member Simon Lloyd of the London School of Hygiene and Tropical Medicine. By 2030, an estimated 570,000 to over one million children under 5 will suffer from stunting that can be attributed to climate change, with both greater poverty and greater climate change causing more stunting.

Current crop production levels could feed a population of 9.7 billion people in 2050, according to a recent paper, but only in a future in which there are socio-economic changes, significant shifts in diets towards plant-based foods, and limited biofuel production. Without dietary changes, crop production would have to increase by 119% by 2050.

Rob Bailey and Bernice Lee of UK think tank Chatham House have written a piece exploring food system trends, including rising food demand, plateauing yields in key crop production regions, global convergence on a diet dependent on calorie-dense but nutrient-poor crops and a lack of genetic diversity in staple crops. The authors conclude that current food system trends are unsustainable, saying, “The continued intensification and expansion of agriculture is a short-term coping strategy that will eventually lead to food-system collapse.” They call for interventions at key leverage points in the food system.
