Showing results for: Food nutrients
The book Sustainability of the Food System: Sovereignty, Waste, and Nutrients Bioavailability addresses food sustainability through the lens of food sovereignty, environmentally friendly food processes, and food technologies that increase the bioavailability of bioactive compounds.
This narrative review paper explores how understanding of nutrition and public health have changed over time, influenced by developments in science, social changes and policy-making. The paper identifies some major paradigm shifts, such as the identification of vitamins in the early 20th century, and the recognition of the link between dietary patterns and some chronic diseases in the late 20th century.
Two letters in the journal Cell Metabolism respond to the recent paper by Hall et al., Ultra-Processed Diets Cause Excess Calorie Intake and Weight Gain: An Inpatient Randomized Controlled Trial of Ad Libitum Food Intake. See our Building Block on disagreements about ultra-processed foods here: What is ultra-processed food? And why do people disagree about its utility as a concept?
This report from UK supermarket Sainsbury’s sets out predictions for how the food system might be in the years 2025, 2050 and 2169. Near-term predictions include milk made from algae, and increased numbers of flexitarian eaters, while long-term predictions include farming in inhospitable landscapes such as deserts or Mars, and personal microchip implants that tell us exactly what nutrition we need.
This paper sets out a new method to account for nutrition in the functional unit of life cycle assessments of single foods. The method accounts for the wider dietary context of each food type, which is found to affect the results relative to using either mass as a functional unit, or another nutrient-based functional unit that does not consider the dietary context.
This perspective piece argues that the definition of protein quality should be updated to reflect both environmental and nutritional concerns.
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.
