Showing results for: Dietary guidelines
Although there is no absolute consensus on the recommendation for total fat and dietary fat and saturated fat (SFA) intake between governing bodies and health organizations, there is a general sense of convergence. All guidelines currently suggest that total fat should not exceed 35% of daily calories. Although most guidelines propose a target for dietary SFA, there is no consensus on the value to aim for.
BBSRC - Biotechnology and Biological Sciences Research Council has released a report on sustainable intensification (SI) together with an invitation for interested parties to comment. Responses received will be taken into account in addressing the group’s recommendations.
The European Commission was due to publish a Communication on Sustainable Food in 2013 to “assess how best to limit waste throughout the food supply chain, and consider ways to lower the environmental impact of food production and consumption patterns”. This long-awaited Communication has still not been published.
The annual report 2013 from Bioversity international contains a special discussion on “Improved nutrition through sustainable food choices”.
The sustainable diets research by Bioversity focuses on food and food systems, taking into account food diversity and how it can be produced and acquired across all seasons and under different economic circumstances.
This paper provides a schema for categorizing all diets as either: low carbohydrate; fat, low glycemic; Mediterranean; mixed, balanced; Paleolithic; or vegan. The researchers emphasize that the aim of the research is not to recommend one particular diet over another, but rather to highlight how disease prevention and increased public health is best realised.
This paper looks at the environmental costs of food production and consumption. It offers an updated account of the GHG emissions associated with production of U.S. food losses at the retail/institution and consumer level and also considers the effects of a shift in diets away from current US consumption patterns towards those recommended by USDA dietary guidelines.
The next version of Dietary Guidelines for Americans, from the U.S. Department of Agriculture (USDA) and the Department of Health and Human Services (HHS) seem likely to include advice on sustainable diets. Preliminary conclusions from a subcommittee on food sustainability and safety indicate that the message of how the food is produced will be included in the final recommendations. For more on these subcommittee discussions read an article in Science here.

The Centre for Alternative Technology (CAT) has launched a new report on sustainable diets - People, Plate and Planet, describing dietary choices that can reduce greenhouse gas emissions and pressures on land. The report considers nutrition, GHG emissions and land use and states that the most significant impact on these areas comes from what we eat, not where it is from or how much packaging there is around it.
This paper provides a review of the current literature analysing environmental impacts of dietary recommendations. The review focuses on three aspects of dietary advice in particular: reducing the consumption of fat, reducing the consumption of meat-based protein and animal-based foods, and finally increasing the consumption of fruit and vegetables. It then reviews the environmental impact assessments and Life Cycle Analysis (LCA) that have been undertaken in foods that have relevance to these three dietary recommendations.
