One Blue Dot: Environmentally Sustainable Diet Toolkit

One Blue Dot Banner

What is One Blue Dot?

One Blue Dot is the BDA's Environmentally Sustainable Diet Project, created to help make our Sustainable Diets Policy a reality. On these pages you will find a toolkit of information, graphics, tools and links to help you improve your understanding of environmentally sustianable diets and discuss these with your patients or clients. This is very much a "live" toolkit, and we will be adding more information and tools on a regular basis.

Our latest update was made in July 2019, and inludes an expanded FAQ, a set of PowerPoint slides for members to use when presenting to colleagues and downloadable infographics from the reference guide and other sources document. 

If you have a suggestion for what we could include to help you promote environmentally sustainable diets, get in touch: 

Why do Environmentally Sustainable Diets matter?

Up to 30% of GHG emmissions globally are linked to agriculture and food production, and the environmental impact of the food we eat is one of the key changes we can make to tackle the issue of climate change. The BDA believes dietitians should be able to reconcile the nutritional and environmental science to give consistent messages about a healthy, sustainable and varied diet. They should be aware of the challenges that may result for vulnerable groups and individuals (e.g. those suffering ill health, pregnant women, people on low incomes, and older adults) and be able to provide advice on sustainable eating as appropriate.
