Nutrition Professionals as Environmental Stewards and Climate Champions (2022 Mar)

“The intersection of the food system, the environment and human health is nothing short of complex, but as experts in the food and nutrition space, we have an incredible opportunity (and obligation) to be trailblazers in the fight around climate change.  

No matter what sector of the nutrition field we work in, we can exert our influence in many areas, from individual and institutional food consumption to national level food policy. Whether we work with what’s being eaten, how it’s being grown or how it’s being disposed of, we can make a difference.  If you write, speak publicly or have an online platform, you can use it to educate on and promote these ideas and to make plant based food look as delicious as humanly possible.  If you are in academia, you can incorporate issues of sustainability and regenerative agriculture into any and all aspects of your curriculum.  

Again, as systems thinkers and those with a vested interest in human wellness, we cannot separate a healthy foods system from a healthy biological or eco-system. The good news is that the foods that are healthy for humans are usually those that have a lighter environmental footprint [17].  It appears that once again, food is not only medicine for the person, but for the planet and nutrition professionals are leading the charge.”
