Sustainable food choices are essential in our efforts to meet the United Nations' Sustainable Development Goals (SDGs), offering a pathway to a healthier planet and society. These choices encompass a range of practices and decisions that, when implemented collectively, can have a profound impact on global sustainability.
One of the most direct impacts of sustainable food choices is their alignment with SDG 2: Zero Hunger. By advocating for diversified diets and resilient food systems, sustainable choices enhance food security and ensure that all people have access to nutritious food. This is especially important in regions where food scarcity and malnutrition are prevalent. Emphasizing local and seasonal foods, as well as supporting small-scale farmers and sustainable agriculture practices, contributes to a more equitable and robust food system.
SDG 12: Responsible Consumption and Production is another key area where sustainable food choices make a significant impact. This involves not only what we eat but also how our food is produced, processed, and distributed. By choosing foods that are produced with minimal environmental impact, consumers can drive demand for more sustainable production practices. This includes reducing the reliance on harmful chemicals and pesticides, conserving water, and promoting biodiversity. Additionally, responsible consumption involves reducing food waste at every stage, from production to consumption, which is critical in minimizing the environmental footprint of our food systems.
In terms of climate action (SDG 13), sustainable food choices play a pivotal role. The food sector is a major contributor to greenhouse gas emissions, primarily from livestock production, deforestation for agricultural expansion, and food waste. By opting for plant-based diets and reducing the consumption of meat and dairy products, individuals can significantly lower their carbon footprint. Furthermore, reducing food waste not only lessens the amount of food that ends up in landfills, where it produces methane, a potent greenhouse gas, but also conserves the resources used in food production.
SDG 3: Good Health and Well-being is closely linked to our dietary choices. A diet rich in fruits, vegetables, whole grains, and lean proteins is beneficial for health and can prevent a range of chronic diseases, such as heart disease, diabetes, and certain cancers. Sustainable food choices often emphasize whole, minimally processed foods, which are integral to a healthy diet.
Lastly, sustainable food choices have implications for life below water (SDG 14) and life on land (SDG 15). By reducing the demand for overexploited fish species and choosing sustainably sourced seafood, we can help protect marine ecosystems. Similarly, choosing foods that do not contribute to deforestation, such as responsibly sourced palm oil, helps to preserve forests and the biodiversity they support.
Making sustainable food choices is a multifaceted approach to addressing some of the most pressing challenges of our time, including hunger, health, environmental degradation, and climate change. By aligning our food choices with these goals, we can contribute to a more sustainable and equitable world.
In view of all kinds of sustainability concerns related to our current diet, it is essential to gain a good understanding of the sustainability motives consumers have for selecting their food. A comprehensive and validated scale to measure sustainability motives within the full range of food choice motives could contribute to this understanding, especially as sustainability is a multi-faceted concept in which the different aspects can sometimes be conflicting.

Western diets are characterised by a high intake of meat, dairy products and eggs, causing an intake of saturated fat and red meat in quantities that exceed dietary recommendations. The associated livestock production requires large areas of land and lead to high nitrogen and greenhouse gas emission levels. Although several studies have examined the potential impact of dietary changes on greenhouse gas emissions and land use, those on health, the agricultural system and other environmental aspects (such as nitrogen emissions) have only been studied to a limited extent.
