Sustainable Diets

Our food choices can make a positive difference to people and nature – improving our own health, the health of others, and the health of the planet.

Over-dependence on select foods, a lack of diversity in our diets and the continued consupmtion of unsustainably produced items have a harmful impact on nature. And while billions of people face an obesity crisis, billions of others struggle to get what they need.

If we all followed the dietary guidelines recommended by experts at the United Nations, then there’d be enough of the right food for all of us – and more space for nature to thrive.

The true impact of what we eat

Almost every country in the world faces a serious challenge due to our eating habits. Whether the challenge is undernutrition or obesity, global development efforts in areas such as poverty and disease are under threat.

Our diets also threaten the climate, life on land and life below water. The unsustainably increasing appetite for red meat and dairy leads to more carbon release, both from animal emissions and clearing land for ranching and growing feed. Overfishing has led to a drastic reduction in 93% of all fish in the ocean. Processed food requires more energy to produce and food-miles to distribute than freshly farmed produce.

People need to understand the true impact on nature of what they choose to eat – and that eating seasonal, local and sustainable produce can greatly benefit everyone.

What we’re doing
We are working towards a future where everyone has access to the right amount of nutritious food. Our ambition is to make sure at least half of the world follows United Nations dietary guidelines within the next decade.

We conduct research and develop guides to help consumers understand how they can eat more healthily and with a lower impact on nature and climate. We partner with chefs to create recipes and promote the consumption of sustainable foods, and work with innovative producers who are exploring new ways of farming and producing nutritious food.

Get involved


  • Check your national dietary guidelines and do your best to follow them
  • Avoid processed food and eat lots of fresh fruit and vegetables
  • Eat local, seasonal and sustainably-sourced food
  • Don’t eat too much red meat – and when you do, look for meat which has been sustainably produced
  • Don’t eat types of fish which are over-harvested – shellfish and molluscs are great alternatives


If we don’t change the way we eat food, the future of our planet will continue to be at risk. Please share this with your friends and communities.
