Displacing Empty Calories with Nutrient Dense Food: How can UK farmers be rewarded for practices that promote nutrient density?

The UK faces a growing health crisis, with rising rates of chronic diseases putting immense pressure both on individuals and the NHS. While the link between food and health is now well-established, emerging evidence suggests that the way food is produced could also play a critical role in combating our health issues. Farmers could be key to improving public health by enhancing the nutritional quality of their produce.

The idea that "food is medicine" dates back to Hippocrates, but modern research is revisiting this concept with a new focus: not just on what we eat, but how our food is produced. Concerns are mounting that the nutrient density of our food is in decline. This has sparked interest in whether changes in agricultural methods could lead to more nutritious food, thereby helping to prevent chronic diseases and promote good health.

A small but growing number of researchers and farmers are exploring how specific farming methods could boost the nutritional content of food. If successful, these methods could be integrated into broader strategies to improve public health. Through my study tour, I identified four key areas where evidence demonstrates a clear link between farming method and nutrient density:

1. Soil Health: Regenerative farming practices that improve soil health can increase the populations of beneficial microorganisms, which play a crucial role in nutrient cycling. Healthier soils could therefore lead to more nutrient-rich crops.
2. Breeding and Variety Selection: Selecting and breeding crop varieties with a greater ability to take up nutrients could help to improve nutrient density.
3. Biofortification: Enhancing the nutrient content of crops either through selective breeding to take up a particular nutrient, or by applying nutrients directly to plants during growth, potentially leading to foods that are richer in minerals.
4. Animal Feed: Influencing the nutritional content of animal products; meat, milk and eggs, through optimising the animal’s diet.

While the potential benefits of these methods are promising, there is still much work to be done. Collaboration between researchers and farmers is essential to understand the impact of different farming practices on food quality. Large-scale human health trials may also be needed to confirm the health benefits of consuming more nutrient dense foods. Additionally, healthcare professionals must become more aware of how food quality, influenced by farming methods, can affect health.

For real change to occur, comprehensive data collection and stronger evidence are necessary, along with closer collaboration between agricultural and public health sectors. Farmers who sell directly to consumers have an opportunity to promote the nutritional benefits of their practices, however broader adoption will require systemic changes, including potential new incentives that reward farmers for not just the quantity, but the quality of food they produce. If these efforts are successful, they could lead to a new understanding of the role of food production in public health and potentially reduce the burden of chronic diseases. It could also transform how we value food in society.
