A study from the University of Oxford indicates that food and beverage manufacturers can significantly improve both nutritional quality and environmental sustainability by modifying just 10% of their product portfolios. Published in *Nature Food*, the research reveals that companies do not need to completely overhaul their offerings to meet health and environmental goals.

The study found that reformulating or substituting a small fraction of top-selling products can lead to substantial benefits in public health and reductions in carbon emissions. It assessed thousands of grocery items available in the United Kingdom and concluded that targeted changes can have a considerable impact without necessitating extensive changes to manufacturing operations.
Major manufacturers, especially those with extensive private-label products, have the most flexibility to optimize their offerings. In contrast, companies focused exclusively on specialized goods may have fewer options. The research highlights that substituting high-carbon or nutrient-poor ingredients with more beneficial options can enhance product health ratings while maintaining consumer appeal.
Regarding sustainability, the 10% reformulation threshold provides a practical approach for manufacturers to comply with increasingly stringent reporting requirements, such as the European Union’s Corporate Sustainability Reporting Directive (CSRD). With a significant portion of greenhouse gas emissions stemming from agricultural ingredients, altering a few high-volume products can greatly mitigate their environmental impact.
Dr. Michael Clark, the lead author and associate professor at Oxford, explained that this research enables companies and governments to simultaneously assess nutritional profiles and environmental factors, thus steering clear of conflicts between health aims and climate initiatives.
The findings have important implications for dairy manufacturers, which are crucial in retail and branded portfolios. Although dairy products face scrutiny for their environmental footprint, they remain valuable sources of nutrients. By adjusting formulations—such as reducing sugars in products like flavored yogurts or sodium in processed cheeses—dairy producers can enhance their market position.
Additionally, aligning manufacturing processes with sustainable practices at the farm level can reinforce market competitiveness. Food companies targeting specific product improvements can influence agricultural practices among suppliers, encouraging carbon reduction methods that allow producers to secure favorable contracts. As food manufacturers strive to meet consumer demand and regulatory pressures, integrating sustainability into product development will be essential for maintaining the viability of the dairy industry moving forward.
