Many adults in the United Kingdom say they want to reduce their intake of ultra-processed foods, but a recent study published in BMC Global and Public Health on Apr. 19 finds that confusion about what qualifies as an ultra-processed food remains a significant barrier.
The issue matters because ultra-processed foods now account for more than half of the average daily energy intake in the UK, and research has linked high consumption of these foods to an increased risk of non-communicable diseases. Despite ongoing public health campaigns, most people still struggle to apply scientific definitions like the Nova classification system when making food choices.
Researchers interviewed 30 UK adults who were primarily responsible for household food decisions between July and October 2024. The study found that while participants generally viewed ultra-processed foods as artificial or unhealthy, few could accurately distinguish them from other processed items using current scientific frameworks. For example, obvious examples such as crisps and soda were easily recognized as highly processed, but there was confusion around products like yogurt or plant-based meat alternatives.
The study also highlighted that while many participants distrusted industry-sponsored information about nutrition, some relied on social media influencers for advice. Even those with negative views about ultra-processed foods often continued buying them due to cost, convenience, taste preferences, or family habits. The authors said that "consumer awareness alone is unlikely to produce meaningful change" if healthier options remain less affordable or accessible.
According to summary statistics from the participant group, most were women aged between 20 and 72 years old with higher educational backgrounds. However, researchers noted limitations in their sample due to underrepresentation of people with lower education levels and those from Black communities.
The findings suggest that while education is important, broader policy changes may be necessary to help reduce national consumption of ultra-processed foods. The authors concluded that future research should include more diverse groups so policymakers can develop effective communication tools and strategies.
