Adherence
Nutrient-based dietary guidelines (e.g., limiting fat or sugar) are less effective for public understanding and policy translation than food-based or processing-related terms (e.g., 'ultra-processed foods' or specific food examples).
When following dietary guidelines, look for recommendations that specify *which* foods to limit (like sugary drinks or ultra-processed snacks) rather than just abstract nutrients (like fat or sugar). This approach is easier to understand and less likely to be manipulated by food companies through reformulation. If a guideline uses nutrient-based terms, try to translate them into specific food choices you can identify on a label.
Previous studies have found that nutrient-based terms result in poorer, decontextualised comprehension of FBDG messages by the general public, compared with more tangible examples of real foods(15).
Why this rating
The paper is a systematic review of terminology in guidelines, citing observational studies and consumer comprehension surveys, but does not present new primary clinical trial data.
