New analysis of 118 studies conducted over 30 years could help refine, improve food labelling policies — ScienceDaily
A new analysis has integrated findings from 134 studies of the impact of color-coded nutrition labels and warnings found on the front of some food packaging, indicating that these labels do indeed appear to encourage more healthful purchases. Jing Song of Queen Mary University of London, UK, and colleagues present these findings in the open-access journal PLOS Medicine.
Some countries have introduced mandatory front-of-package labeling in hope of improving people’s diets and reducing the burden of diseases associated with poor diets. These labels may employ color coding to indicate nutrition, or they may warn consumers about unhealthful features of products.
