Study: Octagonal Warning Labels Most Effective for Jamaican Consumers

According to a recently published study, the Octagonal Warning Label System for food and drink products is the most effective to help Jamaican consumers to make healthier choices.

The study is titled: “Effects on front-of-package nutrition labelling systems on understanding and purchase intention in Jamaica: Results from a multiarm randomized controlled trial”. The study showed that these labels assisted Jamaicans best in correctly identifying the least harmful option and the presence of excessive amounts of critical nutrients. Using this system, participants also performed best in choosing the least harmful product more often. A randomized control trial is the gold standard to measure effectiveness.
