In an effort to tackle the increasing prevalence of obesity, the U.K. government has introduced a number of public health strategies over the years, including changes to how we label foods. For example, the "traffic light" color-coding system, which was introduced in 2013, aims to make it easier for consumers to know whether or not the foods they're eating are healthy for them.
But some critics feel that this kind of labeling may still be difficult for people to fully understand or practically apply, and may not necessarily lead to people choosing healthier food. Given obesity is still on the rise, it's clear current strategies aren't working.
