Finally, it is foreseen that prepackaged products bearing one or more warning labels or precautionary label for sweeteners cannot (a) include on the label children’s characters, animations, cartoons, celebrities, athletes or mascots, interactive elements, such as visual-spatial games or digital downloads, which, aimed at children, incite, promote or encourage the consumption, purchase or choice of products with excess critical nutrients or with sweeteners, and (b) make reference on the label to elements outside the label for the same purposes as in the previous paragraph (Article 4.1.5).
