Changes in food purchases after the Chilean policies on food labelling, marketing, and sales in schools: a before and after study

Abstract

<p class="first" id="d1103395e121">In 2016, Chile implemented a unique law mandating front-of-package warning labels, restricting marketing, and banning school sales for products high in calories, sodium, sugar, or saturated fat. We aimed to examine changes in the calorie, sugar, sodium, and saturated fat content of food and beverage purchases after the first phase of implementation of this law. </p>
