We welcome your involvement to help promote uptake and use of the Global Diet Quality Score (GDQS) metric and app through your engagement with this Social Media Toolkit. The Toolkit provides a variety of customizable graphics, hashtags, and messages that can be shared on social media platforms, such as Twitter and Facebook, to help raise awareness about the importance of diet quality, the need to collect data on what people are eating, and how GDQS data can be used to inform programs and policies designed to improve diet quality. Advocates and users of the GDQS metric and the GDQS app are invited to use and adapt messages from the GDQS Social Media Toolkit to further encourage collection and use of diet quality data.
