Much has been written about the benefits—and challenges—of social media platforms in communicating health and nutrition science to the public. It has generally been assumed that cyber platforms such as Facebook, Twitter, Instagram, SnapChat, and similar businesses function, in effect, like communication tools, albeit with some susceptibility to misinformation and disinformation. Less attention has been paid to the power of the downside of these new communication tools, which may be far more vulnerable to misinformation and disinformation than previously believed. More strenuous communication strategies may need to be deployed in the ongoing effort to deliver credible and reliable health and nutrition information to consumers. The authors here explore the significant challenges posed, going forward, to health and nutrition communications, offering an enhanced response.
