Every movement has its messenger. For the Make America Healthy Again crowd, it’s Robert F. Kennedy Jr., and an endless stream of often-inaccurate, fear-driven content. For the people trying to push back? It might just be Jessica Knurick — a dietitian-turned-Instagram star who’s managed to turn evidence-based science into something that actually feels watchable.
In a recent conversation with Vox senior health correspondent Dylan Scott, Knurick talks about her approach: meet people where they are (scrolling their feeds), acknowledge that their concerns are real (America’s health systems are deeply broken), and then gently but firmly redirect the conversation toward what the data actually says.
It’s not just fact-checking for the algorithm era; it’s public health reframed as something human, playful, and, above all, trustworthy.
But underneath her TikToks and snappy charts lies a bigger question this story takes on: what happens when appeals to authority stop working altogether? When people tune out “experts,” where does science go to be heard? Knurick is trying one answer — using the same viral tools that have fueled the MAHA movement to carve out space for something sturdier than fear and suspicion.
