Meet Jessica Knurick, The Dietitian Taking On The 'MAHA' Movement

Jessica Knurick is a registered dietitian with a PhD who has rapidly emerged as one of the most influential public health voices on social media. With more than 1.1 million followers on Instagram and over 335,000 on TikTok, she is using the same platforms that fueled misinformation to push back with evidence-based content. Her style is simple but powerful. She blends humor, accessible explanations, and scientific accuracy in short videos that debunk myths and highlight where health narratives go wrong.Her journey into this digital advocacy space was personal. During her first pregnancy in 2019, she noticed scattered but not overwhelming amounts of misleading information targeted at expecting mothers. By the time she had her second child in 2022, the pandemic had amplified conspiratorial and fear-based health content across platforms. What had once been background noise became the dominant message being shown to her feeds. That was when she realized the scale of the problem, and the urgent need for credible counter voices.Understanding the MAHA MovementThe Make America Healthy Again (MAHA) movement emerged out of a growing distrust in public health institutions. Initially fueled by wellness influencers and conspiracy-laced narratives about toxins, chemicals, and corrupt medical systems, the movement gained a national platform when Robert F. Kennedy Jr. launched his presidential campaign in 2024. Now serving as Secretary of Health and Human Services under Donald Trump, Kennedy and the MAHA agenda are reshaping health policy with their focus on distrust of regulation, vaccines, and science.MAHA thrives because it taps into genuine frustrations. Rising chronic disease rates, expensive healthcare, and a food system often criticized for prioritizing profits over people’s well-being all resonate with Americans. But where the movement gains attention is in its framing, blaming shadowy corruption, demonizing ingredients like seed oils or food dyes, and questioning the legitimacy of mainstream health guidelines.Read: What Is 'Make America Healthy Again' All About?The results have been concerning. Falling vaccination rates, for example, contributed to a historic measles outbreak this year. Yet millions of Americans continue to be swayed by MAHA’s polished social media messaging and distrust of traditional experts.Knurick’s Counter-Narrative StrategyKnurick does not deny that the US has a chronic disease crisis. She acknowledges that too many people are living with conditions linked to lifestyle and systemic problems. What she challenges is how MAHA leaders explain those problems and the solutions they propose.Her method is to meet people where they are, on Instagram and TikTok, and arm them with tools to navigate misinformation. In her videos, she often points out logical fallacies, like confusing correlation with causation. She also highlights overlooked factors that evidence shows drive chronic disease: income inequality, lack of access to healthcare, education gaps, and systemic disparities. These social determinants of health are almost entirely absent from MAHA’s messaging.Knurick also calls out contradictions and financial interests within the MAHA leadership. Many of its most prominent figures run supplement companies or wellness product businesses, financially benefiting from the fear they spread. She argues that if the pharmaceutical and food industries deserve scrutiny for conflicts of interest, so too should the wellness industry, which operates with far less regulation.Balancing Tone and ReachOne of Knurick’s challenges is tone. She knows that many MAHA supporters are parents, especially mothers, who are genuinely anxious about their children’s health. These women are vulnerable to fear-based messaging like “Are you poisoning your kids?” which thrives in wellness circles. Being a mother herself, Knurick understands the emotional triggers at play.Her approach is firm but not condescending. She avoids personal attacks on ordinary supporters, focusing instead on the misinformation itself. While her critiques of Kennedy are sharp, she maintains that her goal is not to mock but to explain. The result has been encouraging. Many followers who initially came to her page as skeptics admit to being swayed by her evidence-backed explanations.Also Read: Trump’s Surgeon General Pick Raises Eyebrows With Vaccine Comments And Wellness ClaimsStill, she recognizes she will not reach everyone. Those deeply loyal to MAHA leadership may tune out. But Knurick’s growing following and steady stream of messages from people who have reconsidered their views suggest her efforts are making a difference.Rebuilding Trust in ScienceKnurick’s larger mission goes beyond countering individual claims. She is working to rebuild a culture of trust in evidence and science. In a world where traditional appeals to authority no longer carry weight, she believes teaching media literacy is essential. By showing people how to spot out-of-context data, manipulated graphs, or exaggerated claims, she hopes to empower her audience to become more discerning consumers of information.Her efforts are not just about defending institutions but about reframing public health in a way that resonates. She agrees with MAHA that the system often fails people. Where she differs is in how to fix it. Instead of scapegoating food dyes or dismissing vaccines, she emphasizes systemic reforms, improved access, and real policy solutions.Why Knurick Matters NowThe battle over health information is no longer confined to medical journals or government press releases. It is happening on TikTok, Instagram, and in the hands of influencers. By stepping into that arena, Knurick represents a new model for public health communication: expert-led, evidence-driven, but adapted to the realities of the digital age.As misinformation continues to spread and movements like MAHA reshape national policy, her work is more critical than ever. She is not just correcting false claims but also offering a vision of what a more honest, evidence-based conversation about health could look like.
