Fitness icon Jillian Michaels has joined Robert F. Kennedy Jr. in a controversial push to investigate environmental factors behind autism, adding celebrity weight to a debate that continues to divide scientists, policymakers, and advocates.
At a Glance
- Jillian Michaels endorses RFK Jr.’s call for environmental autism research
- Kennedy, as HHS Secretary, calls rising autism rates a national “epidemic”
- CDC data shows autism in U.S. children increased to 1 in 31 by 2022
- Critics accuse Kennedy of fueling stigma and misinformation
- HHS to launch new studies exploring possible environmental triggers
Environmental Focus Over Genetics
In a recent interview with Newsmax, Michaels echoed Kennedy’s claim that genetic predisposition alone does not explain the sharp increase in autism diagnoses. “There is no way better awareness can account for a 300% increase in 20 years,” Kennedy said, calling for deeper investigation into pollutants, toxins, and industrial exposures. Michaels agreed, arguing that identifying preventable environmental triggers could help protect future generations.
Kennedy’s shift away from vaccine skepticism has done little to quiet critics, but his new role as Health and Human Services Secretary gives him the authority to refocus federal research dollars. He claims that the government has long overfunded genetic studies while neglecting environmental inquiries. “The amount of money and resources put into studying genetic causes… has been 10 to 20 times what’s been spent to study environmental factors,” he told WRKF.

A Growing Divide
The CDC reported that autism affected 1 in 36 U.S. children in 2020—rising to 1 in 31 by 2022—statistics Kennedy cites as proof of an escalating health crisis. However, many researchers argue this increase is largely due to broader screening criteria and increased public awareness. According to Rutgers researcher Walter Zahorodny, “[B]etter awareness cannot be driving a disability like autism to increase by 300% in 20 years,” as cited by WRKF.
Advocacy organizations have responded cautiously. While some welcome more research into overlooked causes, others warn that focusing solely on causation rather than services can undermine support for autistic individuals and families. Critics also worry that Kennedy’s past rhetoric—particularly around vaccines—continues to cast a long shadow over his public health credibility.
New Research Ahead
Despite the controversy, the Department of Health and Human Services has announced plans to conduct multiple studies aimed at identifying possible environmental contributors to autism. According to NewsNation Now, these may include factors such as maternal toxin exposure, chemical pollutants, and industrial byproducts.
The timeline for this research is uncertain, and experts warn that establishing clear causal links may be challenging. However, Kennedy and Michaels emphasize the need for the federal government to pursue this inquiry—not to assign blame, but to inform choices that protect future generations. Whether this will yield actionable results or reignite old debates is unclear. With Kennedy leading the initiative and celebrity support, the discussion around autism’s causes is once again prominent.
