Robert F. Kennedy Jr., the U.S. Health Secretary, is once again in the spotlight for controversial claims linking common painkillers like Tylenol to autism. During a recent Cabinet meeting with President Donald Trump, Kennedy revived his long-debated theory that taking painkillers during pregnancy may increase the risk of autism in children. Despite admitting no scientific proof yet exists, he is pushing forward with research to prove the connection.
Kennedy also made a startling claim, suggesting boys circumcised as infants have double the autism rates because they are given Tylenol afterward. This assertion refers to older studies reporting a correlation but not causation. Experts in the medical community and organizations like the National Autistic Society have denounced these claims as unfounded, dangerous, and irresponsible. They stress that no credible evidence connects painkillers or circumcision to autism.
RFK Jr: There are two studies that show children who are circumcised early have double the rate of autism. It's highly likely because they were given Tylenol."

His comments have drawn sharp criticism for promoting misinformation, especially given his influential position, where unsubstantiated statements could harm public health efforts. The debate around Kennedy’s views highlights the ongoing tension between scientific consensus and fringe theories promoted by prominent figures.
