U.S. Health and Human Services Secretary Robert F. Kennedy Jr. ignited controversy this week during a bill signing in Texas, where he linked America’s health issues to what he described as “mitochondrial challenges” among children.
Kennedy attended the ceremony as Texas Gov. Greg Abbott and Republican lawmakers enacted several measures modeled on his “Make America Healthy Again” agenda. The new laws revise state nutrition and fitness standards, tighten food quality requirements, and ban food stamp recipients from purchasing soda and sweets.
As he addressed the audience, Kennedy suggested the country’s health problems were visibly affecting children. “I’m looking at kids as I walk through the airport, or as I walk down the street,” Kennedy said. “They are overburdened with mitochondrial challenges.
You can tell from their faces and by their body movements, and their lack of social connection.” The unusual phrasing quickly drew widespread criticism online. Commentators across social media ridiculed the health secretary’s remarks, questioning both the science and the appropriateness of diagnosing children in public spaces.
“I, too, am overburdened with mitochondrial challenges,” Irish sociologist Kieran Healy wrote on Bluesky. “I can’t imagine why kids are repelled by the leathery guy who looks them up and down in airports for ‘mitochondrial challenges,'” journalist Mike Rothschild posted on X.
“He’s diagnosing children from 30 yards away with fake diseases,” wrote military veteran John Jackson on X. Other critics noted the strangeness of the terminology itself. “Horrors abound, but a guy who will say ‘overburdened with mitochondrial challenges’ and somehow be in charge of the nation’s public health infrastructure is TOUGH TO BEAT,” journalist Dave Levitan quipped on Bluesky.
Medical experts also weighed in, highlighting the scientific inaccuracy of Kennedy’s language. “Serious question: What do the cuckoos mean by ‘mitochondrial challenges?'” Dr. Melissa Johnson posted on Bluesky. “I’m deeply fascinated by whatever crunchy-granola clean-eating overnight oats conspiracy theory is operating here.”
“‘Mitochondrial challenges usually mean you’re dead,” Dr. Tessa Fisher wrote on Bluesky. “Best case, you have severe exercise intolerance.” Kennedy, a longtime critic of vaccines and pharmaceutical practices, has frequently drawn fire for statements that depart from scientific consensus.
His latest comments added fuel to ongoing debates over his leadership of the nation’s health agencies, especially as critics accuse him of politicizing public health while promoting questionable science. For now, the new Texas laws remain in place, but Kennedy’s remarks continue to echo across the internet, sparking both disbelief and satire.
