Robert F. Kennedy Jr., now serving as the US Health Secretary, has made tackling America’s chronic disease crisis his central mission. He argues that 60% of Americans suffer from conditions like obesity, diabetes, and heart disease—what he calls an “epidemic of chronic illness.” His stark diagnosis is shared by many health experts, but his controversial record and radical reforms are deeply divisive.Kennedy has long promoted unfounded health conspiracies, including theories about Covid-19 and chemicals in water. Since taking office, he’s slashed thousands of jobs at the Department of Health and Human Services and eliminated entire CDC programs. Marion Nestle, a retired NYU professor, praised his focus on chronic disease but warned that gutting the public health infrastructure undermines his goals.Kennedy has targeted multinational food companies, claiming they expose children to harmful additives banned elsewhere. His first major move: phasing out petroleum-based food dyes like Red No. 40 by 2026. Food blogger Vani Hari, a prominent supporter of Kennedy’s “Make America Healthy Again” (MAHA) movement, believes pressure on companies is already forcing change. PepsiCo, for example, pledged to remove artificial colors from its snacks by year’s end.A bill Kennedy backs in Texas could require labels warning if products contain additives banned in Australia, Canada, the EU, or the UK. But the Consumer Brands Association says US food ingredients are safe and well-regulated.Some experts argue Kennedy’s focus on additives ignores structural issues like poverty and aggressive junk food marketing. “Individual actions are a drop in the ocean,” says Yale epidemiologist Nicola Hawley, who worries Kennedy is drifting into misinformation about environmental risks and chronic disease.Kennedy is updating national dietary guidelines to reduce added sugars and promote whole foods, and has called for bans on using food stamps for junk food. He also supports efforts to remove fluoride from drinking water, labeling it a “dangerous neurotoxin,” despite scientific consensus that it’s safe at standard levels.Kennedy’s views on vaccines remain the most controversial. While he insists he’s not “anti-vax,” he has a long history of vaccine skepticism. He previously ran Children’s Health Defense, a group that questioned vaccine safety, and praised Andrew Wakefield, the discredited doctor behind the false MMR-autism link. Though Kennedy says he won’t restrict vaccines, he describes immunization as a “personal choice” and emphasizes alternatives like vitamin supplements.Kennedy fired all 17 members of the CDC’s vaccine advisory committee, claiming conflicts of interest, and replaced them with a smaller, administration-picked panel. Critics like Dr. Amesh Adalja of Johns Hopkins worry this will erode trust in childhood vaccination programs.The new panel’s first move was to stop recommending flu vaccines containing thimerosal, a preservative Kennedy has long opposed. Meanwhile, the CDC, under Kennedy’s direction, announced a new study on potential links between vaccines and autism—despite decades of research finding no credible connection. Autism researcher Eric Fombonne called the effort “nonsensical,” warning it promotes harmful stigma.Kennedy’s comments that autistic children will “never pay taxes, hold a job, or go on a date” angered many in the autism community, who see his statements as perpetuating fear and stereotypes. Yet some parents of children with profound autism said his remarks reflect their reality.Kennedy promises a report on autism’s causes by March 2026, but many experts fear he’s ignoring well-established genetic factors in favor of unproven environmental theories.Kennedy’s background as an environmental lawyer shapes his combative approach toward big business, food companies, and the pharmaceutical industry. Supporters like Tony Lyons, who co-founded a pro-Kennedy political committee, see him as a corruption fighter determined to challenge vested interests. Critics worry his biases lead him to predetermined conclusions unsupported by evidence.“America finally has a chance to prioritize chronic disease,” says Harvard nutrition professor Jerold Mande. “But the answers must come from science, not ideology. The jury is still out on whether Kennedy will deliver.”
