Health Secretary Robert F. Kennedy Jr. has made it his Make America Healthy Again mission to challenge the medical establishment. President Donald Trump's signature law, the One Big Beautiful Bill Act, could entrench it. Kennedy sees America's medical schools as bastions of groupthink that ignore the root causes of disease. But newly proposed caps on student loans that stem from the law would favor establishment institutions over nontraditional schools aligned with Kennedy's view that Americans are sicker than ever because of what they eat, the chemicals they're exposed to, and how little exercise they get.
