Nine months into his tenure as Secretary of Health and Human Services (HHS), Robert F. Kennedy Jr. has galvanized national attention around the “Make America Healthy Again” (MAHA) mission.
But experts remain divided over the specific approaches taken by RFK Jr. and whether they will achieve the goals he desires.
There is consensus around one of the key goals of the campaign but much division about whether RFK Jr. can deliver.
“Secretary Kennedy’s focus on chronic disease has been a rare and welcomed window for bipartisan consensus and has the potential to result in meaningful policy change,” Ada Peters and Richard Hughes IV wrote in Health Affairs Forefront.
But getting the policies right to deliver the solutions is where the bipartisan agreement dissipates.
“Secretary Kennedy has correctly identified chronic disease as a major driver of poor health and high healthcare costs,” said Dr. Richard Besser, president and CEO of the Robert Wood Johnson Foundation and a former director of the Centers for Disease Control and Prevention told PBS Newshour.
“But neither his record as health secretary nor most of the policies outlined … inspire confidence that he is the right person to solve this problem,” he added.
The HHS strategy report, the second installment of the MAHA initiative, amplified calls to address long-standing environmental and behavioral practices that harm children.
The central question facing Secretary Kennedy’s food and nutrition agenda is whether his path represents sustainable, evidence-based reform or merely high-profile political rhetoric. The consensus among public health experts suggests the MAHA movement offers tangible, positive reforms in chemical safety, but risks squandering those gains through scientific inconsistency and structural policy incoherence.
In the realm of food safety, Kennedy has delivered on promises to address specific chemical risks. One of the most visible successes has been the national initiative to phase out petroleum-based food dyes (certified color additives). The administration, citing concerns that these dyes offer no nutritional benefit and are linked to childhood conditions like ADHD, announced plans to eliminate six remaining certified colors, including Red No. 40 and Yellow No. 5, by the end of 2027.
This move builds on the earlier revocation of authorization for FD&C Red No. 3, which was banned from food after studies showed it caused cancer in male rats.
Major corporations, including General Mills, Kellanova, and Walmart, have already pledged to remove these dyes from their U.S. food portfolios, particularly for products sold to K-12 schools.
But while there are few defenders of excessive food dyes, some experts question whether their removal will be a game-changer.
“Taking petroleum-based food dyes out of our food supply certainly can’t hurt and may have some health benefits, but it is unlikely to appreciably reduce the burden of chronic disease in the United States,” said Professor Emily Barrett of Rutgers University.
A second critical move is the overhaul of the “Generally Recognized as Safe” (GRAS) pathway. Experts note that the current system includes a “self-affirmation” loophole, allowing companies to introduce new ingredients without notifying the FDA. Kennedy has directed the FDA to eliminate this self-affirmation pathway, requiring mandatory filing of GRAS notices for human and animal food uses.
While this is considered a “logical starting point” to restore regulatory oversight, experts caution that requiring FDA review for all new GRAS substances will demand significant new FDA resources, risking regulatory “bottlenecks” if the agency is underfunded.
While eliminating unnecessary food additives is widely praised, the MAHA approach to core nutritional guidance faces severe scientific backlash. The forthcoming Dietary Guidelines for Americans (DGA) is expected to be drastically simplified—potentially reduced from over 160 pages to just four—focusing heavily on “whole foods” and a strong critique of “ultra-processed foods” (UPF).
However, critics warn that this simplification risks sacrificing scientific rigor, as the DGA is traditionally a detailed policy document used to inform federal programs like SNAP and the school lunch program.
More controversially, Secretary Kennedy is expected to push for a re-evaluation of saturated fats, encouraging more foods like butter, cheese, and whole milk. This shift directly challenges the decades-long scientific consensus, reaffirmed by the 2025 Dietary Guidelines Advisory Committee, which recommends limiting saturated fat intake to less than 10% of total energy due to its link with elevated bad cholesterol and increased cardiovascular disease risk.
Experts contend that this policy pivot is based on “thin scientific evidence” and risks trading one metabolic risk (from refined carbohydrates and UPFs) for another equally serious risk: increased cardiovascular disease.
Health and environmental experts worry there a danger of a disconnect between the stated goals and the simultaneous actions to unravel research and regulations.
For instance, the administration has proposed slashing federal funding for the National Institutes of Health (NIH), which would undermine investigating chronic disease causes.
Furthermore, the MAHA strategy is criticized for fighting a selective war on toxins. While targeting high-visibility food additives, the administration is simultaneously being criticized for pushing to weaken environmental regulations on contaminants like PFAS and air pollutants, which are also strongly linked to chronic disease.
This selectivity creates an alarming trade-off: cleaning up food ingredients while allowing rising exposure to pervasive environmental toxins.
The food agenda is also complicated by the campaign against existing public health measures, such as the renewed campaign against fluoride in drinking water, which public health experts have long celebrated as a major innovation in cavity prevention.
Whether Secretary Kennedy and his team can deliver concrete steps with scientific support over the next 12 months will determine whether the MAHA food revolution is remembered more as powerful political noise or as a comprehensive pathway for lasting national health reform.
