(As Robert F. Kennedy Jr. pushes to eliminate artificial food dyes, consumers are left with an important question: Does changing an ingredient list actually make food healthier?)
Walk through almost any grocery store, and you’ll find products advertising natural ingredients, artificial dye-free recipes, and cleaner labels. These promises sound reassuring, particularly to parents concerned about what their children eat. But the phrase “chemical-free food” is scientifically misleading. Water, vitamins, proteins, and even the ingredients in a freshly picked apple are chemicals. What matters is not whether a substance has a complicated name or comes from a laboratory, but whether it poses a meaningful risk at the amount consumed. Removing an ingredient can improve a product, but only when the change addresses a genuine problem.
U.S. Health and Human Services Secretary Robert F. Kennedy Jr. has made eliminating petroleum-based synthetic food dyes a prominent part of his food-policy agenda. In April 2025, the Department of Health and Human Services and the Food and Drug Administration announced an initiative to phase out these dyes, largely through cooperation with manufacturers. The effort gained industry commitments to reformulate products, and in February 2026 the FDA made it easier for qualifying products to advertise that they contain no artificial colors. Kennedy has argued that these dyes provide no nutritional benefit and pose health risks, particularly to children. However, a voluntary reformulation initiative and a change in labeling policy are not, by themselves, proof that every affected product will become healthier.
That does not mean concerns about artificial dyes are imaginary. A 2021 scientific assessment by California’s Office of Environmental Health Hazard Assessment concluded that synthetic food dyes can contribute to hyperactivity and other behavioral effects in some children, although individual sensitivity varies. Separately, the FDA revoked authorization for Red No. 3 after studies found cancer in male laboratory rats exposed to high doses. The agency emphasized that this finding involved a mechanism specific to those rats and that available evidence does not show Red No. 3 causes cancer in humans. These distinctions matter. There are legitimate reasons to examine particular additives carefully, but different dyes, health effects, and levels of exposure should not be treated as interchangeable.
Another issue is what manufacturers put into food after removing an ingredient. A brightly colored snack made with plant-derived coloring may appeal to consumers who wish to avoid synthetic dyes. Yet if it still contains substantial added sugar, sodium, or saturated fat, changing its color source does not necessarily improve its nutritional profile. Natural ingredients are not automatically safer, either. The FDA requires both synthetic and naturally derived color additives to meet safety standards for their intended uses. A responsible reformulation should be evaluated by what actually changes in the finished product, rather than by whether its packaging uses the word “natural.”
It is also important not to confuse food coloring with every other type of additive. Some ingredients help preserve food, reduce spoilage, maintain texture, or restore nutrients lost during processing. Preservatives, for example, can help limit the growth of microorganisms that cause foodborne illness. Removing such ingredients without suitable replacements could create problems rather than solve them. This is where broad promises to remove “chemicals” become especially unhelpful: they encourage consumers to view a vast range of substances as one category, even though those substances serve different purposes and have different safety profiles.
Kennedy’s campaign has brought renewed attention to what goes into America’s food supply, and scrutiny of unnecessary additives can be worthwhile. But the real measure of success should be evidence of improved health and safety—not the number of unfamiliar words removed from a label. Consumers deserve transparent ingredient information, sound scientific testing, and honest explanations of both benefits and risks. A candy without synthetic coloring is still candy. Removing a questionable dye may be a meaningful change, but making food genuinely healthier requires looking beyond its color.
