As temperatures rise and consumers turn to frozen treats, concerns over the safety of certain additives in ice cream are prompting new scrutiny from health officials and food scientists alike. A growing body of research is linking widely used emulsifiers—chemical agents that enhance texture and shelf life in processed foods—to possible long-term health effects, particularly in the gut.
One such emulsifier, polysorbate 80, has drawn attention for its role in making ice cream slow to melt—a feature hailed by food manufacturers but now under scientific review. A viral demonstration by a food additive supplier showed scoops of ice cream maintaining their form under heat, thanks to the additive. Polysorbate 80 is just one of several emulsifiers, including carboxymethyl cellulose, carrageenan, and maltodextrin, under investigation for potentially altering the gut microbiome, damaging gastrointestinal linings, and contributing to chronic inflammation.
These additives are found in a wide array of ultraprocessed foods, including many brands commonly featured in ice cream franchise outlets and large-scale dessert manufacturers. While these substances have long been deemed safe under the FDA’s “generally recognized as safe” (GRAS) designation, new research challenges their presumed safety—especially in light of their impact on human gut health.
Benoit Chassaing, research director at France’s National Institute of Health and Medical Research, emphasized the potential harm of these compounds. “There is a lot of data showing these emulsifiers are detrimental to the microbiota,” he said, noting the urgent need for human clinical trials. Early studies, many conducted on mice or in lab simulations of the human gut, suggest links between emulsifiers and inflammatory bowel diseases, metabolic disorders, and even cancer.
The issue is now on the radar of U.S. regulators. Health and Human Services Secretary Robert F. Kennedy Jr. has prioritized food safety under his “Make America Healthy Again” initiative. A recent draft report by the department listed emulsifiers among the food additives warranting deeper review, though officials admitted that more comprehensive data is needed.
Newly appointed FDA Commissioner Martin Makary echoed the concerns during his Senate confirmation hearing, stressing the need to examine ingredients affecting the gut microbiome. “These chemicals are creating an inflammatory response in the gastrointestinal tract,” he testified.
The concern is not merely academic. Consumers with digestive disorders, like Lewis Rands of Australia, report real-world benefits from avoiding emulsifiers. Rands, a genetic scientist who suffers from severe inflammatory bowel disease, found relief by removing processed additives from his diet—replacing brands like Ben & Jerry’s with Häagen-Dazs, which prominently markets products free from emulsifiers and stabilizers.
While Häagen-Dazs promotes a “no additives” message—“No emulsifiers. No stabilizers.”—its parent company, Dreyer’s Grand Ice Cream, also sells other brands such as Drumstick and Edy’s, which contain these additives. Meanwhile, Ben & Jerry’s has not publicly responded to questions about its use of emulsifiers.
This debate also intersects with business decisions in the frozen dessert industry. As more consumers seek cleaner labels, opportunities may emerge for health-conscious entrepreneurs exploring latest ice cream franchise trends and yogurt franchise opportunities. Brands that eliminate or limit chemical additives could have a competitive edge as public awareness grows and regulatory pressure intensifies.
Despite mounting evidence, some researchers caution against premature conclusions. “It’s important not to overinterpret results,” said Peter Gibson, a gastroenterology professor at Monash University, whose recent study found no significant impact of emulsifiers on Crohn’s disease in a short-term trial. Gibson and other scientists argue that larger, long-term human studies are necessary.
Yet inconsistencies in food labeling make consumer choices more difficult. Emulsifiers often go by various names and appear in both organic and conventional products. For instance, xanthan gum, guar gum, and carrageenan are found in items ranging from salad dressings at Whole Foods to frozen meals at mainstream grocery chains. This ambiguity complicates efforts to track additive consumption and evaluate health impacts.
Amid growing consumer concern and scientific scrutiny, one truth remains clear: the creamy indulgence of ice cream comes with hidden complexities. As the FDA evaluates its food safety frameworks, the industry may be forced to reconcile innovation with accountability—potentially reshaping both products and ice cream franchise costs in the years to come.
