The intersection of corporate profit and public health has few starker examples than Nestlé's decades-long marketing of infant formula in Africa. From the 1970s to present-day controversies, the Swiss multinational has employed deceptive practices — including fake experts and misleading health claims — that have contributed to hundreds of thousands of infant deaths.

This tragic history, from the "milk nurses" of the past to modern double standards in product formulation, offers critical lessons about the dangers of allowing marketing to masquerade as medicine.
The Baby Killer Scandal
The most infamous chapter began in the 1970s when Nestlé faced explosive allegations that triggered one of the longest international boycotts in history. A 1977 report titled "The Baby Killer" exposed how Nestlé was causing infant deaths through aggressive marketing that actively discouraged breastfeeding.
Central to this scandal was an insidious form of fake expert marketing: Nestlé employed sales representatives dressed in nurses' uniforms to build trust among vulnerable mothers. These "milk nurses" visited hospitals presenting themselves as medical professionals while promoting formula as scientifically superior to breastmilk.
The consequences were devastating. For mothers without access to clean water — a reality for millions across Africa — mixing formula with contaminated water proved fatal. Diarrheal disease swept through formula-fed infant populations at alarming rates.
Economic research has quantified the tragedy. A study examining Nestlé's entry into low-income markets found the company's marketing caused approximately 212,000 infant deaths per year among mothers without clean water access at the peak of the controversy. Between 1960 and 2015, researchers estimate Nestlé's formula marketing led to approximately 10.9 million excess infant deaths.
The Modern Scandal: Sugar and Double Standards
While the formula controversy led to the 1981 WHO International Code on breast-milk substitutes, Nestlé's problematic practices continue. In 2024-2025, Swiss watchdog Public Eye revealed Nestlé markets fundamentally different products to African consumers than those sold in Europe.
The investigation found 94 percent of Nestlé's Cerelac infant cereals sold in major African markets contain added sugar, while the same products sold in Switzerland, Germany, and the UK contain zero added sugar. In Nigeria, laboratory tests revealed 5 to 6 grams of added sugar per serving — equivalent to one to one-and-a-half sugar cubes.
When confronted, Nestlé resorted to what Public Eye describes as a "well-worn tactic: shoot the messenger." The company claimed it was "scientifically inaccurate to refer to the sugars... as refined sugars" — a false defense, as investigators had explicitly excluded naturally occurring sugars from their analysis.
More disturbing was Nestlé's attempt to justify added sugar as a nutritional intervention, arguing sweet cereals prevent malnutrition because children "can refuse to eat." As Public Eye noted sardonically, this implies "unlike Swiss toddlers, African babies are picky eaters with a sweet tooth."
The Danger of Manufactured Expertise
The mechanism of harm operates through multiple channels. Fake expert marketing undermines informed decision-making. It displaces superior alternatives — in the formula cases, breastfeeding that would have provided complete nutrition without contamination risk. And it creates lifelong health trajectories: early sugar exposure "trains kids' palates to prefer sweetened foods," leading to preferences that exacerbate obesity and diabetes.
Pediatric guidelines recommend zero added sugar for children under two. Yet Nestlé's African products systematically violate this standard while complying with it in Europe. Sub-Saharan Africa has seen childhood obesity increase by over 20 percent in recent decades.
The Contemporary Landscape: AI Deepfakes
While Nestlé's practices represent corporate malfeasance, the fake expert phenomenon has evolved. The Australian Medical Association recently warned about "deepfake" videos that "mimic reputable health professionals" to sell unproven and potentially harmful treatments.
These AI-generated videos represent a qualitative leap in deceptive marketing. Trusted clinicians have had their identities misused in deepfakes promoting unproven products for diabetes, heart disease, and menopause. Full Fact uncovered hundreds of deepfake videos on TikTok featuring impersonated doctors directing viewers to supplement companies.
These videos "encourage consumers to abandon clinically validated therapies in favour of unscientific alternatives," warned AMA President Dr. Danielle McMullen. "Disturbingly, many health professionals only become aware they have been impersonated when patients raise questions about discontinuing their prescribed treatments."
Regulatory Gaps
A persistent theme is inadequate regulation. In Nigeria, infant food regulations still rely on Codex Alimentarius standards from 1981, which permit up to 20 percent added sugar in infant cereals — a threshold wildly inconsistent with current WHO recommendations. Nestlé claims compliance while ignoring both the science and the ethics of double standards.
Professor Chiso Ndukwe-Okafor, executive director of Nigeria's Consumer Advocacy and Empowerment Foundation, condemned the situation bluntly: "This is not a mistake, this is intentional. Nestlé knows that added sugar is unnecessary for babies, and they formulate sugar-free products for Europe. So why are African babies given one to two cubes of sugar per serving?"
Lessons for Global Health
The Nestlé tragedy offers urgent lessons. First, corporate self-regulation is insufficient when profits incentivize harm. Second, the fake expert phenomenon requires prevention and enforcement — meaning transparent identification of who is behind health messaging and meaningful penalties for violations. Third, regulatory standards must reflect current science, not historical compromises. Fourth, digital platforms must be accountable for content they host — requiring them to verify identities and remove fraudulent content promptly.
Finally, consumers in the Global South deserve the same protections as those in wealthy nations. As Professor Susana Ramírez observed, "To the extent that colonization by the food industry is destroying traditional ways of eating, I would call this food racism." The systematic formulation of inferior products for African markets, defended by expertise, represents a moral failure.
Conclusion
The thread connecting 1970s "milk nurses" in African hospitals to 2020s AI deepfakes is the commercialization of trust. When expertise can be manufactured — whether through uniforms, misleading claims, or artificial intelligence — the vulnerable pay with their health and sometimes their lives.
For Nestlé's African victims, the toll is measurable in millions of excess infant deaths. For victims of deepfake scams, it includes abandoned medical treatments and delayed care. The common denominator is exploitation of information asymmetry: sellers know what they're offering, while buyers cannot distinguish genuine expertise from performance.
As twenty African civil society organizations reminded Nestlé's CEO in 2025: "All babies have an equal right to healthy nutrition — regardless of their nationality or skin colour." Until marketing recognizes this equality, and until manufacturing fake expertise carries consequences, the danger will persist — evolving with technology, adapting to regulation, but always exploiting trust for profit.
