The Coca-Cola Company has paid €8 million to dozens of scientific and medical organizations in Spain between 2010 and 2017, according to the beverage giant’s own figures.
But a study published by the European Journal of Public Health (EJPH) finds that “research funded by the company is serving its commercial objectives that, in many cases, are at odds with efforts to improve population health.”
Scientists who work in public health cannot have conflicts of interest

The biggest beneficiaries of Coca-Cola’s research funds were the Ibero-American Nutrition Foundation (€835,000), the Spanish Heart Foundation (€640,000) and the Spanish Nutrition Foundation (€567,000). Also listed is the SHE Foundation (€363,000), which is headed by the cardiologist Valentín Fuster.
“Nutritional and cardiology organizations received the highest financial support,” says the study, signed by Juan Pablo Rey-López of Sydney University and Carlos Alberto González of the Catalan Institute of Oncology.
The World Health Organization (WHO) has urged governments to raise the price of sugary drinks by at least 20% in a bid to reduce consumption, which is linked to a global epidemic of obesity. And a team from the Harvard School of Public Health (HSPH) estimates that “roughly 180,000 obesity-related deaths worldwide are associated with the consumption of sugary drinks.”
Their research linked sweetened beverages to 133,000 diabetes deaths, 44,000 deaths from cardiovascular diseases, and 6,000 cancer deaths. There are 106 grams of sugar in one liter of Coca-Cola Classic.
“Nobody could picture Marlboro sponsoring a gathering of the Spanish Society for Medical Oncology,” notes Carlos Alberto González, an epidemiologist who co-wrote the EJPH study.
González and his colleague Rey-López analyzed 20 scientific papers that were sponsored by Coca-Cola, and found that 14 of them “were aligned with marketing strategies used by Coca-Cola (e.g. focusing on physical inactivity as the main cause of obesity).” The other six papers were more neutral in their conclusions.
Sources at The Coca-Cola Company said that the independence of scientific societies and universities “is guaranteed in all partnerships,” and noted that this sponsorship is declared annually as “an exercise in transparency.”

“Coca-Cola is copying the strategies of the tobacco industry,” says González, who in 1992 was in charge of coordinating the Spanish contribution to the WHO’s European Prospective Investigation into Cancer and Nutrition (EPIC) study.
González and Rey-López mentioned a recently aired email exchange between two former vice-presidents of Coca-Cola – Michael Ernest Knowles and Alex Malaspina – as evidence of the industry’s efforts to influence scientific organizations. “We have good contacts in some [medical associations] and we should encourage them to address public health matters and ‘suggest’ appropriate topics,” says one message from Knowles to Malaspina.
In Spain, Coca-Cola has given €420,000 to the Spanish Society for Community Nutrition, €400,000 to the Spanish Society of Primary Care Physicians, €357,000 to the Diabetes Foundation and €350,000 to the Spanish Pediatrics Association. The funds are typically used to organize symposiums and conduct scientific research. It is a regular practice at food multinationals such as Danone and at some of the beer industry’s largest companies.
“I am an independent scientist. Coca-Cola has never told me what to do,” says Marcela González Gross, a professor at Madrid Polytechnic University, an institution that has received €243,000 from the beverage company. González Gross is the main author of the Food Pyramid Study, funded with €13,700 from Coca-Cola.
“Children like to consume different kinds of drinks, especially sweet ones such as juices and sodas. This is because they have a taste preference for sweet foods, and because their energy needs are greater than adults’. These drinks can be offered in moderation, but should not be the only ones they consume,” reads a guide for parents written by González Gross and available on the Coca-Cola website.
As for Gregorio Varela, president of the Spanish Nutrition Foundation, he does not believe that the €567,000 his organization has received from Coca-Cola is harmful to its image. The money, he says, was used to finance the scientific study ANIBES, which pools data about food, nutrition and physical activity in Spain. “The subgroup made up of sugary drinks makes up 2.0 % of total energy intake (36 kcal/day out of a total of 1,810 kcal/day),” reads one of the reports.
“A study of this scope could not have been done without support from Coca-Cola,” says Varela, a professor of nutrition at CEU San Pablo University who feels that sweetened drinks “in excessive amounts are no doubt bad for public health, but consumed from time to time, it doesn’t have to be that way.” Varela does not feel the need for a tax on sugary drinks in Spain.
“Coca-Cola Spain offers an alternative with no added sugar in each of its brands, it is reducing the sugar content in its classic varieties, and it has designed new, smaller containers to reduce the sugar intake per consumption unit,” say sources at the company. “In the last 17 years we have managed a 45% reduction in the sugar content per liter in total sales for Coca-Cola Spain. In fact, 38% of sales of Coca-Cola in Spain are for products without added sugar.”
“I don’t think any food is bad for your health unless you consume it in inappropriate amounts. Sugary drinks should be consumed sporadically. I can drink an horchata, which also has 10% sugar content, or a Coke,” says the biologist Ángel Gil, who teaches at Granada University and presides the Ibero-American Nutrition Foundation.
The foundation manager, Miguel Fernández, notes that the amount they have received from the beverage company is €123,000 lower than listed on the company website (€835,000). A third of these funds were allotted to a traveling exhibition, Nutrición, impulso vital, meant to encourage healthy habits. Ángel Gil feels that “we should demand that Coca-Cola and Pepsi reduce sugar content,” but he, too, opposes the WHO recommendation of a tax on sugary drinks.
“Scientists who work in public health cannot have conflicts of interest; they cannot receive money from companies that are harming people’s health,” says Rey-López in a telephone interview from Sydney University. This epidemiologist says that obesity is “a socially communicable disease” that is tied to poverty. “A two-liter bottle of Coca-Cola is practically cheaper than a bottle of water. There are population segments, especially in the lower income bracket, who sit down to meals with a two-liter bottle of Coca-Cola on the table. And that is bad for one’s health,” adds Carlos Alberto González. “Partnerships between health professionals and industries that harm public health should be viewed as marketing strategies by the industry to protect its profits.”
