Coca-Cola marketing to children is “serious publichealth concern,” researchers warnElisabeth MahaseThe BMJ

Two major campaigns from Coca-Cola were targeted atteenagers and mothers and used social media influencers andcelebrities—including Olympic athletes—to make productsseem healthier, researchers have warned.US Right to Know, a non-profit investigative group thatcampaigns for transparency in the food industry, issued thewarning after it obtained documents from the University ofColorado relating to two of Coca-Cola’s public relations (PR)campaigns: the 2013-14 Movement is Happiness campaign andthe 2016 Rio de Janeiro Olympic Games campaign.The group said that, although the company was publiclypledging to reduce children’s exposure to advertisements forproducts high in fat, sugar, or salt, behind closed doors it wasactively targeting young age groups.US Right to Know called for government policy to “effectivelyrestrict the exposure of children to the marketing of unhealthyfoods” and said that PR agencies should “fall within the reachof such policy or regulatory action.”On a global level, it called on bodies such as the InternationalOlympic Committee and FIFA to “play their part in addressingthe issue at hand.” The investigative team found that the Riocampaign had directly set out to target teenagers (aged 13 to20) and mothers, through social media influencers andcelebrities. It reached 21 million teenagers (90% on mobilephone platforms), and the phase of the campaign during thegames achieved a seven point “brand lift” (a measurement ofthe increase in brand interaction) among teenagers.Perceived healthinessThe Movement is Happiness campaign also focused onteenagers, with an emphasis on increasing the perceivedhealthiness of the Coke brand. The report quoted the documentsobtained as saying, “[Coke] recognizes the importance of leadingin this [health and wellbeing] space to marginalize detractorsand build support broadly in a host of categories, includingconsumers, women, government and political officials andpersonalities, and media.”The report, published in the International Journal ofEnvironmental Research and Public Health, said, “Coke’s intentand ability to use PR campaigns to market to children shouldcause serious public health concern, given that the exposure ofchildren to the marketing of unhealthy foods is likely to be animportant contributor to increased childhood obesity rates.

“This study highlights how PR campaigns by large foodcompanies can be used as vehicles for marketing to children,and for corporate political activity. Given the potential threatsposed to populations’ health, the use of PR agencies by foodcompanies warrants heightened scrutiny from the public healthcommunity, and governments should explore policy action inthis area.”The paper said that, while Coca Cola had pledged not to directlytarget marketing at children under 12 (by not placing advertisingin media where over 35% of the audience are under 12) and toreduce children’s exposure to advertising of any products highin fat, salt, or sugar, these campaigns showed that their actionswere limited.The researchers said, “To highlight this point, if the overallnumber of children and teenagers reached by an advertisingcampaign is 21 million (the number reached by the Riocampaign), then according to Coke’s policy it would beacceptable for more than seven million of these to be below theage of 12.“Coke’s marketing strategy to directly target mothers—a tacticdescribed as one way to sidestep the issue of advertising directlyto young children—also demands further scrutiny from a publichealth perspective.”

Study limitationsA spokesperson for Coca-Cola said, “In 2017-18, we eliminated425 000 tons of sugar from our global portfolio of productsthrough innovations such as new recipes, smaller packs, andwider availability of low and zero sugar products. We arecontinuing those efforts to provide greater choice for ourconsumers.”US Right to Know’s work is funded by multiple donors,1 andthe report’s lead author, Gary Sacks, who is the organisation’sco-director, also received funding from the National Health andMedical Research Council, the Australian Research Council,the Canadian Institutes of Health Research, and the WorldHealth Organization.Limitations of the study included that it analysed only twocampaigns and that its examination was superficial, as it lookedat the campaigns’ intentions rather than how effective they were.

International Life Sciences Institute is advocate forfood and drink industry, say researchersOwen DyerMontreal

Researchers have labelled the International Life SciencesInstitute (ILSI) an industry front group, after studying thousandsof documents from the influential sponsor of published researchon nutrition and health.Writing in the journal Globalization and Health,1 researchersfrom the University of Cambridge in England, BocconiUniversity in Italy, and the US Right to Know campaign calledILSI a “case study” that “serves as a caution to those involvedin global health governance to be wary of putatively independentresearch groups.”Sarah Steele, lead author from the University of Cambridge,said, “Our findings only continue to add to the evidence thatthis non-profit organisation has been used by its corporatebackers for years to counter public health policies.“We contend that the International Life Sciences Institute shouldbe regarded as an industry group—a private body—andregulated as such, not as a body acting for the greater good.”Freedom of information requestILSI describes its mission as promoting “global partnershipsfor a healthier world” and providing “science that improveshuman health and wellbeing and safeguards the environment.”Its mission statement declares, “ILSI does not lobby, conductlobbying activities, or make policy recommendations.”But this claim, said the researchers, is undermined by over 17000 pages of emails and other documents that US Right to Knowobtained from ILSI, a non-profit organisation based inWashington, DC, through a freedom of information request.Prominent among these are the emails of Alex Malaspina, ILSI’sfounder and former vice president of Coca-Cola.Malaspina, a long time president of ILSI, corresponded with anetwork of academics, doctors, industry executives, andeventually his successors in the charity’s leadership. The groupcommented on regulatory policy and how to influence it, oftenappearing to use the terms “we” or “us” as a synonym forindustry.In one email sent after new US dietary guidelines took a strongerline on sugar, Malaspina wrote, “Dear friends, these guidelinesare a real disaster! They could eventually affect us significantlyin many ways: soft drink taxations, modified school luncheonprograms, a strong educational effort to educate children andadults to significantly limit their sugar intake, curtail advertisingof sugary foods and beverages and eventually a great pressurefrom CDC [the US Centers for Disease Control and Prevention]

and other agencies to force industry to start reducing drasticallythe sugar we add to processed foods and beverages.“Also we have to expect that many nations will follow the USguidelines. We have to consider how to become ready to mounta strong defence.”In another email he described “the mess ILSI Mexico is inbecause they sponsored in September a sweeteners conferencewhen the subject of soft drinks taxation was discussed. ILSI isnow suspending ILSI Mexico, until they correct their ways.”In other emails from 2015 Malaspina complained to BarbaraBowman, director of the CDC’s division for heart disease andstroke prevention, about the increasing coldness towards ILSIfrom the World Health Organization—whose director general,Margaret Chan, was then fashioning a harder line against sugarydrinks. He noted that he had managed to smooth relations undera previous WHO leader through direct contact but found Chaninaccessible.Current WHO leaders “do not want to work with industry,” hecomplained, adding, “Something must be done.”He suggested recruiting a top scientist or a “US governmentscientist” to approach Chan; Bowman suggested severalalternative avenues. That email exchange was published in themedia in 2016. The CDC’s Bowman, herself a former Coca-Colascientist, announced her retirement days later.2

DonationsBrenda Fitzgerald, who was appointed by President Trump in2017 to run the CDC, also corresponded frequently with ILSI’sleadership. She resigned from her CDC post after news of hertobacco investments surfaced.3

WHO was criticised in 2016 after Alan Boobis, ILSI vicepresident, chaired a meeting to establish policy on the weedkillerglyphosate. ILSI had previously taken more than $1m (£788000; !888 000) in donations from a leading glyphosatemanufacturer, Monsanto, and an affiliated lobbying group.4

WHO finally cut its formal ties with ILSI in 2017.The European Parliament temporarily suspended funding of theEuropean Food Safety Authority in 2012, after conflict ofinterest allegations surfaced involving ILSI members on itsboard.One industry leader, Mars Co, quit ILSI last year, explainingin a statement, “We do not want to be involved in advocacy-led

studies that so often, and mostly for the right reasons, have beencriticised.”A BMJ investigation in January found that staff at ILSI Chinahad “unparalleled access to government officials”—their officesare located inside the headquarters of the Chinese Center forDisease Control and Prevention—and had successfully steeredChina’s thinking on obesity prevention towards a focus onexercise and away from sugar reduction, in line with industry’sgoals.5

ILSI was approached for comment but had not responded bythe time of publication.

Coca-Cola contracts could allow it to “quash”unfavourable research findingsElisabeth MahaseThe BMJ

Coca-Cola might be able to suppress unfavourable findingsfrom health research it funds at public universities in the UnitedStates and Canada, a new study has found.1

Researchers studied over 87 000 documents obtained throughfreedom of information requests and found several clauses thatallow the drinks giant to terminate research projects withoutreason and walk away with the data.Coca-Cola funds research in the fields of nutrition, physicalinactivity, and energy balance. It publishes a list of the fundingit has allocated from 2010 to the present on its transparencywebsite.2

The research team, from the University of Cambridge, LondonSchool of Hygiene and Tropical Medicine, the University ofBocconi, and non-profit group US Right to Know, looked atfive research agreements made with four universities: LouisianaState University, University of South Carolina, University ofToronto, and the University of Washington.They found that, although the contracts show that Coca-Coladoes not have day-to-day control of the research, it has variousrights throughout the process, including the right to receiveupdates, comment on findings before publication, and terminatestudies early without reason.This is despite Coca-Cola’s website stating that “in no eventdoes The Coca-Cola Company have the right to prevent thepublication of research results.”The study, published in the Journal of Public Health Policy,argues that these measures allow Coca-Cola to prevent thepublication of unfavourable results, although to date it foundno evidence of this happening in the emails obtained.The authors are now calling on corporate funders to publishlists of terminated studies and on scientists to publish industryagreements to show that their findings are free from influence.Lead author Sarah Steele, from the University of Cambridge,said: “Coca-Cola have declared themselves at the forefront oftransparency when it comes to food and beverage giants fundinghealth research. In fact, our study suggests that importantresearch might never see the light of day, and we would neverknow about it.“We are already hearing accusations from experts in nutritionthat the food industry is copying tactics from big tobacco’s

playbook. Corporate social responsibility has to be more thanjust shiny websites stating progressive policies that get ignored.”Gary Ruskin, from US Right to Know—the group that submittedthe freedom of information requests—said: “With the power totrumpet positive findings and bury negative ones, Coke-fundedscience seems more like an exercise in public relations.”Previous correspondence between The Coca-Cola Companyand the US Centers for Disease Control and Prevention showedthe drinks giant’s efforts to influence the agency’s approach totackling obesity, including shifting blame away from sugarsweetened beverages.3

This came after a BMJ investigation found how Coca-Cola hadshaped obesity science and steered public health policy towardsits own interests in China.4

A spokesperson for the Coca-Cola Company said that thecompany had not independently funded research on issuesrelated to health and wellbeing in line with its 2016 researchguiding principles.5

They added: “Additionally, a list of health and wellbeingresearch funded by The Coca-Cola Company dating back to2010 has been disclosed on our transparency website for nearlyfour years. Research funded by The Coca-Cola Company anddisclosed on our site is expected to be conducted in accordancewith our publicly stated approach to funding scientific research,including the fact that we do not have the right to prevent thepublication of research results nor do we provide fundingconditioned on the outcome of the research.”

Coca-Cola and obesity: study shows efforts toinfluence US Centers for Disease ControlGareth IacobucciThe BMJ

Correspondence between the Coca-Cola Company and the USCenters for Disease Control and Prevention (CDC) has revealedCoke’s efforts to influence the agency’s approach to tacklingobesity, a new study has found.Published in the Milbank Quarterly,1 the paper said that emailsreveal Coke’s interest in “gaining access to CDC employees, tolobby policymakers, and to frame the obesity debate by shiftingattention and blame away from sugar-sweetened beverages.”The emails also demonstrate Coke’s efforts to “advancecorporate objectives, rather than health, including to influencethe World Health Organization,” says the study.FOI requestsThe paper follows an investigation published by The BMJ lastmonth,2 which showed how Coke had shaped obesity scienceand steered public health policy towards its own interests inChina.The latest study was based on emails and documents obtainedthrough the US Freedom of Information Act by the campaigngroup US Right to Know, which lobbies for transparency in thefood industry.3 It was jointly conducted by researchers from theLondon School of Hygiene and Tropical Medicine in the UK,Bocconi University in Italy, and US Right to Know.The team sent 10 freedom of information requests in 2016-17for communications sent between employees at the CDC andCoca-Cola. It then carried out a thematic content analysis of thedocuments provided. Of the 10 requests, three are still pending,five were rejected for being too broad or because no recordswere found, and three returned 295 pages from 86 emails. TheCDC withheld 102 pages to “protect commercial or financialinformation which is privileged or confidential.”US Right to Know sued the CDC last year over its failure torelease further correspondence between agency officials andcurrent or former Coke employees,4 and the legal action isongoing. The CDC has faced criticism in recent years for itslinks to manufacturers of unhealthy products including sugarsweetened drinks.5

Gary Ruskin, co-director of US Right to Know and coauthor ofthe paper, said, “It is not the proper role of the CDC to abetcompanies that manufacture harmful products. Congress shouldinvestigate whether Coca-Cola and other companies that harmpublic health are unethically influencing the CDC and subvertingits efforts to protect the health of all Americans.”

“Clear conflict of interest”Martin McKee, coauthor and professor of European publichealth at the London School of Hygiene and Tropical Medicine,said, “Once again we see the grave risks that arise when publichealth organisations partner with manufacturers of products thatpose a threat to health. Sadly, as this example and more recentones in the United Kingdom show, these risks are not alwaysappreciated by those who should know better.”The paper concludes, “It is unacceptable for public healthorganizations to engage in partnerships with companies thathave such a clear conflict of interest. The obvious parallel wouldbe to consider the CDC working with cigarette companies andthe dangers that such a partnership would pose. Our analysishas highlighted the need for organizations like the CDC toensure that they refrain from engaging in partnerships withharmful product manufacturers lest they undermine the healthof the public they serve.”A CDC spokesperson said, “CDC believes that public healthand scientific advancement are best served when informationis shared among other public health agencies, academicresearchers, and private researchers in an open, timely, andappropriate way. CDC professionals have numerousopportunities and extensive ethical and science-integritycheckpoints internally and externally that work to balance itsguidelines and recommendations.”A spokesperson for the Coca-Cola company said, “Over thepast four years, the Coca-Cola Company has been on a journeyto be a more helpful and effective partner in efforts to addressthe issue of obesity. We’ve listened closely to those in the publichealth community and other stakeholders to better understandthe most appropriate role we can play to support the fight againstobesity in a way that is credible, transparent, and beneficial foreveryone, and we have evolved our approach.”

Coca-Cola’s secret influence on medical and sciencejournalistsA series of journalism conferences on obesity received covert funding from Coca-Cola. Paul Thackerinvestigates

Paul Thacker freelance journalistMadrid, Spain

Industry money was used to covertly influence journalists withthe message that exercise is a bigger problem than sugarconsumption in the obesity epidemic, documents obtained underfreedom of information laws show. The documents detail howCoca-Cola funded journalism conferences at a US university inan attempt to create favourable press coverage of sugarsweetened drinks. When challenged about funding of the seriesof conferences, the academics involved weren’t forthcomingabout industry involvement.For drinks manufacturers such as Coca-Cola the idea thatconsuming their products is fine as long as youexercise—reinforced with expensive advertising campaignsassociated with sport—has been an important one. As YoniFreedhoff, assistant professor of medicine at the University ofOttawa, told The BMJ, “For Coca-Cola the ‘energy balance’message has been a crucial one to cultivate, as its underlyinginference is that, even for soda drinkers, obesity is more aconsequence of inactivity than it is of regularly drinking liquidcandy.”The six figure bill for funding these journalism conferences wasmore than repaid in favourable press coverage, say critics.Documented evidence of the industry’s covert influence on themedia is rare. In 2004, researchers examined secret documentsmade public during tobacco litigation. Attempting to derail theeffect of the US Environmental Protection Agency’s 1993 reporton secondhand smoke, the tobacco industry successfully placedstories in major print publications about the report’s “scientificweakness” to help “build considerable reasonable doubt . . .particularly among consumers,” the researchers wrote.1 Theyconcluded that even journalists can fall victim to wellorchestrated public relations efforts, regardless of the qualityof the science used in these PR exercises.Coca-Cola funding at the University ofColoradoThe story begins with articles last year in the New York Timesand Associated Press on the Global Energy Balance Network,a now defunct “science based” collaboration between Coca-Cola

and university scientists to tackle the obesity crisis.2 Thecompany donated $1m to the University of Colorado, homeinstitution of the Global Energy Balance Network’s president,James Hill, a professor of paediatrics. After experts criticisedthe network as a Coca-Cola ploy to shift the public’s perceptionof the causes of obesity from diet and consumption of sugarydrinks to lack of exercise, the network shut down in December2015. The University of Colorado later returned the money toCoca-Cola, and the company now declares its funding to externalorganisations on a website.Not yet reported are several journalism conferences theUniversity of Colorado ran with funding from Coca-Cola.Emails and documents obtained by The BMJ under freedom ofinformation laws show that Coca-Cola began approachingprofessors at the university in early 2011 in an attempt to swayjournalists. The tactic bore fruit. In one example, a CNN reporterattended the 2014 journalism conference and later contributedto a story that argued that obesity’s cause could be lack ofexercise, not consumption of sugary soft drinks. Critics toldThe BMJ that Coca-Cola’s $37 000 support for that particularconference and the resulting story was a better bargain than anadvertisement placed on CNN’s website.Emails between Hill and Coca-Cola in 2011 detail the planningfor a journalism conference that took place in early February2012. Almost 20 journalists attended the conference, withassistance from the non-profit, Washington DC based NationalPress Foundation.Some months after the event, Hill emailed a Coca-Colaexecutive and described the conference as a “home run,” adding,“The journalists told us this was an amazing event and theygenerated a lot of stories.” Hill continued, “You basicallysupported the meeting this year . . . I think we can get manymore sponsors involved next year.”Months later, the company agreed to send $45 000 to theUniversity of Colorado Foundation for further support.In August 2013 Hill emailed Coca-Cola about anotherjournalism conference on obesity held with the National Press

Foundation. Emails and questions to the foundation suggest thatit did not know about these conversations with Coca-Cola. Hillwrote to the company: “The conference was a great success andeven better than last year. These journalist[s] came away witha much more realistic understanding of obesity. Thanks againfor your support.” Hill apparently attached a report of theconference, as a Coca-Cola executive responded, “Have readthe entire [report]—excellent. Count us in for next year.”

Journalist complainsBut one journalist, Kristin Jones, became concerned about howthese conferences were funded and complained to the NationalPress Foundation. The foundation’s president, Bob Meyers,passed on her concerns to Hill and fellow professor John Peters.Meyers told the professors that Jones was upset to hear thatCoca-Cola provided $10 000 for the 2014 journalism conference,which she attended, and added that he had told Jones “that allwe know about funding is that it came from the University ofColorado Foundation.”Peters then told the National Press Foundation by email, “Thefunding for this came from our general educational grantresources.” Months later, Peters emailed Coca-Cola executivesa report on the 2014 journalism conference, thanking them forthe “educational grant that supported this work.”“I feel like I was lied to,” Jones told The BMJ. Jones no longerworks as a journalist but said that she would not have attendedthe conference had she known of Coca-Cola’s funding.The National Press Foundation’s detailed report of the 2014conference included comments from reporters who attendedand listed stories they later wrote. At the top of the report is aprominent quote from reporter Jen Christensen of CNN: “Youhad all the rock stars of the obesity topic—the quality of thespeakers you chose was incredible. Never have I been to sucha helpful fellowship.” The report notes that, months after theconference, Christensen contributed to a CNN story titled, “Sodamakers want to cut calories, but is diet really better?”3

Christensen did not return repeated requests to comment forthis story, nor did a reporter from National Public Radio whoalso attended.

“Great business”Ottawa University’s Yoni Freedhoff commented, “It’s greatbusiness for Coca-Cola to fund the indoctrination of journalistsin Coca-Cola friendly dogma, a fact I’d wager was clear to thoseexperts who helped Coca-Cola to hide their involvement.”The organiser of the conferences for the National PressFoundation was Bob Meyer, who has left the group. He did notrespond to requests for comment. The foundation is now runby Sandy Johnson, who said by email that “a more appropriatesponsor of a journalist training program would be an

organization such as Mayo Clinic, which did just that inFebruary 2016.”After reviewing several of the documents obtained by The BMJ,including the final 2014 report, Marion Nestle, professor ofnutrition and public health at New York University, said thatjournalists should have realised that the programme was anindustry event because of the choice of speakers and topicscovered. One panel, for instance, featured representatives fromMcDonald’s and Coca-Cola discussing their corporate initiativeson obesity. Journalists appear to have been misled, but theyshould not have been so gullible, Nestle added. “Overall, thislooks like an industry meeting framed as science, and thejournalists bought into it. Coca-Cola got its money’s worth onthis one.”A Coca-Cola representative said that in September 2015 thecompany disclosed on its website the $45 000 funding to theUniversity of Colorado for the journalism training programmein the spring of 2012. Before 2015 it wasn’t clear where thefunding for the journalism programme was coming from. TheUniversity of Colorado told The BMJ that the university fundedthe 2014 journalism conference with $37 500 provided primarilyby Coca-Cola Company for the Global Energy Balance Network.A university spokesperson told The BMJ, “Essentially fundingfor the conference came from a gift from Coke.”Hill and Peters have not responded to The BMJ’s requests forcomment.

Conflicts of interest compromise US public healthagency’s mission, say scientistsJeanne Lenzer

New York

Scientists at the United States’ public health agency have urgedtheir employers to “clean up this house,” claiming that conflictsof interest are undermining trust in the agency.1

The scientists at the Centers for Disease Control and Preventionin Atlanta, Georgia, sent an anonymous letter at the end ofAugust to Carmen S Villar, chief of staff at the CDC’s Officeof the Director. They wrote, “It appears that our mission is beinginfluenced and shaped by outside parties and rogue interests.“This ‘climate of disregard’ puts many of us in difficultpositions. We are often directed to do things we know are notright.”They claimed that “this unacceptable behavior” was widespread,adding, “These questionable and unethical practices threaten toundermine our credibility and reputation as a trusted leader inpublic health.“We would like to see high ethical standards and thoughtful,responsible management restored at CDC. We are asking thatyou do your part to help clean up this house!”The letter highlighted links between two CDCveterans—Barbara Bowman andMichael Pratt—andCoca-Colaas some of the problems at the agency.2 3

The letter and emails revealing internal problems at the CDCcame to light after US Right to Know, a watchdog organizationfocusing on food and agricultural issues, filed freedom ofinformation act requests relating to Bowman and Pratt.Bowman, until recently the director of the agency’s Divisionfor Heart Disease and Prevention, joined the CDC in 1992 afterworking as a senior nutritionist at Coca-Cola. She continuedher ties with Coca-Cola while at CDC through the InternationalLife Sciences Institute, an industry front organization whosemembers includemultiple soda companies, includingCoca-Cola,and the agricultural giant Monsanto.Bowman resigned her position at CDC at the end of June, daysafter these ties became known.4

Pratt, a senior adviser for global health in the National Centerfor Chronic Disease Prevention at the CDC, has led research

funded by Coca-Cola and has also worked closely with theInternational Life Sciences Institute. One of Coca-Cola’sstrategies to promote Coke has been to claim that exercise, notdiet, is linked to obesity and related health problems. Emailsshow that Pratt discussed this strategy in his role as adviser toCoca-Cola’s “Exercise is medicine” initiative. Pratt currentlyworks at the University of California, San Diego as a professorin the Division of Global Health.5

The letter also claimed that some resources for domestic workwere being channeled into global health issues. “These actionsdo not serve the public well,” it said. “Why is nothing beingdone to address these problems?”This is not the first time that conflicts of interest at the CDChave come to light. The agency took industry funding to supportpro-industry positions for hepatitis C screening and for the fludrug oseltamivir (Tamiflu). It also oversaw controversialresearch funded by the sugar industry that purported to exculpatethe sugar industry or minimize its role in causing deadly kidneyfailure among sugar cane workers in Latin America.6

The CDC did not respond to inquiries about the letter.

US public health agency is sued over failure to releaseemails from Coca-ColaMartha RosenbergChicago

US Right to Know, a campaign group for transparency in thefood industry, has sued the Centers for Disease Control andPrevention (CDC) over its failure to release correspondencebetween agency officials and current and former employees ofCoca-Cola requested under freedom of information rules.1

Within days of filing the suit on 21 February the group said thatit had received a small batch of new documents from the CDC.Asked whether the quick response was an attempt to stop thelawsuit, Gary Ruskin, co-director of US Right to Know, said“possibly,” but the group still sought the additional emailsspecified in the suit “to uncover the extent and nature of theCDC’s relationship with Coca-Cola.”Coca-Cola provides funding to a host of medical organizationsincluding the American Heart Association, the American LungAssociation, the American College of Cardiology, and theAmerican Academy of Pediatrics. It also contributes to HarvardMedical School/Partners in Health, other major universities,recreation and fitness groups, and ethnic and minorityorganizations.The drinks maker also funds the CDC itself through thenon-profit CDC Foundation, created by Congress in 1992 toencourage relationships between CDC and industry.2

Last year The BMJ reported on Coca-Cola’s secret influence onmedical and science journalists by funding journalismconferences, including those held by the nonprofit NationalPress Foundation, based in Washington, DC.3 US Right to Knowhopes that the lawsuit will further expose Coca-Cola’s influenceon CDC personnel and policies. “Why should the CDC letCoca-Cola lobby it?” asked Ruskin. “The government shouldnot be for sale. It is destructive of public trust.”Previous emails obtained by US Right to Know have shownthat Barbara Bowman, former director of the CDC’s Divisionfor Heart Disease and Stroke Prevention, agreed to try to helpAlex Malaspina, a Coca-Cola strategist and former executive,to soften the World Health Organization’s stance on soft drinks.WHO published a new sugar guideline in 2015 and the nextyear blamed full sugar soft drinks for rising child obesity aroundthe world, especially in developing countries.In 2014 Bowman, a former Coca-Cola employee, wrote in anemail to Wamwari Waichungo, a Coca-Cola vice president,asking him to “please change to my personal email address.”Bowman left the CDC in June 2017.

Among the current or former CDC officials whosecorrespondence with Coca-Cola the lawsuit seeks is MichaelPratt, who served as senior adviser for global health at theagency until leaving for the University of California at SanDiego in 2016.4 While working at the CDC Pratt was alsoscientific adviser to ILSI North America, a group founded byCoca-Cola’s Malaspina in 1978.5 Pratt has written at least sevenpapers funded by Coca-Cola including one in the journalObesity, which found “no significant associations betweendietary patterns and obesity” in the children studied.The theory that obesity is caused primarily by a lack of exerciserather than excessive calories—called “energy balance”—isaggressively promoted by Coca-Cola to fight falling sales. Tospread the message Coca-Cola funded the Global EnergyBalance Network, a US based nonprofit group, to the tune of$1.5m (£1.1m; !1.2m). Coca-Cola shaped the group’s messagesand content and even helped choose its leaders.6 The network,widely reviewed as a front organization, was shut down in 2015.To promote the “energy balance” theory Coca-Cola funded a$1m exercise program in Georgia overseen by BrendaFitzgerald, a health commissioner who went on to become CDCdirector. Fitzgerald said that she would continue to acceptCoca-Cola’s money as CDC director but resigned her post inJanuary because of her holding of tobacco stocks.7
