The physical activity and nutrition-related corporate social responsibility initiatives of food and beverage companies in Canada and implications for public health
BMC Public Health volume 20, Article number: 890 (2020)
As diet-related diseases have increased over the past decades, large food companies have come under scrutiny for contributing to this public health crisis. In response, the food industry has implemented Corporate Social Responsibility (CSR) initiatives related to nutrition and physical activity to emphasize their concern for consumers. This study sought to describe the nature and targeted demographic of physical activity and nutrition-related CSR initiatives of large food companies in Canada and to compare companies who participate in the Canadian Children’s Food and Beverage Advertising Initiative (CAI), a self-regulatory initiative aimed at reducing unhealthy food advertising to children, with non-participating companies.
A cross-sectional study was conducted in 2016. Thirty-nine large food companies, including 18 participating in the CAI, were included in the study. The webpages, Facebook pages and corporate reports of these companies were surveyed to identify CSR initiatives related to nutrition and physical activity. Initiatives were then classified by type (as either philanthropic, education-oriented, research-oriented or other) and by targeted demographic (i.e. targeted at children under 18 years or the general population). Differences between CAI and non-CAI companies were tested using chi-square and Mann-Whitney U tests.
Overall, 63 CSR initiatives were identified; 39 were nutrition-related while 24 were physical activity-related. Most (70%) initiatives were considered philanthropic activities, followed by education-oriented (20%), research-oriented (8%) and other (2%). Almost half (47%; n = 29) of initiatives targeted children. Examples of child-targeted initiatives included support of school milk programs (n = 2), the sponsorship of children’s sports programs (n = 2) and the development of educational resources for teachers (n = 1). There were no statistically significant differences in the number of CSR initiatives per company (CAI: Mdn = 1, IQR = 3; non-CAI: Mdn = 0, IQR = 2; p = .183) or the proportion of child-targeted initiatives (CAI: 42%; non-CAI: 54%; p = .343) between CAI and non-CAI companies.
Food companies, including many that largely sell and market unhealthy products, are heavily involved in physical activity and nutrition-related initiatives in Canada, many of which are targeted to children. Government policies aimed at protecting children from unhealthy food marketing should consider including CSR initiatives that expose children to food company branding.
Alarmingly, rates of obesity and nutrition-related noncommunicable diseases (NCDs) have been increasing globally in the past few decades [1,2,3]. In Canada, the percentage of the childhood population aged 13 years and younger with obesity has tripled between 1981 and 2011 . Although childhood obesity rates have plateaued in high-income countries in recent years, they continue to increase dramatically in low and middle-income countries . These trends are concerning as obesity, in addition to being a disease, is also a major risk factor for other serious illnesses such as diabetes, liver and cardiovascular disease, and certain cancers [5, 6]. In addition to the social inequities which contribute to poor diet and obesity [7, 8], the predominantly unhealthy nature of the food supply is likely a major contributor to this public health crisis [9, 10]. As a result, large food and beverage companies have been criticized for their role in the development of these diseases [6, 11].
In response to mounting scrutiny, the food industry has adopted self-regulatory measures and initiatives to emphasize their concerns about the health and well-being of consumers . For many companies, these activities fall under their Corporate Social Responsibility (CSR) which they define as their “economic, legal, ethical, and philanthropic responsibilities to society and their shareholders” . Many CSR activities put forth by large food and beverage companies are related to physical activity and nutrition. These include providing nutritional information for consumer education, selling healthier food alternatives, partnering with non-profit organizations and charities, sponsoring community activities and sports programs, and funding research in the fields of nutrition and physical activity .
Numerous issues have been raised regarding the effectiveness and genuine intentions of these programs with some suggesting that these activities are in fact marketing or public relation tactics employed by companies to portray themselves in a positive light [12, 14,15,16,17,18]. For instance, the unhealthy nature of many items marketed by these companies runs contradictory to the healthy living ideals of many of their CSR initiatives. Research has shown that CSR programs can create a “health halo” and associate companies with positive health attributes . Others have also drawn parallels between the food industry’s self-regulatory measures and those employed by the tobacco industry decades ago to deflect criticism and delay government intervention [12, 19, 20]. One such initiative includes the voluntary restriction of unhealthy food and beverage advertising to children. Since the late 2000’s, food and beverage companies in the United States, Australia, Norway, and Canada, among others, have developed self-regulatory (industry-led) or co-regulatory arrangements (i.e. self-regulation developed with or requested by government) to limit unhealthy food and beverage marketing to children [21, 22]. In Canada, for example, the Children’s Food & Beverage Advertising Initiative (CAI) involves 18 large food and beverage companies who have voluntarily pledged to not advertise unhealthy foods to children younger than 12 years .
While a few studies have characterized food industry CSR initiatives, particularly in Australia [12, 24], no such research has been done in Canada. The purpose of the current study was to examine the nature and targeted demographic of physical activity and nutrition-related CSR initiatives of large food and beverage companies in Canada and to compare the initiatives of CAI companies and those of non-CAI companies who advertise to children. It was hypothesized that companies participating in the CAI would be less likely to be involved in CSR activities that are child-targeted given their commitment to reduce marketing to children.
Study sample and data collection
This study examined the CSR initiatives of 39 companies including the 18 food and beverage companies participating in the CAI in 2016 and 21 non-participating companies . The latter companies were selected from May 2013 Neilsen Media Research data, based on their rank as the top food and beverage advertisers on 4 selected children and youth television stations broadcasted in Toronto, the most populous city in Canada. To identify CSR initiatives, research assistants consulted the Canadian website of each company (A.K.), their associated Canadian brand websites (A.K.), their Canadian Facebook pages going back 1 year (A.K.), if available, and their Canadian annual corporate reports (K.G.) and recorded their description. Data from Facebook pages and websites were collected from June to August 2016 while corporate CSR reports from 2016 were reviewed in April 2018.
When identifying initiatives, the following information was collected from the websites and inputted into a spreadsheet, if available: the name of the food and beverage/fast food company, the name of the initiative, the date of initiative announcement, the product highlighted or advertised through the initiative (i.e. the specific brand involved), the collaborators (e.g. community associations, school programs, non-profit organizations, government, universities etc.), and a brief summary of the initiative (found on the company website, Facebook page or on the sponsored activity’s website).
Identified CSR initiatives were categorized as either physical activity or nutrition-related. Initiatives related to physical activity included those related to sports or physical activity (for example, sponsorship of sporting events) while nutrition-related initiatives included any initiative related to nutrition or healthy eating (for example, funding nutrition research, donations to breakfast programs or the dissemination of nutrition information). If a CSR initiative was related to both nutrition and physical activity, it was coded based on the component that was sponsored by the company or, if the latter did not apply, based on the predominant nature of the initiative. If the physical activity-based initiatives mentioned the use of professional athletes as ambassadors, this was also noted.
An initiative was coded as child-targeted if “children”, “teen”, or “youth” were explicitly mentioned in the initiative description, if the targeted age group included children aged 17 and under, if the sponsored activity implied that children were targeted (e.g. sponsorship of initiatives in schools, during spring break or involved the development of branded school materials) or if the activity supported children’s charities (e.g. UNICEF). The remaining initiatives were considered targeted at the general population.
CSR initiatives were also coded into categories describing the type of activities supported or conducted by the food and beverage company. They were categorised as “education-oriented” if they aimed to disseminate information about nutrition or physical activity to consumers or health professionals (e.g. blogs/recipes, websites about nutrition, ad campaigns), as “research-oriented” if they involved funding research or as “charity/philanthropy” if the initiative supported or sponsored programs, events, charities, organizations, or fundraisers related to nutrition or physical activity (e.g. charitable donations to food banks, sponsorship of sports teams and school programs, etc.). Initiatives that did not fall into these categories were categorized as “other”.
The CSR initiatives were coded by two-trained research assistants (E.P. and K.G.). The inter-rater reliability for the nature of the initiative (nutrition or physical activity), the target population (children or general), and the type of initiative (education, research, charity/philanthropy or other) were 97, 89, and 87%, respectively. These were calculated using the following formula: 1 - (n disagreements/63 initiatives). Disagreements were reviewed by the lead author (MPK) and one of the primary coders (E.P.) and the correct coding was determined through discussion. Statistical analyses were conducted using SPSS version 25.
Identified initiatives were described using frequencies. The average and median number of CSR initiatives per company was determined and the characteristics of these initiatives were described using frequencies. A qualitative description of CSR initiatives is also provided by type of initiative. The difference in the number of CSR initiatives per company by CAI participation was examined using a Mann-Whitney U test while differences in the proportion of child-targeted initiatives and nutrition versus physical activity related initiatives were examined using chi-square tests. A p-value lower than 0.05 was considered statistically significant. Examples of products promoted through CSR initiatives are provided by CAI and non-CAI companies.
A total of 157 websites, 131 Facebook pages, and 5 reports were identified and analyzed as shown in Table 1. The list of consulted websites, Facebook pages and Canadian annual reports are listed in Supplementary Table 1.
Frequency and nature of identified CSR initiatives
Overall, it was identified that the 39 companies participated in 63 CSR initiatives, of which 29 (47%) were child-targeted. Twenty-four (38%) CSR initiatives were physical activity-related while 39 (62%) were nutrition-related. Most identified CSR initiatives were considered charitable and philanthropic activities (n = 44; 70%), followed by education-oriented (n = 13; 20%), research-related (n = 5; 8%) and other (n = 1; 2%) (Table 2).
Description of identified CSR initiatives by type of activity
Identified CSR initiatives are described in Table 3. Charitable and philanthropic CSR initiatives related to nutrition (n = 20) involved the support of school milk programs (n = 2) and various international, national and provincial organizations (e.g. World Food Program, Food Banks Canada, Breakfast Club of Canada, Foundation OLO; n = 16) or local programs (e.g. Brandon’s Food For Thought Breakfast and Snack Program; n = 2) addressing short-term food security. Forms of support to these organizations included financial contributions, food donations (e.g. milk, yogurt, breakfast cereal), and an industry-led fundraiser (e.g. Toonies for Tummies organized by the Grocery Foundation). Charitable and philanthropic CSR activities related to sports or physical activity (n = 24) included corporate philanthropy programs that provide funding or sports equipment to schools, teams or community organizations (e.g. Canada Dry Mott’s ACTION Nation program; Nestlé’s Good Food, Good Life Community Program) (n = 3), the distribution of grants to young female athletes or teams (n = 1), and the sponsorship of races, events or fundraisers (n = 10), children’s minor sports programs (n = 2; e.g. Timbits Minor Sports Program) as well as non-profit organisations promoting physical activity among youth (n = 2) (e.g. ParticipAction, Grand Défi Pierre Lavoie), among other initiatives. Two companies (Danone & McDonald’s) reported having professional athletes as ambassadors for one of their CSR initiatives targeting children.
The education-oriented CSR initiatives included nutrition information and/or recipes provided on company websites (n = 8), participation in a National Nutrition Facts Education Campaign (n = 3), the development of educational resources for teachers (n = 1) and funding for EatTracker (n = 1), a consumer resource developed by Dietitians of Canada that helps track nutrient intake.
A total of 5 initiatives were research-related and mostly involved industry funded non-profits (e.g. The Danone Institute of Canada, the Canadian Foundation for Dietetic Research) or research institutes (e.g. the Gatorade Sports Science Institute) which provide grants and awards for research related to nutrition.
The one initiative classified as “other” involved the reformulation of products to reduce their content in sodium.
Comparison between the CSR initiatives of CAI and non-CAI companies
Companies participating in the CAI accounted for 57% of identified CSR initiatives (n = 36) while non-CAI companies accounted for 43% (n = 27). As shown in Table 2, CAI companies had a median number of 1 initiative per company (IQR = 3) while non-CAI companies had a median number of 0 (IQR = 2). This difference was not statistically significant (U = 237; z = 1.434; p = .183). CAI companies had a higher proportion of nutrition-related initiatives (72%) and a lower proportion of child-targeted initiatives (42%) compared to non-CAI companies (48 and 54%, respectively) however these differences were not statistically significant (X2 = 3.792; df = 1; p = .052 and X2 = .900; df = 1; p = .343, respectively).
Examples of CAI products/brands advertised through CSR activities include, among others, Gatorade (by way of sponsorship of an extreme obstacle course event & Gatorade Hockey camp), Minute Maid 100% fruit juices (through the donation to Breakfast Club of Canada), Nestle Pure Life water (via the sponsorship of a school physical activity program), and Oikos yogurt (through the sponsorship of a yoga event). Examples of non-CAI products/brands promoted through CSR include Swiss Chalet Restaurants (via the sponsorship of children’s skiing competition and a fundraiser for cancer research involving a 2-day cycling event) and Island Farms Milk (by way of donation to school programs), among others.
Among the 39 large food and beverage companies examined, sixty-three CSR initiatives related to nutrition and physical activity were identified on company websites, Facebook pages and annual reports. Most of these initiatives were considered philanthropic or charitable activities which included support to various local, provincial and national organizations and programs, particularly those addressing short-term food insecurity or promoting physical activity among children and youth. Some companies also engaged in nutrition education by providing information on their websites, creating resources for teachers and sponsoring a national consumer education campaign.
Unfortunately, many products sold by the examined food and beverage companies are thought to be incongruent and sometimes in conflict with the health-oriented nature of their CSR initiatives. As such, these initiatives may associate participating companies and their products or brands with positive health attributes, a phenomenon known as the “health halo” effect . Indeed, research has shown that consumers make inferences about the attributes of products based on the perception and reputation of the CSR initiatives with which they are associated . This may impact the consumption choices of those targeted by these initiatives, including children. In fact, CSR initiatives have been shown to be economically beneficial for food and beverage companies and generate increased profits through brand awareness and the health halo effect .
CSR initiatives and children
Overall, our study identified 29 physical activity and nutrition-related CSR initiatives targeting children or youth including, among others, the sponsorship of junior sports teams, events and athletes, financial or food donations to school breakfast programs, and the development of nutrition education materials for school teachers. Though some of these initiatives are less likely to expose children and youth to the products or branding of supporting companies (e.g. financial contribution to children’s charities), many others, such as the sponsorship of children’s sports teams and food donations to school nutrition programs, give food companies the opportunity to directly market to this vulnerable population. In fact, food and beverage marketing, much of which promotes unhealthy products, has been established as a determinant of children’s food preferences and dietary behaviors [27,28,29,30]. Research has shown that older youth are also uniquely susceptible to the influence of marketing [31, 32].
Our findings suggest that the practice of promoting physical activity among children and sponsoring their sporting activities is widespread. This is not surprising given that marketing to children and youth through sports has been identified as a particularly powerful marketing technique . Indeed, research on alcohol and tobacco company sponsorship of sporting events has shown that this promotional technique is effective at increasing brand recognition as well as fostering positive attitudes among children and youth towards promoted products or brands . As for food company sponsorship, Kelly et al. (2011) found that most children aged 10–11 years could recall the sponsor of their sports team, held favorable views about this sponsor and said they would like to buy the sponsor’s products to “return the favour” . Similarly, a Canadian study investigating the food experiences of adolescent hockey players revealed that Tim Hortons’ (a large coffee/donut chain) sponsorship of their childhood hockey team had fostered sentiments of loyalty among these youth as well as a desire to support the restaurant in return . In addition to sponsorship, two companies, namely Danone and McDonalds, were also identified as using professional athletes as ambassadors for their initiatives. These types of endorsement strategies are particularly persuasive among children . Unsurprisingly, the use of celebrity athletes has also been shown to have a “health halo” effect whereby influencing the perceived healthfulness of food products, even among adults . By focusing on sports, food companies are shifting the emphasis of healthy living towards physical activity rather than diet. This tactic is common among food and beverage companies as it deflects attention away from their own role in the growing rates of obesity and nutrition-related NCDs and shifts blame onto individuals and their sedentary lifestyle [18, 38, 39].
Consistent with other research [40, 41], we also identified one industry association (Dairy Farmers of Canada) that has developed nutrition education materials for use by teachers, from kindergarten to high school . Though it is not known how widespread their use is, anecdotal evidence suggests that branded educational activities created by food companies are indeed making their way into Canadian classrooms, sometimes unbeknownst to parents . Several companies also reported donating food to school nutrition programs. This may expose children to branded food packaging, an important source of marketing exposure among children  and may develop their preferences for donated foods or food categories. This is concerning, particularly if promoted products are unhealthy, as such promotion within schools may create conflicting messages about healthy eating and is antithetical to a school’s mandate to educate and ensure the welfare of students . Children from lower socioeconomic status backgrounds may also be disproportionately impacted by this form of marketing as they likely receive the greatest assistance from these food programs. This may further propagate health inequities among children from lower socioeconomic backgrounds [46, 47]. To our knowledge, no research has examined the nutritional quality of products donated to school nutrition programs. Protecting children from the possible commercial interests of food companies donating food to school nutrition programs provides another argument in support of a government-funded national school food program that many organizations and academics are currently advocating for in Canada [48, 49].
This study also found that companies participating in the CAI were engaged in child-targeted CSR initiatives. For instance, four CAI companies were identified as supporting school nutrition programs, including Coca-Cola and Danone who donate fruit juice and yogurt, respectively, to a charity called Breakfast Club of Canada. Three companies also supported physical activity and sports among children under 12 years, namely Danone who has held a branded international soccer tournament (Danone Nations Cup) for children between the ages of 10 and 12 years, and McDonald’s who sponsors amateur hockey leagues for children aged 10 to 11 years [50, 51]. Though these initiatives do not contravene the pledges made under the CAI, they certainly highlight its inadequacies. Coca-Cola, for example, has pledged to not advertise directly to children in various media and in schools. However, charitable activities are explicitly excluded from the scope of prohibited activities . The company’s donation of fruit juice to school nutrition programs could be considered a form of marketing, much like the distribution of free samples, and may expose children directly to their branded products and promote a food (i.e. beverages with free sugars) that is already overconsumed by Canadian children . The promotion of CAI company brands through sports sponsorship and other health-related CSR initiatives is also problematic. The “health halo” effect created by these initiatives likely extends to all products under the same brand, including those considered unhealthy or uncompliant with the CAI’s own nutrition criteria. As such, these activities undermine the stated purpose of the CAI of promoting healthy choices and lifestyles. The scope of the CAI also excludes the protection of older youth, who are also being targeted by the CSR initiatives of CAI companies including Coca-Cola (e.g. ParticipAction) and PepsiCo (e.g. Gatorade sponsored hockey camp .
Cross-sector engagement and conflicts of interests
Our findings also revealed several instances of cross-sector engagement between food companies and governmental and non-governmental organizations. For instance, three examined companies advertised their participation in the Nutrition Facts Education Campaign on their websites. This national campaign promoted the use and understanding of nutrition labels from 2010 to 2015 and was part of a broader partnership between Food and Consumer Products of Canada, an industry interest group, and Health Canada, the government department responsible for “helping Canadians maintain and improve their health” [54, 55]. This campaign exemplifies the food industry’s tendency to frame obesity as a matter of personal responsibility [18, 38, 39]. Governmental and health organizations should reconsider partnerships of this kind as these may undermine their public image.
Overall, there is much debate regarding the role the food industry should play in the prevention of obesity and NCDs and the appropriateness of cross-sector engagement in this area [56, 57]. Many oppose partnerships between food industry and health organizations because of inherent conflicts of interests [39, 58, 59]. In addition to potentially compromising the credibility of health organizations, partnering with food companies, particularly those that largely produce and promote unhealthy food products, could confer an aura of healthfulness, goodwill and credibility to these industry partners while eclipsing the fact that many of the same companies or their industry associations persistently and aggressively push-back against government policies and the efforts of public health advocates aimed at improving diet and health [60,61,62]. Some argue that cross-sectoral partnership may also distort the priorities of beneficiary organizations and lead to self-censorship. They may also facilitate industry’s access to regulators or public health leaders whereby increasing opportunities to influence decision-making [56, 57]. As such, the beneficiaries of food industry funding and support should consider the unintended consequences and conflicts of interests that arise from engaging with the food industry and should carefully weigh the risks and benefits associated with such engagement.
Several food companies were also identified as being involved in CSR initiatives that address short-term food insecurity. Their support took on many forms including financial contributions, food donations and participation in a national fundraising campaign called Toonies for Tummies led by the Grocery Foundation . Some argue that such programs reinforce misconceptions about the causes of hunger among the public. Although these programs do meet short term needs, they shift the narrative about the cause of food insecurity towards food shortages rather than emphasize social issues such poverty and powerlessness . They also allow food companies dependant on cheap labor, such as fast food restaurants and grocery chains, to portray themselves as part of the solution while contributing to the issue with their low employee wages . Furthermore, the act of donation itself may not be a wholly selfless practice. Canadian research suggested that food companies or retailers may use food bank donations to dispose of sub-retail standard food products and reduce costs related to waste removal .
Corporate contributions to research funding
Unsurprisingly, some food and beverage companies were also found to provide funding for nutrition and physical activity research. The appropriateness and potential hazards associated with accepting research funding from the food industry is a subject of debate among researchers [66,67,68,69]. Legitimate concerns have been raised regarding the risk of conscious and unconscious bias that can result from accepting industry funding . Some evidence has in fact suggested that industry funded research more often lead to conclusions that are in favour of sponsors’ interests. This is particularly true of research examining the link between sugar-sweetened beverages and nutritional health (e.g. [70, 71]). Food and beverage companies have also been accused of using research to emphasize the lack of physical activity as the cause of obesity to shift blame away from their own products [18, 38, 39]. For example, publications funded by Coca-Cola have been shown to emphasize physical activity over sugar intake in relation to weight gain and obesity .
Recently, Serôdio, McKee, and Stuckler (2018) also noted a lack in transparency in industry influence on nutrition research literature . In 2015, Coca-Cola published a “Transparency List” of funded research in the USA. However, this list does not seem to comprehensively declare all sponsored activities; 471 authors in 128 studies did not appear in the “Transparency List” but declared funding from Coca-Cola . The reverse was also found to be true with 38 authors listed on Coca-Cola’s “Transparency List” who did not declare any conflicts of interest . This lack of transparency in research funding combined with the biases in funded research has large public health implications. For instance, industry funding could threaten the advancement public health by potentially compromising the reputations of industry-funded researchers and decreasing confidence in their findings due to real or perceived conflicts of interest . It may also divert efforts and resources away from research that is more relevant to public health .
Strengths and limitations
Limitations to the current study must be noted. The companies we examined were not randomly selected; we selected companies committed to the CAI initiative and the top food and beverage advertisers on four selected child and youth television stations. The selection of the latter companies was also made based on media data from 2013 while data on CSR initiatives were collected in 2016. The statistical analyses testing differences between CAI and non-CAI companies should also be interpreted with caution. Each CSR initiatives was counted as one initiative even though they varied widely in nature and scope. In addition, documentation of CSR initiatives was limited to those reported on the company websites, Facebook pages, and corporate annual reports published during a limited time period. This may not represent the true number of initiatives undertaken by these companies as many CSR initiatives can be specific to local communities. Furthermore, the announcement dates of many initiatives identified in this study were not specified. Therefore, it is unknown if all initiatives were being carried out at the time of the study. To get a more comprehensive picture of these initiatives, future research should consider examining additional sources of information such as media articles and industry association websites. Despite these shortcomings, this is one of the few studies to assess food industry CSR initiatives in Canada .
Studies have shown that existing self-regulatory marketing pledges have not significantly improved public health outcomes and that the private sector needs to be held more accountable . Most relevant to the current study, research has shown that self-regulatory initiatives such as the CAI have failed to reduce unhealthy food and beverage advertising to children and legislative restrictions have been proposed as a solution [75,76,77]. Given that some CSR initiatives expose children to branded products and food company branding, these activities are akin to marketing and should therefore be considered for inclusion in statutory restrictions of unhealthy food marketing to children. The monitoring of CSR initiatives targeted at children is also recommended in order to track any changes in company practices over time.
However, any policies that restrict CSR initiatives of food and beverage companies such as sports sponsorship or donations to food banks would require alternative funding mechanisms; otherwise, these policies may be unpopular and supported programs may not be sustainable . In the past, tobacco and alcohol companies have been prohibited from sponsoring ski events due to it being “not consistent with a healthy family sport like skiing” , in a similar fashion, the CSR initiatives of the food industry are not consistent with a healthy lifestyle. A case can be made for encouraging non-food and beverage companies to sponsor health related initiatives and programs. In this way, conflicts between the business interests of sponsoring companies and the public health objectives of sponsored initiatives can be minimized. Advocacy for increased government funding for these programs and for research is crucial as well.
