The rapidly growing share of ultra-processed foods (UPFs) in human diets raises serious concerns for public and planetary health [1]. According to NOVA, a widely recognised food categorising system used in multiple national dietary guidelines [2–4], UPFs are ‘formulations of ingredients, mostly of exclusive industrial use, that result from a series of industrial processes’ [5]. Common examples of UPFs include carbonated soft drinks, industrially made snacks and breads, reconstituted meat products, ice creams, confectionery, and many types of breakfast cereals [5]. UPFs are distinct from fresh and ‘processed’ foods, which include tinned, frozen, and cooked foods made using ingredients commonly found in domestic kitchens around the world.
There is a substantial and growing evidence base linking high levels of consumption of UPFs with adverse population health outcomes, including all-cause mortality, overweight and obesity, chronic diseases (e.g., heart disease, type-2 diabetes, cancer, dementia and depression), and poor pregnancy and childhood developmental outcomes [6–14]. In addition, UPF production and consumption are associated with a range of poor environmental outcomes, including high levels of plastic waste and pollution, the monocultural production of commodity crops and related impacts on biodiversity [15–18].
Unlike other foods, UPFs are exclusively made by for-profit corporations, and it is well recognised that these corporations have played a large role in driving the global UPF dietary transition [19–22]. Since the advent of ultra-processing technologies in the late 19th century, ultra-processing has become a core strategy of profit maximisation within the industrial food system [23–25]. The competitive and financial advantages that ultra-processing confers food corporations, such as by increasing product durability, as well as by facilitating product and brand differentiation, is likely one of the key explanatory factors as to why today’s major UPF corporations have been able to accrue extensive resources and capacities over a long period of time [22]. Such resources and capacities have, in turn, underpinned the deployment of diverse strategies (e.g., global expansion, aggressive marketing, lobbying) by major UPF corporations intended to shape population diets and food systems in their favour [19, 26, 27].
Corporate strategy alone, however, does not explain the global rise of UPFs. In recent years, a growing body of work has examined the ways in which various widespread and interlinked processes have facilitated the global UPF dietary transition by shifting institutional and governance arrangements towards accommodating, rather than constraining, the power and legitimacy of UPF corporations [19, 20]. Such processes include, inter alia, the industrialisation of food systems, economic globalisation, trade and investment liberalisation, and increases in multi-stakeholderism. While these processes influence countries and social groups in different ways, exploring their role in driving the global UPF dietary transition can help to shed light on various structural and transformative changes with the potential to curb the global UPF dietary transition [20, 28].
A key capitalist process that relates to, and in some ways underpins, many of the above-mentioned processes is ‘financialisation’. Epstein (2005) refers to financialisation as the ‘increasing role of financial motives, financial markets, financial actors and financial institutions’ in the economy [29]. Others have described financialisation as the methods and practices through which value is increasingly extracted from the ‘real economy’ (i.e., the section of the economy concerned with the production, trade and consumption or use of goods and services) into the ‘financial economy’ (i.e., the section of the economy that solely deals in transactions involving money and other financial assets) [30–32]. Despite financialisation being one of the defining features of modern food systems [33, 34], and contemporary capitalism more broadly [29–32], there has only been limited focus in the public health literature on the relationship between financialisation and the global rise of UPFs.
In this paper, we focus on one key aspect of financialisation that has been described as a potentially important shaper of population diets and food systems: the increasing prioritisation of the financial interests of shareholders and owners by the decision-makers of UPF corporations above other economic, health, social and ecological considerations [22, 35]. The norm underpinning this mode of corporate governance is often labelled ‘shareholder primacy’, referring to the belief or view that the sole purpose of the business corporation should be to maximise returns for its shareholders or private owners because this is the most rational and efficient way of achieving the broader social good [36]. While ‘shareholder primacy’ has emerged to dominate the theory and practice of corporate governance in the world economy, sector-specific analysis can help to determine the extent to which the norm has been operationalised by a particular sector, as well as expose some of its sector-specific implications [36, 37].
We argue that examining the extent to which ‘shareholder primacy’ influences the governance of UPF corporations is important for several reasons. To start with, this type of examination can help to scrutinise many of the responsibility and sustainability claims made by UPF corporations, many of which belong to broader discussions on ‘stakeholder capitalism’ championed by organisations such as the World Economic Forum and the Business Roundtable [38, 39]. Pertinent examples include claims such as ‘creating shared value’ in order to ‘enhance quality of life for everyone’ [40], supporting communities to build a ‘better shared future’ [41], and building sustainable economies [42]. There are growing concerns that these claims are an attempt by UPF corporations to position themselves as ‘part of the solution’ to the problems they perpetuate [43]. This positioning, in turn, seeks to legitimise corporate and industry self-regulation, as well as the participation of major UPF corporations in national and international governance arrangements ostensibly designed to address diet-related social and environmental harms [19].
An examination of the governance of UPF corporations also encourages analysis of the ways in which different types of investors influence the behaviour of these corporations, a topic that has received minimal analytical attention in the public health literature. While most investors typically strive to maximise their returns on the investments they make, their approaches and perspectives vary, as does their influence on corporate governance [44]. For instance, interest from so-called ‘responsible investors’ in improving population diets is reportedly building, often as part of broader environmental, social and governance (ESG) initiatives [45]. Responsible investors often try to influence corporate governance via several complementary mechanisms, including by filing or supporting shareholder proposals, i.e., a proposed recommendation or requirement that the corporation or its board of directors take a specific course of action that is put to vote at shareholder meetings [45].
At the same time, campaigns from investors seeking to maximise their returns in the short-term are common and widespread [44]. In particular, it has been noted that so-called hedge fund ‘activists’ have played a major role in reinforcing ‘shareholder primacy’, especially since the Global Financial Crisis [44]. One of the core investment strategies of hedge fund ‘activists’ involves purchasing a minority stake in a publicly listed corporation in order to influence the way in which it is governed [46]. Specifically, most hedge fund ‘activists’ seek to maximise shareholder returns in the short-term by pressuring corporate decision-makers to undertake large-scale cost-cutting practices (e.g., large job cuts) and to increase shareholder payouts [44]. Compared to responsible investors, hedge fund ‘activists’ often use a different set of strategies to directly influence corporate governance, such as by attaining representation on corporate boards, pursuing a proxy contest to elect new corporate board members, and publicly applying pressure on corporate decision-makers to meet their demands [46, 47].
Large asset management firms, such as BlackRock and Vanguard, are another important type of investor that warrant further public health attention. Research has shown that a relatively small number of asset management firms now hold a large proportion of shares across the entire corporate food system and, more broadly, the corporate economy [48, 49]. As such, they are conferred with substantial powers to shape corporate governance, including with respect to their outsized influence on the overall support that shareholder proposals receive [49]. While evidence suggests that many of the world’s largest asset management firms vote against proposals that seek corporate action on various social and environmental issues [50], the extent to which they oppose public health-related proposals that target major UPF corporations remains unclear.
Given the above considerations, this paper aimed to explore the degree to which UPF corporations have become ‘financialised’, focusing on the extent to which they have been prioritising the financial interests of their shareholders relative to other actors, as well as the role that various types of investors have played in influencing their governance. Specifically, the paper had three related objectives. First, to document and describe trends in the monetary value of shareholder wealth and income generated by UPF corporations relative to corporations active in other food and agricultural sectors. Second, to document and describe the extent to which the world’s major UPF corporations have been prioritising the short-term financial interests of their shareholders. Third, to explore some of the ways in which various types of investors – notably, responsible investors, hedge fund activists, and large asset managers – have influenced the governance of the world’s major UPF corporations. The findings were used to inform discussion on potential challenges and opportunities for advocates, researchers, and policy-makers seeking to address the global rise in the consumption of UPFs.
