In this post, Nicos Kefalas (a PhD student with the Balance project) discusses his doctoral research into healthy eating and supplementation. Here he considers why self-help books about diet became so popular in the post-war period, and examines the ways in which this literature deployed linguistic devices to construct readers as “empowered” agents of healthy-lifestyles.

In recent years, it seems that not a day passes by without public debate about healthy eating and supplements. Thousands of magazines, newspapers, websites, YouTube videos and blogs are dedicated to issues revolving around food, diet, exercise, supplementation and health. Popular discussants of healthy diets even make use of data from randomized-control trials (RCTs) and population studies, metastudies and large trials, and translate such knowledge into easily digestible graphics on various foods and supplements to demonstrate whether or not they are truly good for overall good health. (Or to weed out products that could be considered as ‘snake oils’).[1]

 

My PhD examines the historical emergence and development of healthy eating, dietary advice and supplements to provide a better understanding of when, how, why and by whom ‘Healthmania’ was promoted. [2] ‘Healthmania’ is the fascination of various institutions of the West with healthy diets, foods and supplements, and the concomitant production of advice and products to help individuals attain better lifestyles, both independently and collectively. From the 1950s onwards, self-help literature, lifestyle magazines, newspapers, advertisers, science and the state accepted and promoted certain foods, diets and supplements for a number of reasons. Building upon a widespread valorisation of science on the one hand, and fascination of the media and public with slim bodies and healthy lifestyles on another, leading scientists, public figures and state bodies were all motivated by a mixture of personal ambition and broader political aims to promote healthy eating and supplementation.

 

Following historical work on Galenic medicine, food and health that has centred on early-modern herbals, manuals and cookery books, I am currently examining English language self-help books published between 1950-2000 which concentrate on nutrition, diets, food and health.

 

‘HEALTHMANIA’ IN SELF-HELP BOOKS’

Self-help authors made individual agency central to their efforts to popularise ‘optimal’ and ‘ideal’ diets. It is clear that the language and advice in self-help books emphasize and promote the notion that readers have the power to manage their own health and a moral obligation to do so. The books heavily imply that the proactive, educated, well-read and well-informed individual can promote their own good health. The readers are initiated into a self-narrative in which they do not need or want the help of doctors and expensive or ineffective treatments. This newfound agency over their own health is reinforced by the growth of capitalism to provide the foods and supplements necessary to sustain a mentality of ‘buying a better body’. Indeed, not only does the self-help literature direct its readers to the nearest health food stores, pharmacies and juice bars, but it also urges readers to consume specific foods (often exotic fruit), drinks and supplements. Some authors of self-help guides even take a further step. For example, Dr Atkins urges his readers to monitor their progress using a home urine-chemistry kit, encouraging the purchase of sophisticated surveillance technology, alongside expensive dietary consumables and further literature.

One of the reasons behind the popularity of the self-help industry lies in the fact that it stood out from mainstream science and advice for better health, which often consisted of the mantra to ‘eat less, exercise more’. By contrast, whilst self-help books sought to empower readers to make positive changes in the present and future, self-help books nonetheless removed the blame for ill-health and obesity from their readers and instead attributed responsibility for past failures to the food industry, ‘modern foods’, fast foods, mainstream science, and modern lifestyles. Each reader is thus given the chance to feel like a revolutionary and an ‘enlightened’ consumer. This narrative was facilitated through the consistent use of motivational language, tone, expressions and symbolism. Taking Atkins’ book as an example once more, one can see how phraseology and capitalisation of sentences urged his readers to stop being bystanders to the damage done to their bodies by modern foods (namely carbohydrates in this case) and start defending their health. Such phrases were ‘A REVOLUTION IN OUR DIET THINKING IS LONG OVERDUE’ and ‘WE ARE THE VICTIMS OF CARBOHYDRATE POISONING’.[3]

 

People turned to self-help books because they addressed contemporary anxieties of the everyday individual. The fear of hunger, for instance, is explicitly addressed by the genre as a whole. These authors knew that people fear hunger, because when they are hungry they lose their control of their bodies, and compromise their diets with filling – though not necessarily healthy – foods. In the short-term, authors reassured readers, this was not necessarily an issue. As Robert Haas advised his readers: ‘There is no point in worrying about cheating occasionally’. He noted, however, that such infidelities to his rules were only acceptable if ‘you stick to the Peak Performance Programme in the long run’.[4]

 

Yet, alongside questions of deprivation, self-help authors had another, seemingly paradoxical, problem to think about, – luxury and efficiency. No one wants to start a boring diet that does not bring the desired results fast enough.  Produced at a time when instant gratification of nearly all desires, cravings and wants can be quite simply achieved, self-help books had to portray eating healthily as an easy process coming from filling, varied, tasty and luxurious foods. For example, Atkins argued that people could lose weight on: ‘Bacon and eggs for breakfast, on heavy cream in their coffee, on mayonnaise on their salads, butter sauce on their lobster; on spareribs, roast duck, on pastrami; on my special cheesecake for dessert’.

 

These and many more themes in the self-help genre play a big part in the popularisation of science and the growth of ‘Healthmania’. The readers of these books are given the knowledge to become active agents of their own health. Change towards better health is elevated to an individualistic and stoic process by which the readers refused to be ill, overweight or obese. The process of becoming healthier offered by the self-help genre is easier with less hunger and more ‘exotic’ and luxurious foods than the average diet recommended by the state and doctors. The advice in these books offers readers a way to avoid the dreaded visits to doctors’ practices, and thus on the surface at least, serves in part to undermine the authority of orthodox medicine. However, even though these books seem to have been against modern scientific theories/practices, self-help authors were using contemporary scientific ideas. These authors offered a self-criticism of the various food and health-related professions they wrote from.  They did so by using widely accepted scientific tools and perspectives to criticise orthodox medicine and dietetics from a marginal perspective.  Indeed self-help books promoted their advice by using the same tools and analytics (macronutrients, micronutrients, calories, specific foods and supplements, the culture of quantification, and often their authors underwent the same training as their ‘mainstream’ counterparts). By following the advice offered by these books, the readers break out of the complacency to ill-health imposed on them by ‘modernity’ and became part of a reactionary kinship. In these works, health itself became a rational, measurable and quantifiable endeavour. More significantly, though, it became a commodity, leading to the explosion of the supplement industry and ‘Healthmania’ in general.

Life Begins at 40

Mark Jackson

It became commonplace during the twentieth century to regard the age of forty (or more recently fifty) as a tipping point in the life cycle, a moment when many people could begin to shed the financial, domestic, parental and occupational worries of youth and middle age and look forward to a more serene and comfortable period of their lives.  The belief that life after forty might present opportunities for, rather than obstacles to, happiness was given legitimacy by a post-Second World War culture that considered increased consumption and economic growth, at least in the West, as the primary route to self-realisation and emotional fulfilment.  Made possible partly by increased life expectancy, the crisis of middle age was recast as an epiphany, a moment of temporary imbalance that was necessary if age-related cognitive and economic decline were to be effectively reversed and individuals inspired to achieve the highest levels of personal satisfaction and well-being.

The origins of late-twentieth century convictions that life begins at forty were, however, less emancipatory than we might imagine.  Rather, they were rooted in reactionary attempts to preserve political stability, economic productivity and family unity.  Four days after the American army entered the First World War in 1917, Mrs Theodore Parsons was interviewed by The Pittsburgh Press, a local daily newspaper.  The author of manuals that encouraged children and young women in particular to embrace physical education as a means of cultivating intellectual advancement, health and beauty, Parsons tied her educational creed to the urgent need for women to train themselves for the `duties that war time may bring’.  `The mothers of a nation’, she argued, `are its supreme asset and as civilization advances it will be as natural for a nation to maintain its mothers as it is to-day to support its army and navy.’  Parsons’ conviction that women, as well as men, were critical to the war effort was not restricted to the young, but extended to the middle aged and elderly.

‘Most old age is premature, and attention to diet and exercise would enable men and women to live a great deal longer than they do to-day.  The best part of a woman’s life begins at forty.’ [1]

Parsons’ words constitute the first modern reference to forty as a transitional age in the fight for freedom and happiness.  But her aim was only incidentally the promotion of individual well-being.  More important for Parsons and her contemporaries were the social and military benefits of healthy ageing.  The notion that life, rather than death, began at forty was taken up most prominently by Walter B. Pitkin, Professor in Journalism at Columbia University.  Pitkin situated his self-help dogma in the context of an emergent American dream.  Science and technology had increased life expectancy, reduced the need for heavy labour in the home and workplace, and made leisure a genuine possibility for many Americans. ‘At forty’, he promised in 1932, `you will be wiser and happier than at thirty.  At fifty you will be clearer, steadier, and surer than at forty.’ [2]  Of course, the collective benefits of enhanced individual health and wealth were evident: greater consumption of services and goods would increase productivity and boost the American economy, fuelling further technological development and economic growth in a cycle of expansion.  Couched in capitalist terms, here perhaps were the seeds of the narcissistic veneration of the midlife transition that triumphed after the war.

In Britain, inter-war attention to the change of life in men and women around the age of forty adopted a different, but no less reactionary, complexion.  During the 1930s, Marie Stopes addressed the effects of ageing on married couples.  In Enduring Passion, first published in 1928, and Change of Life in Men and Women, published eight years later, Stopes questioned the inevitable decline in sexual health and satisfaction that appeared to beset previously passionate couples.  The notion of a crisis around menopause (or the equivalent decline in male virility), she argued, had been exaggerated by popular medical writers.  By preparing more effectively for the challenges generated by the unfolding stages of life, it was possible to prevent what many people regarded as the inevitable conversion of ‘happy lovers’ into ‘drabby tolerant married couples’. [3]  Stopes’ formula for surviving the crisis of middle age became one of the foundational principles of the marriage guidance moment, a development that originated in the late 1930s but subsequently emerged as one of the key features of a post-war settlement intended to restore the stability of the nuclear family.

It did not take long after the Second World War for these conservative dreams of social coherence and domestic stability to be destabilised, but covertly reinforced, by the rampant individualism of the marketplace. ‘Forty-phobia’ became an advertising slogan for companies selling nerve tonics that promised to help patients ‘feel younger as they grow older’. [4]  For men in particular, the purchase of household goods, cars, holidays and suburban houses was promoted as a means of blunting the frustrations created by the contrast between the excitement of conflict and the boredom of corporate and domestic life, a phenomenon neatly captured in the post-war fiction of Sloan Wilson and Joseph Heller. [5]  Self-fulfilment and its spiritual benefits became the mantra of popular advice books aimed at the disaffected, but affluent, middle classes struggling to redefine and relocate themselves in a changing world.

One of the fruits of this process was the creation of a novel expression of self-discovery: the midlife crisis.  Coined in 1965 by the Canadian psychoanalyst and social theorist Elliott Jaques to describe psychodynamic collapse triggered by fear of impending death, the term rapidly came to define midlife madness, a powerful tool for both explaining and legitimating the search for personal fulfilment during the middle years. [6]  The cost in terms of other people’s happiness was regarded by many as less important than the self-realisation, emotional emancipation and spiritual awakening that the crisis supposedly made possible.  But `la crise de la quarantaine’, as it became known in France, was not embraced as a means of enabling healthy ageing in women, as Parsons had anticipated, or as a pathway to a more contented and durable marriage, as Stopes had hoped.  Shaped by late twentieth-century obsessions with the autonomous individual and the gospel of consumption, the notion that life can begin again at forty has been used to reinvigorate a Western capitalist economy that can only be sustained by prolonging productivity and encouraging spending across the whole life course.

How not to kill your argument: looking after men without scapegoating women

Fred Cooper

On July 2nd 2016, the Guardian online newspaper published an anonymous open letter, written by a husband to the “wife who won’t get a job while I work myself to death.” Subtitled “the letter you always wanted to write”, it documented the sense of betrayal felt by a successful lawyer who had come to realise that the woman he once thought of as loyal and kind was “OK with my working myself to death at a high-stress career that I increasingly hate, as long as [she doesn’t] have to return to the workforce.” His wife, he explained, occupied her time with volunteering and leisure while his health deteriorated, he aged rapidly and prematurely, and he felt increasingly “used and alone.” Setting out his position in egalitarian terms, he emphasised his need for real partnership in marriage, and cited the example she was setting to their daughter, who he wanted to be “never as dependent on a man as you are on me.”

The appropriated language of equality barely masked a deep misogyny, a profound anger at the high-octane demands of modern employment misdirected away from workplace culture and the cult of productivity and folded into, in Elaine Showalter’s words, the “fiction that women push the buttons and call the shots.” The wife and her friends were caricatured as self-centred, happy to gripe but not to help: “You all complain about various financial pressures, but never once consider, at least audibly, that you could alleviate the stress on both your budgets and your burnt-out husbands by earning some money yourselves.”

Post-war concerns about the role of women in activating or exacerbating men’s executive stress, here, were re-imagined for a cultural setting in which housewives rather than working mothers were anachronistic, subversive, and dangerous. The anonymous letter bore a striking resemblance to the popular medical writing of a 1960s author and practitioner, Kenneth C. Hutchin, in all but the precise nature of the advice. Each addressed women directly, whether through the device of the disgruntled husband or that of the fatherly doctor. An expert on the illnesses of businessmen, hypertension, and heart disease, Hutchin published a book in 1962 entitled How Not to Kill Your Husband, an expanded version of a 1960 article in Family Doctor, ‘How to keep your husband alive.’

Underneath an illustration of a woman crouched behind her husband’s armchair with a revolver and a bottle of poison, “How to keep your husband alive” explained that, while “the number of women who set out to kill their husbands is surprisingly small, a great many wives could not polish them off better if they tried.” Women, Hutchin argued, rarely realised how delicate their husbands were. Making use of an infant language of risk, he depicted men in their forties and fifties with non-manual, highly responsible jobs as a fragile population, vulnerable to heart attack or stroke. In this instance, wives were not letting their husbands die by omission, but could actively provoke a fatal rupture in the soft, overwrought, morbid bodies fed by high-starch diets and enervated by sedentary labour.

For Hutchin, male health was compromised by two of the central features of post-war companionate marriage; a growing tendency for men to engage in household tasks, and a softened system of patriarchal authority in marital relationships. He illustrated his first concern with two short vignettes, each demonstrating the hidden threat of domestic contribution. In both instances, women pestered their husbands into working when they should be relaxing, with one man becoming “unable to move because of a vice-like pain in his chest” and the other undergoing coronary thrombosis later in the evening. “Dear ladies”, Hutchin concluded, “do stop finding little jobs for your husbands to do.” Work around the home should be “decently accomplished during the day”, whether by tradesmen or by the wife herself, “not waiting there, a reproach and a menace to the tired master of the house.”

Erosion of male leisure went hand in hand with erosion of male authority. Victorian wives who submitted to the “law and wisdom” of their husband’s orders were “probably happier than the modern wife” who distrusted him and disputed his word. Anger and frustration, Hutchin argued, “are dangerous emotions for tired middle-aged men with a poor coronary circulation. The wife who constantly annoys her husband does so at her own risk and his.”

As Margaret Mead observed in 1954, the implication of women’s behaviour in the illnesses of others frequently contained a “subtle form of antifeminism.” Hutchin’s demand for more support and deference in the home and the anonymous husband’s plea for financial contribution and independence indicate a troubling continuity in the identification and criticism of “pathological” female behaviour, a shared willingness to point the finger at women which destabilises the progress implied by the differences between the two critiques.

Feminists from the second half of the twentieth century onwards have made convincing cases for the transformation of identity and experience through work, but these arguments have been at their best when they put women’s needs in centre stage. The importance of feminism as a cultural and political force is sadly overlooked in present debates about preventive medicine, particularly psychiatry; we are far more likely to connect distress and disorder to biological processes than to interrogate the entrenched, systematic, structural ways in which women are driven or drawn into illness. At the same time, we are falling into ways of speaking about men’s distress which demonise and denigrate women, reducing the complexity of their feelings and actions to an imagined impact on male health and male self. There are nuanced and sensitive explorations of, for example, men’s depression, alcoholism, and suicide – look no further than Ali Haggett’s recent research – which demonstrate that these arguments can be had, persuasively and intelligently, without negating the all-too-fragile gains made in public discourses surrounding women. Anonymous husband, I hope you’ll try.

The Costs of Balance? Diet and Regulation in Twentieth Century Diabetes Care

For the past few months, I have been working on an article about dietary management and patienthood in twentieth-century diabetes care. One key theme that has reoccurred throughout this research might be summed up by the question: “balance at what cost?” This is a question that patients and practitioners have had to ask consistently (if implicitly) since the 1920s, and I believe its history may have something to contribute to present discussions.

Balance: A Bit of Everything or Denial of Some Things?

Whether in popular culture or medical discourse, achieving and maintaining balance has frequently been discussed in overwhelmingly positive terms.

For patients with diabetes, medical advice for much of the twentieth and twenty-first centuries has been that metabolic balance is potentially life-saving.[i] That is, glycaemic control has been seen as the best safeguard against a range of short-term problems, as well as the means to prevent the onset of – or reduce the likelihood of developing – devastating long-term complications.

Yet, whilst we might associate balance with phrases like “all things in moderation”, balance in diabetes care has historically been construed in terms of restriction and regulation. Dietary management, that is, has often entailed either removing, carefully controlling, or substantially increasing the intake of certain foodstuffs. Amongst other things, hyper-vigilance and the inability to have a little of everything have been two of the costs associated with balance for individuals (and often their familial and social relations).

Changing Dietary Regulations

This is not to say that patterns of dietary prescription have remained static over time, especially for patients who required insulin. (Weight reduction through calorie control remained a constant imperative for overweight patients not using insulin.)

For instance, in the first few decades of the twentieth century, doctors discussed metabolic balance in relation to a careful restriction of carbohydrates. In fact, in some cases this even extended to banning certain foodstuffs. Lists of “forbidden foods” were often included on dietary sheets, and one doctor even declared that he had a “feeling that it is better for the patient to forget about the taste of bread altogether than be exposed to the temptation when he takes a fraction.”[ii]

These strictures altered considerably in following decades. During the 1930s and 1940s, doctors began to prescribe higher carbohydrate allowances, and in the following decades they dropped careful fat and protein regulation to help reflect more “normal” dietary patterns. After two decades worth of debate about the role of “free diets” in care, higher fibre intakes became a feature of discussions in the 1970s and 1980s, following the testing of theories designed in colonial sites of research. By century’s end, programmes for “normalisation” slowly began to move to the fore, resulting in strategies like DAFNE.[iii] Gradually, “forbidden” foods became controlled foods.

Calculating Costs

Regardless of these moving goal posts, patients and their families rarely adhered fully with their medical instructions. For some, this was simply a case of not being able to afford diets. The financial cost of diabetes diets regularly ran considerably higher than average expenditure on non-medical diets.

For other patients, the logistics of careful management were just as much of a barrier. Surveillance – with its constant vigilance, measurement, inscription and assessment – required more than considerable energy. It also demanded action, and access to a whole material culture. (Pens, records, dietary sheets, scales, jugs, and urine testing equipment.) The time and materials required were rarely accessible in the workplace, and regulating an individual’s diet often had unacceptable consequences for spouses, families, employers, and friends. Indeed, for patients regulating their diet in public, one result might be to mark them out, risking negative comments, social awkwardness and anxieties, as well as problems at social events, such as meals or celebrations. Under such circumstances, patients were either physically unable to manage their diets, pressured into certain actions, or encouraged to weigh their priorities and find (quite rationally) that other relationships and activities were worth the possible costs.

This also to say nothing about the extent to which prescriptions were adapted for cultural, class-based, or dietary preferences. Or, indeed, to discuss palatability. As one patient (who was also a doctor) challenged readers in The Lancet: “you try getting through 3-4oz butter with 1oz of bread to spread it on!”[iv]

Patients and Costing Balance

What I have taken away from this research is that many of the costs that follow the pursuit of balance are deeply embedded into social and cultural life, and can’t all be altered by educational, motivational, or bureaucratic programmes and imperatives.[v] The challenges of the past, in other words, are not dead, but are in many respects still with us.

In fact, we might ask whether there is a broader discussion to be had, one concerning the values attached to balance, and the extent to which reasons for patients not following advice should be conceived as “problems”. In many respects, this has been the starting point for many strategies designed to investigate and improve “compliance” and “adherence” in the past four decades.[vi]

To be sure, I believe that patient education is vital. Equally, co-operation between health care teams, patients and families is often integral to effective care, just as glycaemic control can be protective of long-term health. (Though not a guarantee.)

Nonetheless, at some point it will be necessary to consider the limits to these strategies, and – to a certain degree – the desirability of consistent attempts to problematize and alter behaviour. For those of us without the condition, it is also worth thinking clearly about the costs involved in management before rushing to moral judgement. One patient (again a practitioner) perhaps put it best when writing just after the Second World War:

“Each meal should be an elegant satisfaction of appetite rather than a problem in arithmetic and a trial of self-abnegation”.[vii]

Things have changed significantly since 1946, but daily challenges to patients are still considerable, and the mental, emotional and physical affects of management remain.
