Most people assume the wellness industry's rise was a response to a population that didn't know how to eat. The evidence suggests the opposite — that a generation who grew up without nutritional supervision learned an internal regulation that the people now selling apps, supplements, and identity-based diets are still trying to reverse-engineer.
Walk into any bookstore and the food section reads like a confession booth. Macros, fasting windows, gut protocols, anti-inflammatory plans, glucose monitors strapped to upper arms. Each one is a different way of outsourcing a decision that used to happen between a person and their stomach.
The cohort least likely to participate in any of it is the one that came of age in the 1970s.
The generation that wasn't watched
For anyone who grew up in that decade, breakfast was negotiable, lunch was whatever fit in the bag, and dinner happened when someone called them in from the street. Nobody tracked it. Nobody photographed it. Nobody asked whether the bread was sprouted.
The fridge was a small archive of leftovers, condiments, and one or two things on the edge of going off. A child opened it, made a decision, closed it. The decision was theirs, and the consequences — hunger, fullness, an upset stomach — were also theirs.
That sounds neglectful by today's parenting standards, but it was also, accidentally, the conditions under which appetite self-regulation develops most reliably.
What the research actually says about that
Children build the capacity to read their own hunger and fullness from infancy, integrating biological signals with cognitive control that lets them resist impulses and adjust later meals based on earlier ones. A summary of the field published by Nature describes how this self-regulation can be derailed when caregivers apply either restriction or pressure — both of which interrupt the child's own developing relationship with appetite.
The 1970s kitchen, for all its chaos, was unusually low on both. Nobody was pressuring children to clean their plate the way previous generations had. Nobody was restricting them the way later ones would. The food was just there, the child was just there, and the negotiation happened privately.
That privacy turns out to matter. Research from Aston University led by Professor Jacqueline Blissett has shown that parents' own eating styles powerfully shape how children respond to food, and that overt feeding strategies — the constant commentary, monitoring, and rule-setting that defines modern parenting around food — often work against the very behaviours they're trying to produce.
The counterargument worth taking seriously
The 1970s diet was plainly bad — Tang, margarine, processed cheese slices, sugary cereals marketed directly to children. The food itself was often industrial garbage dressed up in cheerful packaging.
And the long-term consequences of early exposure to that kind of food are real. A recent study from University College Cork, published in Nature Communications, found that early exposure to high-fat, high-sugar diets can produce lasting changes in the brain's appetite-regulating pathways — changes that persist even after the diet improves and body weight returns to normal. Dr Cristina Cuesta-Martí, the first author, noted that early dietary exposure may leave hidden long-term effects on feeding behaviour that aren't visible through weight alone.
So the food was often bad, but the relationship to eating — the psychological architecture around the act of putting food in your mouth — was built without surveillance.
The difference between food and the relationship to food
These are two different things, and modern wellness culture conflates them constantly.
A person can eat well and have a tortured relationship with eating. They can eat moderately and have a calm one. The wellness industry sells improvements to the first by quietly degrading the second, because anxiety is a far better customer than equanimity.
People who grew up unsupervised around food in the 1970s often arrive in middle age having upgraded the food itself — more vegetables, less processed stuff, the slow drift toward better choices that happens naturally when the body starts giving clearer feedback — without ever having developed the meta-layer of moral commentary that younger generations bring to every bite.
They eat dinner. They don't perform dinner.
What the absence of an app actually buys you
A pattern shows up in people who track everything. The app becomes the authority. The body becomes the data source. The decision moves from inside to outside.
This is the same pattern Psychology Today has documented in its coverage of diet culture's psychological hazards — the way restrictive frameworks leave people either obsessed with the foods they've banned or fearful of them, with weight regain in the years afterward that often leaves the dieter heavier than before they started.
The intuitive eating movement is the closest thing the wellness industry has produced to what 1970s kids accidentally learned: pay attention to what the body is telling you, eat when hungry, stop when full. But as other Psychology Today writing on the approach makes clear, intuitive eating is hard to practice once a person has spent twenty years overriding internal signals with external rules. The signals get quieter. The rules get louder. There's a process of relearning something that was already known.
The 1970s kid never had to relearn it because nobody intervened in the first place.
Who profits from the surveillance
The continuous glucose monitor market is projected to be worth tens of billions of dollars within a few years. The meal-tracking app market is already enormous. Supplement brands, meal-kit companies, gut-health protocols, hormone-balancing programmes — every one of them depends on a customer who believes their own body is not a reliable narrator.
This is a real economic structure built on selling certainty to anxious people, which scales better than selling food to hungry ones.
The generation that grew up drinking from the garden hose is, by sheer accident of timing, a poor target market for this. They already trust their hunger. They already know what fullness feels like. They already have a working internal compass that the industry would need to break before it could sell them a replacement.
The morality layer
The other thing missing from the 1970s table was moral framing. Food wasn't "clean" or "dirty." It wasn't "ethical" or "guilty." It wasn't a statement about who you were.
This is where the contrast with the present is sharpest. Younger generations have inherited a culture in which every meal is a small referendum on identity — values, politics, discipline, aesthetic. The cognitive load of eating has gone up dramatically.
That isn't all bad. Some of the most thoughtful shifts in adult eating come from a slow widening of the moral imagination — caring about animals, the climate, the workers, the systems. Those shifts are real and they matter.
But the morality layer becomes corrosive when it replaces the appetite layer instead of sitting alongside it. When a person can't tell whether they're hungry but can tell whether their meal is virtuous, something has gone wrong upstream.
The 1970s kid, now in their fifties or sixties, can often hold both. They'll eat the vegetable curry because it's good and because they're hungry. They'll eat the steak at the wedding because it's in front of them and they're not interested in making a scene. The choice doesn't require an internal trial.
The undivided attention thing
There's also the question of how the meal itself was conducted. Dinner happened at a table. The phone — singular, attached to the wall — didn't ring during it, or if it did, nobody answered. The television was usually off. The undivided attention of that era was the medium in which appetite signals had room to develop.
A child ate a thing. They noticed the thing. They stopped when the thing was finished or when they were finished, whichever came first. There was no scrolling to dull the feedback loop.
This matters because satiety signals are slow. They take fifteen, twenty minutes to register. Distraction blows past them. Anyone who has eaten an entire bag of crisps while watching a film knows the experience of finishing without noticing.
What this isn't an argument for
This argues for noticing that one specific thing — the unsupervised, unmoralised, unmonitored encounter between a child and the contents of the fridge — produced a psychological outcome that the wellness industry is now spending billions trying to recreate, and largely failing.
The lesson sitting in this data isn't that everyone should go back. It's that the next generation of parents could pick up something useful from the one before last: stop narrating the meal. Stop assigning it a moral weight. Stop building rules where attention would do the work better.
A child who is allowed to be hungry, and then allowed to eat, and then allowed to stop, is doing the most important nutritional work of their life. Everything after that — the kale, the protein, the omega-3s — is downstream of whether they still trust the signal in the first place.
The quiet competence of the unsupervised
What becomes apparent in conversation with people in their fifties and sixties who eat well without apparent effort is the absence of vocabulary. They don't have a word for what they're doing. They're not "intuitive eaters" because they never had to name it. They're not "mindful" because they've never read a book about mindfulness. They're just eating.
That fluency is hard to acquire later. It's much easier not to lose.
The fridge in 1976 was unimpressive. The relationship to it was the thing worth keeping.
