Nutrition Science: Orthorexia

When Eating Well Becomes Something Else Entirely

The pursuit of a perfectly healthy diet can quietly become one of the least healthy things a person does.

The Idea

Orthorexia nervosa — the term coined by physician Steven Bratman in 1997 — sits in an uncomfortable grey zone in nutrition science and psychology. Unlike anorexia or bulimia, it isn't primarily about weight or body image. It's about purity. The person affected isn't trying to be thin; they're trying to be clean, optimal, untainted. The obsession is with the quality of food rather than the quantity, which makes it both harder to recognise and surprisingly easy to admire from the outside. What makes orthorexia genuinely tricky is that many of its early behaviours look like health consciousness done right. Reading ingredient labels, cutting out ultra-processed food, learning about nutrient density — these are reasonable, even laudable moves. The shift happens gradually, when the rules begin to serve anxiety rather than health. Meals become a source of dread rather than nourishment. Social eating feels contaminated by imperfect choices. The diet shrinks, not necessarily in calories, but in flexibility, spontaneity, and joy. Bratman himself acknowledged the strange bind: he had coined the term partly to describe his own experience, having spent years on a farm eating only what he considered pure food, only to realise the practice had made him rigid, isolated, and paradoxically less well. The irony he captured is worth sitting with — that a fixation on physical health can erode mental, social, and emotional health in ways that are measurably harmful, even as the person maintains they have never felt more in control.

In the World

In 2015, Australian wellness blogger Jordan Younger — known online as The Blonde Vegan, with hundreds of thousands of followers — publicly announced she was no longer vegan. The response was fierce. Hate mail arrived immediately. But what Younger described in the aftermath was a textbook account of orthorexia: a diet that had started as an ethical and health-conscious choice and had gradually contracted into something that consumed her thoughts entirely. At the height of it, she was eating a tiny range of raw, plant-based foods, experiencing hair loss and hormonal disruption, and spending hours each day planning what she would and wouldn't eat. She felt virtuous — which is the particular quality that distinguishes orthorexia from many other disordered eating patterns. There was no shame in the restricting, only a growing sense of moral righteousness around food choices. When she finally began eating more broadly again — including, eventually, animal protein — she described not just physical recovery but a kind of psychological relief she hadn't realised she needed. The food she'd been eating was, by many metrics, nutritionally sound. The relationship she'd developed with it was not. Younger went on to write a memoir and speak openly about the experience, bringing wider public attention to a condition that, at the time, wasn't even formally recognised in psychiatric diagnostic manuals. It still doesn't appear in the DSM-5, which is itself a revealing detail about how slowly institutions catch up to lived experience.

Why It Matters

Most of us will never develop orthorexia. But the pattern it exaggerates — using dietary control as a proxy for managing anxiety, finding identity in what we refuse to eat, treating food as a moral ledger — exists on a spectrum, and many people sit closer to that end than they realise. The wellness industry has a particular talent for making rigidity look like discipline, and anxiety look like commitment. When a food rule starts to feel non-negotiable even in contexts where it causes real friction — turning down a meal cooked by someone you love, feeling distress at an unplanned lunch — that's worth noticing. Nutrition science is also genuinely uncertain, constantly revising its positions on fat, carbohydrates, red meat, dairy, and dozens of other things. A healthy relationship with food probably has to include some tolerance for that uncertainty — some capacity to eat imperfectly and feel fine about it. The question isn't just what you're eating, but what eating is doing to your relationship with the rest of your life.

A Question to Ponder

Is there a food rule you follow that you'd feel genuine distress — not just mild inconvenience — about breaking, and what is that distress actually protecting you from?
