Vegetarian Diets and Teen Eating Disorders: GAPS Context

The GAPS eating-disorders chapter describes a pattern Campbell-McBride saw in her practice: many young people with an eating disorder had previously followed vegetarian or vegan diets. Her explanation concerns increasing restriction and the nutrients removed. Hanna’s own history makes the distinction especially clear because the book says she was doing well while she still ate eggs, full-fat dairy and peanut butter.^[1]

The Diet Changes in Hanna’s History

At thirteen, Hanna stopped eating meat. The chapter describes a diet heavy in cereal, pasta, rice, bread and potatoes, but she continued eggs, full-fat dairy and peanut butter and did not avoid fat. The source says she was doing well during that period.^[1]

The later change came around sixteen. Under pressure from dance school to lose weight, she became vegan and removed foods containing fat. Illness, antibiotic treatment and further restriction followed in the chronology. Those details belong together. Her case does not describe an immediate decline the moment she first became vegetarian. The full Hanna case follows the later history.

The Author’s Clinical Pattern and Explanation

Campbell-McBride describes previous vegetarian or vegan eating in a large proportion of the eating-disorder histories she saw. She also states her personal professional view that the trend toward vegetarian and vegan eating is a main cause of psychiatric illness among young people. That is the author’s clinical interpretation; the passage does not provide a controlled comparison, a percentage for this exact pattern or a finding that every vegetarian teenager develops an eating disorder.^[1]

Her proposed sequence emphasizes an unbalanced diet, shortages of protein, zinc, fats, fat-soluble vitamins, B vitamins and magnesium, then impaired immunity, infections, antibiotic exposure and changes in gut flora. The nutrient guide explains those parts without turning a food label into a deficiency test.

What Animal-Food Removal Means in This Discussion

The older chapter argues that animal foods supply the most suitable protein and fat for a growing body. It names meat, fish, eggs and dairy as important sources and gives red meat particular attention for zinc. In that account, progressively removing these foods can narrow the supply of nutrients needed for growth and body functions.^[1]

The relevant question is the actual food pattern. “Vegetarian” can describe very different menus, and Hanna’s earlier eggs-and-dairy stage is different from her later animal-food-free, fat-free restriction. Keep the foods and the change in intake visible rather than assuming the label explains the whole history.

How the 2020 Book Distinguishes the Patterns

In its general vegetarianism discussion, Gut and Physiology Syndrome says long-term vegetarian eating can include animal foods such as eggs and full-fat dairy, natural food and substantial fermented food. It separately criticizes fully plant-only regimens, processed-food-heavy vegetarian eating and low-fat vegetarianism.^[2]

The same chapter then discusses the additional demands of GAPS recovery. It emphasizes animal foods for rebuilding and says vegetarianism is not suitable for that group, while directing people who need a higher plant proportion toward More-Plant GAPS. More-Plant still includes animal foods; the general vegetarian discussion does not create a separately named “Vegetarian GAPS” protocol.^[2]

The vegetarian-eating guide reads those passages together. The low-fat vegetarian guide explains the separate low-fat concern. Neither should be used to turn Hanna’s individual history into a rule about every family.

Restriction and Ordinary Food Preference Are Different

The case includes pressure to lose weight, increasing dietary restriction, continued efforts to lose weight and later diagnosed illness. Those are more specific facts than simply disliking meat or choosing a vegetarian meal. The chapter’s broader pattern cannot establish a diagnosis from one preference.

For a useful history, write down what changed and when: which foods stopped being eaten, what remained available, whether the amount or variety narrowed, and what symptoms or treatment followed. You can describe those changes without arguing about a label at every meal.

Questions About the Vegetarian Pattern

Does the Book Say Hanna Was Ill at Thirteen?

No. It describes her as doing well while she still ate eggs, full-fat dairy and peanut butter. The vegan, fat-free change came later.^[1]

Is More-Plant GAPS an Animal-Food-Free Plan?

No. The 2020 book’s approach changes the plant-to-animal-food balance. It does not remove all animal foods or rename the restrictive sequence in Hanna’s case.^[2]
