- Kimberley Wilson, psychologist who worked at HM Prison Holloway (then Europe's largest women's prison), argues nutrition is as important for mental health as medication and therapy, shaped by watching poor diet leave prisoners less able to control their emotions.
- Randomised controlled trials in prisons showed broad-spectrum micronutrient supplementation (vitamins, minerals, omega-3) reduced violence by 30%, which Wilson calls the "starkest, clearest evidence" that the brain is a physical organ needing proper fuel.
- Wilson attributes psychiatry's neglect of diet to Cartesian mind-body dualism, describing the field's current approach as a "neck-up intervention" that treats the brain as separate from the body.
- Clinical data shows 1 gram per day of omega-3 (60% EPA) can reduce depression, with omega-3s acting as necessary precursors to inflammation's "off switch," according to Wilson.
- Wilson highlights that iron deficiency impairs serotonin production and is linked to mood disorders, noting that simply correcting anaemia can lift depressive symptoms without therapy.
- The World Health Organization identifies iodine deficiency in the perinatal period and early infancy as the leading cause of preventable brain damage worldwide, associated with low IQ.
- Wilson, now breastfeeding, takes a choline supplement because most prenatal vitamins lack sufficient choline, citing research that prenatal choline supplementation improves attention in children at age 7.
Why it matters: Wilson's framing puts empirical pressure on the medication-and-therapy default in psychiatry: the cited prison trials showed a 30% violence reduction from micronutrient supplementation alone, and her clinical example of iron deficiency masquerading as depression suggests basic nutritional screening could resolve cases that currently go to medication or years of therapy.
