Anorexia nervosa has one of the highest mortality rates of all psychiatric illnesses. The severity and resistance to treatment of anorexia have led researchers to develop animal models to better understand the disorder's mechanisms, with activity based anorexia being the most prominent. This unique behavioral phenomenon provides critical insight into the interaction between restricted food intake and excessive physical activity.

The term pica derives from the Latin word for the magpie (*Pica pica*), a bird famous for its non-selective eating habits and penchant for gathering a variety of objects. This avian connection offers a curious historical insight into the naming of this compulsive feeding disorder.

According to the World Health Organization (WHO), over 280 million people suffer from depression globally, and emerging research suggests a potential link between this condition and nutritional status. A growing body of evidence indicates that low levels of vitamin D may increase the risk of depression, though the nature of this relationship remains complex.

Case studies have documented instances where severe Vitamin B12 deficiency has manifested as acute psychosis, presenting with symptoms like delusions and hallucinations, even in the absence of typical anemia. This demonstrates that specific nutritional deficiencies can cause psychosis and underscores the importance of nutritional health for brain function.

Emerging research indicates that diet can play a significant role in managing mental health, with poor nutrition potentially worsening psychosis symptoms. For individuals with this condition, understanding what foods should psychosis patients avoid is a crucial component of a comprehensive health strategy.

Case studies have documented instances where vitamin B12 deficiency was identified as the causative factor behind manic episodes, with symptoms resolving after supplementation. While not the sole cause, this highlights that a significant vitamin deficiency can cause mania or mimic its symptoms, underscoring the vital connection between nutrition and neuropsychiatric health.

Research has found vitamin D and folate deficiencies present from the earliest stages of first-episode psychosis, suggesting that understanding what are the nutritional deficiencies of psychosis is crucial for improving patient outcomes. This article delves into the specific nutrient deficits linked to psychotic disorders and their impact on mental and physical well-being.
