Diet restriction of rodents during adult life is known to cause an increased life span. It has been hypothesised that this increase may be related to effects on the anti-oxidant defence systems. However, it has been suggested that undernutrition during the gestation and pre-weaning may reduce their life span as it is known to have other deleterious effects on a rodent's growth and development.
Converging evidence suggests that a neurodevelopmental disruption plays a role in the vulnerability to schizophrenia. The authors review evidence supporting in utero exposure to nutritional deficiency as a determinant of schizophrenia. We first describe studies demonstrating that early gestational exposure to the Dutch Hunger Winter of 1944--1945 and to a severe famine in China are each associated with an increased risk of schizophrenia in offspring.
Perturbations in the levels of serotonin expression have a significant impact on behavior and have been implicated in the pathogenesis of several neuropsychiatric disorders including anxiety, mood and appetite. Fetal programming is a risk factor for the development of metabolic diseases during adulthood. Moreover, previous studies have shown that serotonin (5‑HT), dopamine and leptin are important in energy balance.
