Although it is clear that nutrition affects physical and metabolic functions in humans, the importance of nutrition in mental illness has often been overlooked. Following a report by Hibbeln (Lancet 351:1213, 1998) published in The Lancet, which suggested that depression rates and fish consumption were inversely correlated, the relationships between a variety of nutritional/epidemiological treatments and neuropsychiatric disorders have received increased attention. In particular, many studies have been conducted on the omega-3 fatty acid mechanism of action in pathophysiological aspects of various neuropsychiatric disorders. Furthermore, many clinical studies have also been conducted on the effects of omega-3 replacement therapy. Therefore, this article reports recent trends in, and perspectives on, the use of omega-3 fatty acids to treat the five psychiatric disorders: schizophrenia (a delusion of the psychotic zone), depression and other mood disorders, attention deficit hyperactivity disorder (a developmental disorder), post-traumatic stress disorder (psychological trauma after the disaster), and Alzheimer-type dementia.

尽管营养会影响人类的身体和代谢功能是显而易见的，但营养在精神疾病中的重要性却常常被忽视。在 Hibbeln (Lancet 351:1213, 1998) 发表在 The Lancet 上的报告表明抑郁率和鱼类消费呈负相关之后，各种营养/流行病学治疗与神经精神疾病之间的关系受到越来越多的关注。特别是，已经对 omega-3 脂肪酸在各种神经精神疾病的病理生理学方面的作用机制进行了许多研究。此外，还对 omega-3 替代疗法的效果进行了许多临床研究。因此，本文报告了最近的趋势和观点，
