Deficiencies in Vitamins and Disease-Specific Diets Impacting Mental Health

Optimal nutrition is critical in maintaining bodily functions and preventing dysfunctions from various internal or external factors. Scientific evidence has established a strong link between dietary choices, brain health, and the risk of psychiatric disorders. Diet and nutrition significantly influence physical fitness, body composition, mood, and mental well-being through mechanisms such as reducing inflammation, acting as antioxidants, promoting neurogenesis, modifying the microbiome, and affecting the immune system. The chapter highlights the vital connection between vitamins and brain function metabolism and psychiatric conditions. Deficiencies in these essential nutrients have been associated with cognitive impairment, depression, psychosis, and other neuropsychiatric conditions. Additionally, disease-specific diets have been instrumental in mental health management. For instance, the few-foods approach benefits conditions like attention-deficit/hyperactivity disorder. Moreover, the chapter emphasizes how a well-rounded diet supplemented with vitamins positively impacts mental health, cognitive performance, and neuroinflammation. It overviews water-soluble and fat-soluble vitamins, their roles in brain metabolism, psychiatric conditions, and their impact on mental health. It discusses disease-specific diets’ effects on mental well-being. It emphasizes the need for further research to comprehend the full scope of nutritional interventions in mental health improvement and outcomes. Conclusively, the chapter underscores the necessity of recognizing and addressing vitamin deficiencies, along with exploring the impact of disease-specific diets to optimize mental health. It provides valuable insights for clinicians to recognize and manage nutritional deficiencies in mental health conditions, paving the way for enhanced treatment strategies.
