In this meta-analysis, researchers provide an overview of the emerging field of nutrition psychiatry. They also synthesize current findings on diet and nutrition and their impact on mood and mental health.

1. Nutrition is crucial in addressing the burden of mental disorders, and its importance should be recognized in psychiatry.
2. Unhealthy dietary patterns are linked to a higher prevalence of mental health issues, while healthy dietary patterns reduce the risk of depression and suicide.
3. Nutrient-based supplements, such as omega-3 fatty acids, SAMe, NAC, zinc, B vitamins, and vitamin D, show potential in managing mental disorders.
4. Future research should focus on identifying the impact of overall diet and specific nutritional elements on mental health and the efficacy of nutrient supplements.
5. Governments should take action to improve food quality, promote healthier dietary practices, and educate the public and clinicians about the role of nutrition in mental health.
