Nutrition and mental health

Mental health has become a major public health issue and a matter of economic and social concern across the EU. A healthy dietary pattern can positively influence mental health and well-being through anti-inflammatory, antioxidant, neurogenetic, microbiome- and immune-modifying mechanisms, as well as through epigenetic modifications. Good nutritional status is essential to maintain normal body function and prevent or mitigate dysfunctions caused by internal or external factors. Alterations in the microbiome can also impact neurodegenerative disorders, as it is linked to various mental illnesses such as depression, bipolar disorders, and schizophrenia. The proposed project aims to provide a comprehensive European overview of the impacts of unhealthy diets on mental health in children, adults, and the elderly under different social and economic contexts. Project outcomes will provide tangible data on mechanisms explaining the effects of food groups, beverages, macro- and micronutrients on mental health disorders and disease progression. Standardized and validated metrics will be developed to analyze the role of the gut microbiome. Furthermore, knowledge gaps will be addressed, and recommendations will be formulated for nutrition professionals to improve dietary guidance for individuals with mental health disorders, thereby ensuring better health and longevity. By implementing targeted measures for the prevention and treatment of mental health disorders through balanced nutrition and developing specific communication strategies, the project will make a significant contribution to the European health strategy. Recommendations will focus on optimizing the intake of macro- and micronutrients in line with international health policies to improve mental health outcomes, particularly in vulnerable populations.
