Key Points Regarding the Connection Between Nutrition and Mental Health

TopicKey pointsReferences
NeurotransmittersAmino acids from proteins, vitamins, and minerals are essential for synthesizing and regulating neurotransmitters (eg, serotonin, dopamine, norepinephrine).Briguglio et al, 201865
Nutrient deficiencies can disrupt neurotransmitter balance and contribute to the development or exacerbation of mental health disorders.
Antioxidants (eg, vitamins C, E, phytonutrients) protect against oxidative stress, crucial for the brain vulnerable to oxidative damage.Calderón‐Ospina and Nava‐Mesa, 202036; Olubukola Sinbad et al, 201986
Omega-3 fatty acids (eg, eicosapentaenoic acid and docosahexaenoic acid) possess anti-inflammatory properties, which potentially can alleviatie symptoms of mood disorders.Dighriri et al, 202263; Grosso et al, 201428; Keller, 200229; Lange, 202039
Diet influences the gut-brain axis, influencing the gut microbiome, which, in turn, can affect systemic inflammation, mood, and behavior.Bear et al, 2020100; Clapp et al, 2017101; Kumar et al, 202357
Inflammation and oxidative stressChronic inflammation and oxidative stress contribute to the development and progression of mental disorders.Ouabbou et al, 2020103; Salim, 2014104
Western diet high in processed foods and unhealthy fats promotes inflammation and oxidative stress, negatively affecting brain function and mental health.Christ et al, 2019108
Diets rich in fruits, vegetables, whole grains, and healthy fats (eg, Mediterranean diet) have anti-inflammatory and antioxidant properties that potentially reduce the risk of mental disorders.Tsigalou et al, 2020109
Gut microbiota and neuroplasticityThe gut-brain axis, a bidirectional communication system, is influenced by nutritional factors, such as dietary fiber and prebiotics.Cryan and Dinan, 2012111
Gut microbiota composition and diversity influence brain function, neuroplasticity, and mental health.Holscher, 2017112
Imbalances in the gut microbiota, often linked to poor dietary choices, may contribute to the development of mental disorders.Bear et al, 2020100
Dietary interventions and probiotics can promote a healthy gut-brain axis and support mental well-being.Clapp et al, 2017101; Bear et al, 2020100; Kumar et al, 202357
Overall summaryNutrition influences mental health through neurotransmitter synthesis, inflammation and oxidative stress modulation, and the gut-brain axis.
Adopting a balanced and nutrient-rich diet is crucial for mental health promotion and treatment.
Ongoing research is needed to understand the complex interactions between nutrition and mental health and to develop targeted interventions for improved mental well-being.
