Food significantly affects mood and mental health due in part to its influence on neurotransmitter function. Certain nutrients, such as omega-3 fatty acids, B vitamins, and amino acids, are directly linked to brain health and mood regulation. Diets rich in whole foods and antioxidants support cognitive function and may mitigate symptoms of depression and anxiety. Conversely, high sugar and processed foods can lead to emotional and physical energy crashes, highlighting the importance of a balanced diet for overall mental wellness.
