Few people are aware of the connection between nutrition and depression. We always assume that depression is more biochemical or emotional.

On the contrary, food we eat can play an important role in the beginning, as well as the severity and duration of the depression. We can easily notice the change in the food patterns that occur during depression and may include: Poor appetite, skipping meals, and a dominant desire for sweet foods. From my wide experience as a Nutritionist, and from the studies that I read, I know now that nutritional factors are linked with human cognition, behavior, and emotions.

The most common mental disorders currently present in many countries are: depression, bipolar disorder, schizophrenia, and obsessive-compulsive disorder (OCD). They are associated with deficiencies in neurotransmitters (serotonin, dopamine, noradrenaline, and γ-aminobutyric acid).

Our dietary intake patterns, and the ones of the general population in many Asian and American countries reflect that they lack many nutrients, especially essential vitamins, minerals, and omega-3 fatty acids that we can find in our daily foods.

The amino acids tryptophan, tyrosine, phenylalanine, and methionine are helpful in treating many mood disorders including depression. Tryptophan, is usually converted to serotonin (the happy hormone) that can help us sleep and be tranquil.

Omega-3 fatty acids

B-complex vitamins

Mood improvement is particularly associated with improved vitamin B2 and B6 status. In women, baseline vitamin B1 status was `linked with poor mood and an improvement in the same after 3 months was associated with improved mood.

Vitamin B12

Clinical trials have indicated that Vitamin B12 delays the onset of signs of dementia. Adolescents who have a borderline level of vitamin B12 deficiency develop signs of cognitive changes.[43]Vitamin B12 is mainly present in meat, fish, eggs, milk and cheese.

Vitamin B9(Folate)

It has been observed that patients with depression have blood folate levels.[44] A study has shown that 500 mcg of folic acid enhanced the effectiveness of antidepressant medication.[45] It is not clear yet whether poor nutrition, as a symptom of depression, causes folate deficiency or primary folate deficiency produces depression and its symptoms. Folate is mainly present in green leafy vegetables, beans, peas, lentils and fuits.

Current research in psychoneuroimmunology and brain biochemistry indicates the possibility of communication pathways that can provide a clearer understanding of the association between nutritional intake, central nervous system, and immune function thereby influencing an individual’s psychological health status. These findings may lead to greater acceptance of the therapeutic value of dietary intervention among health practitioners and health care providers addressing depression and other psychological disorders.
