Food to improve your mood! Dietary changes to decrease depression

Depression, as it is referred to in this series of articles, refers to depressed mood, unexplained feelings of sadness, low energy. Trying the tips in this series of articles may help reduce these symptoms but they are not a substitute for formal treatment of clinical depression (feelings of worthlessness or hopelessness, significant impairment of daily functioning and thoughts of suicide).

A poor diet is associated with increased rates of depression. Depressive symptoms are common in those whose diet largely consists of fast foods (hamburgers & pizza), processed pastries (doughnuts, muffins), foods high in sugar content, and foods with preservatives (1).

Conversely, addressing your diet and making healthy changes will help decrease your likelihood of depression! This article will explore several dietary changes you might consider to increasing your chances of fighting off depression.

First, a ‘traditional’ diet composed of beef, fish, whole grains, fresh fruits and vegetables is associated with reduced risks of depression (1). Additional considerations should be considered but this diet is a good alternative to fast foods, etc.

A Mediterranean diet has been linked to reductions in depression. This diet consists of increased amounts fresh fruit and vegetables, nuts, legumes, fish and poultry (grilled not fried), and decreased amounts of red meat and whole-fat dairy (2).

A Ketogenic diet has demonstrated antidepressant and mood stabilizing effects. This diet includes high fat, low to moderate proteins and reduced carbohydrates. Common foods on a Keto diet include meat, fish, butter, eggs, cheese, heavy cream, oils, nuts, and avocados. Foods higher in carbohydrates such as grains, rice, beans, potatoes, sweets, milk, cereals, fruits are reduced or eliminated from the diet (3,4).

The most heavily researched dietary factor associated with reductions in depression is increased intake of omega-3 fatty acids especially those high in eicosapentaenoic acid (EPA). Omega-3 acids are commonly found in fish, nuts, and seeds and fish oil supplements (5,6).

Preliminary findings indicate that adding a variety of vitamins and minerals (e.g., a multivitamin) helps reduce depression (7).

Maintaining healthy gut bacteria is associated increased availability of the most common neurotransmitters associated with decreasing depressive symptoms (serotonin and dopamine) (8).

Interestingly, a study involving adults whose diet consisted of standard potions of meat reported improvement in mood when switching to a vegetarian diet (9).

Though long-term benefits are yet to be determined, Therapeutic fasting, which involves brief periods of fasting (up to 48 hours) with water and gradual reintroduction of foods such as fruit and rice is associated with improvement in mood and sense of well-being (10).
