Understanding & Overcoming Depression

Depression is a significant global mental health issue, affecting millions of people worldwide. It is estimated 3.8% of the population experience depression and approx. 280 million people in the world have depression (WHO, 2023). Due to its prevalence, there is an urgent need to create awareness and comprehensive, holistic treatment approaches.

What is Depression?

While everyone experiences sadness, clinical depression is fundamentally different. Sadness is a normal human emotion characterised by the feelings of unhappiness, low mood and sense of loss, disappointment or grief. Clinical depression, however, causes persistent feelings of sadness and loss of interest, followed with somatic and cognitive changes that negatively affects how you feel, think, and handle daily activities (Chand & Arif, 2023).

The ICD classifies depression into the following types:

Depressive Episode: Characterised by a persistent low mood, loss of interest or pleasure in activities. It often includes reduced concentration, self-esteem decline, sleep and appetite. Severity (mild, moderate, or severe) depends on intensity of the symptoms and number (ICD-10, 2019).
Recurrent Depressive Disorder: involves repeated depressive episodes without a history of mania. Severity (mild, moderate, or severe) depends on intensity of the symptoms and number (ICD-10, 2019).
Persistent Depressive Disorder (Dysthymia): This refers to a long-lasting, chronic low mood persisting for several years, where the symptoms are not intense or prolonged enough to meet the criteria for mild, moderate or severe recurrent depression,
Bipolar Affective Disorder (formerly Manic Depression):This disorder involves two or more episodes of significant mood and activity disturbance—ranging from elevated mood with increased energy (hypomania or mania) to low mood with reduced energy (depression).

Diet and Depression: Foods That Fight Depression

A growing body of scientific evidence highlights a powerful connection between diet and mental health. What we eat can directly influence brain chemistry, inflammation, and gut health, all of which are linked to mood regulation (Firth et al., 2020). It is observed in individuals with depression that they tend to either eat too much or too little. They experience sluggishness and weight gain when eating too much, and exhaustion from eating too little. Nonetheless, a poor diet makes matters only worse. Incorporating “foods that fight depression” can be a valuable component of a holistic treatment plan.

Fatty Fish: Salmon, mackerel, and tuna are rich in Omega-3 fatty acids. Consumption of Omega-3 has shown to boost learning and memory. Fatty fishes also have a naturally occurring high amount of vitamin D is linked to lower levels of depression.
Leafy Greens and Whole Grains: Spinach, kale, and whole grains are excellent sources of B vitamins, particularly folate (B_9). Low folate levels have been linked to depression, as this vitamin is essential for synthesizing mood-regulating neurotransmitters like serotonin and dopamine (Głąbska et al., 2020).
Nuts and Seeds: Nuts are a great source of omega-3 fatty acids, which support mental health and help combat depression. Cashews, rich in magnesium, aid in delivering oxygen to the brain. Almonds contain phenylalanine, a compound that promotes the production of dopamine and other mood-enhancing neurotransmitters and may also ease Parkinson’s symptoms.
Dark Chocolate (in moderation): Rich in flavonoids, dark chocolate can improve blood flow to the brain and has been shown to boost mood, though it should be consumed mindfully due to its sugar and fat content.

These foods great for depression help by providing the essential nutrients the brain needs to produce neurotransmitters, reduce inflammation and protect against cellular stress, thereby supporting overall mental resilience.

When to Seek Help?

While self-care practices and diet are beneficial for one’s mental health. But they are not a substitute for professional help, especially when symptoms are severe or persistent. It is important to recognise when to seek help is a big step toward recovery. Mental health professionals and various helpline numbers, help provide essential guidance and intervention. Comprehensive treatment for depression typically involves a combination of approaches tailored to the individual. Standard evidence-based treatments include:

Psychotherapy: Cognitive Behavioural Therapy (CBT) and Interpersonal Therapy (IPT) are effective in helping individuals identify and change negative thought patterns and improve relationships (Chand & Arif, 2023).
Medication: Antidepressants or mood stabilizers may be prescribed by a psychiatrist to help correct chemical imbalances in the brain (Chand & Arif, 2023).
Lifestyle Changes: Regular exercise, a balanced diet, sufficient sleep and stress management techniques are powerful adjuncts to clinical treatment.

For individuals with severe or treatment-resistant depression, inpatient or outpatient rehabilitation services can provide a structured and supportive environment. Rehabilitation for depression, typically included therapeutic activities, skill-building workshops, group therapy sessions and continuous monitoring to ensure the individual’s safety and the efficacy of the treatment.

Conclusion

Depression is a complex but treatable illness. By following a holistic approach, individuals can navigate the path to recovery. With the right combination of therapy, support systems, lifestyle changes and sometimes structured rehabilitation, healing is achievable. The journey, however, begins with the courageous step of asking for help and the commitment to embracing a comprehensive plan for well-being.
