Tens of millions of people around the world have suffered from depression at some point in their lifetime. Depression is even thought to be a common occurrence in the lives of people because there are certain physical factors that can trigger depression. It just varies in degree and intensity, depending on how the affected person reacts to the situation.

Depression is a psychiatric disorder that affects a person’s mood and behavior. It is associated with the feeling of dejection, hopelessness and loss of interest in things that were once interesting, like sex.

The physical factors that trigger depression include: i) Loss of a job; ii) Death or loss of a loved one; iii) Illness; iv) Accident and v) Nutritional deficiency.

Depression can be difficult to treat if it continues for a long time. In this case, it might be good to look into a person’s nutrition to see if an underlying deficiency is behind the prolonged condition. Depression is now being linked to these conditions:

1. Deficiency in Essential Fatty Acids

Essential fatty acids that are found in omega-3 fats have a vital role in optimizing the performance of neurotransmitters in the brain. A deficiency in omega-3 fats are often linked to depression. Fishes like tuna, salmon and mackerel are excellent sources of omega-3 fatty acids.

2. Deficiency in Amino Acids

Amino acids are the building blocks for the body’s production of neurotransmitters which include serotonin, noradrenalin, adrenalin and dopamine. These chemicals play an important role in making you feeling happy and able to cope up with stressful situations.

Stress and poor diet are associated in a way because they can cause the depletion of neurotransmitters which can help avoid depression.

3. Deficiency in B Vitamins, Vitamin C, Magnesium, Iron and Zinc

A deficiency in these vitamins and minerals can lead to depression because they are all needed by the body to change amino acids into neurotransmitters.

4. Blood Sugar Imbalance

An imbalance in blood sugar levels can result from low-protein intake and a diet high in carbohydrates. This can also result in the shortage of neurotransmitters which produce the chemicals that help to combat depression.

5. Food Allergies

Allergies to foods that contain wheat, cow’s dairy, oranges, eggs, yeast, shellfish, nuts and soya are known to trigger depression.

Depression is linked to the increase in the body’s histamine levels due to the intake of allergens.

6. Heavy metals

Mercury, lead, copper and cadmium are toxic metals that are associated with symptoms which include anxiety and depression.

You can avoid these toxic metals by increasing your fiber intake. Eating foods rich in fiber, antioxidants, zinc and calcium can help in reducing these toxic metals.
