What you get
Mackerel is the richest source of omega-3 fatty acids, necessary for the development of the nervous system and for the health of the brain.
Sweetcorn provides vitamin B6, needed for converting the amino acid known as tryptophan into the neurotransmitter serotonin. Depressed people have been found to have lower levels of vitamin B6.
Peppers contain the nutrient folate and depression is a common symptom of folate deficiency.
Hot peppers contain capsaicinoids, which cause pain in the mouth. This causes a flood of endorphins to be sent to the site of the pain, bringing a mood boost that lasts for about an hour.
