Although mental health affecting approximately one out of four people is often in the news, the link between diet and depression is rarely spoken about.
Whilst diet may not change the factors that cause depression, it can impact on how you cope with it. Diet affects the production of hormone and neurotransmitters and these in turn affect your mood and ability to cope with stress.
The neurotransmitter serotonin is critical to helping you balance your mood, cope with anxiety and stress. This is the transmitter that most anti-depressants aim to increase. Serotonin is synthesized from tryptophan, an amino acid found in protein rich foods and in particular in fish, walnuts, oats, pumpkin seeds, legumes and bananas. Tryptophan is then converted into 5-hydroxytryptophan (5-HTP) but before it can be converted iron, vitamin B3 and folate are required. Once 5-HTP is available the co-factors magnesium and B6 are then needed to ensure effective conversion to serotonin.
Not only is diet important in the provision of co-factors and enzymes, it is also important in maintaining a healthy gut microflora. Your gut flora produces neurotransmitters, which can have either a negative or beneficial affect on mood and anxiety levels. Gut flora dysbiosis is one of the reasons why so many people with IBS or food intolerances experience depression, anxiety or mental health issues.
Research shows that if the integrity of your gut lining is compromised then the gut-brain barrier will also be compromised. This means that molecules that should not cross the brain-barrier do cross and trigger neuro-inflammation affecting how you feel and function.
Other factors that contribute to poor mood include blood-sugar imbalance, hormonal imbalance including thyroid issues, nutritional deficiencies, such as essential fatty acids or B12, inflammation and food intolerances. Daylight and exercise has been shown to improve serotonin production, which may be why people tend to feel better when the sun shines!
Trauma, both physical and emotional, even when experienced during childhood, impacts gut integrity and therefore mental and physical health in adulthood. Likewise, chronic stress as it can affect inflammation and gut integrity.
Research often shows that those diagnosed with clinical depression have a 30% to 50% increase in inflammatory markers caused by over activation of the immune system. Short-term inflammation is a protective factor in immunity – think of a bee sting or a swollen ankle. If the inflammation becomes chronic it will eventually cause havoc on the body and can lead to low levels of serotonin and or dopamine, a neurotransmitter the absence of which can lead you feeling unmotivated and hopeless.
