What is Nutritional Psychiatry

How often has mom told us “eat a little something and you will feel better”?  Think about it...your brain never stops working.  All day and all night, your brain keeps your bodily functions operating.  Using all that energy requires constant fuel.  What you eat directly affects your bodily functions, including the brain.  So the better you eat, the better your brain will work.  Conversely, when you overeat, or consume junk food, or otherwise skimp on nutrition, you are prone to sadness and anxiety.


This is the basic principle of nutritional psychiatry.


Today's research is showing a correlation between good nutrition and the reduction of free radicals, inflammatory cells, the kinds of bacteria that live in the intestinal tract, as well as how you feel, and behave.  Eating highly refined sugars is now linked to impaired brain function and the aggravation of mood disorders like depression.  Nutritious foods with vitamins, minerals, and antioxidants protects the brain from oxidative stress or free radicals produced as the body oxygenates.


Serotonin is a substance, a neurotransmitter, that regulates sleep, appetite, evens out moods, and reduces pain.  The vast majority of serotonin is produced in the gastrointestinal organs.  So there is a direct connection between the transmitters in the gut and the serotonin that keeps our lives on track.  As proper nutrition is processed by the body, it helps regulate our moods as well.


Studies have found that the risk of depression is lowered by 25% to 35% in persons who follow a Mediterranean or Japanese diet.  These eating plans are high in vegetables, fruits, unprocessed grains, and fish and low in meats and dairy.  They also shun processed and refined sugars and other foods.


A food diary is an easy way to see if it works.  Try one of these diet plans and after about a week start keeping a record of what you ate through the day and then how you felt the next day.  Continue this for another week and see if there is a change in your mental attitude.  This is also a way that you can find trigger foods by reintroducing them into your eating plan and then tracking how your emotions are affected.  Also note if you have increased or decreased energy and sleep patterns.


Nutritional psychiatry is applying these studies to patients who suffer from various forms of mental illness especially anxiety and depression.  It appears to be an effective method to reduce or eliminate medications that can have other side effects that adversely affect some people. 


Combining healthy eating with approved psychiatric counseling sessions is one of the non-invasive techniques that can greatly improve lives. 


A 2020 study has revealed that anti-inflammatory fats like Omega-3 are connected to a lower risk of depression.  This study found that women who consumed fish twice per week had a 25% lower risk of depression as compared to those women who ate fish less than twice per week.


Higher risk of depression was found in people who failed to get enough magnesium (beans, lentils, peas, avocado, nuts, whole grains, and dark chocolate).  The same was found in those who were deficient in zinc (oysters, pumpkin seeds, cashews).
