Feelings of anxiety, irritability, or depression can occur from time to time. When these feelings become overwhelming, it’s time to take a closer look at why your body is responding in this way. Are you aware that the brain actually sends signals to the gastrointestinal tract? Think of how you feel when you are nervous, frightened, or anxious – you get a sick feeling or a knot in the pit of your stomach. New studies confirm communication between the gut and the brain is a bi-directional flow of information.
We are just beginning to understand that assaults on the gut directly influence brain health. Neurotransmitters such as serotonin, your feel-good hormone, originate from specific cells in the digestive tract. Some types of bacteria can alter what neurotransmitters are being produced in the gut. This new discovery suggests that an unhealthy gut may have a detrimental impact on our nervous systems and our moods.
The digestive system is designed to break down food and deliver nutrients to the bloodstream to nourish the body and the brain. High consumption of refined carbohydrates, such as, sugar and white flour, causes wide blood sugar swings that are difficult for the body to control. Hypoglycemia or low blood sugar often then develops. Stress raises cortisol levels, contributing to problems with controlling blood sugar levels. Hypoglycemia-associated impaired mental health, such as depression and anxiety, is a common side effect.
