The gut is an organ that actually has its own nervous system, called the enteric nervous system (ENS). This system’s main function is to control digestion, swallowing, breaking down food, blood flow for nutrient absorption, and elimination. The ENS talks to the central nervous system (CNS) through the vagus nerve, which connects the gut to the brain. Irritation in the gut sends signals to the CNS that trigger mood changes. Therefore, what you eat directly affects brain function.
Stress and fear alter the good gut bacteria. Low gut flora is associated with impaired glucose (blood sugar) control and obesity.
A diagnosis of Irritable Bowel Syndrome (IBS) greatly increases symptoms of anxiety and depression.
The digestive tract is very sensitive to emotion. Anxiety, anger, sadness, happiness, fear, among others, can all trigger changes in the gut. Your intestinal distress can be the cause of or product of emotional symptoms such as stress, anxiety, or depression. Stress, depression, and anxiety can alter intestinal movement resulting in inflammation and/or infection.
What the Gut?
FOOD HAS THE POWER TO CAUSE ILLNESS AND IT HAS THE POWER TO HEAL. WHAT KINDS OF FOODS YOU CHOOSE MAKES A HUGE DIFFERENCE IN OVERALL HEALTH AND WELLNESS.
The guts immune system is the largest immune system in the body. 95% of serotonin (the feel good hormone) is stored in the gut. Serotonin is responsible for sleep, appetite, pain sensitivity, mood, and overall well-being. Your emotions have an effect on your digestive system. (Ever have to suddenly go to the bathroom before a big exam, speech or presentation?). Since 95% of serotonin is stored in the gut, dietary changes are usually more effective in treating depression than medication. Medications mask symptoms. Food can actually change gut flora and help heal the gut.
What we eat early on in life affects our gut health later. It sets us up for optimal health or possible disease. The first 2-3yrs of life have a huge impact on our gut health as we age.
Out of control inflammation causes disease. The immune system controls inflammation. The gut manages the immune response. All connected.
Good bacteria can keep cortisol and adrenaline levels balanced to combat stress.
The 3 most common disruptions to the gut:
- Antibiotics
- Infection
- Stress
And….Exposure to substances that change the bacteria: environmental chemicals, foods (sugar, salt, fat, gluten), water (chlorine), drugs (antibiotics). Lack of nutrients to support the good bacteria
What does your gut do?
• Aids in digestion and absorption of nutrients.
• Creates a physical barrier against harmful invaders, such as parasites, viruses, bad bacteria
• Acts as a detoxification system to lessen the work load of your liver
- Supports immune system response
- Helps control inflammation
The Take Home: The mind and the gut are connected. Unhealthy gut=unhealthy brain.
So, what can we do to help the gut stay healthy? Pro and Pre-biotics!
