The digestive system is 9 metres or 30 feet long and consists of the mouth, stomach, pancreas, small intestines, liver, gallbladder and colon. Its primary role is to convert the food we eat into usable nutrients and at the same time remove toxic waste and by-products from the body. We don't tend to pay much attention to what goes on in the digestive tract unless something goes wrong or specific symptoms appear. This is understandable as the Autonomic Nervous System unconsciously controls digestion.
A quick snapshot of digestion shows the process starts when we begin to chew our food and saliva is produced. Saliva contains the digestive enzymes, amylase and lipase, that start the process of breaking down carbohydrates and fats.  An antibacterial enzyme, lysozyme, is also present and it destroys bacteria.  In the stomach, acids are produced to denature and breakdown food, in particular proteins. From the stomach, the food travels into the small intestine, where the pancreas secretes an array of digestive enzymes to further breakdown the food. Bicarbonate is also secreted and neutralises the stomach acid, thus allowing the digestive enzymes to function optimally. In the small intestines, the microscopic food particles are absorbed through the intestinal villi and enter the bloodstream. In the blood, these particles travel to the liver, which converts the inactive vitamins and amino acids into their active forms. The liver also secretes bile into the small intestines, which helps to breakdown fats, remove toxins and enhance bowel motions.
From the small intestine, the remaining food; mainly fibres, water and waste products move into the colon where excess water is reabsorbed and faeces are formed. Individual bacteria convert the prebiotic fibres, which are found in various foods including; fruit, vegetables and legumes, into short-chain fatty acids. These acids, in turn, provide nutrients for the beneficial bacteria that inhabit the colon and the cells that line the colon walls. 
The digestive tract is not only a place where the body absorbs nutrients from food and eliminates waste. It is home to the second-largest nervous system outside the brain; the Enteric Nervous System.  Millions of nerve cells line the intestinal tract and continuously send information to the brain. With this information, the brain can alter chemical processes which affect not only digestive function, but also energy, sleep patterns, thoughts and moods. How well would the brain function if the gut was toxic and inflamed? Would the brain receive the correct messages from these nerves, or would the communication be somewhat off-kilter? Mood disorders, Autism,  Parkinson's  and possibly Alzheimers disease all have origins in the gut and faulty communication between the Enteric Nervous System and the brain.
Enterochromaffin cells are quite rare and make up less than 1% of the total intestinal surface. However, these unique cells produce over 90% of the body's feel-good, happy brain chemical, serotonin. Besides improving moods, anxiety and depression, serotonin enhances gastrointestinal motility and secretions, while alleviating nausea and improving visceral hypersensitivity or pain. 
Good gut health is paramount as 70% of the body's immune system calls the digestive tract home, and who thrives in a dirty, toxic and unhappy home? . Poor gut immune function is a leading cause of inflammation, allergies, reoccurring infections and autoimmune diseases.
Within the intestinal tract lives a conglomerate of over 1000 different bacteria species, collectively known as the microbiome.  These bacteria live in a symbiotic relationship with us and when we get sick, so do they and respectively when they get sick, so do we. Keeping the digestive tract robust and healthy, positively affects the microbiome. This, in turn, improves immune health, reduces allergenic reactions, eliminates Dysbiosis and has positive effects on mental health, cardiovascular health and weight management.  Interestingly, magnesium deficiency alters the gut microbiome and leads to depressive like behaviour. 
The digestive system is excellent in communicating to us when it's unhappy, or when we've eaten something we shouldn't have and it's unwell. Below are some of the more common symptoms indicating substandard gut health.
|Abdominal pain||Crohn's disease||Loose, mushy stools|
|Abnormal coloured stools||Diarrhoea||Metallic, sour taste in the mouth|
|Bad breath||Flatulence||Painful bowel motions|
|Belching||Food Intolerances||Rancid stools or gas|
|Bloating||Frequent or urgent urination||Reflux or heartburn|
|Bloody stool||Gas – 30 minutes after food||Rumbling stomach|
|Colitis||Indigestion or fullness 2-4 hours||Skin Disorders|
|Constant worry||Inflammatory Bowel Disease||Strong body odour|
|Constipation||Irritable bowel syndrome||Tired after eating|
|Craving sweets||Leaky Gut Syndrome||Undigested food in stool|
It can be difficult enough for the digestive tract to maintain a healthy balance. Still, when poor lifestyle habits, environmental factors and medications are also placed into the mix, it becomes overwhelming to preserve good health. Below are some of the more common causes of poor digestive health.
|Antibiotics||Food additives||Poor diet|
|Artificial flavourings||Heavy Metals||Protein Pump Inhibitors|
|Binge drinking||Ibuprofen||Recreational drugs|
|Birth Control Pill||Inadequate sleep||SIBO|
|Candida||Irritable Bowel Syndrome||SIFO|
|Coeliac Disease||Junk food||Stress|
|Constipation||Low fibre diet||Vitamin A deficiency|
|Diarrhoea||Mould||Vitamin D deficiency|
|Daily alcohol||NSAID's||Zinc deficiency|
A healthy digestive system relies on a nourishing diet, adequate nutrient absorption and a robust ability to remove waste.
