Did you know a healthy diet is critical to your mental health? In fact, many physical and mental disorders are caused by a disruption in the digestive process and compromised intestinal health. When your digestion is sick, it's likely all of your body systems will get sick, including your brain.
Your digestive tract is just a long tube which is open at both ends. To protect itself from toxins and bacteria from the outside, your digestive tract or "gut" is coated with a layer of healthy bacteria, much like the grass which covers healthy soil. This bacterial layer of healthy and essential "gut flora" has many critical functions.
For instance, healthy gut flora:
When the health of the intestinal lining is compromised, the healthy bacteria take a hit, and this allows the populations of toxic bacteria to increase and further degrade the health of the gut.
It's like a line of dominos. Once the good bacteria are reduced, the first domino falls, the gut wall becomes compromised, and very bad things begin to happen.
Once the bad bacteria get a foothold in the gut, the cellular lining of the digestive tract gets inflamed and can't function properly. The digestion and absorption of nutrients becomes impaired. Once digestion is compromised, food particles aren't broken down properly, and the gut begins to "leak". Undigested fragments of food particles flow into the body cavity.
These foreign molecules, especially if they are grain or dairy based peptides, result in an inflammatory and autoimmune reaction within multiple body systems, including the blood-brain barrier.
Once these toxins get into the brain, mental disorders such as autism, depression and schizophrenia can develop. In addition, because digestion is compromised, nutrient and micronutrient deficiencies occur, and these aggravate the body and brain further.
Poor gut health is a function of the world we live in today, and the standard American diet and medical practices so common in our daily lives. Natasha Campbell McBride writes about this in her book Gut and Psychology Syndrome: Natural Treatment for Autism, Dyspraxia, A.D.D., Dyslexia, A.D.H.D., Depression, Schizophrenia
. She writes that some of the most common factors involved in gut health and mental disorders:
Evidence for the link between diet, gut health and mental health includes:
So as you can see, keeping your "gut flora" in good shape is a critical part of staying healthy, both physically and mentally.
The ketogenic diet has a very beneficial effect on mental disorders because it eliminates the sugars, wheat and other grains which are known to effect mental and neurological health.
In fact, sticking to a low carb, ketogenic diet has been shown to be an effective depression treatment, because it gets you off the blood sugar roller coaster associated with a high carb diet.
Low carb diets have also been shown to relieve the symptoms of schizophrenia, and the GAPS diet, one version of a grain free, lower carb diet is being used very successfully to treat ADHD, autism, and other neurological disorders.
