This question has captivated many scientist and clinicians for many years, however, it would seem that there is no clear answer. The more research conducted the more complex the question becomes. The interaction between the endocrine system and the nervous system has been dubbed the ‘gut-brain axis’ and is depicted to be interacting in many regular functions and systems within a healthy body and diseases.
There has been research conducted from a range of microbiology and neuroscience papers on the topic of the gut-brain axis and its involvement in health and disease.
There are parasites, which could very well influence your brain and gut, they are highly evolved and are highly specific mechanisms that take advantages of their hosts. One of these parasites is called Toxoplasma gondii, a resourceful protozoan parasite that’s found on a global scale and can infiltrate the body of all warm-blooded mammals.
Toxoplasma gondii, is usually indigested through the contamination of food, water or accidently through cat feces. Investigators conclude that about 60 million US alone are infected with this. This parasite can lead to toxoplasmosis, varying from mild, flu-like symptoms to the brain causing behavioural changes. An example of this would be that rats no longer recognise cats, or their smell, which in turn puts them in a deadly and risky situation. Evidently, this works in support of the parasite as it would infect it’s new host, the cat.
New date conducted revealed the role of the gut-brain axis as part of the pathogenesis unusual disease. The by-products produced by bacterial overgrowth in the gut (propionic acid), have now been connected to the autism spectrum disorders. Bacterial overgrowth in the gut be triggered by excessive and unregulated use of antibiotics, which are now become a growing problem globally. As the youth are more exposed to antibiotics, the gastrointestinal effects of unregulated use can very well be linked to the new developing disorders.
Remember that our gut is a “second brain” and always think what you eat, how you eat, where you eat and what time you eat.
