A fascinating area of research that has been gaining a lot of momentum concerns the influence of our microbiome with overall health and disease. The human microbiome encompasses the totality of microbes, their genetic elements and their environment. Studies have shown an association between the human oral microbiota and risk of chronic diseases, such as cardiovascular disease, diabetes, obesity and certain cancers. There are many factors that influence microbial populations, such as dietary factors, exposure to pathogenic organisms and overall health status. The relationship between the host and its resident commensal and pathogenic organisms is complex and dynamic; and an exciting area of science with so much yet to be discovered.

We are all familiar with the role genetics play in shaping our physical appearance. You might have inherited your mother’s green eyes or your father’s broad shoulders. We too understand how genes influence our risk or resilience to developing various conditions. In previous The Genetic Link blog features we’ve linked genes with substance abuse, cancer, epilepsy and tropical diseases. But what I’ve been pondering lately is how and to what extent our unique genetic code is involved in making us who we are by shaping our personality, behavior, social interactions and thought processes. Perhaps you’re familiar with the idea of nature versus nurture, or gene versus environment studies. What I want to know is how much of who I am is due to my genetic make-up versus how much is a result of that complicated mix of my early experiences, social and cultural influences, family interactions, education…in other words, my environment? These almost philosophical questions are tackled on a daily basis by psychologists, psychiatrists and neurologists; and I am absolutely riveted by this research.
