What about dodgy genes?

I hear you! I’ve got those concerns. I have a family history of alcoholism, mood issues, cardiovascular problems and cancer. But I also have a number of centenarians or near centenarians in my family tree, so hopefully I got the ‘good’ genes. Either way, in most instances, our genetics don’t predetermine our health and lifespan. In rare cases they do, but for most of us it can be a little more complicated. We used to think that one gene would determine one disease, but scientists have learned so much more about genetics in the past 30 years or so.

There was a time back in the 1990’s when scientists thought that by sequencing the human genetic code, they would be able to unravel the mysteries of disease. It was such a lofty and worthy goal, and it would have been amazing if it had solved the genetic piece of the health puzzle. Unfortunately, the sequencing of the genome created more questions than answers. Turns out most diseases are not caused by a single gene, or even by a number of genetic factors. They are caused by the complex interplay between genes and the environment in which these genes exist, both the internal and external impacts. Epigenetics is the name given to the study of these impacts on the expression of genes. And it’s of little surprise that diet and lifestyle were found to be two of the biggest factors influencing epigenetic changes, which changes can ultimately lead to poor health. Over time more articles will be added here to help explain the interplay between genes and our health.

Signs of Autoimmunity

Signs of Autoimmunity

Autoimmune disease is on the rise, just like many other chronic health issues of the 21st Century. It is estimated that around 5% of Australian’s experience some type of autoimmune condition. That is over a million people, and alarmingly, 75% of those living with autoimmunity
