Diet and lifestyle are the leading "causes" of good health. Most modern diseases have some root cause attached by poor diet and/or a lack of exercise and movement. While eating healthy has been proven to have a positive benefit on health, eating organically has had less scientific support for providing additional nutrition and/or eliminating toxins from our food. Lately though, more studies have pointed out links between pesticides and various health issues and diseases. Since my Mother's Parkinson's diagnosis, I have been following that diseases specific research and there have been many links found between difference pesticides and the onset of the disease. It appears to me that while there is no single cause, there probably is a correlation between our genetics, diet and lifestyle, and the chemicals we come into contact with that "presses on the weak link" of our body's and initiates a disease. It may be as simple as the fact that our livers and other filtering systems cannot keep up with the modern load of toxins and other harmful agents swimming around in our blood.
For these reasons, it may be a good idea to rethink eating organic, if for no other reason than to take a toxic load off the body's liver. Here's the article on how eating organic can reduce the body's pesticide load in a week! (click here)
