Medicine has certainly turned in this direction. The more we know about a disease process, the more we adjust treatments accordingly. When we know what causes a disease, we can avoid acquiring it. In the newest realm of medicine, even stem cell research has this potential to prevent or reverse genetic disease.
Much of our basic health has to do with diet and exercise. We know adjusting preventable causes of disease can garner amazing results. Most of the time these lifestyle adjustments don't just repair physical well being, but mental and spiritual health as well.
Just a few decades ago, doctors warned against exercise; "you'll have a heart attack!" We now know that this sentiment is outdated; it is akin to discouraging someone from going to school because they may fail. The benefits outweigh the risks, and those benefits can help people love and enjoy life.
My specialty of podiatry is now at the beginning of a revolution to bring preventative medicine to our feet. Helping the foot to function as it was intended, without the influence of modern shoes and orthotics, can be lifechanging! Like you would consult a doctor before beginning an exercise regimen, you want to visit myself before you begin discarding orthotics, using minimal running or casual/dress shoegear or going barefoot!
