I believe balance between both modern medicine and homeopathic/dietary methods for true health.
There are many ways we can all care for ourselves...and what we eat is huge. I believe this is step one. Diet has been linked to cancer, headaches, diabetes, heart health, etc. Obesity is a plague of its own. We tax smokers, increase health care costs, etc. But no action has been taken that I'm aware of to do the same for morbid obesity. Although similiar health risks are involved.
Modern medicine has brought to light some amazing medical interventions, surgeries, technologies, medicines, etc. I have had my experience with modern medicine event though I am in relatively excellent health.
I am 35, and have spinal issues that I take 7 medications for multiple times each day. These medicines have some scary long term use side effects, from liver disease to....just not something I am looking forward to. If I lived in a state with medicinal marijuana I could likely stop taking every single one of these pills and have less side effects.
On the other hand, surgical and other procedures have helped significantly.
As with everything, there must be balance.
