Here is an interesting TED talk from Dec 2013 and the research about ketogenic agents for neurological disorders, cancer and wound healing. While studying the effects of gasses on the brains of Navy Seal divers, he developed an approach for metabolically starving cancer cells through diet and compressed oxygen, replacing chemotherapy, surgery, or radiation.
I think the wisdom of Hippocrates sums it up well:
“Let food be thy medicine and medicine be thy food”
