Research performed by Dr Ronald Pero Ph.D (a cancer prevention expert and professor of medicine at NYU) showed in a 3 year study involving over 100 long-term chiropractic patients that the participants who took proper care of their spine and nervous system with periodic chiropractic check-ups had an immune system that was 200% more competent than the rest of the population – and this strengthening of the immune system did not diminish with age either! Dr Pero stated “When applied in a clinical framework, I have never seen a group other than this chiropractic group to experience a 200% increase over normal patients. This is why it is so dramatically important. We have never seen such a positive improvement in a group.” In another study that analysed blood samples researchers found that the cells that act like “Pac-Man” (i.e. PMN’s and Monocytes) eating and destroying bad cells and bacteria are enhanced through chiropractic care.
