Are There Any Studies That Support The Claim That Chiropractic Can Improve Your Immunity?
Yes, there are… in fact dozens of them. One of the most important studies showing the positive effect chiropractic care can have on the immune system and general health was performed by Ronald Pero, Ph.D., chief of cancer prevention research at New York’s Preventive Medicine Institute and professor of medicine at New York University. Dr. Pero measured the immune systems of people under chiropractic care as compared to those in the general population and those with cancer and other serious diseases. In his initial three-year study of 107 individuals who had been under chiropractic care for five years or more, the chiropractic patients were found to have a 200% greater immune competence than people who had not received chiropractic care, and 400% greater immune competence than people with cancer and other serious diseases.
The immune system superiority of those under chiropractic care did not diminish with age. 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 the normal patients… we have never seen such a positive improvement in a group…”1
In 1991 Patricia Brennan, Ph.D. and other researchers conducted a study that found improved immune response following chiropractic care. The study demonstrated changes in white blood cells. The “phagocytic respiratory burst of polymorphnuclear neutrophils (PMN) and monocytes were enhanced in adults that had been adjusted by chiropractors.”2 In other words, the cells that act like “Pac-Man” eating and destroying bad cells are enhanced through chiropractic care.
