Definition
Chiropractic Nutrition is that specialty within the chiropractic profession that deals with the overall factors that affect the patient's ability to maintain the manipulative correction and thus sustain better neurological integrity. The Chiropractic Nutrition Specialist will perform extensive research on the patient's previous health history, ethnicity, and any family history related to what the patient is being treated for. Patients fill out questionnaires concerning dietary and sleep patterns and previous or present symptomology. A nutrition examination would be performed to assess areas such as absorption rates, adrenal function, kidney health, lung health etc. The patient is often instructed on how to check the pH of their saliva and urine, test for the presence of Candida Albicans, etc., at home. Outside laboratory testing includes blood, urine, hair analysis, food allergy testing etc. The patient's prescription and over the counter medications are recorded and analyzed.
