About John Cartmell, MS



John W. Cartmell was born and raised in Pasco, Washington. He has been a Certified Nutritionist since 2004, receiving a Master of Science degree in Nutrition Research from Bastyr University of Natural Medicine in Kenmore, WA. He did his master's thesis on "Nutrition in Fibromyalgia".

The Diet Advisor website was founded in 1998 to help clients promote better health through improved nutrition and lifestyle. By analyzing age, weight, gender, lifestyle, diet, digestion, supplements, medications, and general health status, he identifies the client's nutritional strengths and weaknesses and provides recommendations on how best to promote optimal health through improved nutrition.

He became interested in nutrition during premed studies at the University of Washington in the early 1970s. Since then he has been an advocate of proper nutrition, seeking to better understand the balance of health and the imbalance of disease.
His interest and experience in nutrition spans over forty-five years during which his knowledge of nutrition helped him recover from 3 major health problems.

In 1984 he was diagnosed with leukemia and cured in 1988 by a bone marrow transplant. He credits dietary revisions during and after the transplant for his successful transplant and recovery (95% of the other transplant patients perished). In1985 he became licensed as a massage practitioner specializing in deep tissue massage and producing three videos on massage technique. He retired from massage in 2012.

In the mid 1990s, he developed symptoms of Chronic Fatigue and Fibromyalgia, a soft tissue condition of widespread pain. He fully recovered his health after resolving several digestive issues.

In 2003, diverticulitis led to bowel injury and peritonitis during an episode of heavy lifting. While reintroducing foods after surgery he discovered several food sensitivities that had contributed to his bowel inflammation and injury. Addressing these concerns helped him recover normal gastro-intestinal health.

With the arrival of middle age, he has successfully addressed his own issues of inflammation, acid reflux, dysphagia, maldigestion, weight gain, increases in blood pressure, blood sugar and cholesterol, memory problems, and fatigue - increasing his overall knowledge and ability to help others.

As a Certified Nutritionist he specializes in clinical nutrition, helping patients meet specific nutritional needs in conditions like acid reflux (GERD), allergies, arthritis, Attention Deficit Hyperactive Disorder (ADHD), autism, autoimmune disorders, cancer, chronic fatigue syndrome (CFS), chronic inflammation, depression, diabetes, digestive problems, fibromyalgia, heart disease, high cholesterol, hypertension, Inflammatory Bowel Disease (Crohn's disease, ulcerative colitis), insomnia, Irritable Bowel Syndrome (IBS), Leaky Gut Syndrome, memory problems, obesity, Post Traumatic Stress Disorder (PTSD), age-related degenerative disease, and other chronic conditions of ill health.
