Multiple Diseases Caused by Undiagnosed Food Intolerance

Specialists tend to consider that aspect of a patient’s illness which is of special concern only to their own specialty. When the patient’s illness is unraveled, it is often found that a common factor underlies his many symptoms.

Two illustrative case histories are included in this summary:

 Joan A., age 43, developed arthritis with incapacitating low-back pain at age 23, migraine at age 35, and chronic diarrhea at age 37 years. Investigations carried out by her gastroenterologist were noninformative, she was never the less advised to avoid all cereals except rice, on the supposition that she had celiac disease. Her arthritis and headaches cleared when she did this (both were due to wheat). She then decided to also avoid rice, and her diarrhea cleared. She then realized that all her problems were diet related and that foods had caused different reactions to different systems.

Alex N., age 66, developed diabetes mellitus at age 52, controlled initially by diet and orinaseR. At age 63 he developed arthritis of his right hip. At age 64 he required insulin to control his diabetes. At age 65 he became insulin insensitive, developing antibodies beef insulin. He was therefore placed on pork insulin with benefit. Because he was becoming increasingly handicapped by his arthritis and because he had developed antibodies to beef insulin he decided to avoid beef, and when he did so his arthritis cleared.

Further examples will be given in the presentation.
