Mothering Magazine

Dr. Crook was honored by Mothering Magazine as a "Living Treasure" in the July/August 1999 issue.  This is the article which appeared in the magazine:

William G. Crook, MD, is a world-renowned Pediatrician and the author of 13 books, including The Yeast Connection and The Woman and The Yeast Connection Handbook.

When Dr. Crook left Johns Hopkins in 1949 and opened his practice in general pediatrics in Jackson, Tennessee, he knew nothing about the health subjects that interest and excite him today: food sensitivity, food allergy, and "the yeast connection." In reviewing the medical literature of the 1950's, he was surprised to learn the sensitivity to cow's milk and other foods could cause many children to become

irritable, inattentive, tired, and depressed.  He found that he was able to help many of his own patients who had food sensitivities and allergies by changing their diets. Since his first report in Pediatrics in 1961, Dr. Crook has worked to educate physicians, healthcare workers and parents.  This includes recurrent ear problems, headaches, fatigue, muscle aches, and respiratory problems, as well as ADHD. In 1979, he read an article in an obscure Canadian medical journal which described the relationship of the common yeast Candida albicans to health problems which affect many people.  Although he was skeptical at first, he began gathering data which documented this relationship. In 1983, he published the first of a series of best-selling books dealing with yeast-related problems.  During the past 15 years, he has presented his observations to professional and lay groups all over the world. Dr. Crook is a crusader who wants to help people, especially children.  He says, "Unfortunately, more attention is given to  the fuel we put in our automobile's gas tank than to the fuel we give our children."

Sid Baker's Comments from ADHD Conference

At the November 4-7, 1999 conference, ADHD: Causes and Possible Solutions, sponsored by Georgetown University Medical Center and co-sponsored by the International Health Foundation, Sidney M. Baker, M.D., was one of the invited guest speakers.   Here are comments Dr. Baker made in his presentation,

“I’m in private practice.  I’m a research consultant for Immuno Laboratories.  I’m a research consultant for the Children’s Development Data Base, which is interested in understanding the subgroups of autism and its related laboratory and clinical expressions."

“Out on the end of the limb where I practice, the view is somewhat different from the academic roots that I came from.  I like to discuss problems that come up when we begin to think a little bit differently, or at least can perhaps lead to help us think differently about illness." 

“One of my most important teachers in this regard was Linus Pauling, who simply said patients, before they’re given drugs, should be checked to see if they have the right molecules in the right amounts for the individual." 

“Another one of my teachers, I’d like to acknowledge is Dr. Billy Crook.  This man more or less defines a syndrome:  The William G. Crook, M.D. Syndrome.

“The clinical criteria are observance, with his eyes, ears, nose and his feel for things;

“a sense of curiosity, freedom of guile and cynicism;

“a friendliness, generous and prolific with his teaching, persistent, persuasive enough to go and do battle with his colleagues over these issues that he’s been presenting to us and to them for years;

“I think he has finally this weekend seen a triumph of his efforts.  So thank you Billy.”

Following these remarks the audience gave Dr. Crook a standing ovation.
