Good question: Most nutritionists have a good knowledge base but my best guess is that sometimes they may read something or attend a seminar or workshop where misleading information like this test is taught and they believe it without doing independent research to verify. You are correct that there is no scientific basis for this test. See http://tinyurl.com/d8s64kr for a good discussion.
