British agency raps hair test for "food intolerance." The British Advertising Standards Authority (ASA) has concluded that the Bionetics "food intolerance" test is not valid. In response to two complaints, the agency evaluated an ad for the test which had stated: "The bionetics team have developed an innovative new diagnostic test (that requires just a few strands of your hair), which can establish whether or not your body has become intolerant to 123 of the most common problem foods and ingredients." In response to an ASA inquiry, the company stated:

The ASA concluded that testimonials were not sufficient evidence to justify claims that Bionetics methods of hair testing could "establish whether or not your body has become intolerant to 123 of the most common problem foods and ingredients" and "report on . . . accumulations of toxins, problem pathogens and nutritional deficiencies."

Bionetics Limited is located in Camberly, UK. Its Web site states that its machine scanner evaluates a hair sample by "analyzing the energy fields in the root of the hair" and that "these fields make up a complete energetic 'signature' of the body." The test report then recommends a program that includes foods to avoid, nutritional supplements, herbs and homeopathy "needed to eliminate your stresses." Applied kinesiology (muscle testing), radionics, and the Bionetics test itself have no scientific validity.


FTC hits " reducing soap" marketers. The Federal Trade Commission has charged sellers of the “Centro Natural de Salud Obesity Treatment” with making false and unsubstantiated claims that their product causes rapid, substantial, and permanent weight loss. The “treatment” consists of three pills, taken with breakfast, lunch, and dinner, and a bar of “reducing soap” to “reduce dress sizes.” The claims were made in Spanish-speakng infomercials. The defendants, Centro Natural Services, Inc., Xavier Rodriguez, and Rocio Diaz (Rodriguez's wife) are located in Santa Ana, California. The FTC complaint charges that they falsely claimed their treatment would cause users to (a) lose substantial amounts of weight rapidly, without reducing calorie intake; (b) safely to lose as much as a half pound per day for multiple weeks and months; and/or (c) lose weight permanently. The soap was claimed to reduce flab and prevent stretch marks by "compressing tissue." [FTC: Three pills and special soap “obesity treatment” won’t wash away the pounds. FTC news release, Oct 17, 2006]
