A bland presentation of the food allergy theory: not new, and still unsupported. Kaufmann runs a laboratory where a test for the ""Cytotoxic Effect"" is performed--based on the work of Washington U. School of Medicine researchers who found that certain foods seem to cause white blood cell death in certain individuals, indicating sensitivity. According to Kaufmann, such food sensitivities can cause headaches, dizziness, insomnia, runny nose, itching ear, recurrent sinusitis, palpitations, asthma, chest congestion, nausea, vomiting, stomach fullness, hives, pallor, anxiety, stuttering, indifference, and a best of other problems--including obesity. And, cautions Kaufmann, we may be addicted to ""cytotoxic"" foods to the point that we experience withdrawal when they are eliminated from the diet. He argues the case for ""optimizing health by listening to your body"" (basically, swear off the problem-causers); recommends that readers have cytotoxic testing done; and then offers a food sensitivity diet. This is the usual rotary diet that systematically eliminates com-mon problem foods so that individuals can map out their own particular sensitivities. Uninteresting recipe ideas--sesame seed milk, mushroom burgers--are included. Readers will de better with The Mandells' It's Not Your Fault You're Fat Diet (p. 453)--whose authors have first-hand research experience and a deeper understanding of the possibilities. This is featherweight by comparison.
