Position Paper on aspartame and headaches H. J. Roberts, M.D., F.A.C.P., F.C.C.P. 6708 Pamela Lane West Palm Beach, FL 33405 Diplomate, American FAX 561-547-8008 Board of Internal Medicine RECERTIFIED PROFESSIONAL OPINION OF H. J. ROBERTS,M.D.,F.A.C.P.,F.C.C.P. CONCERNING HEADACHES CAUSED BY THE USE OF PRODUCTS CONTAINING ASPARTAME (NUTRASWEET R) Aspartame products should be considered as a causative agent or aggravating factor in persons having unexplained headache. Similarly, patients who are subject to migraine and other types of recurrent headache ought to avoid exposure to ALL products containing aspartame ... even in small amounts, such as gum. This corporate-neutral summary statement has been prepared as general information in response to numerous requests from concerned persons and consumers. There is no bias or malice intended against any company, distributor, researcher or individuals who hold a contrary view. Medical advice should be obtained by persons with persistent headache. STATISTICAL INFORMATION Headache has been the most frequent adverse reaction to aspartame products. It was a major complaint in one out of two persons among the nearly 1,000 aspartame reactors in my data base. This is five times greater than the accepted incidence of headache in the population. Headache also predominates in the more than 10,000 persons who have volunteered their severe reactions to the Food and Drug Administration (FDA. CLINICAL CONSIDERATIONS There is nothing mysterious about the confirmation of aspartame-induced headache. First, it generally improves or ceases within several days after abstaining from these products. Second, the headache tends to recur shortly after resuming them - that is, within minutes or several hours. This sequence is common after unknowingly ingesting aspartame (including drugs and vitamins), even while taking medication to prevent migraine. The following considerations are pertinent: * There is a three-to-one preponderance among women. * Close relatives also are more prone to aspartame reactions, especially headache. * Some reactors emphasized that they had not been previously subject to any type of headache. * About half of the patients with aspartame-induced epilepsy (seizures) in my series -- more than 150 - had experienced severe headache before their first convulsion. * Numerous patients with aspartame-induced headache were initially suspected of having some morbid disease. Their diagnoses included brain tumor, aneurysm of a cerebral artery, and various types of neuropathy ("neuralgia") involving the cranial and cervical (neck) nerves. Nearly all had costly CT scans or MRI studies of the brain -- especially when there were concomitant neurologic and psychiatric complaints (e.g., confusion, memory loss, dizziness, visual impairment, personality change) later also proved to be due to aspartame products. * Aspartame reactors not infrequently develop headaches after ingesting other chemicals. They include monosodium glutamate (MSG),nitrites ("hot dog headache"), and phenylethylamine ("chocolate headache"). * Persons with hypothyroidism (underactive thyroid), hypoglycemia (low blood sugar reactions), diabetes, hypertension, and MSG sensitivity are at greater risk for aspartame-induced headache. CAUSATION Each of the three components of aspartame -- phenylalanine; aspartic acid; the methyl ester, which promptly becomes free methyl alcohol or methanol -- and their multiple breakdown products after exposure to heat or during prolonged storage is potentially neurotoxic, especially for the developing brain. Accordingly, aspartame products should be avoided by pregnant or nursing mothers, infants and children because of many possible adverse developmental and long term brain effects. I have reviewed the likely mechanisms for aspartame headache in my publications. PROFESSIONAL AND CORPORATE DENIAL Persons who suffer aspartame-induced headache are likely to encounter denial of this association by physicians, the FDA and manufacturers. This situation is reinforced by corporate-sponsored "negative scientific studies". I have repeatedly challenged the nature of such studies, especially when the aspartame was administered in capsules or as freshly-prepared cool solutions rather than "real-world" products -- namely, commercial soft drinks and other products that undergo marked changes during exposure to high temperature or after one or more months of storage.
