Does
aspartame cause allergic reactions?
No. Although a few people have claimed that they have
experienced allergic-type symptoms related to consuming
aspartame, these anecdotal reports are not confirmed by
carefully controlled scientific studies done at the National Institutes of Health
and at six major academic medical centers. The results of these studies done
with people who were convinced that aspartame caused their allergic
reactions clearly demonstrate that aspartame is not associated with allergic
reactions.
A wide variety of foods can cause allergic reactions in some people. Those
who suspect a food allergy should seek diagnosis and treatment from a
qualified medical professional, such as a board-certified allergist. Self-diagnosis
can delay treatment of a more serious medical problem.

Is
there a relationship between aspartame and headaches?
No. A carefully controlled study was done at Duke University Medical Center
with people who were convinced that aspartame caused their headaches. This
study, which was published in the New England Journal of Medicine,
demonstrated that aspartame does not cause headaches or migraines.
Headaches are one of the most common human complaints. Many factors can
cause headaches, ranging from stress and sleep disturbances to physical
illnesses. It is potentially dangerous to assume that a headache is related to
aspartame, when the cause may be a serious physical or psychological condition.

Is
aspartame safe for people with epilepsy?
Yes. The Epilepsy Institute of New York and the Epilepsy Foundation
of America state that aspartame is safe for use by people with epilepsy.
Numerous scientific studies were done in animals and in people who were
convinced that aspartame caused their seizures and in children with epilepsy.
The results of these studies demonstrate that aspartame does not cause or
worsen seizures.
