Yes Aspartame is not good for health.Some of the effects of aspartame are as follows-
* While aspartame itself does not increase your caloric intake, it induces further food and sugar cravings, and thereby results in weight gain instead of weight loss.
* Consumption of aspartame over a long period leads to the development of cancer.
* Aspartame can even cause the development of brain tumors, and other conditions of the brain such as Alzheimer's disease, multiple sclerosis, and epileptic seizures.
* Some people have experienced gastrointestinal problems upon consuming aspartame and various products that contain it.
* Studies have shown that excess consumption of aspartame also leads to a condition called aspartame poisoning, that can lead to mental retardation and birth defects. This should answer your question 'is too much aspartame bad for you'?
* Women may be prone to a change in their menstrual cycle when they consume aspartame, and studies have shown a mixed result regarding the relation between aspartame and pregnancy. In any case, to be on the safer side, its consumption should be avoided during this period.
