Question: I know some doctors say that the artificial sweetener Aspartame is a neurotoxin. What is your opinion? Do you think it is safe? Thank you.

Dr. Hibberd’s answer:
Aspartame is found as NutraSweet and Equal and can be used in both cold and warm foods. People who have a condition called phenylketonuria should avoid this sweetener. Phenylketonuria is a birth defect that causes an amino acid called phenylalanine to build up in your body. Many studies have concluded that it specifically does not cause headaches, seizures, Alzheimer’s disease, Parkinson’s disease, lupus, or multiple sclerosis. In fact, no unsafe health consequences of aspartame have been identified, and it is quite safe.
