Aspartame causes brain tumors and other incurable diseases.

All sorts of rumors and claims are circulating on the Internet and in chatrooms about aspartame (Nutrasweet, Equal) causing various diseases...brain tumors...multiple sclerosis...Alzheimer's disease...lupus...seizures...and others.

The theory is these problems develop because aspartame is converted to methanol in the body. Methanol is metabolized to formaldehyde and formic acid...which can cause neurotoxicity and blindness.

It's true that aspartame is converted to some amount of methanol, but the amount produced by aspartame is MUCH LESS than what's produced by other foods such as citrus fruits and tomatoes.
