As an ex-professional scientist with no connections to any company or the FDA, I have looked at some of the data published in peer-reviewed scientific literature and there is no evidence whatsoever that Aspartame has ANY effect on the Nervous system in Humans using it as a sweetener. None, Zero, Nada, f**k all. Monsodium glutamate is far, far more toxic. Normal fruit juice, or beer or wine - all have higher methanol levels and methanol is neurotoxic.Â
Â
Unless you basically eat a 50mg/kg body weight or more of the stuff, it`s safer than 99% of what you find in any health food store - for me that would be 5g of Aspartame. Don`t believe me if you don`t want to, but having a friend of a friend of a friend that gets headaches after drinking diet soda is NOT evidence of anything.Â
Â
It is one of the most studied compounds in the history of science and while there are thousands of internet claims of cancer, headaches, neurotoxicity and the like, the only potential issue is with Phenylketonuria, as one of the metabolites of Aspartame is Phenylalanine.Â

Aspartame consumption: lack of effects on neural function
- The Nathan S. Kline Institute for Psychiatric Research, Center for Neurochemistry, Orangeburg, NY USA
Aspartame is NOT a neurotoxin in doses anyone could or would consume. If you eat 5g of Aspartame in one dose, then it must be Natural Selection at work, because that is just plain stupid. It is metabolised very quickly in the gut to aspartate and phenylalanine, both are amino acids that are found in every protein you`ve ever eaten. There is also a small amount methanol produced, which is metabolised to formaldehyde, then formate by the liver. There is more methanol in beer than is produced by whopping does of Aspartame that nobody would EVER eat. Also bear in mind that only a small proportion of Aspartame metabolites are actually found in the bloodstream.Â
Everything is a poison at some level of consumption. Capsaicin, for instance. I`ve even come across cases of people who have died from drinking too much water. So water must be toxic, too.Â
