Never thought I would say that huh? This article (click on the title above) by John E. Garst. Ph.D., is very interesting. Dr. Garst feels that a folic acid deficiency in 30% of (Caucasians) people leave them susceptible to illness and possible reactions to aspartame. This would explain why some people experience effects from aspartame while others do not. I swear though that I was still on my prenatal vitamins (which have 1000 mcg of folic acid) when I suffered from what I feel was methanol poisoning from aspartame consumption. Maybe I was not. I really have a hard time remembering much of anything anymore. It drives me crazy. Anyway, if Dr. Garst is correct and people have folate deficiencies and not reactions to aspartame, this is incredible. I want more info now!!! What are the implications? Could a warning be placed on aspartame products? Who else is studying this? Could any studies be done with humans?
