Ongoing work by researchers into how aspartame affects the brain has linked the artificial sweetener with learning and memory deficits in mice. The offspring of male mice that consumed aspartame at levels equivalent to much lower doses than those deemed safe by the U.S. FDA demonstrated spatial learning and memory deficits over the course of a controlled 16-week exposure. The most recent research is an extension of a study which linked aspartame consumption to anxiety in mice, with effects extending up to two generations. "The thing we noticed here, unlike the anxiety (research), this went only one generation. It was...
