The debate over neurotransmitter interaction in aspartame usage

Area of Science:

• Neuroscience
• Toxicology
• Gastroenterology

Background:

• Aspartame is a common artificial sweetener linked to neurological and behavioral problems.
• Aspartame breaks down into phenylalanine, aspartic acid, and methanol.

Purpose of the Study:

• To investigate how aspartame metabolites, cortisol, and gut microbiota alterations affect brain neurochemistry.
• To understand the mechanisms behind aspartame-induced neurophysiological symptoms.

Main Methods:

• Literature review focusing on aspartame metabolites, stress hormones, and gut dysbiosis.
• Analysis of existing evidence on neurochemical changes and neurophysiological symptoms in consumers.

Main Results:

• Aspartame metabolite phenylalanine, acting as an excitatory neurotransmitter, impacts brain neurochemical composition.
• Elevated cortisol levels and gut dysbiosis may further modulate neuronal signaling.
• These factors collectively contribute to neurobiological impairments observed in aspartame consumers.

Conclusions:

• Aspartame's primary metabolite, phenylalanine, is implicated in neurochemical alterations and associated symptoms.
• Cortisol and gut dysbiosis may exacerbate these effects, leading to neurobiological impairments.
• Further research is crucial to elucidate the specific roles of these factors in aspartame consumers.
