Dom en dik met Aspartaam

Dom en dik met Aspartaam


Een flinke inname van aspartaam kan volgens een nieuwe studie enzymen blokkeren in de hersenen waardoor deze niet meer normaal kunnen gaan functioneren. Deze conclusie doet opnieuw de discussie met betrekking tot aspartaam oplaaien.
Deze zoetstof is ooit in Amerika onder politieke druk door de FDA keuring heengedrukt en overheden nemen nog altijd de kritische studies niet mee in hun mening over deze stof. De industrielobbyisten in Brussel leggen rookgordijnen waardoor politici dom worden gehouden (willen blijven). Dit zie je ook weer goed in Amerika met de hele rel om de stof bisphenol a die vrijkomt uit plastic dat je warm maakt zoals magnetron voeding, koffiebekertjes, babyflesje en drinkflesje (bijv in zonlicht). Ook daar wordt de overheid misleid door onderzoekers die gefinancierd zijn door de industrielobby.
En slank wordt je er ook niet van. Voedsel met kunstmatige zoetstoffen lijken je juist dikker te maken…

Excessive intake of aspartame may inhibit the ability of enzymes in the brain to function normally, suggests a new review that could fan the flames of controversy over the sweetener.
Direct and indirect cellular effects of aspartame on the brain.
P Humphries, E Pretorius, H Naudé
The use of the artificial sweetener, aspartame, has long been contemplated and studied by various researchers, and people are concerned about its negative effects. Aspartame is composed of phenylalanine (50%), aspartic acid (40%) and methanol (10%). Phenylalanine plays an important role in neurotransmitter regulation, whereas aspartic acid is also thought to play a role as an excitatory neurotransmitter in the central nervous system. Glutamate, asparagines and glutamine are formed from their precursor, aspartic acid. Methanol, which forms 10% of the broken down product, is converted in the body to formate, which can either be excreted or can give rise to formaldehyde, diketopiperazine (a carcinogen) and a number of other highly toxic derivatives. Previously, it has been reported that consumption of aspartame could cause neurological and behavioural disturbances in sensitive individuals. Headaches, insomnia and seizures are also some of the neurological effects that have been encountered, and these may be accredited to changes in regional brain concentrations of catecholamines, which include norepinephrine, epinephrine and dopamine. The aim of this study was to discuss the direct and indirect cellular effects of aspartame on the brain, and we propose that excessive aspartame ingestion might be involved in the pathogenesis of certain mental disorders (DSM-IV-TR 2000) and also in compromised learning and emotional functioning.European Journal of Clinical Nutrition advance online publication, 8 August 2007; doi:10.1038/sj.ejcn.1602866.
