Et bilde som er delt av mange på Facebook og Twitter de siste dagene har provosert meg nok til at jeg fisket frem Photoshop og korrigerte det litt. Her er min versjon som dere gjerne må spre i sosiale medier. (Del gjerne lenken bildet er koblet til.)

Aspartam bs

Ja, min endring består i å legge til stempelet: 100% certified bullshit. Bildet blir nemlig mye mer korrekt slik.

Erik Arnesen, mannen bak ernæringsbloggen Sunn Skepsis, har skrevet et kort svar på Facebook som jeg også tar med for de som vil ha noe mer substans:

En gjennomgang av over 500 vitenskapelige studier avdekket ingen store farer ved det nåværende inntaket av aspartam i befolkningen. Det samme mener både FDA og EFSA (hhv USA og EUs mattilsyn): 40-50 mg aspartam pr kg kroppsvekt er trygt – det tilsvarer mange liter med brus. Brus og saft kan inneholde maks 600 mg/liter. You do the maths.

Når det gjelder metanol: Ja, det dannes når aspartam brytes ned i kroppen. Men et glass appelsin- eller tomatjuice gir oss faktisk MER metanol enn lettbrus med aspartam! Fenylalanin er en aminosyre som også finnes naturlig i mange matvarer, og mengden vi får i oss via lettbrus o.l. er ubetydelig sammenliknet med kosten forøvrig.

Jeg skrev også litt om aspartam i min store vaksinebloggpost, og jeg siterer meg selv:

Men aspartam har vi hørt mye om. Det er visstnok farlig? Nei! Aspartam er et av de tilsetningsstoffene det er forsket mest på, og 30 år med forskning har ennå ikke kunnet vise at det er farlig i de mengdene som er lovlig i mat, og enda mindre de mikroskopiske mengder som finnes i vaksiner. En metaanalyse utført i 2007 sa følgende (min utheving):

Aspartame is a methyl ester of a dipeptide used as a synthetic nonnutritive sweetener in over 90 countries worldwide in over 6000 products. The purpose of this investigation was to review the scientific literature on the absorption and metabolism, the current consumption levels worldwide, the toxicology, and recent epidemiological studies on aspartame. Current use levels of aspartame, even by high users in special subgroups, remains well below the U.S. Food and Drug Administration and European Food Safety Authority established acceptable daily intake levels of 50 and 40 mg/kg bw/day, respectively. Consumption of large doses of aspartame in a single bolus dose will have an effect on some biochemical parameters, including plasma amino acid levels and brain neurotransmitter levels. The rise in plasma levels of phenylalanine and aspartic acid following administration of aspartame at doses less than or equal to 50 mg/kg bw do not exceed those observed postprandially. Acute, subacute and chronic toxicity studies with aspartame, and its decomposition products, conducted in mice, rats, hamsters and dogs have consistently found no adverse effect of aspartame with doses up to at least 4000 mg/kg bw/day. Critical review of all carcinogenicity studies conducted on aspartame found no credible evidence that aspartame is carcinogenic. The data from the extensive investigations into the possibility of neurotoxic effects of aspartame, in general, do not support the hypothesis that aspartame in the human diet will affect nervous system function, learning or behavior. Epidemiological studies on aspartame include several case-control studies and one well-conducted prospective epidemiological study with a large cohort, in which the consumption of aspartame was measured. The studies provide no evidence to support an association between aspartame and cancer in any tissue. The weight of existing evidence is that aspartame is safe at current levels of consumption as a nonnutritive sweetener.

Jeg nevnte også formaldehyd der, ettersom det finnes i noen vaksiner, og henviste da til denne artikkelen:

Concerns about safety have focused on formaldehyde in part because high concentrations of formaldehyde can damage DNA (the building block of genes) and cause cancerous changes in cells in the laboratory. Although formaldehyde is diluted during the manufacturing process, residual quantities of formaldehyde may be found in several current vaccines. However, formaldehyde does not appear to be a cause of cancer in man. Further, animals exposed to large quantities of formaldehyde (a single dose of 25 mg/kg or chronic exposure at doses of 80-100 mg/kg/day) do not develop malignancies.

The average quantity of formaldehyde to which a young infant could be exposed at one time may be as high as 0.2 mg. This quantity of formaldehyde is considered to be safe for two reasons:

» First, formaldehyde is essential in human metabolism and is required for the synthesis of DNA and amino acids (the building blocks of protein). Therefore, all humans have detectable quantities of natural formaldehyde in their circulation (about 2.5 ug of formaldehyde per ml of blood). Assuming an average weight of a 2-month-old of 5 kg and an average blood volume of 85 ml per kg, the total quantity of formaldehyde found in an infant’s circulation would be about 1.1 mg, a value at least five-fold greater than that to which an infant would be exposed in vaccines.

» Second, quantities of formaldehyde at least 600 fold greater than that contained in vaccines have been given safely to animals.

Sånn. Da er det fint om folk slutter å spre slikt vås. Kthx.
