New Study by Ramazzini Institute Confirms Aspartame Carcinogenic

Dr. Morando Soffritti of the European Ramazzini Foundation will present the
results of a new study confirming the carcinogenicity of Aspartame on April 23,
2007 at the Mount Sinai Medical School of New York, where he also will receive
the prestigious Irving J. Selikoff Award.

Aspartame, the artificial sweetener made by Searle/Monsanto was found to cause
cancer in laboratory animals already in the original studies that were submitted
to the FDA when approval was asked to put it on the market. The justified doubts
of the FDA's scientists were overridden when Donald Rumsfeld called in his
political markers.

Another study conducted in Spain by Trocho et al came to similar results,
identifying a transformation of parts of the molecule into formaldehyde as a
probable cause. Later, a study of the European Ramazzini Foundation confirmed
the sweetener's carcinogenicity in laboratory rats and seriously questioned its
safety. But industry, through the European Food Safety Authority, succeeded in
diverting attention from the damaging findings, calling them an artifact of the
study's design.

Now, a new, long-term study on Aspartame has been completed giving lower dosages
but confirming, once again, the carcinogenicity of the sweetener. See the
announcement from the Ramazzini Foundation here:

New aspartame data to be presented at Mount Sinai School of Medicine in NYC, USA

A second study conducted by the European Ramazzini Foundation (ERF) confirms the
carcinogenicity of aspartame. The results of this study will be presented April
23, 2007 at the Mount Sinai Medical School of New York, where ERF Scientific
Director Morando Soffritti will receive the third Irving J. Selikoff Award.

Aspartame is an artificial sweetener consumed by hundreds of millions of people
worldwide. It is used in over 6,000 diet products including soft drinks, chewing
gum, candy, desserts, yogurt as well as in pharmaceuticals, in particular,
syrups and antibiotics for children. In 2005, the European Ramazzini Foundation
published important experimental data demonstrating the carcinogenicity of
aspartame. These data demonstrated for the first time that aspartame is a
carcinogenic agent, inducing various types of malignant tumors in rats, even at
dose levels currently considered acceptable for humans.

As soon as carcinogenic effects were perceived during this first study, the ERF
began a second long term experiment, administering aspartame at low doses in
feed to rats beginning during fetal life.

In a world exclusive, Italian news station TG2 announced on April 13th that the
European Ramazzini Foundation will present the results of this second study at
the Mount Sinai School of Medicine at the end of April when Scientific Director
Dr. Morando Soffritti will receive the third Irving J. Selikoff Award. The news

IT: Il secondo studio sull'aspartame della Fondazione Europea Ramazzini (FER)
conferma la cancerogenicità dell'aspartame. I risultati saranno presentati il 23
aprile a New York, al Mount Sinai Medical School.

L'aspartame è un dolcificante artificiale consumato nel mondo da oltre 200
milioni di persone. E' utilizzato in oltre 6.000 prodotti, fra i quali bevande
light, gomme da masticare, dolciumi, caramelle, yogurt, farmaci, in particolare
sciroppi e antibiotici per bambini. Nel 2005, la Fondazione Europea Ramazzini ha
pubblicato importanti dati sperimentali che dimostravano la cancerogenicità
dell'aspartame. Venne dimostrato sperimentalmente per la prima volta che
l'aspartame è un agente cancerogeno in grado di indurre vari tipi di tumori
maligni, anche a dosi tutt'oggi ammesse per l'alimentazione umana.

Fin dal momento della percezione della cancerogencità dell'aspartame, la FER
avviò un secondo studio, somministrando aspartame a basse dosi nel cibo ai ratti
a partire della vita fetale.

In anteprima mondiale un servizio del TG2 ha anticipato che la Fondazione
Europea Ramazzini presenterà i risultati del secondo studio nei prossimi giorni
a New York, al Mount Sinai Medical School of Medicine, dove il Direttore
Scientifico Dottor Soffritti riceverà il Premio Selikoff per i suoi studi
sull'aspartame.

ERF announces launch of dynamic web portal: raw data from long term
carcinogenesis studies now available for download

On 5 April 2007 the European Ramazzini Foundation (ERF) launched its new
dynamic, bi-lingual web portal at www.ramazzini.it. For the first time, users
may now download raw study data from selected long term carcinogenicity
bioassays conducted at the ERF’s Cesare Maltoni Cancer Research Center of
Bentivoglio (Bologna). [Vedi testo completo per l'italiano]

The principle objective of this initiative is to make Ramazzini raw data from
published studies available for use by the greater scientific community for the
conduct of risk assessments and additional research. Two reports detailing 1)
neoplasms by individual animal and 2) statistical analysis of primary tumors,
may be downloaded free of charge in .pdf or .xml format for experiments on
selected compounds including aspartame, methanol, MTBE and TAME.

In addition, the new web portal includes a searchable index of the last ten
years of the Foundation's scientific publications with the option to download
the full text of most articles in pdf. Users are also able to consult recent
national and international press, submit CVs for job openings, and make online
donations to the Foundation using major credit cards.

In an effort to facilitate the European Ramazzini Foundation's dialogue with the
public, a weekly blog entry will address current issues in environmental science
and public health. Blog readers are invited to comment on the weekly topic, ask
questions to the Scientific Direction, and suggest topics for future blog
postings.

The Ramazzini portal, which also links to the National Ramazzini Institute and
the Collegium Ramazzini, is uniquely bi-lingual, with all content available
side-by-side in Italian and English. The site was designed by Kate Havran and
developed by Nowhere s.r.l. under the project direction of Kathryn Knowles of
ERF.

IT: Il 5 aprile 2007 la Fondazione Europea Ramazzini (FER) ha lanciato il nuovo
e dinamico portale web bilingue su www.ramazzini.it. Gli utenti, per la prima
volta, potranno scaricare i dati grezzi sperimentali estrapolati da saggi di
cancerogenesi a lungo termine, condotti al Centro di Ricerca sul Cancro Cesare
Maltoni (CRCCM) di Bentivoglio (Bologna).

Il principale obiettivo di questa iniziativa è rendere disponibili i dati grezzi
di studi pubblicati alla comunità scientifica, per permettere loro di condurre
analisi sui rischi e ulteriori ricerche. Due report, che contengono dati su: 1)
tumori benigni e maligni per animale; e 2) analisi statistica dei tumori primari
benigni e maligni, sono disponibili gratuitamente in formato .pdf o .xml per
esperimenti su composti stabiliti tra i quali aspartame, metanolo, MTBE e TAME.

Inoltre, il nuovo portale web include un indice per la ricerca delle
pubblicazioni della Fondazione degli ultimi dieci anni, con la possibilità di
scaricare i testi integrali della maggior parte degli articoli in formato .pdf.
Gli utenti hanno altresì la possibilità di consultare la stampa recente, sia
nazionale che internazionale, inviare CV per proporre la propria candidatura ed
effettuare donazioni alla Fondazione utilizzando le carte di credito più
diffuse.

Allo scopo di facilitare il dialogo tra la Fondazione Europea Ramazzini e il
pubblico, uno speciale blog d’entrata, ogni settimana, sarà dedicato alle
attuali problematiche in tema di scienze ambientali e salute pubblica. Ai
lettori del blog sarà richiesto un commento sull’argomento della settimana,
mentre la Direzione Scientifica si renderà disponibile a rispondere alle domande
e accetterà proposte sulle tematiche da presentare sui futuri blog.

Il portale Ramazzini, che comprende anche l’Istituto Nazionale Ramazzini e il
Collegium Ramazzini, è interamente bilingue, con tutti i contenuti disponibili
sia in italiano che in inglese. Il sito è stato progettato da Kate Havran e
sviluppato da Nowhere s.r.l. , sotto la direzione di progetto di Kathryn Knowles
della FER.

method

The Ramazzini methodology is characterized by systematic and integrated project
design, consistency over time, and homogeneity of approach. Agents are selected
for study on the basis of their potential diffusion and on the adequacy of
existing experimental evidence.
The Ramazzini study design closely mirrors the human condition in which persons
may be exposed to agents in all phases of life for varying lengths of time. A
distinctive characteristic of Ramazzini carcinogenicity studies is that all
rodents are kept under observation until natural death. This lifespan protocol
is in contrast with most laboratories where rodents are sacrificed at 110 weeks
of age (representing about 2/3 of the lifespan). Cancer is a disease which
predominately affects the aging, with 80% of tumors diagnosed in humans over the
age of 55. It is therefore of paramount importance to observe how an agent
affects laboratory animals in the last third of their lives. One of the
challenges in industrial and environmental carcinogenesis today is the highly
complex identification and quantification of diffused carcinogenic risks.
Diffused carcinogenic risks are those to which almost the entire population of
the planet may be exposed. They include agents which are slightly car
cinogenic at any dose, low or extremely low doses of carcinogenic agents of any
kind, or mixtures of small doses of carcinogenic agents.
In the case of diffused carcinogenic risks, it is not sufficient to follow the
standard protocol used in ordinary experiments, but rather it is necessary to
conduct what we define as “mega-experiments.” Mega-experiments are those in
which a vast number of rodents per sex/per group are used in order to highlight
the significance of differences, even very small ones, in the variability of
response. In these experiments, rodents are exposed to agents in all phases of
development and observed for the lifespan to allow the agent to express its full
carcinogenic potential.

metodo

Il metodo Ramazzini è caratterizzato da un disegno sperimentale sistematico e
integrato, dalla consistenza della metodologia nel tempo, e dall’omogeneità
dell’approccio. Gli agenti sono selezionati sulla base della loro diffusione e
sulla adeguatezza dell’evidenza sperimentale esistente.
Il disegno sperimentale Ramazzini cerca di riprodurre in laboratorio la
condizione umana, dove gli individui possono essere esposti in tutte le fasi
della loro vita, e per una durata variabile. Una caratteristica distintiva degli
studi di cancerogenesi condotti nei laboratori Ramazzini è che i roditori
vengono tenuti sotto osservazione fino alla morte naturale. Questo protocollo si
differenzia da quelli adottati dalla maggior parte dei laboratori, in cui i
roditori vengono sacrificati a 110 settimane di età (circa 2/3 dell’arco di
vita). Il cancro è una malattia che colpisce soprattutto gli anziani, con l’80%
dei tumori diagnosticati nelle persone oltre i 55 anni. È quindi di fondamentale
importanza osservare gli eventuali effetti dell’agente studiato anche durante
l’ultimo terzo della vita degli animali.
Fra le sfide più complesse di oggi nell’ambito della cancerogenesi ambientale e
industriale vi sono l’identificazione e la quantificazione dei rischi
cancerogeni diffusi, ai quali può essere esposta quasi tutta la popolazione del
pianeta. Questi rischi includono sia agenti cancerogeni deboli a qualsiasi dose,
sia dosi basse o estremamente basse di agenti cancerogeni anche forti, oppure
miscele di bassissime dosi di agenti cancerogeni.
Nel caso di rischi diffusi, non è sufficiente seguire il protocollo utilizzato
negli esperimenti ordinari, ma è invece necessario condurre quelli che chiamiamo
“mega-esperimenti”. I mega-experimenti utilizzano un numero molto elevato di
roditori per sesso/per gruppo e sono per questo in grado di mettere in evidenza
la significatività di differenze anche piccole nella variabilità della risposta.
I roditori vengono esposti in tutte le diverse fasi dello sviluppo e vengono
osservati fino alla morte naturale, così da mettere in evidenza il potenziale
cancerogeno totale dell’agente studiato.

Aspartame Not Linked to Cancer

In an article published in the March 2006
issue of Environmental Health Perspectives
(EHP) Soffritti et al. (2006) of the European
Ramazzini Foundation of Oncology and
Environmental Sciences (ERF) reported that
aspartame was associated with an increase in
lymphomas and leukemias, transitional cell
carcinomas of the renal pelvis and urether,
malignant schwanomas of peripheral nerves,
and hyperplasia of the olfactory epithelium.

After the publication of the ERF aspartame
study (Soffritti et al. 2006), the
European Commission asked the European
Food Safety Authority (EFSA) to assess the
ERF aspartame carcinogenicity study
results as a matter of high priority following
the publication (EFSA 2005).

The EFSA’s Scientific Panel on Food Additives,
Flavorings, Processing Aids and Materials in
Contact with Food (AFC), an 18-member
panel that consisted of independent regulatory
scientists and toxicologists, assessed the
ERF aspartame carcinogenicity study using
not only the ERF publication but also more
extensive primary data and reports provided
by ERF (EFSA 2006).

Concurrently, the
U.K. Food Standards Agency requested
the opinion of the U.K. Committee on
Carcinogenicity of Chemicals in Food,
Consumer Products and Environment
(COC) on the quality, analysis, and interpretation
of the results of the ERF aspartame
carcinogenicity study (Soffritti et al. 2006).

After a lengthy evaluation process, on
5 May 2006, the EFSA published a 44-page
report (EFSA 2006). A summary comment
of the EFSA report on ERF study included
the following:

The increased incidence of lymphomas/leukaemias
reported in treated rats was unrelated to aspartame,
given the high background incidence of chronic
inflammatory changes in the lungs and the lack of
a positive dose–response relationship. … The
slight increase in incidence of these tumours in rats
fed aspartame is considered to be an incidental
finding of the ERF study and can therefore be dismissed.
(EFSA 2006)

The preneoplastic and neoplastic lesions of the
renal pelvis, ureter and bladder occurring primarily
in female rats along with renal calcification were
most probably treatment-related, at least at the
higher doses. It is widely accepted that the effect is
a high dose effect of irritant chemicals or chemicals
producing renal pelvic calcification as a result of
imbalances in calcium metabolism, specific to the
rat. The Panel considers that these effects are of no
relevance for humans. (EFSA 2006)

The data on total malignant tumours do not provide
evidence of a carcinogenic potential of aspartame.

… [T]he aggregation of all malignant
tumour incidences or all malignant tumour-bearing
animals for statistical purposes is not justified,
given that, as explained above, the lymphomas/
leukaemias and the renal tumours should have
been excluded from the analysis. (EFSA 2006)

Concerning the malignant schwannomas, … the
numbers of tumours were low, the dose–response
relationship, while showing a positive statistical
trend in males, was very flat over a wide dose
range and there is also uncertainty about the diagnosis
of these tumours. … [T]his finding can only
be fully evaluated following a histopathological
peer-review of all relevant slides related to the nervous
system in the ERF study and if necessary also
from the historical controls. (EFSA 2006)

Furthermore, the COC’s March 2006
minutes on the publication of the ERF aspartame
study (Soffritti et al. 2006) concluded,

… [I]n view of the problems in the design of the
study and some concerns about the microbiological
status of the colony, it was not possible to
draw conclusions about the potential carcinogenicity
of aspartame from the results.

The study by Soffritti et al. (2006) has
major flaws that bring into question the
validity of the findings. Its publication in
EHP is not without consequence to the
reputation of the National Institute of
Environmental Health Sciences or to the
health of the U.S. public. Publication of
invalid and misleading research results relating
to products such as aspartame, which can
be of benefit in the battle against obesity and
have a history of safe use, are a disservice to
the tax-paying citizens of the United States.

The author is employed by Ajinomoto USA,
which sells aspartame.

How to distort the scientific record without actually lying


http://www.ramazzini.it/fondazione/foundation.asp

the mission

The European Foundation of Oncology and Environmental Sciences “B. Ramazzini” is
an independent, non-profit foundation, dedicated to the prevention of cancer for
more than 35 years. Our mission is to undertake initiatives aimed at the
prevention of tumors via a strategy based on scientific research, the training
of specialized personnel, and the diffusion of information on environmental and
industrial carcinogenic risks. The activities of the Foundation focus primarily
on the experimental identification and quantification of carcinogenic risks and
on the evaluation of the efficacy and tolerability of drug therapies and active
ingredients that may be used to prevent the development and/or progression of
cancer.
The Foundation’s facilities include the Cesare Maltoni Cancer Research Center
(CMCRC) in Bentivoglio (Bologna, Italy), where one of the world’s largest and
longest existing programs of carcinogenicity bioassays is conducted, and an
Epidemiological Research Center. Currently, the Foundation is conducting long
term experimental studies to detect the potential carcinogenic effects of
exposure to electromagnetic fields generated from electrical currents and from
the radio-base stations of cellular telephones. Also underway is a large
integrated program of studies to better quantify the carcinogenic risks of
artificial sweeteners.

Methyl alcohol was administered in drinking water
supplied ad libitum at doses of
20,000, 5,000, 500, or 0 ppm to groups of male and female
Sprague-Dawley rats 8 weeks old at the start of the experiment.
Animals were kept under observation until spontaneous death.
Ethyl alcohol was administered by ingestion in drinking water at a
concentration of 10% or 0% supplied ad libitum to groups of male and
female Sprague-Dawley rats; breeders and offspring were included in
the experiment.
Treatment started at 39 weeks of age (breeders), 7 days before mating,
or from embryo life (offspring)
and lasted until their spontaneous death.
Under tested experimental conditions, methyl alcohol and ethyl alcohol
were demonstrated to be carcinogenic for various organs and tissues.
They must also be considered multipotential carcinogenic agents.
In addition to causing other tumors, ethyl alcohol induced malignant
tumors of the oral cavity, tongue, and lips.

aspartame (methanol, formaldehyde) toxicity research summary: Rich Murray
2007.04.19
http://groups.yahoo.com/group/aspartameNM/message/1404

One liter aspartame diet soda, about 3 12-oz cans,
gives 61.5 mg methanol,
so if 30% is turned into formaldehyde, the formaldehyde
dose of 18.5 mg is 37 times the recent EPA limit of
0.5 mg per liter daily drinking water for a 10-kg child:

Aspartame Controversy, in Wikipedia democratic
encyclopedia, 72 references (including AspartameNM # 864
and 1173 by Murray), brief fair summary of much more
research: Murray 2007.01.01


Dark wines and liquors, as well as aspartame, provide
similar levels of methanol, above 120 mg daily, for
long-term heavy users, 2 L daily, about 6 cans.

Within hours, methanol is inevitably largely turned into
formaldehyde, and thence largely into formic acid -- the
major causes of the dreaded symptoms of "next morning"
hangover.

Fully 11% of aspartame is methanol -- 1,120 mg aspartame
in 2 L diet soda, almost six 12-oz cans, gives 123 mg
methanol (wood alcohol). If 30% of the methanol is turned
into formaldehyde, the amount of formaldehyde, 37 mg,
is 18.5 times the USA EPA limit for daily formaldehyde in
drinking water, 2.0 mg in 2 L average daily drinking water.

http://groups.yahoo.com/group/aspartameNM/message/1286
methanol products (formaldehyde and formic acid) are main
cause of alcohol hangover symptoms [same as from similar
amounts of methanol, the 11% part of aspartame]:

methanol (formaldehyde, formic acid) disposition:
Bouchard M et al, full plain text, 2001: substantial
sources are degradation of fruit pectins, liquors,
aspartame, smoke: Murray 2005.04.02

"According to model predictions, congruent with the data in the
literature [Dorman et al., 1994; Horton et al., 1992], a certain
fraction of formaldehyde is readily oxidized to formate,
a major fraction of which is rapidly converted to CO2 and exhaled,
whereas a small fraction is excreted as formic acid in urine.

However, fits to the available data in rats and monkeys of Horton et
al. [1992] and Dorman et al. [1994] show that, once formed, a
substantial fraction of formaldehyde is converted to unobserved forms.

This pathway contributes to a long-term unobserved compartment.

The latter, most plausibly, represents either the formaldehyde that
[directly or after oxidation to formate] binds to various endogenous
molecules [Heck et al., 1983; Røe, 1982] or is incorporated in the
tetrahydrofolic-acid-dependent one-carbon pathway to become the
building block of a number of synthetic pathways
[Røe, 1982; Tephly and McMartin, 1984].

That substantial amounts of methanol metabolites or by-products are
retained for a long time is verified by Horton et al. [1992] who
estimated that 18 h following an iv injection of 100 mg/kg of
14C-methanol in male Fischer-344 rats,
only 57% of the dose was eliminated from the body.

>From the data of Dorman et al. [1994] and Medinsky et al. [1997],
it can further be calculated that 48 h following the start
of a 2-h inhalation exposure to 900 ppm of 14C-methanol vapors
in female cynomolgus monkeys,
only 23% of the absorbed 14C-methanol was eliminated from the body.

These findings are corroborated by the data of Heck et al. [1983]
showing that 40% of a 14C-formaldehyde inhalation dose remained
in the body 70 h postexposure.

In the present study, the model proposed rests on acute exposure
data, where the time profiles of methanol and its metabolites were
determined only over short time periods
[a maximum of 6 h of exposure and a maximum of 48 h postexposure].

This does not allow observation of the slow release from the long-term
components.

It is to be noted that most of the published studies on the detailed
disposition kinetics of methanol regard controlled short-term
[iv injection or continuous inhalation exposure over a few hours]
methanol exposures in rats, primates, and humans
[Batterman et al., 1998; Damian and Raabe, 1996;
Dorman et al., 1994; Ferry et al., 1980; Fisher et al., 2000;
Franzblau et al., 1995; Horton et al., 1992; Jacobsen et al., 1988;
Osterloh et al., 1996; Pollack et al., 1993; Sedivec et al., 1981;
Ward et al., 1995; Ward and Pollack, 1996].

Experimental studies on the detailed time profiles following
controlled repeated exposures to methanol are lacking."

CASE SUMMARY: Four patients diagnosed with fibromyalgia
syndrome for two to 17 years are described.
All had undergone multiple treatment modalities with
limited success.
All had complete, or nearly complete,
resolution of their symptoms within months after
eliminating monosodium glutamate (MSG)
or MSG plus aspartame from their diet.
All patients were women with multiple comorbidities
prior to elimination of MSG.
All have had recurrence of symptoms whenever MSG
is ingested.
