Te dni sem za neko nalogo "raziskovala" umetna sladila in njihov vpliv na zdravje, predvsem aspartama in neotama, ki je bil z Direktivo v EU odobren 22.10.2010 . Našla sem veliko gradiva, ob prebiranju katerega sem se zgrozila. Prilagam del članka iz ene od slvenskih spletnih strani - ki je v bistvu prevod ameriškega članka.

Namen tega posta je izključno osveščenost potrošnikov. Vsak bo z informacijo storil, kar bo hotel. Ali zavrgel, kot še eno propagando, ali pa malo pogledal na deklaracije izdelkov...

 

Toksičnost aspartama

Aspartam je ime za umetno sladilo, ki se pogosto uporablja za slajenje pijač in ostalih napitkov ter živil (jogurti, žvečilni, bonboni, pudingi, mueslji, vitamini itd.). Prodaja se pod različnimi zaščitenimi imeni, kot so Equal, NutraSweet, Canderel, Spoonful itd. Leta 1965 ga je po naključju odkril James M. Schlatter, kemik družbe G.D Searle & Company, ko je iskal zdravilo proti čiru na želodcu. Ko je ustvaril aspartam iz aspartanske kisline in fenilalanina, je okusil njegov sladek okus.

Lastnosti

Aspartam je sintetična spojina dveh izoliranih amino kislin, fenilalanina in aspartanske kisline, kemično povezano z metanolom (lesni alkohol). Njegovo kemično ime je N-L-aaspartyl-L-phenylalanine-l-methyl ester (APM). Ima kalorično vrednost 4 kcal/g, vendar je 180-krat slajši od sladkorja in se ga zato uporablja v zelo majhnih količinah, saj je njegov doprinos k skupni kalorični vrednosti živila zato zanemarljiv. Občutljiv je na segrevanje, ker razpade in izgubi večji del svoje sladkosti, zato se ga uporablja predvsem v hladnih živilih. Prav tako je občutljiv na izdelke, ki imajo visoko pH vrednost. Pri sobni temperaturi je najbolj obstojen pri pH 4,3, kjer je njegova razpolovna doba skoraj 300 dni.

Samo v ZDA je dodan že več kot 6000 izdelkom. Uporabniki poročajo, da okus aspartama ni povsem enak okusu sladkorja, poleg tega pa okus sladkosti ostane v ustih dalj časa. Za razliko od ostalih umetnih sladil, ki vplivajo na izločanje inzulina (saharin, ciklamat ...), aspartam nima tega učinka.

Aspartam je sestavljen iz 40 % aspartanske kisline, 50 % fenilalanina ter 10 % metanola in pri presnovi razpade na naštete kemikalije, pri nadaljnji presnovi pa tudi na formaldehid in mravljinčno kislino:

  • aspartanska kislina: sodi med kemikalije, ki v večjih količinah deluje kot eksotokskin in tako povzroča nevrološke poškodbe. Veliko študij na živalih je pokazalo poškodbe na določenih delih možganov in posledično razvoj kroničnih bolezni (mnenja znanstvenikov glede vprašanja, ali ima aspartanska kislina enak učinek tudi na ljudi, so deljena). Po uživanju aspartanske kisline v aspartamu lahko pride do resnih kroničnih nevroloških motenj in drugih akutnih simptomov (glavoboli, migrene, nespečnost, trebušne bolečine, težave s spanjem, napadi tesnobe, depresije in astma), ena od najpogostejših težav pa je zmanjšanje sposobnosti pomnjenja.
  • fenilalanin: aminokislina, ki je v možganih normalno prisotna. Bolniki s prirojeno genetsko motnjo fenilketonurijo ne morejo normalno presnavljati fenilalanina, zato pride pri uživanju aspartama do povečane koncentracije fenilalanina v možganih, kar lahko v skrajnih primerih privede tudi do smrti (zaradi tega morajo izdelki, ki vsebujejo aspartam, nositi opozorilo, da je izdelek vir fenilalanina). Do previsoke koncentracije fenilalanina v možganih pa lahko pride tudi pri zdravih ljudeh, zlasti v kombinaciji aspartama z ogljikovimi hidrati, kar lahko privede do zmanjšanja nevrotransmiterja serotonina, to pa povzroči čustvene motnje in depresijo. Fenilalanin razpade na diketopiperazin, agent, ki povzroča možganski tumor, kar so pokazale laboratorijske raziskave na podganah. Šest mesecev po tem, ko je aspartam dodan v gazirane pijače, ga 25 % razpade v diketopiperazin.
  • metanol: sprošča se iz aspartama, ko se ta segreje na 30 stopinj Celzija ali več. Zaradi tega aspartama ni priporočljivo toplotno obdelovati. Lahko pa pride do izločanja metanola pri nepravilnem skladiščenju, kar je zlasti pogosto v poletnih mesecih. Metanol je smrtonosen strup, ki se zelo počasi izloča iz organizma in povzroča celo vrsto dolgotrajnih zdravstvenih težav. V telesu se hitro absorbira in razpade na mravljinčno kislino in formaldehid, ki je prav tako smrtonosen živčni strup. V kombinaciji z aspartansko kislino pa se toksični učinek formaldehida še poveča. Metanol je specifično toksičen do optičnih živcev in je znano, da povzroča slepoto.

Zdravje

Aspartam je povzročitelj več kot 75 % negativnih reakcij, ki so bile v obdobju med letoma 1981 in 1995 prijavljene na FDA. Zabeleženih je 92 stranskih učinkov, ki so jih prijavili zdravniki in uporabniki, najpogostejši med njimi pa so: glavobol, migrena, vrtoglavica, izguba zavesti, slabost, nespečnost, težave z vidom in sluhom, težave z dihanjem, piskanje v ušesih, utrujenost, povečanje telesne teže, krči v mišicah, oteženo pomnjenje in razne čustvene motnje (depresija, razdražljivost, napadi panike ...) Prav tako pa naj bi uživanje aspartama lahko spodbudilo ali poslabšalo kronične bolezni, kot so tumor na možganih, multipla skleroza, epilepsija, sindrom kronične utrujenosti, Parkinsonovo in Alzeimerjevo bolezen in duševno zaostalost. Aspartama ne smejo uživati nosečnice, saj lahko povzroči razne deformacije pri plodu.

American Airforce piloti so dobili navodila, naj ne pijejo lahkih gaziranih pijač, ker zaradi vsebnosti aspartama vplivajo na njihovo sposobnost letenja.

Veliko pilotov je "padlo" na obveznem letnem testiranju, prav v povezavi z aspartamom.

 

Gradiva je precej, tudi o zelo spornem postopku odobritve aditiva s strani FDA..

prilagam še enega izmed mnogih člankov v angleščini

 

 

THE BITTER TRUTH ABOUT ASPARTAME AND NEOTAME"Aspartame/Neotame - the most dangerous substances in our food supply today." - Mary Nash Stoddard[Founder ACSN & Pilot Hotline]

Illegal Actions Gained FDA Approval:FDA approved the new genetically engineered molecule in 1974, following a spate of criminal acts committed by G.D. Searle pharmaceutical employees and contractors. That approval was rescinded before aspartame got to market, because it was revealed a component of aspartame [diketopiperazine] caused brain tumors. Tests were "falsified." Second approval occurred in 1981 under President Reagan's new FDA Director, Dr. Arthur H. Hayes. In 1983, Hayes' office approved the new molecule for aqueous solution [soft drinks, etc.] and three months later, Dr. Hayes left government, went to work for the NutraSweet public relations firm, Burson Marsteller for $1,000 a day. Hayes continues to craftily dodged all media requests for interviews on the topic. In fact, many government officials connected with this issue have defected - going to work for the industry whose products they were entrusted to approve or reject.In the laboratory, aspartame produced:* Brain Tumors* Breast Tumors* Uterine Tumors* Pancreatic Tumors* Seizures* DeathsThese went unreported, as did the deaths and seizures of other animals in the original tests. Tumors were removed then animals put back in test as tumor free, animals who died were brought back to life on paper when results officially submitted by G.D. Searle pharmaceutical to FDA.Aspartame changes DNA:In tests, the third generation of pups born to animals fed aspartic acid [component of aspartame] were born:

  1. Morbidly obese and
  2. Sexually DysfunctionalComponents of aspartame and its breakdown products can adversely affect the brains and central nervous systems of children and adults who consume it.

"When you harm the brain, you harm the very expression of one's self." - Peter Breggin, M.D. [Psychiatrist - Bethesda, MD]Reported psychological symptoms:* Suicidal Depressions* Panic Attacks and Anxiety [PAD] - Manias* Sleep Disorders* Severe Mood Disorders [rages, mood swings]* Brain Chemical Imbalance* Brain Wave Malfunctions [shows up in EEGs]* Personality Disorders* Hallucinations* Aberrant Behaviors

Medicine In Our Food?

Aspartame Components & Breakdown Products:Phenylalanine 50% - Lowers the seizure threshold. Causes mental retardation in some. Blocks production of serotonin [key neurotransmitter which controls: Moods / Sleep Patterns / Satiety ] Cultured in e-coli bacteria in the lab.Aspartic Acid 40% - Caused lesions or holes in the brains of lab animals. Neuroexcitatory [excites brain cells to death] amino acid. Causes motor-neuronal disorders in studies.Methanol 10% - Also known as "methyl alcohol", "moonshine", "Sterno." Damages the liver and eye. Two teaspoons can be lethal to humans. [Not processed the same in humans and animals, so lab tests do not show full impact of toxicity] Breaks down into formaldehyde [embalming fluid] and formic acid [venom in insect stings] at temperatures exceeding 86 degrees Fahrenheit. [Body temperature is 98.6 F] Implicated in birth defects and fetal alcohol syndrome in newborn infants. As a constituent of other foods in nature, it is found in combination with ethyl alcohol, which counteracts or neutralizes the toxic affects of methanol as it is metabolized by the body. There is no ethyl alcohol in aspartame, therefore methanol in aspartame is in "free form" and is immediately absorbed into the bloodstream. For every molecule of aspartame, there is a molecule of methanol released. Classic signs of methanol poisoning include: lethargy, confusion, leg cramps, back pain, severe headache, abdominal pain, slurred speech, fainting, visual loss/blindness, labored breathing.Diketopiperazine [DKP] - Caused brain tumors in laboratory tests. Thirteen out of 320 lab animals developed brain tumors in testing. Aspartame breakdown products cross the blood brain barrier to damage the brain.Aspartame is known to exacerbate or trigger onset of the following medical conditions:* Epilepsy* Parkinson's* Alzheimer's* Multiple Sclerosis* Chronic Fatigue Syn.* Lymphoma* Fibromyalgia / Eosinophilia Myalgia* Mental Retardation / Birth Defects* Diabetes / Hypoglycemia* Graves Disease* Heart Disease* Lung Disease* Liver Disease* Kidney Disease* Brain Tumors [astrocytoma/glioblastoma]* Pancreatic Disease* Kidney / Adrenal Disease* Arthritis* Blindness* Tinnitus* PMS* Carpal Tunnel* Lyme Disease* Muniere's Disease* Other: Rare / Hard to diagnose disorders[Aspartame has been called a "systemic" toxin - which means it may virtually adversely affect the function of every organ of the body. The effects are "cumulative" and do not show up in short term testing.]Aspartame and the Media:1990, The Guardian [London newspaper] was sued for publishing headline story - "NutraSweet Faked Tests to Get Sweetener Approved." Later settled out of court. NutraSweet sent intimidating press releases to all U.S. media warning they were suing.Documented instances are on record where the manufacturers of aspartame, threatened to sue and/or withdraw advertising dollars, from media. Health care professionals, scientists and medical schools have been "bribed" or intimidated into silence.Aspartame and Flying Safety:Many military, general aviation and commercial airline pilots have lost medical certification to fly based on seizures which occurred while they were ingesting aspartame. Grand mal seizures have been reported in flight in the cockpits of commercial airliners. A pilots' hotline in Dallas,TX was established by ACSN, in 1988 for the anonymous reporting of adverse reactions and safety-of-flight incidents. USAF Flying Safety magazine published warnings re: aspartame use by pilots. Pilot's publications around the globe have warned readers. The FAA will not send out an official memo - because the FDA refuses to recall aspartame as a safety hazard to consumers. Is aspartame the unacknowledged "terrorist" in every cockpit on every flight?Legal:ACSN co-founders Turner & Stoddard have both qualified in court as medical Expert Witnesses. Many consumer lawsuits have been dropped or settled out of court since the mid-eighties. The Washington D.C. Supreme Court refused to hear a case brought against the FDA by James Turner, Esq. Aspartame is illegal because it violated The Delaney Clause, which states no substance can be approved that is shown to cause cancer.In 1995, a stealth law crept across the land, which made it illegal to say anything disparaging about a perishable food product -example: yogurt sweetened with aspartame. Oprah was later sued under this law. [Agricultural Defamation Act]In 1985, G.D. Searle and NutraSweet Co. became wholly-owned subsidiaries of Monsanto Chemical in St. Louis. Controversial Supreme Court Judge, Clarence Thomas is a former Monsanto attorney.Monsanto sold their sweetener divisions to current owner, the J.W. Childs Partnership.1998, Monsanto applied for FDA approval for a monster molecule, "based on the aspartame formula" with one addition: 3-dimethylbutyl [listed on EPA's most hazardous chemical list]. Thus, Neotame becomes 13,000 times sweeter than sugar.July 5, 2002 - Neotame, Monsanto's super bio-manipulated molecule [newest fake sweetener] was approved by FDA over formally registered objections of the Aspartame Consumer Safety Network and others. Long term effects on humans are unknown.Aspartame is in over-the-counter drugs like: Tums, Pepsid AC, Metamucil, Alka Seltzer Plus, tooth whiteners, breath mints/strips and more.Diabetes and Aspartame / Neotame:Diabetics are most insidiously harmed , because they are told aspartame is their "life line" to good health, when, in fact, just the opposite is true. Remember, aspartame caused pancreatic tumors in the lab. A diabetic may see the real life effects of aspartame on blood sugar by performing this simple test with a finger-stick test kit:* Confirm blood sugar levels to be well within normal limits. If they are, then continue. Drink 2-3 cans [or the bottled equivalent] of Diet Soda containing aspartame, without stopping. Then, begin to retest for blood sugar level readings approximately one hour later. In this way, the adverse effects on blood sugar levels may be proven. This test is NOT recommended for anyone except individuals who already drink more than 2 diet drinks per day.The American Diabetic Association and The American Dietetic Association [Registered Dietitians] have been "bought out" by the sweetener manufacturers. [ACSN has proof!Parents the FDA does not protect your children.Greed and avarice have made government officials, industry and mainstream science, turn a deaf ear to the truth. Children are at least 4 times more susceptible to aspartame toxicity because of the developing central nervous system. Read labels. If it says:"phenylalanine" don't buy it. Insist your child's pediatric medical records contain this warning - "Never prescribe any medications containing phenylalanine [always present in aspartame and neotame]." Aspartame is a multi-billion dollar a year industry in more than 7,000 food products, chewing gums, children's antibiotics and meds, children's vitamins and pain medications for kids. In the lab, aspartame caused tragic birth defects.Action Agenda:* Copy and distribute this Fact Sheet to everyone. * Post this brochure on the Internet. ------->>>>> WE DID!!!* Tell everyone about this problem.------->>>>> WE DO!!!* Ask the next 5 people you see using aspartame if they have had any of the symptoms.* Get off the substance for a period of 4-6 weeks to see your physical and mental condition improve.* If you have sought medical treatment for any of these symptoms and you are/were an aspartame user - have your doctor enter into your official medical record that you believe aspartame may have caused some or all of your symptoms and that you are ceasing use of the sweetener and want to be "monitored" by your health care team as you get better. Very important.* Join over 10,000 concerned consumer members of Aspartame Consumer Safety Network worldwide who are fighting this battle to educate the consuming public about artificial sweeteners that masquerade as "natural."* Take all aspartame products back to the store and exchange them for healthy "real" food. This sends a message back to the manufacturer that we will no longer tolerate neurotoxins in our foods and children's items. Register a powerful complaint where it counts.* Write letters to the FDA and food manufacturers who use aspartame. Copy the editor of your local newspaper, stating your displeasure about the conspiracy of silence and illicit cover up of the facts by government and industry.The tobacco industry got away with it far too long. Let us learn a lesson from that and vow not to repeat mistakes that let them get away with it. The "real villains" in today's society are those who poison our food supply and that of our children - for profit.____________________________________Published by:Aspartame Consumer Safety NetworkMary Nash Stoddard, Founder and PresidentP.O.

Sama se jima že dolgo izogibam kar se le da. Vsaj poskušam v mojih zmožnostih in skromnem znanju. Tudi pri kupovanju artiklov za celo družino. Žal pa je prav aspartam tudi v artiklih, za katere sploh ne bi pomislili, recimo zobna pasta in se skriva, kot je že v članku omenjeno, pod mnogimi imeni.

Navedeno pismo je organizacija Media Awareness Network pred nekaj leti uporabila kot zgled v priročniku "Kako preveriti kredibilnost internetnih strani" (ali, bolj po domače povedano "Kako uporabljati tisto sivo gobico med ušesi"). Gre za skupek direktnih laži (na primer tista o pilotih; prav tako nobena od raziskav ni potrdila vpliva aspartama na nastanek katerekoli omenjene bolezni), psevdoznanosti (v dovolj velikih količinah je strupena tako voda kot tudi kuhinjska sol) in popolnih neumnosti (aspartam kot dodatek pijači ne more "razpasti" v diketopiperazin, ker je to encimska reakcija v živih organizmih). Skratka, gre samo za eno od zastraševalnih urbanih legend (živo srebro v cepivih, azbest v tamponih, halucinogeni v pitni vodi, svinec in ostale težke kovine v šminkah, računalniški virusi, ki bodo izbrisali trdi disk in povzročili, da bo računalnik eksplodiral na delovni mizi), ki jih je bilo včasih bolj zamudno razpečevati kot danes (treba jih je bilo nositi v fotokopirnico ali pretipkavati na karbonskih kopijah v pisalnih strojih, polniti kuverte in pisati naslove), dandanes pa zadošča samo en pritisk Send in že se nepreverjena neumnost znajde v tisočih internetnih predalih oziroma smeti forume. Kadarkoli dobite kaj takega v poštni predal, imejte toliko vesti, da pred nadaljnjim razpečevanjem vsaj toliko pogooglate, da vidite, ali gre za nateg (hoax) oziroma urbano legendo (kar bo po moji oceni držalo vsaj v 499 primerih od 500). lp, proxima

Proxima, z vsem spoštovanjem - kje je merilo, da presodiš, kaj je laž oz nateg in kje je nekaj resnice. Tole je eden izmed številnih člankov zelo različnih avtorjev. njihova imena sem poguglala in so zaposleni v institucijah, katere so delale raziskave v zvezi z aspartamom. Tam so objavljeni tuidi izsledki raziskav. Tega je ogromno, oz. toliko, da se ne morem slepiti.

Enostavno dvomim, da bi imelo toliko različnih ljudi čas in voljo, peljati gonjo proti nekemu aditivu, in pri temu nebi imeli nič od tega. Nasprotno ima proizvajalec ogromno od tega...

Mimogrede, aspratam razpade v organizmu.

Proxima Robida, najbrž je merilo presoje še vedno znanstveni članek, ki je objavljen v znnstveni reviji in gre čez nekaj cenzure. Saj veš, da je današnji čas podrejen marketingu, verjemi, veliko ljudi živi zelo dobro zaradi gonje proti različnim stvarem. Sicer je to samo moje mišljenje, ampak zakaj vsak dan nekdo ne objavi kaj o nikotinu, ki je strup, recimo. Potrjeno... in ravno tako ga ljudje konzumirajo. Bo že bolje, lep dan! Mateja

Merila so objave in citati v strokovni literaturi, peer-review in statistična kredibilnost, kar grem preverjat na Medscape, BMJ, NCCN in podobna mesta. In vedno se čudim, kako zelo se ljudje trudijo verjeti podobnim paranoidnim konstruktom, na vso moč se pa izogibajo prometnim predpisom ali preventivnim pregledom, kar bi - za razliko od podobnih mailov - utegnilo zares vplivati na preživetje. lp, proxima

Seveda, in to eden od bolj zahrbtnih. NCCN, ki sem ga imela jaz v mislih, pomeni National Comprehensive Cancer Network (enkrat, ko bo čas, bom povedala zgodbo o Nixonu in NCCN), ki ga na internetu najdemo pod URL oznako http://www.nccn.ORG - za razliko od strani, ki jo navajaš ti (http://www.nccn.NET), ki nima z originalnim NCCN nič skupnega, le da podobnost internetnega naslova zlorablja za zavajanje neukega ljudstva. lp, proxima

Če pogledamo strukturo aspartama je očitno, da je dipeptid fenilalanina in asparaginske kisline, ki ima karboksilno skupino fenilalanina zaestreno z metanolom. Edina toksična komponenta je metanol. In glede na to, da v kislem (želodec) apartam razapde na metanol in dipeptid, ga najbrž res ni dobro uživati v večjih količinah. Ampak, če je res 180X slajši od sladkorja, je najbrž v izdelkih prisoten v zelo majhnih koncentracijah. Aminokislini, ki nastaneta iz dipeptida, pa tako ali tako vsakodnevno dobivamo tudi z drugo hrano. Zato res ne razumem zakaj naj bi bil aspartam tako zelo strupen. Da pa je bolje uživati domačo, naravno hrano pa tako ali tako že vsak ve. rozi13

Thank you, Proxima!

 

Mi bi morali biti vekom vekov pod rušo, ker uporabljam sladila v kar precejšnji meri že 25 let. Sploh, odkar se s splendo (in očitno z Natreenom) lepo peče.
