      metabolic syndrome is tied to diet soda, PL Lutsey, LM Steffen,

      Murray 2008.02.07

      "But the one-third who ate the most fried food increased their risk
      by 25 percent, compared with the one-third who ate the least, and
      surprisingly, the risk of developing metabolic syndrome was 34
      percent higher among those who drank one can of diet soda a day
      compared with those who drank none.

      "This is interesting," said Lyn M. Steffen, an associate professor of
      epidemiology at the University of Minnesota and a co-author of the
      paper, which was posted online in the journal Circulation on Jan. 22.
      "Why is it happening? Is it some kind of chemical in the diet soda,
      or something about the behavior of diet soda drinkers?""

      "The diet soda association was not hypothesized
      and deserves further study."

      Aspartame: a safety evaluation based on current use levels,
      regulations, and toxicological and epidemiological studies.
      Magnuson BA, Burdock GA, Doull J, Kroes RM, Marsh GM,
      Pariza MW, Spencer PS, Waddell WJ, Walker R, Williams GM.
      Burdock Group, Washington, DC, USA. bmagnuso@...;

      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
      dministration 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.
      [ Humans are about ten times more vulnerable to methanol
      (formaldehyde) toxicity than any animal. ]

      Critical review of all carcinogenicity studies conducted on
      aspartame found no credible evidence that aspartame is
      carcinogenic.

      re two Ramazzini Foundation cancer studies 2007.06.25: Murray 2007.07.18 ]

      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.

      harriett.h.butchko@...;

      Over 20 years have elapsed since aspartame was approved by
      regulatory agencies as a sweetener and flavor enhancer.

      The safety of aspartame and its metabolic constituents was
      established through extensive toxicology studies in laboratory
      animals, using much greater doses than people could possibly
      consume.

      Its safety was further confirmed through studies in several human
      subpopulations, including healthy infants, children, adolescents,
      and adults; obese individuals; diabetics; lactating women; and
      individuals heterozygous (PKUH) for the genetic disease
      phenylketonuria (PKU) who have a decreased ability to metabolize
      the essential amino acid, phenylalanine.

      Several scientific issues continued to be raised after approval,
      largely as a concern for theoretical toxicity from its metabolic
      components -- the amino acids, aspartate and phenylalanine,
      and methanol -- even though dietary exposure to these components
      is much greater than from aspartame.

      Nonetheless, additional research, including evaluations of possible
      associations between aspartame and headaches, seizures, behavior,
      cognition, and mood as well as allergic-type reactions and use by
      potentially sensitive subpopulations, has continued after approval.

      These findings are reviewed here.

      The safety testing of aspartame has gone well beyond that required
      to evaluate the safety of a food additive.

      When all the research on aspartame, including evaluations in both
      the premarketing and postmarketing periods, is examined as a
      whole, it is clear that aspartame is safe, and there are no unresolved
      questions regarding its safety under conditions of intended use.

      ASE "6.3.1. Two-Year Bioassay Studies

      Aspartame was first approved by FDA as a nonnutritive sweetener
      in 1974, based on the toxicity studies that were conducted by
      the Searle Laboratories.

      Chronic toxicity studies with aspartame, and its decomposition
      product, DKP, were conducted in mice, rats, and dogs.

      A 46-week study with aspartame was also performed with hamsters.

      Table 15 provides a summary of these studies.

      The carcinogenic potential of these compounds is discussed
      in the next sections.

      Following the approval of aspartame, a formal objection was
      submitted to the FDA (FDA, 1981) questioning the conclusions
      from the rodent studies on aspartame conducted by Searle, and
      proposing that aspartame may have the potential to cause brain tumors
      in humans.

      This objection resulted in FDA staying the regulation approving
      the marketing of aspartame in 1975, and the establishment of a
      Public Board of Inquiry to reexamine the studies submitted by
      Searle to the FDA.

      Prior to the evaluation by the Board, the 15 studies submitted by
      Searle were thoroughly audited by the Universities Associated for
      Research and Education in Pathology, Inc. (UAREP)
      and by the FDA.

      The findings of the UAREP, the FDA,
      and the Public Board of Inquiry were considered and evaluated
      by the Commissioner of Food and Drugs, resulting in the issuance
      of the commissioner's Final Decision that at projected levels
      of consumption, aspartame would not pose a risk of brain damage
      and will not cause brain tumors (FDA docket, 75F-0355, 1981)
      (FDA, 1981).

      This decision resulted in FDA vacating the stay of the original
      1974 regulation.

      Objections to the of the use of aspartame were again filed with the
      FDA in 1983; however, the regulations approving the use of
      aspartame was not stayed following these objections, as the
      FDA stated that they failed to create sufficient doubt
      about the safety of aspartame.

      A response to the objections and a denial for a hearing was issued in
      1984 by the Acting Commissioner of Food and Drugs (FDA docket
      75F-0355 and 82F-0305) (FDA, 1984; Wurtman and Maher, 1987). "


      [ In fact the FDA brought suit against Searle for its radically biased,
      improper scientific studies.

      The industry won by persuading the FDA's two attorneys to let
      the legal process languish.

      Soon, the attorneys inexplicably found peasant, prosperous futures
      in the industry's networks.

      Similar adroit exercises in corporate realpolitik were led by the CEO
      of Searle, none other than that modest American hero,
      Donald Rumsfeld, who used Reagan's victory to immediately
      manipulate the FDA's approval by a brand new Commisioner,
      Arthur Hull Hayes, in July, 1981, of aspartame in dry foods,
      and then in beverages two years later, whereupon the fortunate Commissioner,
      troubled by hints of political corruption, found
      a gracious post with the industry's PR agency.

      Industry-funded study calls aspartame safe
      Tue Sep 11, 2007 10:58PM EDT
      By Will Dunham

      WASHINGTON (Reuters) - A review of 500 studies conducted
      over a quarter century has turned up no credible evidence that the
      widely used artificial sweetener aspartame is unsafe, industry-funded
      research released on Tuesday showed.

      A panel of American, British and Dutch experts rejected the notion
      that aspartame causes cancer, seizures, neurological damage or
      learning problems, or contributes to obesity.

      The panel did conclude that some people might be prone to
      headaches after consuming it.

      The group did not conduct original research but assessed existing
      studies on the safety of aspartame, first approved by the U.S.
      Food and Drug Administration in 1981. It is widely used in diet
      soft drinks and sold in packets for use in coffee, tea or on food.

      The panel saw consumption of it increasing, but called it safe for
      adults or children and even among the heaviest users.

      "Controlled and thorough scientific studies confirm aspartame's
      safety and find no credible link between consumption of aspartame
      at levels found in the human diet and conditions related to the nervous
      system and behavior, nor any other symptom or illness,"
      the researchers said in a paper published in the journal
      Critical Reviews in Toxicology.

      "There is no credible evidence that aspartame is carcinogenic,"
      they added.

      Michael F. Jacobson, PhD, executive director of the consumer group
      Center for Science in the Public Interest, said the study grossly
      exaggerates the importance of studies doubting health risks while
      rejecting studies identifying possible problems.

      Jacobson said "clouds of doubt" linger about aspartame's safety
      and said it would be wise to minimize consumption of it until the
      research is definitive. "This review is totally unreliable and people
      should simply ignore it," Jacobson said.

      Since its approval, some people have argued that aspartame can
      cause a variety of illnesses, and various Web sites such as
      www.sweetpoison.com denounce the sweetener.

      ITALIAN FINDINGS

      The researchers rejected the findings of a study published in June
      by Italian scientists that showed aspartame might cause leukemia,
      lymphoma and breast cancer in rats. University of Maryland food
      and nutrition professor Bernadene Magnuson said that study was undermined by
      "numerous methodological and interpretation errors."

      The FDA said after that study was published that it saw no reason
      to alter its view that aspartame is safe.

      Magnuson said one possible area of concern was research
      indicating some may get headaches after consuming aspartame.
      Magnuson cited conflicting results in headache studies, but said that
      "a small subset of the population" may have some sensitivity to
      aspartame-induced headaches.

      The panel reviewed more than 500 human and animal studies,
      articles and reports performed in the past 25 years.

      "Certainly it is one of the most studied compounds ever," panel
      chairman Dr. William Waddell of the University of Louisville
      told reporters, saying the panel's 98-page report should put to rest
      safety concerns relating to aspartame.

      The panel's work was funded by Japanese food and seasonings giant
      Ajinomoto Co, a maker of aspartame. Magnuson said the company
      had no control over who was on the panel or how their work was
      done, and panel members did not know who was funding the work
      until it was done.

      "I have no qualms in terms of who funded the study," Magnuson
      told reporters.

      Aspartame is used in more than 6,000 food products worldwide.

      Merisant Co is another leading aspartame company, with the brands
      Equal, Canderel and NutraSweet.

      Professional Interests:

      The research in Dr. Williams' laboratory focuses on mechanisms
      of chemical carcinogenesis and procedures for identifying chemical
      carcinogens.
      Investigations are being pursued on the pathogenesis of liver cancer
      induced either by agents that attack DNA or that operate through
      indirect or epigenetic mechanisms.
      Aspects of particular interest are the shapes of dose-response
      curves for these two types of agents, and the identification of
      thresholds for cellular effects.
      The laboratory has a major project on interaction between ultraviolet
      irradiation and chemicals to produce photochemical mutagenicity and
      carcinogenicity.
      In studying procedures for identifying chemical carcinogens, emphasis
      has been placed on techniques for measuring interaction with DNA to
      detect genotoxic agents.
      Also under investigation are methods for inhibiting chemical-induced
      carcinogenicity.
