Aspartame and sugar Alternatives

What is Wrong with White Sugar?
  • Refined white sugar has been linked to dental
    cavities, increased cholesterol levels, heart
    disease, hypoglycemia, diabetes, obesity,
    osteoporosis and nutritional deficiencies.
  • Can create dramatic fluctuations in blood sugar
    which, over time, can wear down both the pancreas
    and the adrenal glands.
  • Because it provides no nutrition, most dietitians
    agree that white sugar has no legitimate place in
    a healthy diet.

3
Manufacturing of Table Sugar
  • Modern sugar cane farming, chemical fertilizers
    and pesticides are used to grow the sugar cane
    plants.
  • The mature sugar cane is harvested and sent to
    refining factories, where the cane's vitamins,
    minerals and other nutrients are separated from
    the sucrose.
  • After further refining, the cane juice is dried,
    processed into crystals and bleached to remove
    its naturally dark color.

4
What is Aspartame?
  • Aspartame is a low-calorie sweetening ingredient
    that provides the sweet taste of sugar without
    the calories. Aspartame has been used in numerous
    foods and beverages for more than 20 years and is
    enjoyed by millions of Americans every day.

5
Where Can Aspartame be Found?
  • Aspartame is used to sweeten products such as
    low-calorie tabletop sweeteners, carbonated soft
    drinks, powdered soft drinks, puddings, gelatins,
    frozen desserts, yogurt, hot cocoa mixes, teas,
    breath mints, chewing gum and other foods, as
    well as some vitamin and cold preparations.

6
Acceptable Levels of Aspartame
  • 50 mg / kg of body weight
  • Average aspartame Contents of Selected foods

7
History of Aspartame
  • Aspartame was discovered in 1965 by a researcher,
    Mr. James Schlatter, at G.D. Searle Company.
  • Schlatter was a scientist doing research with
    amino acids, working to develop a treatment for
    ulcers. In 1965, while creating a bioassay, an
    intermediate chemical was synthesized --
    aspartylphenylalanine-methyl-ester (aspartame).
    In December of 1965, while James Schlatter was
    recrystalling aspartame from ethanol, the mixture
    spilled onto the outside of the flask. Some of
    the powder got onto his fingers. Later, when he
    licked his fingers to pick up a piece of paper,
    he noticed a very strong sweet taste.
  • Since that time aspartame has become one of the
    most highly valued and widely used sweeteners in
    the world, known for its clean taste and amazing
    sweetness (180-200 times sweeter than sucrose).
    Aspartame also quickly became a highly valued
    ingredient among people with diabetes because it
    literally changed their lives, allowing them to
    enjoy foods that are sweet and tasty without
    ingesting sugar.

8
How is Aspartame Handled by the Body?
  • Aspartame is broken down in the body to the amino
    acids aspartic acid and phenylalanine as well as
    a small amount of methanol. It is a mixture of 40
    percent aspartic acid, 50 percent of
    phenylalanine, and 10 percent of methanol.
  • These components are also found naturally in
    foods such as meats, milk, fruits and vegetables.
  • The body uses these components in exactly the
    same way whether they come from aspartame or
    common foods.
  • In fact, the foods you consume every day provide
    much greater amounts of these components than
    does aspartame

9
The Molecular Structure of Aspartame
10
Methanol and its Break Down in our Body
  • Methanol (methyl alcohol or wood alcohol) is a
    colorless, poisonous, and flammable liquid. It is
    used for making formaldehyde, acetic acid, methyl
    t-butyl ether (a gasoline additive), paint
    strippers, carburetor cleaners for your car's
    engine, and chloromethanes, et al. This poison
    can be inhaled from vapors, absorbed through the
    skin, and ingested.
  • Methanol is the type of alcohol you read about
    when people become blind from drinking it. In
    aspartame, methanol poisoning and poisoning from
    methanol's breakdown components (formaldehyde and
    formic acid) can have widespread and devastating
    effects. This occurs in even small amounts, and
    is especially damaging when introduced with
    toxic, free-form amino acids, called
    excitotoxins.
  • Methanol is quickly absorbed through the stomach
    and small intestine mucosa. The methanol is
    converted into formaldehyde (a known carcinogen).
    Then, via aldehyde hydrogenase, the formaldehyde
    is converted to formic acid. These two
    metabolites of methanol are toxic and cumulative.

11
Phenylalanine and its Breakdown in our Body
  • Phenylalanine is an amino acid. Well, amino acids
    are good for us, right? Don't they keep us
    healthy? The answer is yes, amino acids are
    necessary for good health, EXCEPT when you
    separate the individual amino acid from its
    protein chain, and use it as an "isolate" or by
    itself.

12
Aspartic Acid and its Breakdown in our Body
  • The Aspartic acid, in aspartame, is also an
    excitotoxin. An excitotoxin, is a deleterious
    substance that excites or over-stimulates nerve
    cells. This occurs in the brain, as well as the
    peripheral nerves, because aspartic acid, in free
    form, is an absorption accelerant easily
    crosses the blood-brain barrier.
  • This pathological excitation of nerve cells
    creates a breakdown of nerve function, as we will
    see. Basically, they are a group of compounds
    that can cause special neurons within the nervous
    system to become overexcited to the point that
    these cells will die.
  • That's right, they are excited to death.
    Excitotoxins include such things as monosodium
    glutamate (MSG), aspartate, (a main ingredient in
    NutraSweet), L-cysteine (found in hydrolyzed
    vegetable protein) and related compounds.

13
Studies and Experimental Data
  • G.D. Searle approached Dr. Harry Waisman,
    Biochemist, Professor of Pediatrics, Director of
    the University of Wisconsin's Joseph P. Kennedy
    Jr. Memorial Laboratory of Mental Retardation
    Research and a respected expert in phenylalanine
    toxicity, to conduct a study of the effects of
    aspartame on primates. The study was initiated on
    January 15, 1970 and was terminated on or about
    April 25, 1971.
  • Seven infant monkeys were given aspartame with
    milk. One died after 300 days. Five others (out
    of seven total) had grad mal seizures. The actual
    results were hidden from the FDA when G.D. Searle
    submitted its initial applications.
  • Neuroscientist and researcher John W. Olney found
    that oral intake of glutamate, aspartate and
    cysteine, all excitotoxic amino acids, cause
    brain damage in mice (Olney 1970). Dr. John W.
    Olney informed G.D. Searle that aspartic acid
    caused holes in the brains of mice.
  • Ann Reynolds, a researcher who was hired by G.D.
    Searle and who has done research for the
    Glutamate (MSG) Association, and was asked to
    confirm Dr. Olney's tests. Dr. Reynolds confirmed
    aspartame's neurotoxicity in infant mice.
  • Excitotoxic compounds like MSG, aspartate,
    cysteine seem to create hypothalamic lesions,
    particularly in young animals. The reason for the
    latter is likely the fact that the blood brain
    barrier closes most slowly (if ever completely)
    around structures like hypothalamus. The outcome
    for such animals (rats) was obesity,severe
    behavioral changes, etc.

14
By H. J. Roberts, M.D., F.A.C.P., F.C.C.P.
  • Every patient with unresolved neurologic,
    psychologic, allergic, dermatologic,
    gastrointestinal and metabolic/endocrine problems
    should be queried about aspartame intake.
  • The diagnosis of multiple sclerosis should be
    deferred pending at least several months
    observation in the case of persons consuming
    aspartame.
  • A pregnant woman should not risk the health of
    her fetus by consuming aspartame products.
  • Visual, neurologic or bowel problems in diabetics
    should not be ascribed to a presumed underlying
    retinopathy or neuropathy until evaluating the
    response to aspartame abstinence.
  • Cataract surgery ought to be deferred in heavy
    aspartame users to evaluate for spontaneous
    improvement after abstinence.
  • Patients presenting with seizures, headache,
    atypical facial or eye pain, the Meniere
    syndrome, depression, the carpal tunnel syndrome,
    normal-pressure hydrocephalus, and a host of
    other unexplained neuropsychiatric problems, or
    who fail to respond to conventional treatment,
    must be queried about aspartame use especially
    if invasive studies are planned.
  • Young adults who express concern about "possibly
    having early Alzheimer's disease," based on
    recent confusion and memory loss, ought to be
    observed at least one month after stopping
    aspartame before this diagnosis is pursued.
  • Gynecologic surgical procedures to evaluate gross
    menstrual changes should be deferred pending the
    response to abstinence.

15
Aspartame Versus Table Sugar
  • A can of soft drink sweetened with sugar contains
    about 150 Calories, compared to only one or two
    Calories in a can of soft drink sweetened with
    aspartame.
  • since it is sugar-free, aspartame can make an
    important contribution to good dental health.
  • For people on the Atkins Diet, aspartame is ideal
    as it is does not contain any carbohydrates
  • When aspartame-containing beverages are left at
    high storage temperatures, the aspartame can
    degrade and form small amounts of methanol.
  • Diketopiperazine (DKP) is another breakdown
    product of aspartame.
  • One small study (which has not been repeated) did
    find some worsening of depression when depressed
    patients took large doses of aspartame
  • It has not been shown to be dangerous to
    diabetics in any way, where as sugar has.

16
Aspartame Versus Table Sugar
  • Aspartame products have been shown to not satisfy
    cravings as well as regular sugar products
  • Overweight subjects who consumed fairly large
    amounts of sucrose (28 of energy) mostly as
    beverages, had increased energy intake, body
    weight, fat mass and blood pressure after 10 wk.
    These effects were not observed in a similar
    group of subjects who consumed artificial
    sweeteners.

17
Is Aspartame Safe?
  • Yes. Aspartame's safety has been documented in
    more than 200 objective scientific studies.
  • The safety of aspartame has been confirmed by the
    regulatory authorities in more than 100
    countries, including the U.S. Food and Drug
    Administration, Health Canada, and the European
    Commission's Scientific Committee on Food, as
    well as by experts with the United Nations' Food
    and Agriculture Organization and World Health
    Organization.

18
Benefits of Aspartame
  • Aspartame offers people with type 1 and type 2
    diabetes greater variety and flexibility in
    budgeting their total carbohydrate intake and
    helps them satisfy their taste for sweets without
    affecting blood sugar.
  • People with diabetes are more likely to stick
    with a healthful meal plan when they can include
    foods they enjoy.
  • Consuming products with aspartame can reduce
    calories, which helps people with diabetes manage
    their weight.

19
Risks Associated with Aspartame
  • Individuals with the rare genetic disease,
    phenylketonuria (PKU), cannot properly metabolize
    phenylalanine.
  • (PKU) is detected at birth through a mandatory
    screening program, and these individuals must
    monitor their intake of phenylalanine from all
    foods including foods containing aspartame.

20
Other Natural Sugar Alternatives
  • Any refined sweetener, whether it's white sugar,
    honey or another variation, is broken down by the
    body into glucose, and is associated with the
    same problems, like weight gain and cavities.
    Even so, natural sweeteners have their
    advantages. Most are less refined than white
    sugar, have a slightly higher nutritional value,
    and tend to be broken down more slowly in the
    body, creating less impact on blood sugar.
    Following are some sweet substitutes to try
  • --Agave nectar. This liquid sweetener comes in
    light and dark varieties, and is a good
    substitute for corn syrup.
  • --Brown rice syrup. Brown rice syrup has a mildly
    sweet, delicate flavor and is processed by the
    body more slowly than white sugar.
  • --Date sugar. Made from ground dates, this pale
    brown sweetener makes an excellent substitute for
    brown sugar.
  • --Evaporated cane juice. Also called "milled
    cane" or "unrefined cane juice," this
    less-processed version of white sugar contains
    some vitamins and minerals, is unbleached and is
    available in organic versions.
  • --Fructose. This is available in both powdered
    and liquid versions. Fructose, which is plant
    sugar, releases glucose into the bloodstream more
    slowly than white sugar and this makes it more
    suitable for diabetics.
  • --Fruit juice concentrate. Made from apples,
    grapes, peaches, pears, pineapples, berries or
    other fruit, these sweeteners have the
    consistency of thick syrup and an intense flavor.
  • --Honey. Clover is the most common, but honey
    comes in dozens of varieties, depending on the
    flower that produces it. Look for raw,
    unpasteurized honey, which retains its beneficial
    enzymes and nutrients. Honey is also available
    powdered.
  • --Maple syrup. Nearly twice as sweet as white
    sugar, maple syrup adds rich flavor and trace
    minerals to nearly any recipe. Maple sugar is
    made by evaporating the liquid from maple syrup.
  • --Molasses. Molasses contains the nutrients
    extracted from sugar cane and sugar beets.
    Blackstrap molasses, from the bottom of the
    processing vats, is thick, dark and high in
    nutrients.
  • --Turbinado. Made from the initial pressing of
    the cane, turbinado contains molasses and has a
    sweet, rich flavor and blond color.

Economic Forces Behind Aspartame
  • Before aspartame received its final green light
    from the FDA for use in dry foods in 1981 and in
    beverages in 1983, scientists objected to its
    approval.
  • Initially granted FDA approval for use in dry
    foods in 1974, but was later blocked by
    objections raised by attorney James Turner and
    John Olney, M.D.
  • Investigators described aspartame safety studies
    conducted by G.D. Searle between 1967 and 1975 as
    shoddy science' and sloppy tests.' Ninety out
    of 113 aspartame safety tests showed
    discrepancies.
  • FDA scientists and outside researchers insisted
    that more rigorous and reliable testing was
    needed.
  • Despite these concerns, on July 18, 1981
    aspartame was approved for use in dry foods by
    FDA Commissioner Arthur Hull Hayes who,
    incredibly overruled his own Public Board of
    Inquiry which recommended that approval be
    denied. He also ignored the law, Section
    409(c)(3) of the Food Drug and Cosmetic Act (21
    U.S.C. 348), which says that a food additive
    should not be approved if tests are inconclusive

23
Economic Forces Cont
  • In 1981, John Olney, professor of psychiatry and
    neuropathology at Washington University, St.
    Louis cited risks involved with the use of
    aspartame.
  • Olney, who was instrumental in banning the use of
    cyclamates, warned that aspartame had brain
    damaging properties.
  • The American Academy of Pediatrics raised
    concerns about the effects of phenylalanine on
    PKU carriers who were unaware that they had the
    defect. Astonishingly, even the National Soft
    Drink Association had serious doubts about the
    safety of aspartame.
  • In 1983, the NSDA filed a 30-page objection to
    aspartame's use in beverages and then,
    inexplicably reversed its opposition. Aspartame
    received approval for use in soft drinks in 1983
    and shortly thereafter, Commissioner Arthur Hull
    Hayes left the FDA. He was then (allegedly) hired
    as a consultant (at the rate of 1,000 per day)
    with G.D. Searle's public relations firm.
  • As said by Senator Howard Metzenbaum We had
    better be sure that the questions that have been
    raised about the safety of this product are
    answered. I must say at the outset, this product
    was approved by the FDA in circumstances that can
    only be described as troubling.

24
Economic Forces Cont
  • Prompted by mounting safety concerns within the
    scientific community, Ohio Senator Howard
    Metzenbaum called for Senate hearings on
    NutraSweet.
  • Introduced the Aspartame Safety Act of 1985 on
    Aug. 1 of that year.
  • The bill called for clinical studies to ascertain
    the safety of aspartame, a moratorium on the
    introduction of aspartame into new products until
    independent testing was complete, labeling of
    products including the amount of aspartame in
    each serving and the allowable daily intake, and
    a warning that aspartame is not intended for
    infant use.
  • The bill also required the FDA to set up a
    clinical adverse reaction committee to collect
    reports of adverse effects and to send written
    notices to physicians about aspartame. In a March
    3, 1986 news release, the Senator stated "we
    cannot use American's children as guinea pigs to
    determine the safe' level of NutraSweet
    consumption." Sadly, the bill that potentially
    could have stopped an ongoing tragedy, was killed
    in the Labor and Human Resources Committee, and
    never reached the Senate floor.
  • After suffering a 28 million dollar loss in the
    previous year, G.D. Searle was bought by the
    chemical company, Monsanto in 1985. Monsanto then
    created the NutraSweet Company as a subsidiary,
    separate from G.D. Searle. Over the next decade,
    aspartame consumption soared and reports of ill
    side effects increased.
  • In June of 1996, FDA Commissioner Dr. David
    Kessler lifted all restrictions on the use of
    aspartame and granted it blanket approval,
    despite the fact that this neurotoxin (mislabeled
    as a food additive) is in reality, a dangerous
    drug that changes brain chemistry and interacts
    with other drugs. He did so without public
    notification. He also ignored a request by
    Senator Metzenbaum (then retired) to initiate
    additional safety testing. Aspartame could now be
    used as freely as sugar.

The Problem?
28
The Sweetest Advice?
  • Use "natural" sugar substitutes like honey and
    maple syrup in moderation, or stick to fruit to
    soothe your sweet tooth -- it's high in
    nutrients, phytochemicals and fiber, and is
    broken down more slowly than any kind of refined
    sugar.
  • Some ideas puree frozen berries with unsweetened
    rice milk for a fast breakfast smoothie, stew
    pears and currants in apple juice and cinnamon
    for a simple dessert, freeze bananas for a
    cooling summer snack, munch on grapes instead of
    candy.
