BIO Mary Nash Stoddard on Twitter

PRESENTING: MARY NASH STODDARD - Co-Founder of the massive international anti-aspartame movement in the mid 1980's, following the brain tumor death of her forty two year old husband, Mike. Ms. Stoddard suffered a life threatening aspartame-related blood disorder in 1985, whereupon, The NutraSweet Co. offered her an all-expense paid vacation for two anywhere in the world, if she would agree to be tested by their doctors. She declined, with the blessing of her doctor, and the rest is history. She has conducted multi-national lecture tours and is a popular visiting professor at colleges, universities and medical schools. "Deadly Deception - Story of Aspartame" is a toxicology sourcebook, edited by Ms. Stoddard, documenting the harmful effects of the world's most toxic artificial sweetener. The companion one hour "Deadly Deception" video is further documentation - taped at a prestigious scientific conference. Stoddard's efforts, over more than two decades, led to the present rejection of the sweetener by many of the food and beverage giants of industry, as they rush to distance themselves from the liabilities associated with use of a neuro-toxic substance in their products. She has testified in court as an Expert Medical Witness and like her counterpart, Erin Brokovitch, helped with a number of lawsuits on behalf of consumers. Her powerful message has reached millions around the world through the airwaves on radio and television, in print and through popular personal appearances.

CONSIDERED A DANGEROUS SUBSTANCE ACCORDING TO DIRECTIVE 67/548/EEC, POINT 4; AND HAZARDOUS ACCORDING TO OSHA 29 CFR 1910.1200 (USA). POTENTIAL HEALTH EFFECTS ACUTE HEALTH EFFECTS SWALLOWED Toxic effects may result from the accidental ingestion of the material; animal experiments indicate that ingestion of less than 40 gram may be fatal or may produce serious damage to the health of the individual. The material can produce chemical burns within the oral cavity and gastrointestinal tract following ingestion. EYE The material can produce chemical burns to the eye following direct contact. Vapours or mists may be extremely irritating. When applied to the eye(s) of animals, the material produces severe ocular lesions which are present twenty-four hours or more after instillation. SKIN Skin contact with the material may produce toxic effects; systemic effects may result following absorption. The material can produce chemical burns following direct contact with the skin. INHALED Toxic by inhalation. Evidence shows, or practical experience predicts, that the material produces irritation of the respiratory system in a substantial number of individuals following inhalation. CHRONIC HEALTH EFFECTS On the basis, primarily, of animal experiments, concern has been expressed that the material may produce carcinogenic or mutagenic effects; in respect of the available information, however, there presently exists inadequate data for making a satisfactory assessment. Limited evidence shows that inhalation of the material is capable of inducing a sensitisation reaction in a significant number of individuals at a greater frequency than would be expected from the response of a normal population. Pulmonary sensitisation, resulting in hyperactive airway dysfunction and pulmonary allergy may be accompanied by fatigue, malaise and aching. Significant symptoms of exposure may persist for extended periods, even after exposure ceases. Symptoms can be activated by a variety of nonspecific environmental stimuli such as automobile exhaust, perfumes and passive smoking. Practical experience shows that skin contact with the material is capable either of inducing a sensitisation reaction in a substantial number of individuals, and/or of producing a positive response in experimental animals. Principal routes of exposure are usually by inhalation of vapour and skin contact/absorption Sensitisation may give severe responses to very low levels of exposure, i.e. hypersensitivity. Sensitised persons should not be allowed to work in situations where exposure may occur. Prolonged or repeated skin contact may cause drying with cracking, irritation and possible dermatitis following. Minor but regular methanol exposures may effect the central nervous system, optic nerves and retinae. Symptoms may be delayed, with headache, fatigue, nausea, blurring of vision and double vision. FORMALDEHYDE. ChemWatch Material Safety Data Sheet (REVIEW) CHEMWATCH 64715 Issue Date: Fri 2-Jul-2004 CD 2004/3  Page 3 of 11 Section 3 - HAZARDS IDENTIFICATION ... or severe exposures may cause damage to optic nerves, which may become severe with permanent visual impairment even blindness resulting. WARNING: Methanol is only slowly eliminated from the body and should be regarded as a cumulative poison which cannot be made non-harmful [CCINFO] When administered by inhalation, formaldehyde induced squamous cell carcinomas of the nasal cavity in rats of both sexes. Although excess occurrence of a number of cancers has been reported, the evidence for a possible involvement of formaldehyde is strongest for nasal and nasopharangeal cancer. The occurrence of these cancers showed an exposure-response gradient in more than one study, but the numbers of exposed cases were often small and some studies did not show excesses 

Section 4 - FIRST AID MEASURES SWALLOWED Rinse mouth out with plenty of water. If poisoning occurs, contact a doctor or Poisons Information Centre. • If swallowed do NOT induce vomiting. • If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain open airway and prevent aspiration. • Immediately give a glass of water. EYE If this product comes in contact with the eyes: • Immediately hold eyelids apart and flush the eye continuously with running water. • Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and moving the eyelids by occasionally lifting the upper and lower lids. • Continue flushing until advised to stop by the Poisons Information Centre or a doctor, or for at least 15 minutes. • Transport to hospital or doctor without delay. • Removal of contact lenses after an eye injury should only be undertaken by skilled personnel. SKIN If skin or hair contact occurs: • Immediately flush body and clothes with large amounts of water, using safety shower if available. • Quickly remove all contaminated clothing, including footwear. • Wash skin and hair with running water. Continue flushing with water until advised to stop by the Poisons Information Centre. • Transport to hospital, or doctor.INHALED • If fumes or combustion products are inhaled remove from contaminated area. • Lay patient down. Keep warm and rested. • Prostheses such as false teeth, which may block airway, should be removed, where possible, prior to initiating first aid procedures. • Apply artificial respiration if not breathing, preferably with a demand valve resuscitator, bag-valve mask device, or pocket mask as trained. Perform CPR if necessary. • Transport to hospital, or doctor, without delay.

WARNING:

NOTES TO PHYSICIAN For acute or short-term repeated exposures to formaldehyde:

 INGESTION [as a breakdown product of methanol in aspartame] : 
• Patients present early with severe corrosion of the gastro-intestinal tract and systemic effects. 
• Inflammation and ulceration may progress to strictures.

Elimination half-life of methanol during hangover.
Jones AW.
Department of Forensic Toxicology, University Hospital, SE-581 85 Linkoping,
Sweden. wayne.jones@RMV.se
This paper reports the elimination half-life of methanol in human
volunteers. Experiments were made during the morning after the subjects had
consumed 1000-1500 ml red wine (9.5% w/v ethanol, 100 mg/l methanol)
the previous evening.  [  100 to 150 mg methanol ]
The washout of methanol from the body coincided with the onset of hangover.
The concentrations of ethanol and methanol in blood were determined
indirectly by analysis of end-expired alveolar air.
In the morning when blood-ethanol dropped below the Km of liver alcohol
dehydrogenase (ADH) of about 100 mg/l (2.2 mM), the disappearance half-life
of ethanol was 21, 22, 18 and 15 min. in 4 test subjects respectively.
The corresponding elimination half-lives of methanol were 213, 110, 133 and
142 min. in these same individuals.
The experimental design outlined in this paper can be used to obtain useful
data on elimination kinetics of methanol in human volunteers without undue
ethical limitations.
Circumstantial evidence is presented to link methanol or its toxic metabolic
products, formaldehyde and formic acid, with the pathogenesis of hangover.
PMID: 3588516
Jones has suggested that it is the metabolism of methanol to formaldehyde
and formic acid that causes symptoms of hangover, with quicker methanol
metabolisers suffering more.(7)  The justification for this suggestion is
threefold:
the types of drink associated with more severe hangovers contain higher
levels of methanol;
the time course of methanol metabolism corresponds to the onset of symptoms;
and a small dose of ethanol, which blocks the formation of formaldehyde and
formic acid, provides an effective treatment for hangovers ("the hair of the
dog").
Many pathophysiological disturbances occur during hangover, including
dehydration;  metabolic acidosis;  hypoglycaemia;  disturbed prostaglandin
synthesis;  abnormal secretion of vasopressin,  cortisol,  aldosterone,
renin,  and testosterone;  increased cardiac output;  tachycardia;  and
vasodilatation.
