If you still believe sweeteners like Equal and NutraSweet are safe, you’ll want to pay very close attention to this special report.
You’re probably aware of the dangers of consuming too much sugar and that sugar is not healthy for you. You might have been led to believe that artificial sweeteners like aspartame are safer, and less likely to cause you to gain weight.
Well, neither of those beliefs are true.
Slick marketing of products containing aspartame by giants in the food industry -- especially marketing that sends the message it’s healthy to consume these products -- might be giving you a false sense of security.
You might even be convinced you’re doing the right thing for your health and the health of your family by using products artificially sweetened with aspartame.
You couldn’t be more mistaken.
It’s not pleasant to learn that corporations, government-sponsored regulatory agencies and politicians are more interested in lining their pockets than protecting your health and the health of your loved ones. But unfortunately, these are serious issues that you must consider for you and your family’s safety.
Manufacturers, marketers and others with financial interests have successfully convinced millions of consumers the chemicals used in artificially sweetened products are safe. Don’t believe them! The arguments used to convince you these ingredients are healthy and “natural” will be addressed later in this report.
For now, just keep in mind that the reason you feel products containing aspartame are safe is a direct result of deliberate deception on the part of big business and government.
If you’re consuming a food or beverage created in a lab instead of in nature, you can be assured your body doesn’t recognize it. This opens the door to short-term and long-lasting health problems for you and your family.
If you already avoid aspartame, the information you’re about to read will confirm the wise choice you’ve made, and cement your resolve to stay away from any product that contains this potential toxin.
An Accident Waiting to Happen: The Birth of Aspartame
Like an omen, aspartame was discovered in 1965 entirely by mistake. That’s right ... by mistake.
G.D. Searle chemist James M. Schlatter was at work in his laboratory developing a drug to treat peptic ulcer disease. The story goes that Schlatter accidentally spilled one of the chemicals he was using onto his finger. He licked his finger clean, and in doing so discovered the sweet taste of the aspartame he had spilled.
This inauspicious beginning heralded the birth of what has become one of the most potentially dangerous and controversial food additives in human history.
How Aspartame Got to Market in Spite of Itself
As you’re about to learn, the tale of how aspartame got to market is a disturbing one. It reads like a crime mystery, one you would assume is based on the author’s over-active imagination. Except it’s all true.
The approval process for aspartame was said to have been riddled with scandal, bribes and other shady dealings within the pharmaceutical industry, large American corporations, and the FDA.
Initially, the FDA strongly denied the approval of aspartame products. Reasons given were sound and included:
* Flawed data
* Brain tumor findings in animal studies
* Lack of studies on humans to determine longer-term effects
How aspartame got to market despite initial FDA concerns and evidence of its neurotoxicity is a study in good timing, heavy financial investment, and the impact of political clout.
Timing is Everything
Aspartame studies were on the rise just after cyclamate was pulled from the U.S. market and saccharin was under serious scrutiny. The disappearance of cyclamate left a void it appeared saccharin might not be poised to fill.
At the time of the cyclamate ban, the “diet” market was a $1 billion dollar per year business in the U.S. Manufacturers of diet products were in a mad scramble to find a substitute product that would insure they left not a dollar of that billion on the table.
Pouring Good Money Into Bad Studies
G.D. Searle spent tens of millions of dollars to conduct the necessary approval tests on aspartame.
Not surprisingly, studies funded by Searle and other groups with a financial interest in aspartame found no adverse health effects. However, independent studies delivered evidence aspartame consumption did indeed create health problems in test subjects.
Flexing Political Muscle
In addition to its enormous financial investment in favorable study results, Searle developed what can be fairly described as a diabolical political strategy to insure the FDA would end up with a positive view of aspartame.
Deceptive Safety Studies
G.D. Searle provided the FDA with over 100 aspartame studies in early 1973. Later that same year, the FDA asked for additional studies. Searle complied and in June 1974, the FDA granted preliminary approval for the restricted use of aspartame.
The study findings submitted by Searle were immediately challenged by Dr. John Olney, a neuroscientist who was instrumental in getting monosodium glutamate removed from baby foods, and Jim Turner, an attorney and consumer advocate.
In August 1974, Olney and Turner filed the first formal objections to the approval of aspartame. Their petition prompted the FDA to initiate investigations into Searle’s lab practices.
The investigations ultimately led to concerns within the FDA about the validity of the studies submitted by Searle. Investigators uncovered substandard testing procedures and manipulated test data. In fact, what investigators found at Searle was an unprecedented incidence of bad testing procedures and inaccurate results. Final approval of aspartame was delayed.
Based on the results of these findings, in January 1977, for the first time in history, the FDA requested a criminal investigation into a food manufacturer for willfully misrepresenting results in their safety tests of a product. The FDA asked the U.S. Attorney’s office to examine Searle’s handling of aspartame testing.
In August 1977, the FDA published a report by Jerome Bressler which pointed to specific issues with Searle’s aspartame safety studies.
The Bressler Report revealed stunning examples of very bad research. A few examples included:
* Deceased lab animals were not immediately autopsied, some not for an entire year after death. Decomposition rendered any data from them inaccurate.
* Tumors found in lab animals were reportedly cut out and thrown away.
* Animals from whom tumors were removed were labeled “normal,” and obvious tumors were deemed to be “normal swelling.”
In 1979, the FDA established a Public Board of Inquiry (PBOI) to rule on safety issues with aspartame, with the result that NutraSweet would not receive final approval pending further investigation into its link to brain tumors in animals.
Political and Regulatory Dirty Tricks
During the 1977 criminal investigation initiated by the FDA, the law firm representing G.D. Searle arranged to hire away the U.S. Attorney leading the investigation. Samuel Skinner went to work for Searle in July.
Skinner’s resignation from the U.S. Attorney’s office stalled the investigation into Searle’s aspartame studies until the statute of limitations expired. The investigation was subsequently abandoned.
In March 1977, Donald Rumsfeld was hired as the CEO of Searle -- yes, the same Rumsfeld that was the Secretary of Defense in the Bush administration. He brought with him additional political clout by appointing several of his D.C. associates to top management positions.
In January 1981, Rumsfeld proclaimed he would get aspartame approved within one year. Worthy of note is the fact Rumsfeld was part of newly elected President Ronald Reagan’s transition team -- a team which had carefully selected Dr. Arthur Hull Hayes Jr. as the new FDA Commissioner.
Two months later, in March, Dr. Hayes appointed an internal panel to review the 1979 decision by the Public Board of Inquiry that ruled thumbs down on final approval of NutraSweet.
Three of the five members of Dr. Hayes’ panel advised against approval of aspartame, citing on the record that Searle’s safety study tests were flawed. Hayes then appointed a sixth member to the panel who tied the vote three-three. Dr. Hayes then cast the deciding vote in favor of approval.
Hayes, an official with no background on the subject of food additives, claimed aspartame was safe for proposed use, and had undergone more testing and scientific scrutiny than most additives on the market. Shortly after approving this drug he resigned from the FDA panel and was hired by the manufacturer of aspartame for a position in which he was paid several hundred thousand dollars per year.
So, despite all the game playing and countless unresolved safety issues, aspartame was approved for use in soft drinks in the fall of 1983.
Less than a year later, the FDA had recorded 600 consumer complaints of headaches, dizziness and other health-related reactions from aspartame consumption.
The unprecedented number of complaints caused the FDA to call in the CDC (Centers for Disease Control). The CDC concluded adverse reactions to aspartame were occurring in “unusually sensitive” individuals, but there was not enough evidence to prove existence of wide-spread health problems attributable to its consumption.
What is Aspartame, Exactly?
Aspartame goes by the brand names NutraSweet and Equal. It is one of the first generation of artificial sweeteners and is 180 times as sweet as sugar.
At the end of 2008, aspartame was found in over 6,000 products including:
carbonated soft drinks
puddings and fillings
powdered soft drinks
sugar-free cough drops
Products containing aspartame are sold in over 100 countries and are consumed by over 250 million people worldwide.
The scientific name for aspartame is 1-aspartyl 1 phenylalanine methyl ester. It has three components:
1. phenylalanine which makes up 50 percent of the chemical by weight
2. aspartic acid -- 40 percent
3. methanol (wood alcohol) -- 10 percent
How Aspartame Acts Inside Your Body
The two primary components of aspartame, phenylalanine and aspartic acid, are amino acids that are combined in an ester bond. You normally consume these two amino acids in the foods you eat. These amino acids are harmless when consumed as part of natural unprocessed foods. However when they are chemically manipulated and consumed out of the normal ratios to other amino acids, they can cause problems.
Your body initially breaks down the ester link between the two amino acids to turn them into free amino acids. The neurotoxic effects of these chemicals in their “free form” can result in immediate health consequences such as headaches, mental confusion, dizziness and seizures.
Your body does require small amounts of these amino acids to function properly. However, the high concentration of these chemicals in the form of aspartame floods your central nervous system and can cause excessive firing of brain neurons. Cell death is also possible.
This is a condition called excitotoxicity.
Your body doesn’t recognize phenylalanine and aspartic acid in their free form, but your system will try to manage them through metabolization. Whenever your body tries to process an unrecognizable substance, the stage is set for health problems.
The chemicals in aspartame will be absorbed by your intestinal cells, where they will be broken down into other amino acids and byproducts. A large percentage of the absorbed chemicals will be used immediately in your small intestine.
A Formaldehyde Cocktail
Ultimately, aspartame will be fully absorbed into your body. Ten percent of what is absorbed is the breakdown product methanol (wood alcohol). The EPA defines safe consumption of this toxin as 7.8 milligrams a day, which is the amount found in about half a can of diet soda.
It’s not the amino acids themselves or the methanol that are toxic to your system, it’s the breakdown products they turn into along the way -- either during transport, on the store shelf, or during the metabolization process.
Stored at warm temperatures or for a prolonged period of time, phenylalanine turns into diketopiperazine, a known carcinogen.
Methanol can spontaneously break down to formaldehyde, also a toxin, which can accumulate in your cells and result in severe health consequences.
Methanol is found naturally in some of the foods you eat; however, it is never bound to amino acids in nature, as it is as an ingredient in aspartame. In nature, for example, methanol is bound to pectin. Pectin is a fiber which allows the methanol to pass through your body without being metabolized and converted to formaldehyde.
Since methanol in aspartame has no natural binder, nearly all of it turns into formaldehyde in your body. Formaldehyde (which is used in, among other things, paint remover and embalming fluid) is a poison several thousand times more potent than ethyl alcohol.
The EPA has determined formaldehyde causes cancer in humans. Specifically, it is known to increase your risk of breast or prostate cancer.
Incidents of both types of cancer have been on the rise at a pace closely associated with the expanding use of aspartame throughout the world.
The EPA has also concluded there is no known “safe” level of formaldehyde in your body -- risk depends on the amount and duration of your exposure.
The end waste product of formaldehyde is formate. An accumulation of formate in your body can cause metabolic acidosis, which is excessive acidity in your blood. Metabolic acidosis can cause methanol poisoning and can result in blindness, fatal kidney damage, multiple organ system failure, and death.
The Major Element of Aspartame -- Phenylalanine
Your body converts the amino acid phenylalanine to neurotransmitters that regulate your brain chemistry. These important neurotransmitters are:
However, if your system is flooded with phenylalanine as a result of an aspartame overdose, the resulting increased levels of neurotransmitters can cause problems in the physiology of your brain -- problems which have been linked to a variety of psychiatric disorders. You can also be prone to anxiety attacks, depression, headaches, seizures and tremors.
If you consume too much aspartame in a short period of time, you might also experience immediate reactions including nervousness, sweating, feelings of fear, and heart palpitations.
In pregnancy, the concentrating effects of the placenta can magnify phenylalanine levels in a baby’s blood by as much as four to six-fold, and can reach levels so high that cell death results. It’s not much of a stretch to be concerned consumption of high doses of this chemical during pregnancy could result in birth defects.
The genetic disease Phenylketonuria (PKU) is a condition in which your body is unable to use phenylalanine at all. If a toxic buildup occurs, it can result in mental retardation. People with PKU must avoid all sources of phenylalanine, including aspartame.
Aspartic Acid and Cell Death
The second largest component of aspartame is aspartic acid.
Aspartic acid functions as a major excitatory neurotransmitter in your brain. People who suffer from depression or have brain atrophy have been found to have low levels of aspartic acid in their bodies.
As you might expect, the chemical is found in abnormally high levels in people who suffer from seizures and strokes. In very high doses, aspartic acid can cause brain damage.
The term excitotoxicity was coined by Dr. Russell Blaylock, a neurosurgeon. It describes the ability of certain amino acids like monosodium glutamate (MSG) and aspartic acid to literally excite cells to death.
The scientific community has shown widespread acceptance of Dr. Olney’s concept of excitotoxins and its link to neurodegenerative diseases like Parkinson’s and Alzheimer’s.
Unfortunately, the FDA refuses to acknowledge the connection between free form amino acids and excitotoxicity. Consequently, no demands have been made of food manufacturers to eliminate chemicals like MSG and aspartic acid from the food supply.
Excitotoxins can also encourage the production of free radicals. Free radicals can damage tissues and organs throughout your body and may accelerate diseases like arthritis, atherosclerosis, cancer, and coronary artery disease.,
Your blood brain barrier (BBB) is a system of capillary structures that prevent toxins from entering your brain.
If you have diabetes, hypertension or are a smoker, your BBB may be compromised and you might experience a heightened reaction to aspartame.
Unborn children and infants up to one year of age have incomplete and not well-insulated BBB’s. Excitotoxins enter their nervous systems easily and quickly.
Babies under a year are four times more sensitive to excitotoxins than adults.
During the first year of life, irreversible brain damage can result from chemicals in breast milk that have crossed the unborn child’s blood brain barrier. And yet -- few if any pregnant and breastfeeding women are warned of the dangers of consuming artificial sweeteners.
Are Your Health Problems Related to Aspartame Consumption?
You might not realize you’re having a reaction to aspartame. In fact, most people don’t make the connection, and a tremendous amount of time and money is spent by aspartame “reactors” (people sensitive to the chemical), trying to find out why they are sick.
To determine if you’re a reactor, take the following steps:
1. Eliminate all artificial sweeteners from your diet for one to two weeks.
(Note: If you typically consume aspartame in caffeinated drinks, you’ll want to gradually reduce your intake in order to avoid caffeine withdrawal symptoms.)
2. After one to two weeks of being artificial sweetener-free, reintroduce aspartame or other artificial sweetener in a significant quantity (at least three servings daily) and avoid other artificial sweeteners during this period.
3. Do this for one to three days and notice how you feel, especially as compared to when you were consuming no artificial sweeteners.
4. If you don’t notice a difference in how you feel after re-introducing aspartame, it’s a safe bet you’re able to tolerate aspartame acutely, meaning your body doesn’t have an immediate, adverse response. However, this doesn’t mean your health won’t be damaged in the long run by this chemical and its breakdown products.
Keep in mind aspartame is completely metabolized by the human body, and its byproducts can create a serious risk to your health. Neurological damage can occur from long-term aspartame use.
Adverse Reactions to Aspartame
There have been more reports to the FDA for aspartame reactions than for all other food additives combined. And, there are over 900 published studies on the health hazards of aspartame. You can find a list in the National Library Medicine Index.
There are also some 10,000 documented reports of adverse reactions to aspartame, including death. Since it is estimated only about one percent of people who experience a reaction report it, it is safe to assume at least a million people have had a reaction to this chemical.
Migraines are by far the most frequently reported reaction. Other commonly reported symptoms of an aspartame reaction include:
change in mood
change in vision
convulsions and seizures
change in heart rate
nausea and vomiting
fatigue and weakness
Debilitating, Life-Threatening Conditions Linked to Aspartame
Aspartame has been implicated in a number of diseases, and there is special concern among doctors and scientists regarding the role aspartame plays in migraine headaches, epilepsy and neuropsychiatric disorders.
Aspartame has been identified as a definitive causative factor in the following serious health concerns:
Aspartame has been shown to trigger migraines, and to cause more frequent, severe headaches in regular sufferers. This is especially true with long-term exposure to the chemical.
In the mid 1990’s, a hotline was established specifically for pilots to report acute adverse reactions to aspartame. The hotline received several hundred calls from pilots complaining about reactions to the chemical, including many who suffered grand mal seizures while in the cockpit.
In 1992, the United States Air Force issued a warning to pilots to avoid products containing aspartame because it has been linked to seizures and vertigo, dizziness, sudden memory loss and gradual loss of vision.
Seizures are a primary side effect of aspartame consumption. As if that weren’t disturbing enough, they occur in people who’ve never had a seizure before, and disappear just as quickly when aspartame consumption is stopped.
MIT conducted a survey of 80 seizure sufferers. Survey results showed the role aspartame played in those seizures met FDA criteria for an imminent hazard to the public’s health. This measure is what the FDA normally relies upon to pull unsafe products from the market. Products other than aspartame,apparently.
A study begun at Northeastern Ohio University to determine whether aspartame was linked to depression had to be halted. Can you guess why?
Nearly a third of the test subjects in the depressive group dropped out due to the severity of their reactions to aspartame consumption. Two others left the study due to serious eye problems -- one developed a detached retina that ultimately led to blindness, and the other experienced a bleeding conjunctiva of the eye.
The individual ingredients in aspartame as well as their breakdown products can do serious harm to your retina and optic nerves. Aspartame has been linked to blurred vision, eye pain, visual hallucinations and blindness.
Formaldehyde is known to cause retinal damage, and methanol poisoning can lead to changes in your vision and ultimately, blindness.
According to Dr. H.J. Roberts, an expert on aspartame who has treated hundreds of patients with sensitivity to the chemical, the visual problems seen in frequent aspartame users are identical to those found in people who developed methanol poisoning from wood alcohol during the era of prohibition.
The subject of aspartame and cancer continues to be controversial. However, there is sufficient evidence of a link to warn off anyone who is concerned about maintaining good health.
On the heels of its approval for use in diet soda in 1983, over a million pounds of aspartame was consumed. Less than a year later, in January 1984, the incidence of brain cancer took off at a rate far higher than any other type of cancer.
According to the National Cancer Institute, there was a 10 percent increase in malignant brain cancer in 1985 -- just two years after aspartame flooded the market in diet beverages.
Young women who drink large quantities of aspartame-laced diet drinks are especially susceptible to developing three specific types of brain cancer:
Equally alarming is evidence women of childbearing age who consumed aspartame during pregnancy were delivering babies with an increased risk of brain and spinal cord cancer.,
Aspartame and Weight Gain
Would it surprise you to learn aspartame may cause you to gain weight? It’s true -- products marketed as “reduced calorie,” “sugar-free,” and “diet” can actually sabotage your weight control efforts.
The two main ingredients of aspartame, phenylalanine and aspartic acid, stimulate the release of insulin and leptin -- hormones which instruct your body to store fat.
In addition, a large intake of phenylalanine can drive down your serotonin levels. Serotonin is the neurotransmitter that tells you when you’re full. A low level of serotonin can bring on food cravings which can lead to weight gain.
What Will You Do, Now That You Know?
I hope this report has convinced you one of the worst things you can put into your body, or feed to your family, is the artificial sweetener aspartame.
You can read more about aspartame and other artificial sweeteners in my comprehensive book, Sweet Deception, as well as in the outstanding book by H.J. Roberts, Aspartame Disease -- An Ignored Epidemic. I also recommend you watch the excellent documentary Sweet Misery.
Neotame: The “New and Improved” Aspartame
You’ll also want to be on the lookout for this modified version of aspartame, as it likely carries similar health risks to the original.
Neotame is chemically related to aspartame, but has greater heat stability and is 72 times sweeter.
Breaking the Cycle
If you consume a lot of “diet” products, you probably have cravings for sweet foods and beverages.
Because if your body isn’t receiving the fuel it needs in the right combinations, you’ll develop sweet cravings.
To optimize your diet, you’ll want to determine your nutritional type, and begin to eat the kinds of foods your body requires.
When you are eating right for your nutritional type, your sweet cravings will disappear.
There may also be an emotional component to your cravings. If so, you’ll need to address it, as well. I highly recommend the Emotional Freedom Technique (EFT) or a medical hypnosis program.
I can’t overstate the importance of avoiding aspartame to your short and long-term health, the quality of your life, and the lives of your loved ones. I hope you’ll take this information to heart and eliminate aspartame and other artificial sweeteners from your diet.

Low levels of vitamin D may increase the risk of dying from all causes by 150 per cent, suggests a study with over 700 elderly women.
Women with blood levels of the vitamin lower than 15.3 nanograms per millilitre were more likely to die from causes such as heart disease and cancer, than women with higher levels (above 27 ng/ml), according to findings published in Nutrition Research,
“The present findings from this population-based cohort of ageing are consistent with the association between low serum 25(OH)D and mortality that has been described in […] the general population,” wrote the researchers, led by Richard Semba from the Johns Hopkins University.
“In addition, a recent meta-analysis suggested that vitamin D supplementation was associated with decreased mortality,” they added.
The researchers noted that several biologic mechanisms could explain a causal relationship between vitamin D deficiency and mortality, with the vitamin’s active form (1,25-dihydroxyvitamin D) linked to a range of effects including control of inflammatory compounds, regulating immune health and blood pressure, or reducing arterial hardening.
“The role that vitamin D plays in different tissues may account for the associations between vitamin D deficiency and cardiovascular disease, cancer, and mortality,” they said.
When the researchers divided women into four groups (quartiles) according to their 25(OH)D levels, the proportion of women who died in during those 6 years in each quartile (from lowest to highest) was 19, 13,15, and 8.1 per cent, said the researchers.
Increasing blood levels of vitamin D were linked to increasing survival rates, with women with the lowest average 25(OH)D levels having “significantly worse survival” than women with the highest average levels of 25(OH)D.
“Controlled clinical trials are needed to determine whether vitamin D supplementation will improve health outcomes such as cardiovascular disease and mortality in older adults who have insufficient levels of vitamin D,” concluded the researchers.
Vitamin D refers to two biologically inactive precursors - D3, also known as cholecalciferol, and D2, also known as ergocalciferol. The former, produced in the skin on exposure to UVB radiation (290 to 320 nm), is said to be more bioactive.
While our bodies do manufacture vitamin D on exposure to sunshine, the levels in some northern countries are so weak during the winter months that our body makes no vitamin D at all, meaning that dietary supplements and fortified foods are seen by many as the best way to boost intakes of vitamin D.
In adults, it is said vitamin D deficiency may precipitate or exacerbate osteopenia, osteoporosis, muscle weakness, fractures, common cancers, autoimmune diseases, infectious diseases and cardiovascular diseases. There is also some evidence that the vitamin may reduce the incidence of several types of cancer and type-1 diabetes.
NEW YORK (Reuters Health) - As if you needed another reason to drink green tea: Japanese women, but not Japanese men, who regularly drink 5 or more cu
NEW YORK (Reuters Health) - As if you needed another reason to drink green tea: Japanese women, but not Japanese men, who regularly drink 5 or more cups daily appear about 20 percent less likely to develop stomach cancer, study findings hint.
Researchers have studied green tea in cancer prevention because they suspect that the drink's antioxidants may protect against the deadly disease. In particular, it may include compounds that fight bacteria that have been linked to stomach cancer.
However, previous studies were inconsistent, researchers write their report in the journal Gut. To get a better sense of green tea's potential effects, Dr. M. Inoue, at the National Cancer Center in Tokyo, examined six older studies.
Together, these studies involved more than 219,000 men and women 40 years and older, who were followed from about 7 years to more than 11 years. Overall, about four in five of the participants reported drinking green tea daily, with about a third drinking five or more cups per day.
During follow-up, about 2500 of the approximately 100,000 men, and about 1000 of the more than 118,000 women in the studies developed stomach cancer.
The researchers found no link between more tea drinking and reduced stomach cancer risk among men.
The 20 percent reduced stomach cancer risk they saw among women drinking 5 or more, versus 1 or less, cups of green tea daily remained true even after the researchers took smoking into account. They note, however, that the decreased risk only applied to cancers in certain parts of the stomach.
While the study does not prove a cause-effect relationship, the authors suggest more research to figure out whether drinking green tea actually decreases the risk of stomach cancer, or whether women with a lower risk only happen to drink more of it.

Many fruit and vegetables sold in supermarkets and greengrocers contain pesticide residues that are above the maximum legal level, an in-depth report has said.
Apples, peas, and grapes are sometimes covered in crop spray that is above the maximum allowed levels allowed under European law.
The findings come from the Pesticides Residues Committee, part of the Health and Safety Executive, after testing more than 4,000 samples of food and drink.
The levels of pesticides varied considerably, with imported fruit and vegetables tending to have higher levels, according to its 2008 annual report. One in 7 beans in a pod one in 25 fresh peas (in pods) and one in five yams all had pesticides above the allowed level. One in 70 apples and pears had illegal levels of pesticides.
The Food Standards Agency insisted the illegal levels did not necessarily mean that the food was unsafe to eat, and pointed out that the overall levels of pesticides in food had fallen over the last year. In 2007 1.8 per cent of food had illegal levels; 2008 it had fallen to 1.2 per cent.
All of the fruit and vegetables supplied to schools contained pesticides within allowed levels, though nearly all the apples (49 out of 52 tested) and every one of the bananas had some form of pesticide in them. Many of the pieces of fruit had more than one pesticide.
The Soil Association, which represents the organic industry, said the report was alarming nonetheless.
Emma Hockridge, policy co-ordinator at the Soil Association, said: "Unbelievably we learn yet again that pesticides are turning up in fruit and vegetables supplied to schoolchildren. Yet again the government tells us this is nothing to be worried about.
"Yet we know that children’s exposure and susceptibility to pesticides is likely to be higher as per body weight they ingest more food and drink than adults and their bodies' ability to process and excrete any such residues is different to that of adults.
"It is unacceptable that 94 per cent of apples, and 100 per cent of bananas tested contained pesticides school fruit and vegetable scheme."
She argued that the "cocktail" effect of different pesticides had never been tested properly. "Powerful new evidence is emerging that suggests the combined effect of pesticide ‘mixtures’ may be more significant than previously realised, especially with regard to endocrine disruptors," she said.
Pesticides, at high doses, can cause allergic reactions such as causing itchy skin and breathing difficulties.

WASHINGTON (Reuters) - A diet high in a form of sugar found in sweetened soft drinks and junk food raises blood pressure among men, according to research likely to mean more bad news for beverage companies and restaurant chains.
One of two studies released on Wednesday provided the first evidence that fructose helps raise blood pressure. It also found that the drug allopurinol, used to treat gout, can alleviate the effect by reducing uric acid levels in the body.
The second study, which measured fructose intake in mice, suggested that people who consume junk foods and sweetened soft drinks at night could gain weight faster than those who don't.
"These results suggest that excessive fructose intake may have a role in the worldwide epidemic of obesity and diabetes," said Dr. Richard Johnson of the University of Colorado-Denver, who studied the link between blood pressure and men.
The findings provide the latest evidence of ties between sugar-rich diets and health problems that have prompted some experts to call for a tax on sugary soft drinks.
Fructose accounts for about half the sugar molecules in table sugar and in high-fructose corn syrup, the sweetener used in many packaged foods.
Johnson and colleagues at the Mateo Orfila Hospital in Spain studied 74 men given 200 grams of fructose per day on top of their regular diet. That amount is well above a daily intake of 50 grams to 70 grams of fructose consumed by most American adults.
Half the men were also given allopurinol.
After two weeks, the men who received only the fructose registered increases of six millimeters in systolic blood pressure -- the top reading -- and about three millimeters in diastolic or the bottom reading, the researchers told an American Heart Association meeting in Chicago.
Most of their blood pressure readings returned to normal levels after two months.
The men who did not get allopurinol also were twice as likely to develop metabolic syndrome, measured by risk factors such as too much abdominal fat, high blood pressure and poor cholesterol readings.
By contrast, those given allopurinol and fructose had significantly lower uric acid levels, and virtually no increase in systolic blood pressure or higher risk of metabolic syndrome.
For the second study, researchers in Ohio studied mice given fructose water to drink. Some had unrestricted access, while others received it during the day or at night.

A doctor's letter written more than 400 years ago has revealed medics then were concerned about the dangers of young people smoking.
The letter, by Dr Eleazar Duncon, was unearthed by library staff at the Royal College of Physicians of Edinburgh (RCPE) as they prepared for an exhibition.
And Professor Sir Neil Douglas, the president of the RCPE, said it gave a "fascinating insight into historical concerns" about smoking and young people.
On Thursday MSPs at Holyrood will consider the general principles of Scottish Government proposals aimed at curbing the sale of cigarettes and tobacco to youngsters.
But Dr Duncon's letter, which was published by his employer in 1606, reveals medics were concerned about the issue four centuries ago.
The letter concluded that tobacco "is so hurtful and dangerous to youth that it might have the pernicious nation expressed in the name, and that it were as well known by the name of Youths-bane as by the name of tobacco.”
The RCPE president commented on the letter and said: "This letter from our library collection provides a fascinating insight into historical medical concerns about the addictive nature of smoking and young people, and shows that this issue has been of concern for over four centuries."
He went on: "The Scottish Parliament has already taken a political lead, and demonstrated its commitment to tackling0 the harm caused by tobacco, by introducing smoke-free legislation for public places.
"However, it would be easy for politicians to think that the problems associated with tobacco have been dealt with and to lose sight of the fact that the proposed Bill includes critically important measures aimed at reducing smoking in young people.
"These measures principally involve ending point of sale advertising and banning vending machines, both of which encourage and influence young people to smoke.
"We therefore urge MSPs from all parties to support this important Bill and to take this historic opportunity to reduce the harm caused by smoking in the young."
