Microwave Ovens' Effect on Food Nutrition and Cancer

Information  Microwave Ovens' Effect on Food Nutrition and Cancer

Over 90% of American homes have microwave ovens used for meal preparation. Because microwave ovens are so convenient and energy efficient, as compared to conventional ovens, very few homes or restaurants are without them. In general, people believe that whatever a microwave oven does to foods cooked in it doesn't have any negative effect on either the food or them. Of course, if microwave ovens were really harmful, our government would never allow them on the market, would they?

Many comprehensive studies have shown that microwave ovens are EXTREMELY DANGEROUS to our health. In America, neither universities or the federal government have conducted ANY TESTS AT ALL concerning the effects on our bodies from eating microwaved foods. Isn't that a bit odd? The corrupt Washington government allows the cell phone industry, Big Pharma, and the big money behind microwave ovens to cause the unessesary suffering and deaths of millions of Americans. In Russia, microwave ovens were banned in 1976 because of the negative health consequences associated with them, and after many studies were conducted on their use. Why can't the U.S. government be as concerned with their people? Here are some facts concerning microwaving food:

1. Microwaved foods lose 60 ~ 90% of the vital-energy field and microwaving accelerates the structural disintegration of foods.

2. Microwaving creates cancer-causing agents within milk and cereals.

3. Microwaving alters elemental food-substances, causing digestive disorders.

4. Microwaving alters food chemistry which can lead to malfunctions in the lymphatic system and degeneration of the body's ability to protect itself against cancerous growths.

5. Microwaved foods lead to a higher percentage of cancerous cells in the bloodstream.

6. Microwaving altered the breakdown of elemental substances when raw, cooked, or frozen vegetables were exposed for even a very short time and free radicals were formed.

7. Microwaved foods caused stomach and intestinal cancerous growths, a general degeneration of peripheral cellular tissues, and a gradual breakdown of the digestive and excretive systems in a statistically high percentage of people.

8. Microwaved foods lowered the body's ability of the body to utilize B-complex vitamins, Vitamin C, Vitamin E, essential minerals and lipotropics.

9. The microwave field next to a microwave oven caused a slew of health problems as well.
Food scientist Dr Hans Ulrich Hertel fought for 10 years to have his findings concerning the dangers of microwave ovens acknowledged. His statement that inspired the microwave manufacturers to use the Swiss courts to silence him was: 'Food cooked or defrosted in a microwave oven causes changes in the blood indicative of a developing pathological process as is also found in a carcinoma.' Put simply, microwaved food causes cancer.

In 1989 Hertel teamed up with professor Bernard Blanc of the Swiss Federal Institute of Technology. They proposed to the University of Lausanne a research programme to look into the effects of microwaved food on humans. Their application for funding was turned down on the grounds that there was no need for research in this area. Undeterred, the two scientists decided to fund a smaller research programme themselves. They selected eight individuals and fed them on a range of raw, conventionally cooked and microwaved foods. Blood samples were taken from each volunteer before and after eating. Serious irregularities were found both in the structure of the food microwaved and in the blood of those eating the microwaved samples.

The microwave industry reacted to the research by taking Hertel to court. He was convicted under Swiss unfair competition laws. And such was the pressure put on Blanc. He told Hertel that he feared for the safety of his family, and he publicly dissociated himself from the research. As soon as Doctors Hertel and Blanc published their results, the authorities reacted. A powerful trade organization, the Swiss Association of Dealers for Electro-apparatuses for Households and Industry, known as FEA, struck swiftly in 1992. They forced the President of the Court of Seftigen, Canton of Bern, to issue a 'gag order' against Drs. Hertel and Blanc. In March 1993, Dr. Hertel was convicted for 'interfering with commerce' and prohibited from further publishing his results. However, Dr. Hertel stood his ground and fought this decision over the years.

Finally this decision was reversed in a judgment delivered in Strasbourg, Austria, on August 25, 1998. The European Court of Human Rights held that there had been a violation of Hertel's rights in the 1993 decision. The European Court of Human Rights also ruled that the "gag order" issued by the Swiss court in 1992 against Dr. Hertel, prohibiting him from declaring that microwave ovens are dangerous to human health, was contrary to the right to freedom of expression. In addition, Switzerland was ordered to pay Dr. Hertel compensation.

RE: Microwave Ovens' Effect on Food Nutrition and Cancer
Found a great resource in with a fine collection of studies on the effects EMF, Microwaves, RF, Electrical Fields and Wireless Pollution in relation to human and ecological health. Be sure to cross reference the resources, check the sample sizes, the data collection process and other conditional factors that may effect the findings, as we always should, and maybe apply some biochemistry knowledge when you can to vet the studies properly.

Quote:Food quality

It is now taken for granted that the food we eat can affect our health. We are urged to eat our "5 portions a day" fresh fruit and vegetables to stay healthy and to protect us from illnesses, including cancer.

Good quality fruit, vegetables and whole grains contain all of the vitamins and minerals essential for health. In the last 150 years, the quality of the fresh food we buy has deteriorated, presumably due to farming practices (with the use of pesticides and herbicides), and to poorer quality soil. The Pesticides Residues Committee's report for the last 3 months of 2006 found about 2.5% of products tested were over "legal limits" for pesticides. To quote the Countryside Agency's Chief Executive speech in 2004, "Over the last sixty years there has been a decline in trace elements in fruit and vegetables; calcium content is down by 46%; copper by 75%; carrots have lost 75% of their magnesium and broccoli has lost 75% of its calcium**".

In order to retain as much goodness in the food we eat as possible, we need to consider not only where we buy it, but also how we cook it.

Cooking with microwaves

Microwaves from the magnetron within the oven bombard the food, causing the molecules to rotate at the same frequency millions of times a second. All this agitation creates molecular friction, which heats up the food. Of all natural substances, the oxygen of water molecules reacts most sensitively. This is how microwave cooking heat is generated -- friction from this violence in water molecules. Structures of molecules are torn apart, molecules are forcefully deformed, and thus become impaired in quality. This is contrary to conventional heating of food where heat transfers convectionally from without to within. Cooking by microwaves begins within the cells and molecules where water is present and where the energy is transformed into frictional heat.

In addition to the violent frictional heat effects, called thermic effects, there are also athermic effects which have hardly ever been taken into account. These athermic effects are not presently measurable, but they can also deform the structures of molecules and have qualitative consequences. For example the weakening of cell membranes by microwaves is used in the field of gene altering technology. Because of the force involved, the cells are actually broken, thereby neutralizing the electrical potentials between the outer and inner side of the cell membranes. Impaired cells become easy prey for viruses, fungi and other microorganisms. The natural repair mechanisms are suppressed and cells are forced to adapt to a state of energy emergency -- they switch from aerobic to anaerobic respiration. Instead of water and carbon dioxide, the cell poisons hydrogen peroxide and carbon monoxide are produced.

The same violent deformations that occur in our bodies, when we are directly exposed to microwaves, also occur in the molecules of foods cooked in a microwave oven. This radiation results in the destruction and deformation of food molecules. Microwaving also creates new compounds, called radiolytic compounds, which are unknown fusions not found in nature. Radiolytic compounds are created as a direct result of radiation.

The History and the Research

After some 20 years of research into their use, Soviet Russia banned the use of microwave ovens for heating food in 1976 as they decided that the dangers outweighed the benefit of speed.

The following is a summary of the Russian investigations that resulted in the banning of microwave ovens referred to above, published by the Atlantis Rising Educational Center in Portland, Oregon. Carcinogens were formed in virtually all foods tested. No test food was subjected to more microwaving than necessary to accomplish the purpose, i.e., cooking, thawing, or heating to insure sanitary ingestion.

Microwaving prepared meats sufficiently to insure sanitary ingestion caused formation of d-Nitrosodienthanolamines, a well-known carcinogen. Microwaving milk and cereal grains converted some of their amino acids into carcinogens. Thawing frozen fruits converted their glucoside and galactoside containing fractions into carcinogenic substances. Extremely short exposure of raw, cooked or frozen vegetables converted their plant alkaloids into carcinogens. Carcinogenic free radicals were formed in microwaved plants, especially root vegetables.

They were allowed again from 1987 when, under Perestroika, Gorbachev allowed many western business pressures to change problematic Russian regulations that did not fit in with "Western Free-Trade" practice.

Some Russian researchers, in their studies of the changes in food quality when it is cooked in a microwave oven, have reported a marked acceleration of structural degradation leading to a decreased food value of 60 to 90% in all foods tested. They found significant decreases in the bio-availability of B complex vitamins, vitamin C, vitamin E, essential minerals and lipotropics (substances that prevent abnormal accumulation of fat). This was confirmed in a Japanese study when they found that approximately 30-40% of vitamin B12 was lost in foods cooked by microwaves (Watanabe 1998). B12 deficiency is one of several factors that can cause dementia.

Dr C Garcia-Viguera (2003, 2007 (lead author Lopez-Berenguer)) found that broccoli lost 97% of its antioxidants (vitamin C) when microwaved. There were also reductions in phenolic compounds and glucosinolates. Mineral levels remained stable. In general, the authors concluded, "the longest microwave cooking time and the higher volume of cooking water should be avoided to minimise losses of nutrients." She suggested that this may apply to other vegetables, but they were not tested. It was felt that the results could show broad implications for public health.

Scientists at China Agricultural University's College of Food Science & Nutritional Engineering in Beijing looked at different forms of cooking and their production of acrylamide, a cancer-causing chemical. They found that microwaving produced more acrylamide than boiling or frying (at 180°C), and that 750 Watt ovens produced more acrylamide than 500 Watt ovens (Yuan 2007). However, Palazoglu (2008) at the University of Mersin's Department of Food Engineering (Turkey) pre-cooked (using a microwave oven) French fries to reduce the cooking time needed, as the volume of acrylamide produced is related to length of frying time. The reduction in acrylamide was 36% @ 150°C; 41% @ 170°C; and 60% @ 190°C.

There seems to be a growing body of evidence that suggests that human breastmilk or baby formula is changed if heated in a microwave. The vitamin content is depleted and certain amino acids are converted into related substances that are biologically inactive. Some of the altered amino acids are poisons to both the nervous system and the kidneys (Lee 1989). Paediatrician John Kerner and colleagues at Stanford University found that milk lost lysozome activity, antibodies, and fostered the growth of more potentially pathogenic bacteria (Quan 1992). In the early 1990s a hospital in Minneapolis, Minnesota, distributed pamphlets warning people against using microwave ovens to heat infant formulas because they altered the food. "Although microwaves heat food quickly, they are not recommended for heating a baby's bottle. The bottle may seem cool to the touch, but the liquid inside may become extremely hot and could burn the baby's mouth and throat. Also, the buildup of steam in a closed container, such as a baby bottle, could cause it to explode. Heating the bottle in a microwave can cause slight changes in the milk. In infant formulas, there may be a loss of some vitamins. In expressed breast milk, some protective properties may be destroyed. Warming a bottle by holding it under tap water, or by setting it in a bowl of warm water, then testing it on your wrist before feeding may take a few minutes longer, but it is much safer."

Microwave cooking has been shown to heat food unevenly, which means that some of the food is not heated sufficiently to kill all the bacteria or parasites that might be present. This uneven heating also creates hotspots in foods that release synthetic oestrogens found in certain plastics (Gittleman). Frozen hamburgers, fish and warmed-up dishes all may have cool areas in them that could promote the growth of pathogens. Live unkilled microbes may remain to grow in an unrefrigerated dish (Fox).

Microwave ovens from various suppliers were used to cook naturally contaminated whole chickens according to the manufacturers' instructions. Many yielded visible Listeria bacteria after microwave cooking (Food Additive Contamination).

Microwave exposure caused a higher degree of protein unfolding than usual thermal stress at the same temperature (George 2008).

The anthroposophist A Bohmert, reported the following effect that microwave heating had on water, a common component of all food products; water samples were heated, some in a microwave oven and others conventionally, and then left to cool before use. These water samples were used to bring grain to germination. The grain in contact with microwaved water was the only one that did not germinate.

Chemical leakage of packaging

Park (2006) found that not all microorganisms were destroyed by microwave radiation and could have implications for the design of containers to be used for cooking in the home microwave oven. There seem to be some problems with the packaging that is being used quite widely at the moment.

Heat susceptors are visible thin, gray strips or disks of metallized plastic that absorb microwave energy and turn the surface of the package into a very hot little frying pan (reaching temperatures of 300-500 degrees F), that can make microwaved foods brown and crisp or crunchy.

The grease-repelling papers used for some microwavable packaged foods, in particular microwavable popcorn, may be responsible for the levels of PFOA, a suspected carcinogen, in the blood of most Americans.

The January/February, 1990, Nutrition Action Newsletter reported on the leakage of numerous toxic chemicals from the "heat-susceptor" packaging of common microwavable foods, including pizzas, chips and popcorn. At the high temperatures achieved in this process, the chemicals in the plastic migrate from the susceptors into your food. The chemicals include polyethylene terpthalate (PET), a petroleum derived product), and other known or suspected carcinogens, such as benzene, toluene and xylene. Haldimann (2007) also found increased concentration of antimony (which in small doses can cause headaches, dizziness and depression), as a result of cooking with polyethylene terephthalate (PET) oven-proof trays (used to package ready-to-eat meals).

It is not recommended that food containing fat in a plastic container should be heated in a microwave oven. The combination of fat, high heat and plastics releases dioxins (a known carcinogen) and other toxins into the food.

Susan Brewster, Associate Professor of Food Chemistry at the University of Illinois, worries about the possibility that certain plasticizers could act as endocrine disruptors, which means they can potentially mimic or compete with human hormones. If they do, then that could affect such things as fertility or someone's risk of getting cancer.

Changes in the people eating microwaved foods

There has been little research on changes in the consumers of food cooked using microwaves. A piece of work carried out by Hertel and Blanc has been quoted extensively and needs following up. Although they found many and serious changes, including decreased haemoglobin levels and increased cholesterol and leukocyte levels, their research was based on just 18 people, all who ate a macrobiotic diet only, including Hertel himself. It may be that their findings are equally valid for the general public, but without further evidence, we cannot make that assumption. Tom Valentine, an independent US journalist, published the results of this study in Search for Health in the Spring of 1992.

Microwave and powerfrequency radiation from a microwave oven

The oven cables and motor give off high (over one microtesla) powerfrequency electromagnetic fields, extending for about a metre.

Microwave radiation leaks from the seal around the door and through the glass of microwave ovens. The water molecules in the body of someone standing close by will be agitated to some degree by the microwave radiation. Eyes are particularly vulnerable, as they contain large amounts of fluid and a lower blood supply to take away any heat. This is important to bear in mind with regard to children whose height and curiosity could lead to them watching the changes induced in microwave cooking from too close a distance.

Current regulations require that a microwave oven leak no more than 1 milliwatt per square centimetre (mW/cm2) when it leaves the factory, and 5 mW/cm2 after a period of use. We do not know if these levels are really safe and believe microwave ovens should be used with caution. Since microwave emissions can change with normal use, ovens should be checked regularly, preferably at least annually, to pick up any microwave leakage from the seals.

Even when the microwave oven is working correctly, the microwave levels within the kitchen are likely to be significantly higher than those from any nearby cellular phone base-stations. Remember also that microwaves will travel through walls if the microwave oven is against an inside wall.

** The reduction of trace elements in food may be due to the accelerated growth cycles and the fact that more food is grown on less land than ever before and the soil is not allowed to naturally fallow. The practices of increased use of fertilizers, food irradiation, delaying ripening with radon, shelf stagnation, monoculture, factory farming, GMOs and picking before sun ripening probably also play a role in decreased mineral concentrations.

Building on some of the same research is this 2004 research article by June Russell (original article not available since the domain was re-parked). It contains many common sense practical solutions but the best thing to do is to avoid microwave use altogether.

RE: Microwave Ovens' Effect on Food Nutrition and Cancer
Thanks for posting these articles and downloads FT. I especially like the experiment that everyone with a microwave can carry out, ie. water one plant with microwaved water and water another plant with water that hasn't been microwaved. (Let the water cool before you do your watering of course.) Observe the effects over time. Voila!
An error does not become truth by reason of multiplied propagation, nor does truth become error because nobody sees it.
