El microondas

A study published in the November 2003 issue of The Journal of the Science of Food and Agriculture[5] found that broccoli "zapped" in the microwave with a little water lost up to 97 percent of its beneficial antioxidants. By comparison, steamed broccoli lost 11 percent or fewer of its antioxidants. There were also reductions in phenolic compounds and glucosinolates, but mineral levels remained intact.
A 1999 Scandinavian study of the cooking of asparagus spears found that microwaving caused a reduction in vitamin C[6] .
In a study of garlic, as little as 60 seconds of microwave heating was enough to inactivate its allinase, garlic's principle active ingredient against cancer[7] .
A Japanese study by Watanabe showed that just 6 minutes of microwave heating turned 30-40 percent of the B12 in milk into an inert (dead) form[8] . This study has been cited by Dr. Andrew Weil as evidence supporting his concerns about the effects of microwaving. Dr. Weil wrote:
"There may be dangers associated with microwaving food... there is a question as to whether microwaving alters protein chemistry in ways that might be harmful."
A recent Australian study[9] showed that microwaves cause a higher degree of "protein unfolding" than conventional heating.
Microwaving can destroy the essential disease-fighting agents in breast milk that offer protection for your baby. In 1992, Quan found that microwaved breast milk lost lysozyme activity, antibodies, and fostered the growth of more potentially pathogenic bacteria[10] .

Quan stated that more damage was done to the milk by microwaving than by other methods of heating, concluding: "Microwaving appears to be contraindicated at high-temperatures, and questions regarding its safety exist even at low temperatures."

Another study about breast milk/infant formula by Lee in 1989[11] found vitamin content becomes depleted by microwaving, and certain amino acids are converted into other substances that are biologically inactive. Some altered amino acids are poisons to the nervous system and kidneys. (Numerous authors mention this study, yet I was unable to find the original article/study, so I cannot personally validate.)

Although many of the above studies are not new, there is certainly ample evidence that microwaving is NOT good for your food.

How Your Microwave Actually Heats Your Food

Microwaves are a form of electromagnetic radiation—waves of electrical and magnetic energy moving together through space. EM radiation ranges from very high energy (gamma rays and x-rays) on one end of the spectrum to very low energy (radio waves) on the other end of the spectrum.

Microwaves are on the low energy end of the spectrum, second only to radio waves. They have a wavelength of about 4.8 inches—about the width of your head.

Microwaves are generated by something called a magnetron (a term derived from the words "magnet" and "electron"), which is also what enabled airborne radar use during WWII. Hence the early name for microwave ovens: radar ranges.

A magnetron is a tube in which electrons are subjected to both magnetic and electrical fields, producing an electromagnetic field with a microwave frequency of about 2,450 megaHertz (MHz), which is 2.4 gigaHertz (GHz).

Microwaves cause dielectric heating. They bounce around the inside of your oven and are absorbed by the food you put in it. Since water molecules are bipolar, having a positive end and negative end, they rotate rapidly in the alternating electric field. The water molecules in the food vibrate violently at extremely high frequencies—like millions of times per second—creating molecular friction, which heats up the food.

If the food or object place in the microwave had no water it would not be able to have this resonance heating type effect and would remain cool. Or, as investigative journalist William Thomas[12] calls it, "electrical whiplash."

Structures of the water molecules are torn apart and forcefully deformed. This is different than conventional heating of food, whereby heat is tras*ferred convectionally from the outside, inward. Microwave cooking begins within the molecules where water is present.

Contrary to popular belief, microwaved foods don't cook "from the inside out." When thicker foods are cooked, microwaves heat the outer layers, and the inner layers are cooked mostly by the conduction of heat from the hot outer layers, inward.

Since not all areas contain the same amount of water, the heating is uneven.

Additionally, microwaving creates new compounds that are not found in humans or in nature, called radiolytic compounds. We don't yet know what these compounds are doing to your ******

In addition to the violent frictional heat effects, called thermic effects, there are also athermic effects, which are poorly understood because they are not as easily measured. It is these athermic effects that are suspected to be responsible for much of the deformation and degradation of cells and molecules. [13]

As an example, microwaves are used in the field of gene altering technology to weaken cell membranes. Scientists use microwaves to actually break cells apart. Impaired cells then become easy prey for viruses, fungi and other microorganisms.8

Another word for these athermic effects is the "microwave effect," a subject of controversy that I'll get into a bit later.

Microwave Sickness

When your tissues are directly exposed to microwaves, the same violent deformations occur and can cause "microwave sickness."

People who have been exposed to high levels of microwave radiation experience a variety of symptoms, including:

Insomnia, night sweats, and various sleep disturbances
Headaches and dizziness
Swollen lymph nodes and a weakened immune system
Impaired cognition
Depression and irritability
Nausea and appetite loss
Vision and eye problems
Frequent urination and extreme thirst

There is a good amount of data emerging that people are suffering, to various degrees, these kinds of symptoms from living next to cell phone towers and other high-frequency radiation emitting antennas, which emit microwaves around the clock.

According to Professor Franz Adelkofer, a leading scientist in the area of biological effects of EMF fields:

"There is real evidence that hyperfrequency electromagnetic fields can have geno-toxic effects. And this damaged DNA is always the cause of cancer.

We've found these damaging effects on the genes at levels well below the safety limits. That's why we think it's urgent to base our safety limits on the biological effects, not the thermic ones.

They should be based on biology, not on physics."

Twenty Years of Russian Research Supports Microwave Concerns

The Nazis are credited with inventing the first microwave-cooking device to provide mobile food support to their troops during their invasion of the Soviet Union in World War II[14] . These first microwave ovens were experimental. After the war, the US War Department was assigned the task of researching the safety of microwave ovens.

But it was the Russians who really took the bull by the horns.

After the war, the Russians had retrieved some of these microwave ovens and conducted thorough research on their biological effects. Alarmed by what they learned, the Russians banned microwave ovens in 1976, later lifting the ban during Perestroika.

Twenty years of Russian research (and German studies as far back as 1942 Berlin) make a strong argument against the safety of microwave cooking.

Their findings led the Russian government to issue an international warning about possible biological and environmental damage associated with the use of microwave ovens and other similar frequency electronic devices (e.g. mobile phones).

I was not able to personally evaluate any of these older bodies of research, since those documents are now difficult to track down, so I can't attest to their methodology or conclusions. All you can do is weigh their findings appropriately, as best you can.

The Powerwatch article cited above summarizes the Russian research quite well, which I will duplicate below.

Russian investigators found that carcinogens were formed from the microwaving of nearly all foods tested.
The microwaving of milk and grains converted some of the amino acids into carcinogenic substances.
Microwaving prepared meats caused the formation of the cancer-causing agents d-Nitrosodienthanolamines.
Thawing frozen fruits by microwave converted their glucoside and galactoside 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.
Structural degradation leading to decreased food value was found to be 60 to 90 percent overall for all foods tested, with significant decreases in bioavailability of B complex vitamins, vitamins C and E, essential minerals, and lipotropics (substances that prevent abnormal accumulation of fat).

I might add that this finding is supported by the 1998 Japanese study by Watanabe7 about vitamin B12 in milk, cited above.

The Swiss Clinical Study: Hans Hertel

Some fairly compelling evidence supporting the destructive effects of microwaves comes from a highly cited study by a Swiss food scientist named Hans Hertel. Dr. Hertel was the first scientist to study the effects of microwaved foods on the blood and physiology of human beings.

His small study, coauthored by Dr. Bernard Blanc of the Swiss Federal Institute of Technology and the University Institute for Biochemistry, revealed the degenerative forces produced by microwave ovens on the foods they cooked.

Dr. Hertel concluded that microwave cooking changed the nutrients in the food, and that changes took place in the blood that could cause negative health effects.

Hertel's conclusions were that microwaving food resulted in:

Increased cholesterol levels
Decreased numbers of leukocytes (white blood cells), which can suggest poisoning
Decreased numbers of red blood cells
Production of radiolytic compounds
Decreased hemoglobin levels, which could indicate anemia

Not surprisingly, Dr. Hertel's study was met with great resistance from those with much to lose.

A gag order against Dr. Hertel was issued by a Swiss trade organization in 1992, which was later removed in 1998. But an American journalist, Tom Valentine, published the results of Hertel's study in Search for Health in the spring of 1992[15] .

The study was not without its shortcomings. It involved only eight participants, of which Hertel was one. As compelling as his findings were, his methodology did not stand up to the scientific rigors of the field.

In spite of Hertel's methodological shortcomings, his findings do raise concerns about what this form of radiation is doing to your food and should be taken as a launching point to larger, more robust studies in the future.

Hertel wrote:

"There are no atoms, molecules, or cells of any organic system able to withstand such a violent, destructive power for any period of time. This will happen even given the microwave oven's low power range of milliwatts."

And then there is the issue of biophotons.

Possible Microwave Effects on Your Biophotons

Biophotonics is the study, research, and applications of photons in their interactions within and on biological systems. Much of the work in the area of biophotons was done in Germany. Dr. Dietrich Klinghardt discusses biophotons in our 2008 interview.

Biophotons are the smallest physical units of light that are stored in and used by all biological organisms—including you. Vital sun energy finds its way into your cells via the food you eat, in the form of these biophotons.

Biophotons contain important bio-information and are very important to many vital processes in your ****** They are partly responsible for your feeling of vitality and well-being. You gain biophotons by eating foods rich in them, such as naturally grown fresh vegetables and sun-ripened fruits, which are rich in light energy.

The more light energy a food is able to store, the more nutritious it is.

If the "microwave effect" exists (as you shall see, there is a huge amount of evidence that it does), then microwaves can potentially destroy biophotons in the same way that it alters other structures, rendering your food dead and lifeless.

It seems quite plausible that microwaves could disrupt or destroy biophotons, since they are capable of breaking apart DNA bonds!

As far as I can find, there haven't been any studies of the direct effects of microwave radiation on biophotons, but it seems like an important angle of investigation for the future.

Long-Term Effects of Exposure to Non-Ionizing Radiation

One of the basic controversies about the effects of microwaves centers on whether or not microwaves exert some sort of force beyond heat, commonly called "microwave effect" or "athermic effect."

It is first necessary that you understand the difference between ionizing radiation and non-ionizing radiation.

There are two basic forms of radiation: ionizing and non-ionizing[16] :

Ionizing Radiation: Creates charged ions by displacing electrons in atoms, even without heat. Examples are radiation emitted from radioactive substances in rocks and soil, cosmic rays of the sun, and radiation from man-made technology such as x-rays machines, power stations, and nuclear reactors.
Non-ionizing Radiation: Can change the position of atoms but not alter their structure, composition, and properties. Examples are visible light, ultraviolet and infrared waves, waves from radio or television, cellular phones, microwaves, and electric blankets.

Despite not being able to break atoms apart, non-ionizing radiation (such as microwaves) CAN cause physical alterations.

For example, sunlight can damage your skin and eyes. Overexposure to radiation can affect tissues by causing molecular damage, DNA mutations, and other changes that can lead to cancer.

The serious concern is, with all of this radiation surrounding us from cell and cordless phones, radio towers, satellites, broadcast antennas, military and aviation radar, home electronic devices, computers and Internet, we are all part of an involuntary mass epidemiological experiment, on a scale never before seen in the history of the human race.

And the truth is that we don't really KNOW what long term, low-level (but persistent) radiation does to us—even the non-ionizing type.

But here are some of the things we DO KNOW:[17]

Effects at low levels can be more noticeable than at higher levels. There is something called a "window effect," meaning an effect occurring only at specific frequencies or power densities, but not occurring just above or below them. A number of studies demonstrate effects of microwave radiation on blood cells via this phenomenon.
For a complete discussion of this, you can read Microwaving Our Planet, written by Arthur Firstenberg, president of the Cellular Phone Taskforce.
Cindy Sage of Sage Associates, an environmental consulting firm, has compiled a comprehensive list of studies[18] showing biological effects at radiofrequency exposure levels far below what would be explainable as "thermic effects" and well within the range you are commonly exposed to every day.
Resonance intensifies biological effect. Resonance occurs when a form of radiation has a similar frequency as a body part. For example, microwave frequencies are similar to the frequencies of your brain!
Studies are typically done for short exposure periods, at higher intensities. Scientists claim that duration of exposure is equally important to intensity of exposure, but is often NOT studied, and that long-term, low-level exposure can have effects equivalent to short-term, more intense exposure.
The effects of radiation are cumulative. Your body becomes more sensitive to it over time.
There are no longer any control groups, since human beings are all now exposed to such pervasive radiation. Lack of a control group makes it even more challenging to conduct meaningful studies.

The point is, standing in your kitchen while your microwave is zapping your dinner, night after night, will not make you glow in the dark. But over the months and years, what is the cumulative effect on your body and health?

Why expose yourself to these potential dangers when there are safer alternatives for cooking available?

Is Microwaving Food Any More Dangerous than Heating it with a Conventional Oven?

Some experts claim that the effects microwaves have on molecules can all be explained simply as the "thermic effect" of heating—in other words, microwave cooking is no more detrimental to food than conventional heating.

They argue that, since microwaves are non-ionizing radiation, then it's impossible for them to damage your blood cells, or eradicate the folic acid in your spinach.

Others have proposed there is some sort of "microwave effect" that causes changes in the molecules in a way that conventional heating does not. For many years, the party line was that "microwave effect" is a myth.

However, study after study has resulted in evidence to the contrary, showing effects that cannot be explained away as simple thermal effects.

In a letter entitled "DNA and the Microwave Effect"[19] (sourced as Penn State University, 2001), the author reviews the history of the controversy surrounding the microwave effect and the research findings to date. He explains that, although fundamentals of thermodynamics and physics would tell you the microwave effect is impossible, studies keep turning up evidence of its existence.

Some of the main points made in the letter are the ***owing:

Microwave heating and conventional heating may appear identical on a "macro" level, but the two appear very different on a molecular level.
Microwaves are effective for sterilization, which has been studied for several decades. There is controversy, however, is about whether it's the heat they generate or if it's something else altogether.
One scientist (Kakita 1995[20] ) was successful in demonstrating that microwaves are capable of extensively fragmenting and destroying viral DNA, something that cannot be accomplished by heating alone.
Multiple studies offer evidence that there are multiple mechanisms for breaking apart DNA without ionizing radiation, but no theory currently exists to explain this phenomenon.

Some scientists are taking advantage of the microwave effect and using microwaves in the laboratory to greatly accelerate chemical reactions, sometimes by a factor of a thousand, resulting in the completion of reactions in minutes that formerly took days or months and a lot of toxic chemicals[21] .

This newly found interest in "microwave chemistry" has spurred skeptic scientists into taking another look at what microwaves actually do and how they do it.

Sometimes common sense trumps empirical evidence.

The Penn State letter/article said it best:

"...It would seem there is reason to believe that the microwave effect does indeed exist, even if it cannot yet be adequately explained. What we know at present is somewhat limited, but there may be enough information already available to form a viable hypothesis.

The possibility that electromagnetic radiation in the non-ionizing frequency range can cause genetic damage may have profound implications on the current controversy involving EM antennae, power lines, and cell phones."

No sé tampoco cuanto revuelo con el microondas (que lo utilizamos de ciento al viento) en comparación con toda la radiación a la que estamos sometidos diariamente sin darnos cuenta.

Desde ondas de radio y televisión, redes wifi (que además funcionan a la misma frecuencia que el microondas, los 2,4 GHz), telefonía móvil y hasta cableado eléctrico vario. Que vale que serán no ionizantes y que la potencia no será la suficiente, pero yo estaría más preocupado por eso.
 
no.

segun los articulos que he puesto . es peor el microondas porque desnaturalizaria los alimentos...

¿ Cuánta leche ? ¿ 10 litros ? ¿ 10 gramos ? ¿ Un vaso ?

Del estudio de Watanabe (http://lib3.dss.go.th/fulltext/Journal/J.agri.food chem/1998/no.1p1-360/1998v46no1p206-210.pdf):

Microwave Heating of Foods. Ten grams of raw beef (or
pork) was homogenized in 50 mL of distilled water at room
temperature using a universal homogenizer (Nihon Seiki
Seisakusho, Co., Tokyo, Japan). Each of the homogenates and
pasteurized cow’s milk (100 g) were placed into a glass dish
suitable for microwave cooking and treated for 6 min by
microwave heating. The microwave oven used was a Funai
(Tokyo, Japan) Model MO57-6A. The full power was 500 W,
and the frequency of radiation was 2450 MHz. Beef and pork
homogenates and cow’s milk without microwave treatment
were used as controls.


Que cada cual evalue la relevancia de este estudio (para lo que estamos discutiendo). Yo, desde luego, no tengo un vaso de leche (mucho menos 100 gramos) durante 6 minutos ni durante 3 en un microondas.
 
yo creo que esta claro que es nocivo aunque en cantidades infinitesimales , pero todo se va sumando ...

por que añadir un elemento mas de daño a nuestro organismo , por ahorrar tiempo ?

ademas la comida de microondas suele ser una cosa , no se calienta homogeneamente..

En el trabajo de mi marido, se comprobó que efectivamente calentar, cocinar con microordas desnaturaliza los alimentos, aparte de que todavía es muy pronto para saber si las ondas son perjudiciales para la salud. Parece ser que el mejor sistema es el gas, por delante de la electricidad. No sé en que se basan tales estudios, se lo tendría que preguntar a el. Nosotros no, no tenemos microondas.

Insisto en que tantos minutos para tan poca leche es una barbaridad. Yo apenas pongo un minuto para un vaso y ya está que trina.

Las proteínas, con el calor, se coagulan. Con microondas, con sartén o con lo que sea. Como ya ha dicho el conforero panqueue no tiene nada de extraño que el uso del microondas desnaturalice los alimentos, es que todos los métodos de cocción lo hacen. Se cocinan los alimentos para mejorar propiedades como el sabor o la digestibilidad y ya hace mucho que se sabe que en el proceso otras propiedades del alimento sufren (pérdida de vitaminas). Y si el microondas no se usa para cocinar sinó sólo para calentar no tiene sentido llevar el calentamiento hasta el punto en que la desnaturalización ocurra, igual que no tiene sentido decir que el microondas sí daña la comida de una forma que otros métodos no, o al menos esto no es lo que el estudio de Watanabe demuestra.

Citado por ti mismo:

Contrary to popular belief, microwaved foods don't cook "from the inside out." When thicker foods are cooked, microwaves heat the outer layers, and the inner layers are cooked mostly by the conduction of heat from the hot outer layers, inward.

Las microondas tienen muy poca capacidad de penetración en un alimento sólido. Un líquido se puede calentar a toda potencia y se calentará homogéneamente debido a las corrientes convectivas en su interior. O se puede remover fácilmente después de sacarlo del aparato para homogeneizar la temperatura.

Para calentar sólidos es mejor usar media potencia y ampliar el tiempo, de este modo el calentamiento es mucho más homogéneo porque el calor tendrá más tiempo para llegar al interior sin llegar a quemar el exterior. Si es posible, también ayuda remover el contenido del recipiente después de unos minutos y añadir unos minutos más.
 
Yo tengo una pregunta:

Hace tiempo, a mi progenitora se le rompió el cristal de la puerta del microondas. El cristal roto es el de fuera, no el de dentro, el que da al interior del micro, y que es que plástico creo y esta integrado en la estructura que da al interior del micro.
El micro es un Whirpool Vip 20, no hallamos recambio así que quitamos la estructura de fuera de la puerta, osea el plástico blanco que hacia bonito y a través del cual tirábamos para abrir la puerta y que sujetaba el cristal de seguridad, y dejamos entonces la parte de la puerta que da hacia el interior del micro.
Yo con esto de la radiación ionizante etc, me pregunto si el cristal roto de fuera protegía o solo era para darle un buen aspecto?

El micro sigue funcionando igual de bien, pero la puerta pues es la parte de color de plástico de dentro con la pantalla de plástico que lleva por dentro, que ahora se ve desde fuera. No se si me ejpliko.

No se si será malo tener así el micro.

Un saludo.

No he entendido muy bien lo que habéis hecho. Pero de todas formas la puerta lleva ese dieléctrico del que hablé, es muy conveniente que esté lo menos dañada posible. La rejilla ofrece bastante protección, pero aún así se añaden más medidas.

Un microondas no vale tan caro. Tener el micro con fugas supone mayor gasto de electricidad al no concentrarse todas las ondas en lo que se quiere calentar, es decir, se pierde eficiencia. También hay riesgo de quemadura.

Una cosa es la degradación por puro efecto termico como puede ser la desnaturalizacion de una proteina que no deja de ser un proceso puramente adiabatico, y la otra es que con microondas las sustancias a una temperatura dada no tienen porque encontrarse en su estado fundamental sino en estados excitados que acostumbran a ser mas reactivos....
Con lo cual el estado final no tiene porque ser el mismo al calentar un vaso de leche hasta la misma temperatura en microondas que en el fogon.
