Some foods trap electromagnetic radiation when microwaved: Scientists discover why grapes produce fiery plasma when “nuked”

From NaturalNews …. I’m sure most of our readers wouldn’t be using one anyway … important info to pass on to the uninformed.

(Natural News) It’s a cool party trick, a staple at science fairs and is commonly demonstrated on the Internet: If you slice a grape almost in half and then put it in the microwave on full power, you can create a pyrotechnic spectacle as the area where the two halves of the grape meets bursts into flame.

Scientists used to believe that this phenomenon took place because the piece of skin holding the two parts of the grape together was acting as an electron conductor, but new research has uncovered a completely different explanation.

A study conducted by researchers from Trent University in Canada, published in the journal Proceedings of the National Academy of Sciences of the United States of America(PNAS), has found that this phenomenon actually occurs when microwave radiation is trapped inside cavities in the grape halves. (Related: Microwave ovens — the curse of convenience.)

An “Ielectronternet parlor trick” explained

As reported by New Scientist, microwaving grapes in this way creates a plasma. Whenever a gas is heated and ionized it creates plasma which releases electrons. Based on this fact, scientists assumed that the piece of skin holding the two halves of the grape together was acting as a conductor for these electrons and creating the fiery show. However, the new research discovered an entirely different explanation.

New Scientist explains:

Aaron Slepkova at Trent University in Ontario, Canada and his colleagues decided to study the phenomenon using thermal imaging and computer simulations. They found that the grapes were actually trapping the microwaves inside them, which led to them heating up.

Mother Nature’s micronutrient secret: Organic Broccoli Sprout Capsules now available, delivering 280mg of high-density nutrition, including the extraordinary “sulforaphane” and “glucosinolate” nutrients found only in cruciferous healing foods. Every lot laboratory tested. See availability here.

The team used thermal imaging to look at whole grapes sitting separately, and found the energy was focused in hot spots at their centres. This suggests microwaves were being trapped inside a ‘cavity’ in the grape.

Thomas Volz of Macquarie University in Sydney, an expert who was not involved in this particular study, explained the process in more detail, as further reported by New Scientist:

Volz says that when the grapes are almost touching, they can exchange energy. These hot spots begin to build up between the two grapes and the microwaves interfere with each other to form a much hotter and more energy-dense spot than they would form independently.

Placing them next to each other focuses the energy into a very small spot, which is enough to ionise sodium and potassium within the grapes and ignite the plasma.

Could this trapped microwave radiation be harmful?

The scientists replicated the experiment in other items, including hydrogel beads, gooseberries, blackberries and quail eggs. Basically, any grape-sized object that contains enough water will create the same fiery effect when heated in the microwave.

This begs the question: Is microwave radiation being trapped in other foods heated in the microwave? And, does this food become harmful to humans when this process has taken place?

The researchers did not address this issue in their findings, but it is interesting to note that microwave manufacturers are quick to warn that old microwaves that leak radiation should be discarded because they become dangerous.

And studies have found that being exposed to radiation by standing within three feet of a microwave oven can cause blood sugar spikes, heart palpitations, electrohypersensitivity and other problems.

Microwave ovens ‘fluke’ your heart while they ‘nuke’ your food – alarming studies reveal microwave frequency radiation can affect heart and blood

Such harmless benign looking little appliances, and so handy for our insanely sped up nowadays world. I’ve been laughed at for suggesting microwaves are harmful … that Russia banned them at one stage … thankfully the science is emerging. I first learned of the health risks from a nurse who was told in training (UK) not to heat baby formula in a microwave as it kills certain vitamins. From that I smelled a rat as the saying goes. Turns out a man who researched them by testing for vitamin content in food cooked in a microwave & food not, that definitely they do kill your nutrients. Needless to say his research was quickly debunked & hidden a long way under the proverbial carpet. Enough to put me off using one anyway. Err on the side of safety surely. I know a few folk who don’t use these anyway & I haven’t owned one myself for a few years now. As always you need to find this information out for yourself. Mainstream won’t tell you any time soon. It means fewer sales, less profits and so on. Because as you’ve possibly noted lately, for the last decade or more, that profits are more important than you or your health.

(Natural News) Many health conscious consumers rarely, if ever, microwave their food anymore, but when they do, they probably do not realize that they’re not just destroying the nutritional value of the food, but the “nuker” is negatively impacting their hearts.

The typical microwave frequency radiation coming from “nukers” seen in the average American kitchen is more than enough to screw with your heart rate and your heart rate variability. In fact, just 2.4 GHz, the average frequency produced by microwave ovens (and WiFi routers, by the way) can cause immediate and drastic changes to the human heart.

According to Dr. Magda Havas of Trent University, people exposed to radiation for just three minutes at 2.4-GHz can experience severe reactions in heart rate changes and altered heart rate variations, indicating an alarm response to stress, also called electrohypersensitivity (EHS) or rapid aging syndrome. This has been studied for decades. The response includes heart palpitations, clumping of red blood cells and fluctuations of the parasympathetic nervous system typical of a “fight-or-flight” response.

Dr. Havas also revealed that microwave ovens can lead to blood sugar spikes connected with diabetes. This usually happens when people stand within three feet of the oven while it’s running, like when anxious eaters park themselves directly in front of the microwave oven while waiting for those last few seconds to finish “nuking” their food or beverage.

Unequivocal evidence that microwave frequency radiation affects human heart

For years, bogus research and microwave oven fanatics have claimed that microwave ovens do not produce any immediate biological effects because the ordinary household level is far below federal guidelines. Most of those studies were conducted prior to the new millennium, but now environmental radiation is coming at us from multiple sources, including electromagnetic devices, laptops, WiFi and mobile phones.
