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.

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.

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.

Monsanto’s latest marketing ploy: Labeling GMOs as “biofortified”

GMOs have been getting a bad name for quite some time now, and it’s hardly surprising given the near-constant stream of evidence showing the harms caused by genetically engineered crops and the pesticides used on them. As people increasingly make an effort to avoid buying these products, Monsanto has come up with a new idea to trick people into forking over their hard-earned money for its health-destroying products.

The Waking Times reports that Monsanto is trying to manipulate the definitions used on food labels in such a way that GMOs could be labeled as “biofortified foods.”

Codex Alimentarius is a collection of codes and guidelines created by the U.N. Food and Agriculture Organization to standardize world food trade and its production and safety. Codex was mulling a proposal to allow a company to use the term “biofortified” on vegetables that use conventional cross-breeding to increase the content of certain nutrients to help give malnourished populations a nutrition boost.

Monsanto sensed an opportunity here and set out to exploit it. They used their influence to try to convince delegates to have the definition of “biofortified” broadened to include foods that have been genetically modified. The National Health Federation (NHF), which is the only natural health advocate with a seat at Codex, reports that many of the delegates saw right through Monsanto’s attempt to pull the wool over consumers’ eyes, and the move was even denounced during the meeting. Nevertheless, the topic will be debated when the group convenes in Berlin this November under a new chairperson.

NHF President Scott Tips said: “It is a very sad state of affairs where we have come to the point where we must manipulate our natural foods to provide better nutrition all because we have engaged in very poor agricultural practices that have seen a 50% decline in the vitamins and minerals in our foods over the last 50 years. We will not remedy poor nutrition by engaging in deceptive marketing practices and sleight of hand with this definition.”
