What is Irradiated Food and Why Should I Avoid It?

Marygrace Stergakos — Tue, 21 Jul 2009 12:58:44 +0000

If you’re a Whole Foods shopper who occasionally peruses the market’s free pamphlets and brochures, you might know a thing or two about the dangers of irradiated food–at least, that’s where I learned about it. We hear a lot of talk about harmful ingredients: dyes, preservatives, trans fats, and HFCS, for instance, but little is mentioned about this equally harmful process that can alter the molecular composition of the food you eat, damaging valuable vitamins, minerals, and enzymes, all in the name of making said food safer.

During irradiation, food is exposed to ionizing radiation in an effort to destroy microorganisms, viruses, bacteria, or insects that could be dangerous if consumed by people. In addition to sanitizing our food, irradiation can also be used to prevent sprouting, delay ripening, or increase juice yield–in other words, messing with a fruit or vegetable’s natural life process or progression. How exactly does irradiation achieve all these things? By damaging the DNA of the food in question, basically stunting any growth.

Considering how much time and effort is spent attempting to halt or reverse DNA damage to our own cells, then, it’s ironic that more attention isn’t paid to the process of food irradiation. We’re constantly told to eat more fruits and vegetables because they contain antioxidants, the things that fight free radicals (which are responsible for oxidation and thus, cell damage!) However, the vast majority of produce in this country is irradiated, therefore containing the very stuff we try so desperately to avoid!

Pretty strange, huh? Behind the jump, there’s a bunch more reasons why you should avoid irradiated food.

Genetically Engineered Viruses Remove Trace Metals

Amiel Blajchman — Sun, 05 Jul 2009 03:16:34 +0000

University of British Columbia Professor Scott Dunbar of the school’s Norman B. Keevil Institute of Mining Engineering has pioneered a way to genetically engineer viruses to bind with minerals.

Along with colleagues, his team has developed a method to selectively “breed” a viral family to bind to specific minerals. In other words, they are developing viri that can find and bind to a chosen mineral in a sludge pile!

Food Policy Friday: FDA to Conform to EPA Standards for E.Coli in Bottled Water

Gina Munsey — Fri, 05 Jun 2009 17:55:00 +0000

Drinking water poses a threat due to possible perchlorate contamination and BPA leaching from plastic, but it seems reasonable to assume that in the United States, bottled water is free from fecal matter. Yet until now, there were no requirements to test source water — 70% of which comes from the the same place as tap water.

Beginning December 1st, “bottled water containing E. coli will be considered adulterated,” says the US Food and Drug Administration. You don’t say? It doesn’t seem as though we’d need a press release to tell us that, but this is the FDA we’re talking about.

Vitamin B12 Could Be Cure for Widespread TCE and Perc Contamination

Tina Casey — Tue, 19 May 2009 02:30:42 +0000

Mom always said to take your vitamins, and now it looks like she was right. A good dose of vitamin B12 could be the key to cleaning up thousands of sites contaminated by solvents, particularly industrial degreasers and dry cleaning chemicals known as trichloroethylene (TCE) and tetrachloroethylene (perc). These are two of the most common ground contaminants in the U.S., and when they get into aquifers, they are among the most difficult to remediate. All that may be about to change.

Cattail Army Deployed to Fight Water Pollution

Tina Casey — Sat, 16 May 2009 14:18:08 +0000

The lowly cattail is emerging as the weapon of choice against water contamination, and perhaps even global warming. In addition to its use in large phytoremediation projects to absorb contamination from groundwater and wetlands, the cattail could also work in on a small, inexpensive scale, helping to reduce arsenic contamination in impoverished areas. All this and biofuel, too?

30% Ocean Mercury Rise Linked to Asian Coal Plants

Michael Ricciardi — Sat, 16 May 2009 07:19:56 +0000

World wide, 75 percent of human exposure to mercury is from the consumption of marine fish and shell fish. In the U.S., about 40 percent of all human exposure to mercury is from tuna harvested in the Pacific Ocean, according to Elsie Sunderland, a coauthor of the recent US Geologic Survey study.

Data used in this study comes from one of 15 (so far) research cruises that are part of a much larger, international project called CLIVAR; the Climate Variability (CLIVAR) Repeat Hydrography/CO2 research program.

Data analysis of the water samples indicated that total mercury levels in the North Pacific Ocean water have risen about 30 percent over the last 20 years.

Pistachio Recall - is Anything Safe to Eat Anymore?

Amy Bell — Wed, 01 Apr 2009 16:37:32 +0000

After my family and I enjoyed several handfuls of pistachios at a get- together last weekend, I was surprised to hear yesterday about the latest food recall.

Federal food officials are warning Americans to avoid any food containing pistachios because of possible salmonella contamination. (Just like the recent problems with peanuts.)

All of this food recalling makes a person wonder if anything is really safe to eat anymore?

African Diamond Miners Choosing Carrots Over Carats

Bryan Nelson — Wed, 18 Mar 2009 06:13:39 +0000

Finally, some good news to come out of the global recession! As the price of rough diamonds plummets in Africa, miners throughout the continent are instead turning toward a future in agriculture.

Diamond mining has nearly destroyed many African nations. In Sierra Leone, for instance, diamonds are what fueled an 11-year civil war, which killed or injured nearly 100,000 people and displaced millions. The conflict was popularized in the Oscar-nominated blockbuster film, Blood Diamond, starring Leonardo DiCapprio.

Oil Thieves Steal $1.5 Billion Yearly in Nigeria

Jake Richardson — Tue, 10 Mar 2009 20:38:52 +0000

A director of the Shell Petroleum Company in Nigeria revealed at a conference that oil theft is costing the company and the country tremendously.

“Even with low oil prices, the (Nigerian) government loses between $1 billion and $1.5 billion every year to crude theft,” Mutiu Sunmonu said at the Abuja conference. Nigeria is one of the top producing oil nations in the world with hundreds of miles of oil pipes used for transporting crude.

14,000 Barrel Oil Spill in Ecuador’s Amazon Rainforest

Jake Richardson — Fri, 27 Feb 2009 01:54:21 +0000

In the Napo region of northeast Ecuador, the nation’s second largest oil pipeline leaked tens of thousands of gallons of crude oil.

The pipepline company’s website described the leak as being due to ‘natural causes’.

American environmental scientist Douglas Beltman witnessed the amount of oil in the Santa Rosa river in the area and was quoted in a Reuters update, “The river was completely covered with oil from bank to bank.” (Mr. Beltman was generous enough to provide some photos taken of the spill for this story.) About 100 workers are cleaning up the area and a spokesperson for the pipeline company, Oleoducto de Crudos Pesados Ecuador, said the leak had been contained.

Swedish Antibiotics Could Spawn Drug-Resistant Bacteria in India

Bryan Nelson — Sun, 08 Feb 2009 12:38:35 +0000

Research from the University of Gothenburg has revealed that 31% of antibiotics sold in Sweden contain drugs manufactured near Hyderabad, India, where porous wastewater treatment has led to widespread contamination.

The questionable water treatment facilities were found to release levels of the antibiotic ciprofloxacin which were 5 times higher than the daily consumption of the entire country of Sweden. At levels that high, there is an increased risk of breeding “super germs”, drug-resistant bacteria which have evolved an immunity to antibiotics.

Melamine found in Milk Powder: Infants get Kidney Stones One confirmed Death

Jessica Gottlieb — Sat, 13 Sep 2008 20:25:25 +0000

According to the AP Newswire 432 children in China have been sickened by infant formula tainted with Melamine.

There is one confirmed death.

Apparently, a Chinese dairy that sold milk powder linked to kidney stones in infants knew it contained melamine. They failed to recall the tainted milk products because, “grocers wouldn’t return it”. Uh, okay? I kinda don’t get that either.

In any event. If you or anyone you know and love shops at an ethnic market with any regularity (I do!) please pass this important information along. Although much of the tainted formula has been seized, and many executives are in custody (Yes they did this on purpose) some might have made it’s way to other countries.

Iowa Flood Waters Contaminated

Sarah Pressman Lovinger — Wed, 02 Jul 2008 13:21:07 +0000

I am still waiting to hear back from a spokeswoman at the USDA to find out the answer to the question I posed last week: who is in charge of protecting us from crops affected by flood water? In the meantime, I got an alert from the Centers for Disease Control about contaminated water in Iowa. I can tell you, dear reader, that while you may not want to eat food grown along flooded riverbeds, you most definitely do not want to walk in that water, particularly if you have open sores or cuts on your feet and legs. Exposing a sore on your skin to contaminated water puts you at risk for a nasty infection.
