Seems like French fries and potato chips will soon be health food items. But they will contain less acrylamide, a chemical shown to cause cancer in rats and mice. (Unless, that is, you decide you prefer home cookin’.

Several companies — Heinz, Frito-Lay, Kettle Foods and Lance Inc. (which makes Cape Cod chips) — have  agreed to lower acrylamide levels (wow finally!) in their foods to settle a lawsuit filed by the state’s attorney general in 2005. This is the latest in a number of developments stemming from that lawsuit: Last year, Wendy’s, KFC, Burger King and McDonald’s (ever notice it basically takes threats to get big corporations to do the right thing?) agreed to pay fines and label their products with a Proposition 65 warning — you know, those perturbing signs you run into in parking lots, dentists’ offices and by the specialty sodas in BevMo alerting you to some unspecified risk to your body or the body of your unborn child. And Procter & Gamble has pledged to halve acrylamide levels in Pringles to avoid having to label its products with a Prop 65 warning.

Acrylamide is formed when sugar and the amino acid asparagine react in high heat in what’s called the Maillard reaction, which always makes me think of ducks but was actually a chemical reaction discovered by the scientist Louis Camille Maillard. (It is what’s responsible for the brown crispy, tasty bits on roast meat.) One way in which acrylamide formation can be reduced is by kicking asparagine out of the spud — using an enzyme to convert asparagine into the related amino acid, aspartic acid.  (Companies are commercializing enzymes to do just that, with cute names like “Acrylaway.”) Exposure to other chemicals, such as various acids and antioxidants, may also help. Alternatively you could totally boycott these companies for using CHEAP products and MANIPULATIVE Advertising and SUGGESTIVE marketing to ENTICE you, me, everyone into buying this crap to begin with!

And from the other end of things, spud researchers have used genetic engineering to reduce the amount of sugar in potatoes. – Are you kidding me? LEAVE THEM ALONE!

Given the choice between fries with carcinogen and fries without carcinogen, I’ll take mine without, of course. But really, how worked up should we get about this acrylamide business?

First off, we’ve been merrily frying potatoes in our home kitchens for decades(hasn’t cancer rates exploded in the same time?!). Second, many other foods contain acrylamide — coffee and olives, to name just two. Third: Links to human cancer haven’t been established, and I’ve sometimes wondered what doesn’t cause cancer in a rodent if you toss enough at it.

Finally, fruits, vegetables and other foods naturally contain many chemicals that can cause cancer in high doses in rodents. Here’s a partial list, from a December 2005 L.A. Times article:  benzyl acetate, caffeic acid, coumarin, quercetin — found in such healthful, upstanding items as apples, basil, broccoli and tomatoes. You can read about that here. And if you want to read more about the acrylamide issue, go here.

When it comes to fried potatoes and giant bags of potato chips (even, alas, the limon-flavored ones, which are as close as I know to a perfect food, and I don’t intend to give them up), could one, perhaps, tentatively argue that the fat, calories and starch they contain are a greater risk to this country’s increasingly hefty population than acrylamide? I mean, if the U.S. Department of Agriculture ever decided to re-categorize potatoes as non-vegetables, the research would soon show we eat no vegetables at all.

I guess my two-cents is – Accountability and ethics in marketing these products may be in question here, isn’t it time to take action to be certain the very food you eat is actually healthy and these companies are REALLY doing what they claim they are? I sure the hell hope so. You know someone that has died from cancer?

Think about it.

Australian researchers have discovered a group of tiny little bugs that will eat up one of the most hazardous cancer-causing substances in a polluted environment and help save many lives.

They have been identified by Megh Mallavarapu of University of South Australia as native soil bacteria that destroy a group of chemicals known as BTEX, linked with cancer, nerve damage and other diseases.

Fuel leaks are one of the most widespread forms of contamination in Australia and elsewhere,” Mallavarapu explained. “Former service station sites, fuel farms, garages, workshops, gasometers, oil spills, which used or processed hydrocarbons or explosives, are literally everywhere that has been closely settled for the past century or so.”

Mallavarapu made these presentations Sunday at the 5th World Congress of Environmental Toxicology and Chemistry (SETAC) here.

He explained that in the course of his research into groundwater contaminated by petroleum and oil spills, he identified a number of indigenous soil bacteria that appear highly tolerant to BTEX – the deadly volatile organic compounds benzene, toluene, ethyl-benzene and xylene.

Of these, benzene is a known carcinogen, and the other three can have serious effects on the central nervous system. Besides polluting water and soil, these chemicals can sometimes emerge from the ground as vapours, being inhaled by people living and working nearby.

Bacteria which can tolerate BTEX have been identified in other parts of the world, but these are the first from Australia to show a specific preference for dining on these hazardous wastes.

The microbes devour the carbon in the BTEX molecules, breaking the rest down into simple and harmless constituents of carbon dioxide and water: “You just add the bacteria to BTEX-contaminated water – and they go straight to work.”

However, Mallavarapu and his team have taken the work an important stride further, isolating and sequencing the actual genes in the bacteria which degrade BTEX.

Knowing what genes to look for will help in widening the search for more kinds of soil organisms which have a preference for dining on toxins, or identifying strains which do so even more efficiently.
