Allergic reaction to the products of introduced gene products (the ‘foreign’ genes)  is one of the primary concerns about GMO’s.  It is a concern that is legitimate, but, like “unknown consequences” needs to be put into perspective of the non-GMO food we eat every day.

Fanatic Cook (among many others) has been writing about it.  Bix links to a very helpful monograph on the subject of allergenicity in GMO foods. Predicting allergic potential is difficult and an inaccurate process, at best.  All genes used in GMOs at least go through screening for potential allergenicity.  Compare this to the vast majority of other foods that are effectively only screened on people through trial and error through a long history of eating.

The main reason the use of GMO grains is not required to be listed on labels is that the grains are not any more likely to cause allergies (or any other adverse affect) than their  non-GMO counterparts.  Voluntary labelling such as “no-GMO” is allowed, which is something I applaud and support in the interest of freedom of choice and information.

I’ve been asked if eating meat from animals fed GMO grain means that we are eating the GMO proteins themselves?  Only to the extent that the particular modified protein passes through the digestive system wall.  In a healthy animal, most proteins are broken down before they are passed into the blood.  If this were a concern, we should be far more concerned that my pasture-raised cattle graze ragweed and other highly allergenic plants.

Since last month’s post on the role of technology in feeding the world, I’ve been thinking a lot about the fundamental issue of GMO’s.

A primary GMO-related fear is the unknown consequences of the genetic manipulation.  I won’t discount this concern, but I would like to put it into perspective.

Every bit of variation in all the food crops (plant or animal) we consume arises by genetic mutation.  As humans domesticated plants and animals, we selected mutants (sounds a lot scarier than ‘variants’, doesn’t it?) that suited our needs better.  These mutations had some visible difference (color, faster growth, better taste), but beyond what we could see, we had NO idea what other changes were caused by the mutation.

Since early in this century, plant breeders have produced new varieties of all sorts of plants by something called “mutation breeding“.  Seeds are subjected to some form of mutagenizing agent, such as a chemical, UV light or x-rays.  Thousands are planted to screen for and select desirable mutations.  This is a primary way in which disease-resistant varieties of vegetables, fruits and other crops are developed.  The FAO maintains a database with thousands of catalogued varieties.

Even heirloom varieties are mutants.  Are you familiar with those cool zebra-striped heirloom tomatoes?  Those stripes are caused by a “jumping gene” that randomly inserts itself in the genome, sometimes disrupting a color gene.

At least the GMO varieties had to go through some sort of characterization of their biochemical properties.

We’ve blogged about home food safety here more times than I can count.  It hit home (literally) last night.

My boys go to a Montessori school where they have access to a kitchen.  Lunch is truly part of their curriculum, a place where they discuss nutrition, recycling and also honor healthy food and communal dining.   They are encouraged to bring “oven food”, in glass containers or wrapped in foil to heat up in the oven (no microwaves allowed) so they can have a hot lunch.  As a sidebar, it is very gratifying to have your children choose a bowl of homemade beef stew for lunch over PB&J!

Yesterday’s lunch was “stuffed hamburgers”.   My son forgot to put his dish on the oven tray at lunch time for heating, so was not able to heat it up.  He chose not to eat it cold (can you blame him?), but apparently go hungry about 3 pm between the end of school and start of his afternoon Performing Arts class, so ate his now 8-hour old, non-refrigerated hamburger. I’ll spare you the details of what happened when he got home about 6 pm.

This was our home-grown beef, ground and frozen straight from a USDA-inspected carcass at a plant whose cleanliness I see with my own eyes each month.  The meat was cooked properly and placed in the refrigerator immediately after we finished our supper.  My son has a very sensitive palate–often declaring the milk to be ‘off’ days before the rest of us suspect anything.  He said the burger was delicious.  The failure here was that he has an uninsulated lunch box, so foods like leftovers and sandwhiches should NEVER be eaten if not consumed at lunch.

Fortunately, the onset of what I can only attribute to food poisoning was so rapid that Eric does not seem to be suffering any after effects this morning.

I think when he gets home from school today we’ll  be making an online visit to the FSIS’s mobile food safety game.

Halloween Junk Food at Whole Foods: My friend, Dr. Rita-Marie, is fired up (read that po’d) that Whole Foods is pimping white flour, white sugar, food coloring-frosted cookies as Halloween Treats.  So much for “nutrients intact, as nature created” (the supposed Whole Foods motto).

Food Safety Gone Astray: A November ‘teach-in’ about how recent changes in agri-business practices implemented in the name of “food safety” have had harmful environmental effects.  In particular, changes in production after the e-coli-in-spinach outbreak may have negative effect on wildlife with dubious value to food safety.

I’ll let you in on a special Halloween secret that has saved many a tussle over too much Halloween candy at our house:  The Tooth Fairy is the Great Pumpkin’s sister. Not many people know this, but the weekend before Thanksgiving, if children leave their uneaten Halloween candy outside the bedroom door, the Tooth Fairy will come take it and replace it with a coin for each piece.  She usually leaves bigger coins for the big stuff! [note of guilty admission; she leaves the most for the stuff Mom especially likes]

Let your kids know ahead of time, and you’d be surprised how much easier limiting their sweet intake is!  My kids make candy cities and candy castles with their haul, but they show remarkable self-control over how much they eat, because they also compete on who has the most savings in their savings accounts.

Ladies — here’s a verified warning from my PTA listserv.  Sherwood brand Pirate’s Gold Milk Chocolate coins are being recalled by the Canadian Food Inspection Agency because they contain Melamine, the ingredient that has caused many infant deaths in China.  These candies are sold at Costco and many bulk and dollar stores.  Please check your children’s Halloween candy and DO NOT LET THEM EAT THE PIRATE COINS (those wrapped in the shiny gold foil — picture below).  Please let other parents know about this!

OH FOR THE DAYS WHEN PIRATING WAS SAFE!!!!

According to a study released by the Environmental Working Group, bottled water is no better than filtered tap water, despite being considerably more expensive (not to mention the carbon footprint of bottles and transportation, or the reports of phlalates from the bottles!).

• Many bottled waters use municipal water sources that have been filtered or otherwise purified.  As much as I complain about Cameron, TX tap water, I’m not sure I’d rather be drinking water from Las Vegas or Houston.
• Bottled water manufacturers are not required to disclose test results for contaminants, unlike municipal water.  The report showed that faith in bottled water purity is not always well-founded
• The same chemical profile is found in many bottled waters as in tap water.  Those images of mountain springs don’t have much to do with the source or the purity.

I geeked the study, and it passed the transparency test of having the actual data available.  Although somewhat alarmist in its executive summary, the basic truths have not been twisted.

The bottom line:  You are better off financially and environmentally buying a good water purification system for your own tap water.

The New York Times recently published an open letter by Michael Pollan to the next “Farmer in Chief”.  It begins:

It may surprise you to learn that among the issues that will occupy much of your time in the coming years is one you barely mentioned during the campaign: food.

Although we don’t think about it too often, our food production system is inextricably linked with health, climate change, use/dependence on fossil fuels and economics.

Some of my favorite points in the letter:

• Cheap food  that is highly processed, high fat and/or highly sweetened has hidden costs in an increase in partially preventable  illnesses, such as obesity, heart disease, type II diabetes.
• New policies in food subsidies should promote healthy food choices, local economies, diversity and quality over quantity (as measured in calories).
• Conservation is not an either/or proposition relative to food production.  We can produce food in ways that have minimal, or even beneficial effects on the environment.
• Farmland preservation and support of more of our population making a living at agriculture are critical to a healthy food system.  This means training and incentivising young farmers.
• Decentralizing food production will get more people in touch with where their food comes from.  Consumers that really understand food production are less likely to make unreasonable legislative demands and more reasonable diet choices.
• The new first family should establish their own “Victory Garden” on the South lawn of the White House.
• Lunch needs to be an educational part of the school day.  We need to raise kids that can make good food choices and  know how to cook.

We touched on this same topic earlier in this blog.  Most of all, I agree with Pollan that the food crisis paired with our energy costs presents an exceptional opportunity for real reform.

Kids cereals still too sugary.  According to Consumer Reports, 11 top kids cereals have as much sugar as a glazed donut, and two are more than 50% sugar by weight.  Best bets for fiber and low sugar? Cheerios, Kix, Honey Nut Cheerios (all General Mills), and Life (Quaker Oats).

 The Organic Milk Debate: Is big the same as bad? Consumers and activist groups are saying yes.  Do industrial-scale organic farms violate the intentions of the organic laber, or is it the next step in bringing organic to the masses?

Eating Healthy on a Budget:  Lots of links and tips in this post from BlogHer.  I’m still a fan of more fresh, less processed, more home-grown and home-cooked.

Bill of Rights for Young Athletes.  From Arizona Mama.  Not food-safety related, but relevant to all of us who have school-age children involved in athletics or any other myriad of activities.  Hitting home for me in particular is every child’s right (athlete or not) to be treated with dignity.

Yo-Yo powered i-phone charger.  From Ecogeek.  Several times cooler, more convenient, and better for the environment than a solar powered charger.  Not sure you’ll be seeing this one the market any time soon, but it’s a fun idea!

Although parents play a key role in ensuring that the food our family eats is safe, kids need to know about food safety too.

Here’s some things kids can do (along with the whole family):

Wash and Dry your hands before you make or eat a snack or meal.

Put back packs on the floor, not the counter (or desk or other eating surface).  Same goes for purses, btw.

Put foods like milk, yogurt, lunch meat and eggs back in the refrigerator right away. 

Use separate cutting boards for meats versus fruits and veggies.

Use ice packs in lunchboxes and picnic baskets. Throw away uneaten lunch box leftovers.
