...that's apparently what they are calling it now! This video clip gives cooking tips and recipes for Asian Carp. Here, as in many places the argument is that if there is a market for eating them, perhaps that will control their populations.
Is it an odd sort of situation where from a biodiversity conversation standpoint ideally these creatures would be unsustainably/overfished!?

The Lives of Squid (a la "Green Porno")

Last week during our discussion of contested ecology of cod, seals, and fisherman in the North Atlantic one other species made an appearance: the squid. One big question was what their role was in accounting for the dynamics among populations of cod in the ocean...but then the squid-topic elusively swam away from us.
Isabella Rosselini's "Green Porno" series has been exploring the lives of creatures for three seasons now, but this last one has featured a bit of a twist by including the human food ecology context for organisms such as the shrimp, anchovy, and squid in here "Bon Appetit" series.
Check them all out, but the SQUID one is particularly interesting in the context of overfishing, ecology, and energy use on a global scale.
enjoy!

"Got Milk?" (how exactly do we get it...?)

---Major new outlets are paying attention the the questions of food production like never beofre, and especially the conditions under which most of our food is produced on an industrial scale for the sake of lower cost. CBS News has been running a series, and now ABC News is getting into it as well with this exposé on the treatment of dairy cattle at a farm in upstate New York. (the video is somewhat graphic, so be warned)
The growing awareness of the conditions under which our food is produced and the concerns it raises for food safety, animal welfare, and workers rights (different focuses depending on the reporting) is remarkable, and gives all all a lot to think about more carefully.
The image included here is from the Kids Page of the Tongala Dairy Industry's website called "Golden Cow." (Tongala is in Australia). The image does a good job of illustrating the factory nature of much milk production.
The Kids Page incidentally also has a lot of coloring and word find activities if you want to take a break from making art!

Eating our Way to Ecological Conservation? (the Asian Carp)

If you've been paying any attention to the news lately, you've heard of the current panic over the possibility of the invasive Asian Carp infilitrating from the Chicago Shipping Canal into Lake Michigan.
Starting in the Mississippi River, the state of Michigan just sued in federal court to force Illinois to close the canal as a mean to keep the carp out, for fears that once they enter it will completely crash the Great Lakes ecosystem worse than any of invasive in the history the lakes.
Some worry it is simply inevitable. Others are wondering whether perhaps there fight by a culinary means to intervene, at least in part: eat them!
It's unclear that these fast growing and voracious fish are actually that tasty, but chefs are trying to convince us otherwise, at least on a nutritional basis:
"[It has] 70-percent more Omega-3 than in catfish and tilapia," an animated Parola told an assembled crowd at his booth. "No mercury because it's a filter fish."
Parola was talking about the Asian Carp-- a slimy, boney fish that breeds quickly and is widely considered a pest. Parola's message: Eat the carp. Save the Great Lakes."
hmmm... or "mmmm!" (?)But seriously - this is no doubt one of the most serious ecological challenges to the U.S. currently; the videos below are "must see"

Eating Spiders in Cambodia
I came across this clip while searching for strange foods. I would say i am willing to eat almost anything and everything, but this i am sorry to say does not make my list. Tapping into my fear of spiders watching it brought out a true sense of horror. With some many things we eat they no longer retain their original form, but here the spiders look exactly the same. I will say what i do love is seeing the moment when even a man from the same culture has no interest in eating this delicacy. It makes me wonder about the lost traditions in food as things such as canned goods, and more processed food sources became the norm pushing out traditions in cambodia's culinary history. What do you think, and would you dare to eat this?

USDA Ruling
The USDA posted its final ruling regarding access to pasture for organic livestock operations.
Apparently it is a major victory for organic consumers, the integrity of the organic label, and the lives of organic livestock (according to Whole Foods).
The ruling and its explanation is on the USDA website.
The statement mentions something about "finish feeding" and I was wondering if anyone knows what that is?

In thinking about all those crawling things we might call food, the "cons" most also be consider with the "pros"
In this short report they discuss the risks of reptile eating in the context of the global food system (it isn't just beef, pork, and chicken anymore!):
"Some countries use turtles, crocodiles, snakes and lizards as a source of protein in the human food chain. Frozen imported meat from crocodiles, caimans, iguanas and pythons can be found in the EU"
Maybe not surprisingly, freezing and proper cooking is key.

Eating the Six-Legged
A promise is a promise, and I swore to the class last semester I'd eat the giant Thai water bugs I bought at my neighborhood grocery (discussed in originally in this post).
I can't say I was looking forward to this meal per se, but I wasn't too apprehensive either. Being a New England boy, I love shellfish, and so shell-on shrimp, lobsters, and full-bellied clams all taste good to me. How different would this be? So I went with that culinary theme and decided to go with the Deep-Fry option , having it be part of a side dish to my lunch:


Am I feeling squeamish, or focusing with laser-like attention
on my palate? You be the judge.

I have to say, it wasn't at all what I was expecting. The texture was crunchy and a bit scaly (I anticipated that), however the flavor was odd ~ it was like an aromatic blend of banana leaves and something else I can't put my finger on - somewhat nutty, almost like a pungent jasmine, and VERY salty. All that said, I can't say that it was tasty, at least not the way I prepared it, the novice that I am.
One thing I marveled at was the meat inside the thorax, clearly these guys fly a fair bit as their flight muscles were bulky and fleshy the way you see in dragonflies, in fact, you can actually make it out by texture distinctively as meat:

I didn't end up eating every last bit, but gave it a good "college try" as they used to say. Some parts were just a little to chitinous to manage....

Ramen-rific

Any of you who have had the luck to travel to Japan may now just how obsessed the country is with ramen, that lovely Chinese noodle bowl dish.
This past week the NY Times had a nice and reeeeeally extensive feature of the ramen chops and culture of Tokyo. Imagine entering a shop....
"From then on there is only one sound — the slurping of noodles. Oh, it’s punctuated by the occasional happy hum of a diner chewing pork or guzzling the fat-flecked broth, or even by the faint chatter of the chef’s radio, but it’s the slurps that take center stage, long and loud and enthusiastic, showing appreciation for the chef’s métier even as they cool the noodles down to edible temperature."

Bluefin tuna ban? Japanese sushi chefs likely to cry.....

A few months back I posted about the apparent failure for European countries to come to any real agreement on addressing the rapidly dwindling (perhaps to soon extinction) blue fin tuna populations of the Mediterranean.
Fished aggressively and largely for the Japan sushi market (supposedly the destination for 80% of the catch which prizes the fatty belly meat), things looked grim last fall as no one (Italy, France, and Spain included) was willing to put even a temporary ban on fishing these creatures in hopes of letting the population rebound.
Now Prince Albert of Monaco (click to see this dashing fellow) is leading the charge, and apparently with some success with moving toward a ban in the near future, as the New York Times reports. Of course the fishing industry is not happy, not even the US industry since bluefin is also found in the Atlantic:
The United States fishing industry is “strongly opposed” to listing the fish under the endangered species convention, said Rich Ruais, executive director of the American Bluefin Tuna Association, who said the trade ban “would create a huge black market.”
“In fact,” he said, “we believe a listing has the possibility of doing more damage than good.”
Which all begs the question of economics. But also the willingness for the fish industry to actually enforce itself.
Of course the question of what sustainable fishing and sustainable fish eating is at the enter of it all. The site Sustainable Sushi is a nice place to explore some of these issues...

Agave Nectar: Good or Bad?
I found an interesting article on agave nectar posted on the Food Renegade blog. Agave has been touted as a "natural, raw, or organic" sweetener, and safe for diabetics because its low on the glycemic index. Apparently it has a higher concentration of fructose than HFCS (high fructose corn syrup)! The post explains how agave is made and a bit about fructose as well.

Pets worse than SUVs for the environment...?

In a new book, two scientist claim "yes" - and it comes down to the particulars of the ecology of food and trophic levels. ABC News reports that the new book "Time to Eat the Dog? the Real Guide to Sustainable Living" is causing a stir, but environmentalists like Lester Brown explain:
"Dogs and cats are carnivores so they consume meat, which means they live rather high on the food chains." "Much higher than the typical person in the sense that most of us -- even those who are omnivorous -- eat a lot of fruits and vegetables and cereals and other things."
Of course, being critical of "man's best friend" can cause its own controversy:
"I think the first instinct should be to look at our own diet and not push off the global warming causes to domesticated animals," Pacelle told ABCNews.com. "If this is their primary thesis, it's an example of over magnified concern and we need to look to our own behaviors, not just energy consumption and transportation, but also our diet."
But isn't our diet their diet? We are co-domesticates, after all.
Of course certain nasty and daft habits increase that carbon footprint even more...!

Ghastly! Poisoning the river to rid Asian Carp

I peeked over at my neighbor's RedEye in the El today. A man-made Chicago waterway was poisoned to get rid of the invasive Asian carp species (remember them?).
"The fish has entered the Chicago Sanitary and Ship Canal — a man-made link between the Mississippi River system and the Great Lakes — and is knocking on the door of Lake Michigan. Once inside a Great Lake, the carp would have free rein in the world's largest freshwater ecosystem, imperiling the native fish of the lakes and a $7 billion fishing and recreation industry."
But so far, all the dead fish (90 tonnes expected) that have floated to the surface of the water have been native carp and shad. The toxin used is a naturally-occurring toxin that prevents fish gills from absorbing oxygen. The dead fish will be collected and dumped in a landfill. I imagine that it must be a horrible sight.
While it seems like a necessary step to remove the Asian carp from the system, I wonder if the disappearance of the other native fish in this canal will have any effects on the ecological system.

The GMO Debate - Your point of view?

Ok, so that was a good debate in class! But clearly we didn't have the proper amount of time to discuss it all as we should together, which is a shame the GM food issue is so critical.
So: I want us to continue the conversation over the next two weeks on our blog! How would you address the resolution yourself personally?
I am asking everyone to post their personal reflection on the issue here. In the comment line of this post.
You can come down one side or another, but you can also be undecided or less black and white. Wither way, please say what you are thinking and WHY. What arguments and rationales in the debate do you find most or less compelling? If you are Pro or Anti, what concerns on the other side might be legitimate (but in the end may be of low priority to you or perhaps fixable?)
Or, perhaps the resolution itself is poorly formulated and leads us to oversimplifying conclusions? What is a better way to think about the issue? What questions still remain that need to be answered?
Write to out here thoughtfully and drawing from all the various forms of arguments and evidence we've come across (I'd say a minimum of 150 words). Please sign your name too so we know who's thoughts we are reading!
As a consumer, voter, and cultural producer it is important to have a point of view on GM as it is likely to only between a larger issues in the years to come in our daily lives and globally....
Resolution:
The risks of GM foods outweigh the purported benefits and should not be allowed to be sold and planted.
Meanwhile, feel free to continue posting to blog items of relevant and interest!

Another Scary Monsanto Video!
Tuna fishy...

With Atlantic tuna population estimated to be at only 15% of its pre-industrial levels and worries are that our favorite fish is reaching the end of its (fishing) line according to a recent report.
The organization that is responsible for protecting this valuable fish stock, the International Commission for the Conservation of Atlantic Tunas, has apparently wimped out on the best strategy for preserving them: rather than put a temporary ban on the catching of this lovely and tasty fish, ICCAT decided to go the route of lowering catch quotas by 1/3, a measure many say is not only largely unenforcible, but will likely increase illegal fishing of prized catch.

This report dovetails with the class reading on the USDA ruling on Monsanto's new GM soybeans that make omega-3 fatty acids, and which they claim may take pressure off of already overfished species like tuna. But is it the insatiable nutritive lust for omega-3's driving the appetite for big game fish? Seems somewhat of a fishy bit of reasoning considering our growing global love for sushi, and in Japan in particular. Not only has ICCAT been criticized for a while now as supporting unsustainable fishing practices that may drive tuna to extinction.
Indeed, if you go to the world's largest fish market Tsukiji, in Tokyo, the haul is evident. They move over 4 million pounds of seafood a day, and the tuna auction is the biggest there is.
Here is a video I took this last summer of some tuna staying cool in the July heat under smal blocks of dry ice, post-auction, at a smaller retailer at the emarket:

Fat! so?

“We're kind of a popular punching bag,” said Marilyn Wann, author of “Fat! So?”
As of yesterday, a truly sweeping and historic bill overhauling the US health system narrowly passed the House of representatives (now on to the Senate).
Among all the controversy and concern over health right now and our own class discussions and readings on nutrition, obesity, and health, one important thing to consider is the generalized association of "fat" with "unhealthy."
For example, in an article this week Peggy Howell, the public relations director for the National Association to Advance Fat Acceptance, says: “We believe that fat people can eat healthy food and add movement to their lives and be healthy. And healthy should be the goal, not thin.”
As the Times article continues:
"That idea is gaining strength and popularity among a segment of the overweight population that feels as though traditional dieting to lose weight does more harm than good, ultimately benefiting the $30 billion weight loss industry, not the public"
Knowing that not only body weight itself, but susceptibility to weight related diseases is a complex interaction between environment and genetics, it is interesting to consider the categories of health that we use and their powerful, but perhaps also prejudicial and oversimplifying, extent.

Doughnut mornings in Chicago Public Schools....

Kendall Bess, right, reaches for a toaster pastry as Ameenah Saleh, left, maneuvers the breakfast line with her donut at Faraday Elementary School on the West Side. The girls. both 6, passed up the apples. (Chris Walker, Chicago Tribune / October 27, 2009)
An article in the Chicago Tribune this past week examines the food options given to Chicago Public School students, and nutritionists are a little concerned. Offering free breakfast to the students is a new policy to be lauded on many levels, but does the nutrition add up?
CPS says, hey, we are follwing USDA guidelines!
Chicago schools' food service director Louise Esaian defended the breakfasts, saying: "All of the menus served in Chicago Public Schools meet the requirements established by the (U.S. Department of Agriculture). In the majority of our schools, students are offered a choice at breakfast." She, however, did not mention that those choices include sugary pastries.
And here the ecology of information, consumer choice, and semantics rolls right in:
In fact, Chicago parents could be forgiven for not knowing doughnuts are ever served in school. That's because the word doughnut never appears on any city school breakfast menu the Tribune examined. Instead, the menus say MVP Breakfast, the product's brand name. City school officials did not respond to questions about why they use such an unrecognizable term on the menu.
But Kimberly Schwabenbauer, dietitian and marketing manager for the manufacturer, Pittsburgh-based Super Bakery, made it clear that she doesn't like to use the d-word when referring to her company's product: a round, sweet, cakey pastry with a hole in the middle. When she absolutely had to say "doughnut," she prefaced it with "quote unquote."
What does this say about education, much less nutritional education? The doublespeak is worrisome if we are trying to teach kids to be smart and critical thinkers, as well as healthy.

"Smart Choices" perhaps a Dumb Choice

In our ongoing conversation about food labeling the the ecology of information, consider the "Smart Choices program" of select nutritional labels that food manufacturers have designed and prominently posted on the front of many foods.
Selling the sense of nutrition? Food companies say they are trying to do their part in helping consumers eat according to USDA nutritional guidelines; critics say they are trying to play with the visual language and authority of quantitative data to make things like Fruit Loops seem healthy for you. As one NYU nutritionist put it:
"The point of this program is to make processed foods look healthy when what you want is people to eat foods that have been as minimally processed as possible"
The companion video segment sums it all up quite well.
As it turns out, six weeks after first being reported on widely, federal regulators have stepped in and shut the program down saying that such systems could mislead consumers, which indeed seems like the whole point of the scheme...

Oyster wars

Is there are middle way between the often conflicting concerns of food systems, safety, and satisfaction?
In the Gulf of Mexico a fight is brewing over their $500 million oyster industry. New guidelines for treating oysters to remove a potentially deadly bacteria are raising the hackles on many small oyster fishers, who claim the new measures are unnecessary, but also so costly that it may run them out of business.
Some 15 people die of bad oysters a year, but some see the whole thing as needless governmental intervention on food production and consumption:
Some oyster sellers say the FDA rule smacks of government meddling. The sales ban would take effect in 2011 for oysters harvested in the Gulf during warm months.
"We have one man who's 97 years old, and he comes in here every week and gets his oyster fix, no matter what month it is," said Mark DeFelice, head chef at Pascal's Manale Restaurant in New Orleans. "There comes a time when we need to be responsible. Government doesn't need to be involved in this."

of mice and men? getting hooked on J.F.

_____
When fed a diet of high-fat, high-calorie food, the "pleasure centers" in the brains of mice apparently become less sensitive, feeding into (pun intended) a feedback lop of over-eating. So says research just released on the topic.
"Not only did we find that the animals' brain reward circuits became less responsive as they continued to overeat and become obese," said senior author Paul J. Kenny, PhD, of the Scripps Research Institute in Jupiter, Fla., "but that decrease in responsiveness was similar to what our laboratory has seen previously in rats as they become addicted to cocaine or heroin. The data suggest that obesity and addiction may result from common neuroadaptations," he said.
The implication that food can act as a kind of drug (biochemically as well as metaphorically) is clear...
Seems like a lot more work would need to be done, but an interesting finding. I am wondering why in the experiment they seem to make the healthy food option "unpalatable"? Perhaps I am reading this wrong, but sems like that is the fundamental assumption that healthy good dones't taste good needs to be challanged more even in this reasearch(?)
