"If People Could See How Their Food Is Produced, They Would Change How They Eat" - Michael Pollan

2009-12-05T08:16:00.003-05:00

Here's a gem of an article, tucked away in the unlikely, biotechnology-friendly website Truth About Trade & Technology. It's a recent interview with Michael Pollan, where he says...

"I visited an industrialized potato farm in Idaho and saw how freely pesticides were used. The farmers had little patches of potatoes by their houses that were organic. They couldn't eat their field potatoes out of the ground because they had so many systemic pesticides. They had to be stored for six months to off-gas the toxins."

"An "organic feedlot" should be a contradiction in terms, but it's not under the rules."

Cabbage Soup

2009-12-03T06:53:00.003-05:00

Actually Brussels Sprouts Soup (BS Soup), but I use cabbage when BS aren't available. (Are BS an acquired taste?) I eat this, or some permutation of this often when the days get cold. It comes together quickly if you have leftovers. Serves 1.

3 or 4 Brussels sprouts (or cabbage)
1/4 cup diced sweet onion (Vadalia or Mayan)
1/4 cup diced leek (dark and light green mixed)
2 large mushrooms, diced (white or crimini)
1/4 cup cooked white beans (navy, great northern, or cannellini)
1/4 cup chopped, cooked (or frozen & thawed) greens (spinach, kale, or other dark green)
1 teaspoon tamari (or to taste)
1/2 teaspoon gomasio
salt to taste
pepper to taste

Clean and cube Brussels sprouts; smaller cook faster. Boil in about 2 cups water for 15-20 minutes. Add onion, leek, and mushrooms. Turn heat down and simmer for 5 minutes. Add beans and simmer another 5 minutes. Add cooked dark greens at the end and simmer for just another minute. Season with tamari and gomasio. Let sit for a few minutes so flavors blend and soup sets.

This is just vegetable soup. Any vegetables work. Just put harder root vegetables like carrots in first so they cook longer than softer ingredients like zucchini or onions.

I don't use fat. If you have time, desire, and the patience to clean another pan, you can sauté the vegetables first.

There are usually some cooked beans in my fridge. (I just soak any dry bean overnight, boil them for a few hours as soon as I get up, and store them in the fridge.) Since I make them from scratch, they have a nice thick sauce you don't get from canned beans. It gives the soup a creamy consistency without added fat.

Barry's Back!

2009-12-02T10:29:00.003-05:00

I'm glad Barry Estabrook is back. Estabrook wrote the "Politics of the Plate" column for Gourmet magazine - before the magazine closed last month. He's back now with his own blog: Politics of the Plate.

His latest entry talks about sludge.

San Francisco's Public Utility Commission is offering free compost to anyone who wants it - "high-quality, nutrient-rich, organic biosolids compost." Good stuff. But Barry writes:

"What the Public Utilities Commission fails to disclose, the Center for Food Safety (CFS) says, is that the popular soil amendment is made out of sewage sludge composted with wood chips or paper by-products.

According to a report released this year by the Environmental Protection Agency (EPA), sludge has been found to contain heavy metals, pharmaceuticals, PCBs, flame retardants, and endocrine disruptors -- pretty much anything that humans living and working in a large metropolitan area flush down their toilets or pour down their drains. The CFS claims that San Francisco’s compost contains “toxic chemicals and hazardous materials."

So hazardous that...

"A federal judge ruled in favor of farmers who sued the USDA when their cows became ill and died after eating silage grown on land upon which sludge had been applied."
- Barry Estabrook's Politics of the Plate, Sludge Fest: Center For Food Safety Vs. San Francisco. It’s A Battle That May Be Coming Soon To A City Near You

________
If human waste disposal isn't enough of a problem, Foer writes that the amount of excrement generated on industrial livestock farms is about to surpass that produced by the entire human population. And...

"There is almost no waste-treatment infrastructure for farmed animals -- no toilets, obviously, but also no sewage pipes, no one is hauling it away for treatment, and [there are] almost no federal guidelines regulating what happens to it."

What does, say, America's leading pork producer, Smithfield, do with all that excrement?

"When the football field-sized cesspools are approaching overflowing, Smithfield, like others in the industry spray the liquefied manure onto fields. Or sometimes they simply spray it straight up into the air, a geyser of shit wafting fine fecal mists that create swirling gases capable of causing severe neurological damage."

Homemade Yeast - Update

2009-12-02T08:45:00.004-05:00

This was about 2 days later (than this). There's some real leavening power now! As well as some alcohol.

I had another jar going (these are re-used jelly jars) but it formed a hairy mold on top. I fed that back to our municipal water. I don't want to rinse the raisins since I feel I may wash away yeast. But it looks like there are other things growing on raisins that I don't know about.

The raisins that formed mold were Newman's Own Organic. The raisins that gave good yeast growth were Trader Joe's Organic Thompson.

Is Eating Personal? The Divide

2009-11-30T07:54:00.009-05:00

Lots of talk about this so I thought I'd post a poll. See Sidebar.

Here are opinions I've collected so far:

Yes. Eating is personal. It's my business:

Al Gore (Former Vice President) in answer to: Have you become vegetarian? "No, I have not. ... I don't plan to. I respect those who do. But it's a personal choice and will remain so."
Jonathan Safran Foer (Author "Eating Animals"): "My decision not to eat animals is necessary for me, but it is also limited -- and personal."
Nicolette Niman (Manages Niman's livestock ranch): "I feel I can personally make a choice to refrain from consuming meat for my own individual reasons."

No. Eating is not personal. It's everyone's business:

James McWilliams (Author "Just Food"): "It's hard to avoid concluding that eating cannot be personal. What I eat influences you. What you eat influences me."
Bruce Friedrich (PETA): "The influence our eating choices have on others [is important]. ... The public aspects of eating are critical."
Wendell Berry (Writer): "Eating is an agricultural act."
Michael Pollan (Author "Omnivore's Dilemma"): "Eating is a political act."
Alice Waters (Restaurateur): "Eating is a political act."

Homemade Yeast

2009-11-29T10:46:00.007-05:00

Here's my homemade GMO-free yeast. I'm making it from soaking raisins. The bubbles adhering to the sides of the grapes are, I hope, carbon dioxide gas given off by yeast as they feed on carbohydrates. (Click to enlarge.)

I'd expected something frothier but it's still young, just 2 days. And it's cold here in Philly (in the 20s outside/60s inside at night). I'm not sure how successful this will be yet. I'll give it time.

I'm planning on using this with another experiment of mine: Sprouted Wheat Bread.

Sprouted Wheat Bread - Technology Demonstrator

2009-11-26T12:39:00.005-05:00

(This is Part 2 in my effort to make sprouted wheat bread. See my previous post for sprouting the wheat.)

Nowhere did anyone say anything about the grinding part. This isn't funny.

The food processor was fruitless. The wheat kernels remained virtually intact, stuck to the sides of the workbowl, save for their little hairy stems that collected in a gooey mash on top. One appliance into the sink.

The blender did a better job, but only in batches of about 1 cup. It took about 2 to 3 minutes of blending per cup, lowest speed, with lots of stops to wipe down the sides. The motor heated up, as did the dough. This was advantageous since the wheat was still cold from the refrigerator and it will rise better warmed.

Here's what it looked like after a few pulses in the blender. A lot better than the food processor, but still not gloppy enough (I don't think):

Here's what I went with. This is just wheat, no other ingredients, not even water:

The clean up. Not funny.

Sprouted Wheat

2009-11-25T13:22:00.003-05:00

For sprouted wheat bread (flourless). A first.

The wheat on the right has been sprouting for 42 hours. (On the left is what I started with - a hard winter wheat.) I think it's ready but I'm not. I'll put it in the fridge to slow growth until tomorrow. I hope it still works.

How To Sprout

Soak - Rinse wheat. Place into a bowl. Cover with tepid water and let soak, at room temperature, for 8 to 12 hours.

Sprout - Drain soaked wheat, rinse, and strain. Cover bowl with a damp towel. Store in a dark place at room temperature. Rinse thoroughly (immerse in tepid water first) every 12 hours, for between 36 and 48 hours, depending on how warm your room is. Keep the towel damp.

Jonathan Foer's book is hard to read.

Here's a story. It begins a chapter where he discusses the acts involved in transforming a living animal into a processed animal.

"Paradise Locker Meats used to be located somewhat closer to Smithville Lake, in northwestern Missouri. The original plant burned down in 2002 when a fire broke out as a result of a ham smoking gone awry. In the new facility is a painting of the old plant, with the image of a cow running from the back. This is a depiction of an actual event.

Four years before the fire, in the summer of '98, a cow escaped the slaughterhouse. She ran for miles -- which, if the story had ended there would have been remarkable enough to justify its telling. But this was some cow. She managed to cross roads, trample or otherwise disregard fences, and elude the farmers who were searching for her.

And when she came to Smithville's shore, she didn't test the water, think twice, or look back. She attempted to swim to safety -- the second leg of her triathlon -- wherever that might be. At the very least, she seemed to know what she was swimming from. Mario Fantasma -- the owner of Paradise Locker Meats -- received a phone call from a friend who saw the cow take the dive. The getaway finally ended when Mario caught up with her on the other side of the lake. Boom, boom, curtain. Whether this is a comedy or a tragedy depends on who you think the hero is."

Folic Acid Supplements May Increase Cancer Risk

2009-11-19T11:56:00.008-05:00

This post is going to say much the same as my post about omega-3 fatty acids (fish oil) and cancer. In fact, I'll just recycle the last sentence of that post:

"Like most nutrients, there appears to be an ideal range for ~~omega-3 fatty acids~~ folate in the body, above and below which an individual can experience poor health."

A new study in JAMA this week is reporting an increased cancer risk among those who took folic acid supplements:
Cancer Incidence and Mortality After Treatment With Folic Acid and Vitamin B12, Journal of the American Medical Association, November 2009

The risk was not high (21% increased risk for getting cancer, 38% increased risk of dying from cancer) but it was statistically significant. Lung cancers led the pack.

Patients who experienced increased risk were taking 800 micrograms/day (mcg/d) of folic acid.¹ (They also took 400 mcg/d of vitamin B12 and/or 40 mg/d of vitamin B6. But those were found not to affect cancer rates.)

The recommended allowance (or DRI: Dietary Reference Intake) for folic acid in this country is 400 mcg/d. So they were taking twice the DRI. Yet they fell short of the tolerable upper intake of 1000 mcg/d.

In our body, folate is used in DNA replication - it's needed for cell growth and repair. Cancer cells also use it for growth.

Two items of note:

Participants in this combined analysis lived in Norway where there is no fortification of foods with folic acid. The US embarked on a mandatory fortification program in 1998 - flour and grain products here contain added folic acid. That's in addition to the folic acid added to our breakfast cereals, often 400 mcg/serving. (A bowl of cereal and a typical vitamin pill can easily put you at 800 mcg. Eat anything made with folic-acid-fortified-flour and you'll surpass their intake.)
One mechanism put forth for the increased cancer rates was reduced activity of our immune system's natural killer cells in the presence of high levels of folic acid.² Coincidentally, high intakes of omega-3 (about 1 gram/day) were also seen to reduce the amount and activity of natural killer cells.

Vitamin pill popping is not as innocent as supplement manufacturers make it out to be.
________¹ Folate found naturally in food hasn't been shown to be harmful. Green leafy vegs are a great source - about 270 mcg folate in 1 cup cooked spinach.

Is Eating Personal?

2009-11-17T07:37:00.008-05:00

I want to contrast these words from Al Gore who spoke to Jeremy Paxman last week on BBC's Newsnight program ...

Paxman: "Have you become a vegetarian?"
Gore: "No, I have not. ... I don't plan to. I respect those who do. But it's a personal choice and will remain so."

... with these words from James McWilliams, author of the recent "Just Food," writing in The Washington Post yesterday:¹

First he set the scene:

"I gave a talk in South Texas recently on the environmental virtues of a vegetarian diet. As you might imagine, the reception was chilly. In fact, the only applause came during the Q&A period when a member of the audience said that my lecture made him want to go out and eat even more meat. "Plus," he added, "what I eat is my business -- it's personal."

Then argues the opposite of Gore:

"It's hard to avoid concluding that eating cannot be personal. What I eat influences you. What you eat influences me."

And gives these statistics to argue his claim:

The livestock industry -- as a result of its reliance on corn and soy-based feed -- accounts for over half the synthetic fertilizer used in the US, contributing more than any other sector to marine dead zones.
Livestock consume 70% of the water in the American West -- water so heavily subsidized that if irrigation supports were removed, ground beef would cost $35 a pound.
Livestock accounts for at least 21% of greenhouse-gas emissions globally -- more than all forms of transportation combined.
Domestic animals -- most of them healthy -- consume about 70% of all the antibiotics produced. Undigested antibiotics leach from manure into freshwater systems and impair the sex organs of fish.
If all the grain fed to animals went to people, you could feed China and India.

He also addressed animal welfare, including the ludicrousness of the term "free-range," the crass disposal of "economically worthless" male chicks, the cutting-off of body parts from live animals without anesthesia, and others.

He wraps it up:

"Now, if someone told you that a particular corporation was trashing the air, water and soil; causing more global warming than the transportation industry; consuming massive amounts of fossil fuel; unleashing the cruelest sort of suffering on innocent and sentient beings; failing to recycle its waste; and clogging our arteries in the process, how would you react? Would you say, "Hey, that's personal?" Probably not. It's more likely that you'd frame the matter as a dire political issue in need of a dire political response.

Vegetarianism is not only the most powerful political response we can make to industrialized food. It's a necessary prerequisite to reforming it."

Lots to chew on.

One last point. He said this about some popular alternatives:

"We've been inundated with ideas: eat local, vote with your fork, buy organic, support fair trade, etc. But these proposals all lack something that every successful environmental movement has always placed at its core: genuine sacrifice."

It's true.

Irradiation Of Cat Food Causes Paralysis

2009-11-15T08:18:00.010-05:00

Well, this is interesting...

Cats fed dry cat food that had been irradiated (Orijen brand from Champion Petfoods Ltd of Canada) suffered forms of paralysis and subsequent death. Many were euthanized.¹

It does appear that irradiation of the food caused the illness:

"Previously published data and strong circumstantial evidence in this outbreak suggest that single-dose gamma irradiation of dry pet food at high levels (>36.3 kGy) is associated with the development of leucoencephalopathy in cats. We suggest that food irradiated at high levels should not be fed to cats as it poses a significant risk of severe neurological disease.

Orijen was subject to a total gamma irradiation dose >50 kGy on entry to Australia."

How consumption of irradiated food may cause neurological damage:

"Irradiation results in the production of ions and free radicals, including high-energy oxygen radicals, that are used to kill or damage pathogenic organisms in food. Irradiation doses of foods for human consumption normally range from less than 1 up to 10 kGy. Larger doses (30 kGy) have been approved for dried herbs, spices and dehydrated vegetables. Oxygen radicals produced by irradiation will also cause the formation of lipid oxides by directly reacting with membrane lipids and other lipids in foods, and some foods such as fatty fish and meat are not considered good candidates for irradiation. Irradiation also induces chemical changes in carbohydrates and proteins by the action of hydroxyl radicals and hydrated electrons generated from water molecules to produce radiolytic products. These products are also generated in cooking or pasteurisation."

So, the dose of radiation was thought to be significant in this case, but the risk from chronic, low-dose exposure wasn't ruled out:

"However, the mechanism by which changes induced in foods then result in damage to the white matter of the spinal cord and brain is not clear. Whether a single insult to the CNS results in on-going damage or whether the damage is the result of cumulative or repeated insult remains speculative."

Maybe this is something just unique to cats? I know the USDA/FSIS is considering (and the American Meat Institute is endorsing) the use of radiation on beef to reduce risk from foodborne pathogens. Some ground beef on the market is already irradiated.

I wonder what happened to all that recalled cat and dog food, in so much as "the fate of salvaged pet food ... it gets turned into feed for pigs, poultry, and farmed fish," according to Marion Nestle.

Jonathan Safran Foer Defines "Free-Range"

2009-11-14T15:08:00.004-05:00

Fighting words from Jonathan Safran Foer:¹

Free-Range:

"Applied to meat, eggs, dairy, and every now and then even fish (tuna on the range?), the free-range label is bullshit. It should provide no more peace of mind than "all-natural," "fresh," or "magical."

(Imagine a shed containing thirty thousand chickens, with a small door at one end that opens to a five-by-five dirt patch -- and the door is closed all but occasionally.)

Very often, the eggs of factory-farmed chickens -- chickens packed against one another in vast barren barns -- are labeled free-range.

One can reliably assume that most "free-range" (or "cage-free") laying hens are debeaked, drugged, and cruelly slaughtered once "spent."

I could keep a flock of hens under my sink and call them free-range."

Banana Squash

2009-11-13T07:43:00.015-05:00

It resembles a banana, a big banana, except when it's green:

I'd been wanting to try one but most I'd seen, if I saw any, were 2 feet or longer. Too unwieldy. And since I bake it whole, not oven-friendly. When I spotted this one, a little under 2ft., I snatched it.

Into a 310ºF oven for about 1.5 hours, or until soft.

The slightly warm and moist squash was heavy and handled, with all due respect to aquatic animals, like a dead fish. (I bake it whole to avoid the life-in-your-hands task of cutting raw squash rind. You could use a butter knife to slice this open and a teaspoon to scoop seeds.)

All that work ... for around 1.13 cups of squash meat.

The taste and texture? More on the savory side, that is, not very sweet. And very wet. It's unlike the drier and sweeter kabocha or buttercup (not butternut) squashes. I'll probably make a soup with this, something like:

Apple Squash Soup

1 or 2 cups cooked squash (Butternut squash makes a good substitute.)
1 or 2 cups sautéed apples (Here's a very old post on making sautéed apples.)
1 cup apple cider or juice
Dash cinnamon
Dash nutmeg
Dash salt
Few squeezes lemon juice

Purée squash and apples in a food processor or blender. If necessary, add some apple cider to help purée. Reserve a few nicely browned apples for garnish.

Transfer purée to a soup pot. Thin with cider to desired consistency. Season with spices, salt, lemon juice or as desired. Heat.

Garnish with dried cranberries or dried cherries, toasted almond slivers or walnut pieces, and reserved apples slices. A swirl of cranberry sauce looks nice too.

The Uniqueness Of Humans

2009-11-11T14:25:00.006-05:00

Stanford professor of neurology, Dr. Robert Sopolsky, spoke to Stanford's 2009 graduating class about the uniqueness, and the not-so-uniqueness, of humans. Topics included aggression, theory of mind, the golden rule (tit-for-tat), and pleasure. His speech begins at 4:55 minutes:

An excerpt:

"You have two humans, and they are taking part in some human ritual. They are sitting there silently at a table. They make no eye contact; they’re still, except every now and then one of them does nothing more taxing than lifting an arm and pushing a little piece of wood. And if it’s the right wood and the right chess grand masters in the middle of a tournament, they are going through 6,000 to 7,000 calories a day thinking, turning on a massive physiological stress response simply with thought and doing the same thing with their bodies as if they were some baboon who has just ripped open the stomach of their worst rival, and it’s all with thought, and memories and emotions. And suddenly we’re in the realm of taking just plain old nuts and bolts physiology and using it in ways that are unrecognizable."

Olive Oil Vs. Walnuts: Guess Which Won

2009-11-09T08:20:00.004-05:00

This is one of the studies from my previous post about walnuts:

A Walnut Diet Improves Endothelial Function In Hypercholesterolemic Subjects, Circulation, 2004

It compared two diets. Both were a Mediterranean diet - emphasizing vegetables and fish, and limiting red and processed meats, whole-fat dairy foods, and eggs. There was one difference: one diet replaced some olive oil and other sources of monounsaturated fat (olives, avocados) with walnuts.

The walnut diet was better:

"Compared with the Mediterranean diet, the walnut diet improved endothelium-dependent vasodilation and reduced levels of vascular cell adhesion molecule."

"Compared with the Mediterranean diet, the walnut diet produced significant reductions in total cholesterol and LDL cholesterol."

The benefit of walnuts may go beyond (or act synergistically to) its fatty acid profile. For example, walnuts contain good amounts of the amino acid L-arginine, certainly compared to almost-all-fat olive oil, and L-arginine can lower blood pressure, that is...

L-arginine is used to make nitric oxide, a compound that helps dilate blood vessels, lowering blood pressure. (L-arginine is good for erectile dysfunction too, for the same blood-vessel-dilating reason). An aside - dark chocolate also increases nitric oxide, and may be partly responsible for its heart benefits.

Just one study.

What Do People Opposed to Factory Farming Feed Their Pets?

2009-11-02T10:11:00.006-05:00

As I'm reading Jonathan Safran Foer's various essays¹ which question the practice of factory farming, I'm wondering what he feeds his dog. What do people who oppose Concentrated Animal Feeding Operations (CAFOs) feed their pets? Or do they opt out of pet ownership?

Marion Nestle, in her book Pet Food Politics, says:

"Pet foods have always been made from the leftover parts of slaughtered farm animals that are not going to be used for human food—the bones, organs, ears, and other nutritious by-products. The need for an outlet for the leftovers of animal slaughter is one of the reasons commercial pet food exists."

Where do those animals that get made into dog and cat food come from? Foer says:

"Upwards of 99 percent of the animals that are raised for meat in this country come from factory farms."

Bats Quenching Their Thirst

Some rare photos of bats swooping down over a pond at night to drink. (Click to enlarge.)

"Travelling at 20mph, with wing beats not visible to the human eye and flying mostly at night the bats are notoriously difficult to photograph."

"They are so detailed you can even see the night creatures slurping from the pool with their little pink tongues."

Those tongues.

Photos were taken by Kim Taylor of Surrey, England. Here's Kim and his home-made set-up:

He suspended ropes to direct bats to a narrow swooping zone, used an infrared beam that triggered flash bulbs when a bat broke it, and attached a device to his camera that listened for ultrasonic squeaks which opened the shutter.

I love seeing this kind of devotion to a project.

Can Omega-3 Fatty Acids (Fish Oil) Predispose Someone To Cancer?

2009-10-30T08:34:00.005-04:00

Or to viral infection?

Omega-3 (n-3) fatty acids, which include longer-chain EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) and shorter-chain ALA (alpha-linolenic acid), have been shown to reduce inflammation and are beneficial for inflammatory conditions - those involving joints (rheumatoid arthritis), bowels (colitis, Crohn's), lungs (asthma, COPD), arteries (atherosclerosis), skin (psoriasis), and others.

Inflammation is thought to decrease via a change in activity or production of cells involved in the immune response. Our immune response is integral in keeping cancer (and infection) at bay.
________
This study...
Leukocyte Numbers And Function In Subjects Eating N-3 Enriched Foods: Selective Depression Of Natural Killer Cell Levels, Arthritis Research and Therapy, 2008

... found that:

"Natural killer (NK) cell numbers were lower in n-3 supplemented subjects* than in controls, and were inversely related to the amount of EPA or DHA in erythrocytes."

So, the more omega-3 detected in red blood cells, the fewer natural killer cells the subjects had, and:

"NK cells are important in immune surveillance, particularly against viral infections and cancer. ... Individuals consuming these fatty acids may have greater susceptibility to viral infections. NK cells provide a first-line defense against these pathogens."

This study elucidated a type of n-3 that may be more immuno-suppressive:
Dietary Supplementation With Eicosapentaenoic Acid, But Not With Other Long-Chain N-3 Or N-6 Polyunsaturated Fatty Acids, Decreases Natural Killer Cell Activity In Healthy Subjects Aged >55 Y, American Journal of Clinical Nutrition, 2001

"Fish oil* caused a significant reduction (mean decline: 48%) in NK cell activity that was fully reversed by 4 wk after supplementation had ceased.

Thus, it might be inappropriate for groups at risk of viral infection and some cancers to increase their intake of EPA."

* Subjects consumed 1 gram EPA plus DHA a day. (720 mg EPA + 280 mg DHA)
________
Other studies have shown that fish consumption or fish oil supplementation can be protective against cancer. It appears some antioxidant, like vitamin E, also needs be present - probably because it prevents oxidation of the easily-oxidized polyunsaturated omega-3 fats.

There is thinking that fish oil, and some forms of oil-based vitamin D, can be harmful to the liver.¹ Anecdotally - some people experienced elevated liver enzymes while taking fish oil only to have them fall back into the normal range when they stopped. More study needed there.

Like most nutrients, there appears to be an ideal range for n-3 fatty acids in the body, or better, an ideal ratio of omega-6:omega-3, above and below which an individual can experience poor health.

Reading Books

2009-10-29T07:55:00.007-04:00

Dr. Andrew Weil posted his review of Jonathan Safran Foer's new book, "Eating Animals" yesterday:

The Moral Ferocity of Eating Animals

The topic is polarizing, but it was this part of Weil's review that stood out for me:

"In the Internet age, as our attention is diced into ever-tinier blog posts, blurbs, bleats and tweets, some have speculated that books are obsolete. Millions are satisfied with non sequitur eruptions. What good are works that span 300 pages? One answer is that adopting a truly life-changing idea -- like radically changing one's eating habits -- takes time and persuading."

"Millions are satisfied with non sequitur eruptions." ... Is curiosity on the wane?

Doughnut Cheeseburger

Seinberg sent this:

Craz-E Burger: Americans Embrace 1,500 Calorie Doughnut Burger

"Consisting of a bacon cheeseburger with a buttered, grilled and glazed doughnut standing in for a bun ... Its 1,500 calories of sugar and saturated fat did not stop it from becoming a huge hit at a major fair in Massachusetts ... Visitors bought around 1,000 Craz-E burgers each day of the fair's 17-day run."

17,000 of these consumed in 17 days, at one fair. That's one popular sandwich.

What impressed me, besides the outrageousness of it, was the promotion of it: "The perfect rejoinder to the healthy eating lobby." Do people make food choices out of some kind of rebellion?

My friend's take on this:

"It is appealing to the defiance of teenagers to authority. Unfortunately we live in a country where adolescence is nurtured by the media since adolescents are easy to manipulate. So 40 year olds never learn to grow up and become adults and take care of themselves."

He has a point.

Found Food

This was unexpected. I don't have a garden, but I do keep herbs on the porch. One day this summer, I squeezed some old potatoes into the soil between the parsley and chives. Never grew potatoes in my life. Don't know what a potato plant looks like - although I do now. I was concerned the monster vines would crowd out the coriander, but I let them go. They grew fast, had small pink flowers (that some insect or worm snipped off at night), and died a few weeks ago in the near-frost. This is what they left behind.

Does Cheerios Lower Cholesterol?

2009-10-26T07:58:00.004-04:00

Cheerios upped the ante this summer by advancing their "lowers cholesterol 4% in 6 weeks" claim to "lowers cholesterol 10% in one month."

The abstract for the study upon which this new claim is being made is:
Ready-to-eat Oat Cereal, as Part of a Reduced Energy Diet, Reduces Low-density Lipoprotein Cholesterol and Waist Circumference in Overweight and Obese Adults, FASEB.

The study is still unpublished. Results were presented in April of this year at the Experimental Biology Meeting in New Orleans.

Of note:

The abstract shows 8.7% reduction, not 10% reduction.
The 8.7% reduction was for LDL cholesterol.
The 8.7% reduction was achieved not only by eating 3 cups of Cheerios a day, but by reducing calories (by ~500 calories/day) and by reducing fat intake.
The control group (which did not eat Cheerios but ate the reduced calorie, low-fat diet) also experienced lower LDL cholesterol (4.3%) and lower total cholesterol (2.9%).
The 8.7% reduction is, in fact, a 4.4% reduction when compared to control group.
There was no difference between groups in weight loss, HDL cholesterol, or triglycerides.

The following point makes me question the researchers' motives:

The control group didn't just not eat the Cheerios, but it consumed "low-fiber control foods." It would be interesting to see the fiber types and intakes of both groups, before and during the intervention. How much was the control group's fiber intake suppressed? (For the sake of a positive result?)

The reduction in cholesterol did not occur outside of the context of a reduced-calorie, reduced-fat diet. The FDA sent General Mills a warning letter in May, less than 3 weeks after the results of the above study were presented, addressing this point:

"[Your claim] leaves out any reference to fruits and vegetables, to fiber content, and to keeping the levels of saturated fat and cholesterol in the diet low. Therefore, your claim does not convey that all these factors together help to reduce the risk of heart disease and does not enable the public to understand the significance of the claim in the context of the total daily diet."
- FDA Warning Letter to General Mills, Inc. 5/5/09

"[Cheerios] is not generally recognized as safe and effective for use in preventing or treating hypercholesterolemia or coronary heart disease. Therefore, under section 505(a) of the Act [21 U.S.C. § 355(a)], it may not be legally marketed with the above claims in the United States."
- FDA Warning Letter to General Mills, Inc. 5/5/09

One conclusion you might draw from this study is that relative to a low-fiber diet (we don't know how low), Cheerios may reduce LDL cholesterol by ~4%. That's like saying you're going to study thirst; you withhold fluid from the control group, feed Coke to the intervention group, and find that Coke prevents thirst.

Not only was this study funded by General Mills, it was designed by their researchers - who knew exactly what they were doing when they set the parameters.
