I don’t normally just post links to other content, but I think this article is such a smart and elegant polemic against “Culinary Luddism,” or the idea that “traditional” foodways (many of which aren’t actually traditional) are sacrosanct and modern industrialism has just ruined everything. I found myself nodding enthusiastically throughout and felt called to arms when I reached the conclusion:

What we need is an ethos that comes to terms with contemporary, industrialized food, not one that dismisses it; an ethos that opens choices for everyone, not one that closes them for many so that a few may enjoy their labor; and an ethos that does not prejudge, but decides case by case when natural is preferable to processed, fresh to preserved, old to new, slow to fast, artisanal to industrial. Such an ethos, and not a timorous Luddism, is what will impel us to create the matchless modern cuisines appropriate to our time.

YES. It is naive—at best— to believe that the world before industrial, processed food was idyllic in terms of nutrition, the distribution of agricultural and culinary labor, or the quality and variety of culinary experiences. At worst, ideas about what counts as “natural” or “real” with little basis in historical or scientific fact are used to reinforce social inequalities and make people feel either guilty or morally superior to others because of how they eat. Laudan corrects mistaken assumptions about the “halcyon days of yore” and critiques common beliefs about the inherent superiority of local, slow, artisanal, etc.

At least for now, the whole article is available for free. If you want to know why “modern, fast, processed” food isn’t such an unmitigated disaster after all, and why we may actually need mass-production, even if it’s a more considered, regulated, ethical form of mass-production, this is a good place to start:

“Authentic” Bagels: Boil, Bake, and Bluster

There are three things that distinguish bagels from other breads:

The first, perhaps obviously, is the shape. There are at least four different theories about the origin of the word “bagel,” and all of them refer to the shape (etymology notes below the recipe for fellow word geeks). However, you can’t just make a standard bread dough into rings, throw it in a hot oven, and expect it to develop the glossy crust and dense, chewy interior that most people associate with bagels.

The second difference is an issue of method: bagels are traditionally boiled before they’re baked, which causes the surface starch to gelatinize, producing their characteristic smooth, shiny crust. The same is true of pretzels, which originated in the same region and, according to Maria Balinska, who wrote a 2008 book about the history of the bagel, are probably related. She specifically calls them “cousins,” whatever that means in terms of food history. She also notes that the Polish obwarzanek—another boiled, ring-shaped bread often sprinkled with sesame or poppy seeds—is an “older and Christian relative,” so perhaps that’s the spinster aunt who devoted herself to Jesus. Google translates the Polish entry on “Obwarzanek” to “Bagel,” and this travel guide refers to them as “pretzel rings.” I’m sure different people have different ways of distinguishing between the three, but the boil-then-bake method they share probably makes them more alike than different. So, for example, some people might think pretzels have to be shaped like folded arms whereas other people accept rods or rings as “pretzels,” but either way they’re formed from ropes of dough that maximize the surface area exposed to the boiling water, just like their relatives.

The third difference is an ingredient—bagels are the only bread I know of whose recipes frequently call for malt extract. Pretzel recipes occasionally include it, but not nearly as often as bagel recipes, many of which claim that the malt extract is the key to making “authentic” bagels or achieving a truly “bagel-y” flavor.

The idealized referent of bagel authenticity is usually the “New York bagel,” rather than their Polish-Jewish ancestors. However, when I lived in New York City, I ate plenty of bagels—even at delis on the Lower East Side—that were indistinguishable from the ones available at chains like Brugger’s and Einstein’s nationwide. Perhaps that’s just further evidence of the declining standard described here (accompanying a recipe that demands malt powder):

I can't count how often expatriate New Yorkers would stop me on the street with tears in their eyes, telling me that mine were the best bagels they'd had since they left "The City," and that they were better than most in "The City" these days. The reasons are simple. I didn't cut corners and used good ingredients. I don't know why so many bakeries cut corners on making bagels these days, it's really NOT that hard!

But I think it’s more likely that the idea of the superior New York bagel is primarily the product of nostalgic fantasies and social decline narratives—it’s something that never was and tells you more about contemporary anxieties and desires than anything real in the past. The tears in those expatriates’ eyes say more about contemporary feelings of depthlessness and transience, the desire for connections to the past and a sense of community, and the myriad dissatisfactions that make people want to think everything was better in the “good old days” than what makes a bagel delicious or “authentic” to anything.

Malt Extract: the Ancient Sweetener in your Bud Light

Given how the same bakers describe malted barley extract on their ingredients page, its presence is probably one of the so-infuriatingly-cut corners they’re talking about:

We wouldn't dream of making bagels or kaiser rolls without barley malt extract, and neither should you! Barley malt extract improves the taste and texture of the breads it is used in. It goes by a number of names. barley malt extract and malt extract among them. If a malt extract doesn't specify what grain it is made from, chances are pretty good it was made from barley. Barley is a grain used mostly in brewing beer and making Scotch Whisky. IBarley makt [sic] extract adds a nice taste to breads where it is used. For our recipes, you can either liquid or dry, diastatic or non-diastatic malt extract and not worry about changing the recipe, any combination of these will work just fine. The important things to avoid are hopped malt extract which is really only useful for making beer and the malted milk powder sold in many grocery stores as a milk flavor enhancer which has too little malt in it and too much sugar.

Malt extract is basically just sugar made from grain, usually starting with barley. According to Harold McGee, it’s “among the most ancient and versatile of sweetening agents, and was the predecessor of modern-day high-tech corn syrups.” Just like corn syrup and agave nectar, malt extract is produced by breaking starches into their constituent sugars. Rather than adding enzymes or acids, malting works by simply germinating or sprouting the grain. As a grain germinates, it produces enzymes that digest the grain’s starch to fuel its growth. Those enzymes can be dried and mixed with cooked grains (usually rice, wheat, and barley), which they can also digest, producing a sweet slurry containing lots of glucose, maltose (glucose+glucose), maltotriose (glucose+glucose+glucose), and some longer glucose chains.

It’s not as sweet as sugar, but before sugar colonialism, it was one of the primary sweeteners available in Europe and Asia (the other two were honey and molasses made from sorghum). According to McGee, it was the primary sweetener in China until around 1000 CE, and is still used in China and Korea for confections and the sweet, caramelized gloss on dishes like Peking Duck. Malt extract is also still frequently used in beer brewing—a friend who does home brewing told me recently that American brewers are especially likely to use it to adjust the alcohol content of their beers midway through the brewing process. Apparently the laws regarding how closely the alcohol percentage matches what’s on the label are fairly strict and as the sugars in malt extract are highly available to yeast, it’s a good way to increase the yeast activity quickly and reliably.

This entry was nearly titled “Things That Might Not Kill You In Moderation But Certainly Won’t Make You Any Healthier Vol. I,” or “Hydrolyzed, Refined Sweeteners Masquerading as ‘Natural,’ Whole Foods,” but those seemed a little unwieldy. They do, however, capture the essence of the argument: agave is nutritionally no better than most other refined sweeteners, including high-fructose corn syrup (HFCS). If anything, it’s probably worse because it contains more fructose than table sugar or HFCS. It’s also no more or less “natural” than HFCS—it’s actually produced in a remarkably similar process that was first used on the fibrous pulp of the agave in the 1990s. While, as its proponents claim, the higher proportion of fructose has enabled people to call it a “low glycemic index sweetener,” sometimes alleged to be safer for diabetics and recommended by weight-loss programs like Weight Watchers, recent research suggests that large amounts of fructose aren’t healthy for anyone, diabetic or otherwise.

I mentioned agave nectar in passing in the HFCS post, but there’s enough conflicting information about it to merit its own post(s). A lot of the misinformation comes from agavevangelists, who can sometimes get a little sanctimonious about their avoidance of the demon HFCS and preference for “natural” sweeteners. Even this Vegfamily article that concludes “the physiological effects of all [caloric] sweeteners are similar” nonetheless claims:

Given the choice between sugar, HFCS, and agave nectar, I'll stick with organically-grown, unbleached cane sugar (evaporated cane juice) and organic raw agave nectar that are free of pesticides, herbicides, and chemical bleaching agents; not genetically engineered; and still retains some nutrients, as well as being vegan. Since HFCS is not available in organic form and is highly processed, I would never use it.

But agave nectar is just as processed as HFCS.

HFCS and Agave Nectar: One of These Things is Not Almost Exactly Like The Other

Like most starches, corn starch consists of large glucose polymers—70-80% the branched, non-water soluble amylopectin and 20-30% linear, soluble amylose. Normal or non-HFCS corn syrup, like Karo, is produced by breaking those polymers down into their constituent glucose molecules using acids, enzymes, and/or heat. For the history buffs: the acid hydrolysis of starch was first discovered because of the 1806 British blockade of the French West Indies. Napoleon I offered a cash reward for anyone who could come up with a replacement for cane sugar, and a Russian chemist named Konstantin Kirchhof found he could produce a sweet syrup from potato starch by adding sulfuric acid. The same process was first applied to corn in the mid-1860s, and gained popularity in the U.S. during the sugar shortages of WWI (source: The Oxford Encyclopedia of Food and Drink in America).

HFCS is produced by converting the glucose into fructose using an enzyme technology developed in Japan in the 1960s (detailed here). The resulting syrup, which contains up to 90% fructose, is then typically mixed with corn-based glucose syrup to produce HFCS-55 (the kind used in soft drinks, which has 55% fructose/45% glucose) or HFCS-45 (the kind used in baked goods, which has 45% fructose/55% glucose). Some people, like Cynthia commenting on Daily Candor, have suggested that the fructose and glucose in HFCS are absorbed into the bloodstream faster because they’re “free" instead of bound the way they are in the disacccharide sucrose, which is broken into glucose and fructose by the enzyme sucrase. Theoretically plausible, but apparently not true:

Sucrose is hydrolysed by brush-border sucrase into glucose and fructose.
The rate of absorption is identical, regardless of whether the sugar is presented to the mucosa as the disaccharide or the component monosaccharides (Gray & Ingelfinger, I 966, cited by H. B. McMichael in “Intestinal absorption of carbohydrates in man”).

Just like HFCS, agave nectar is produced by breaking down a plant-based polymer into its constituent sugars. In the case of agave, the relevant molecule is inulin, a fiber composed mostly of fructose units with a terminal glucose. Just like with corn and potato starch, there are different methods of hydrolyzing the sugars in inulin.  Blue Agave Nectar uses a thermic process. Madhava uses an enzyme process, just like HFCS.

Agavevangelists like to claim that agave nectar is a traditional sweetener used by native peoples, which appeals to the popular notion that the foodways of the past were generally healthier (e.g. Michael Pollan’s advice not to eat anything your great-grandmother wouldn’t recognize as food). Some, like Lynn Stephens of Shake Off the Sugar, merely note that the agave plant itself “has long been cultivated in hilly, semi-arid soils of Mexico.” That’s true, although it’s about as relevant as the long history of corn cultivation. Others claim that agave nectar itself has an ancient history. Flickr user Health Guy says of agave nectar: “It is 1-1/4 times sweeter than sugar, so you need less, and it has been consumed by ancient civilizations for over 5,000 years.”

Wrong. According to the website for Madhava Honey:

Agave nectar is a newly created sweetener, having been developed during the 1990's. Originally, the blue agave variety was used. This is the same plant used in the manufacture of tequila. During the late 90's, a shortage of blue agave resulted in huge increases in cost and a sweetener based on this plant became uneconomical. Further research was done and a method using wild agave was developed. Overcoming the language barrier between the Indians able to supply the nectar from the wild agave on their land and the Spanish speaking local manufacturer was the key that finally unlocked a supply of raw material and has led to our bringing this wonderful new product to market.

Still doing some native-washing (wild agave harvested by Indians who don’t speak Spanish—can’t you just feel the virtue?), but here’s what happens to the agave sap after harvesting, as described in the abstract of the 1998 patent issued for the production of fructose syrup from the agave plant:

A pulp of milled agave plant heads are liquified during centrifugation and a polyfructose solution is removed and then concentrated to produce a polyfructose concentrate. Small particulates are removed by centrifugation and/or filtration and colloids are removed using termic coagulation techniques to produce a partially purified polyfructose extract substantially free of suspended solids. The polyfructose extract is treated with activated charcoal and cationic and anionic resins to produce a demineralized, partially hydrolyzed polyfructose extract. This partially hydrolyzed polyfructose extract is then hydrolyzed with inulin enzymes to produce a hydrolyzed fructose extract. Concentration of the fructose extract yields a fructose syrup. (via Patentstorm)

It’s true that the corn used in HFCS is less likely than agave to be organically-grown, but you can get organic-certified corn syrup from the same manufacturer as the blue agave nectar pictured above and nutritionally, the main difference between that, the HFCS used in most processed foods, and agave nectar is the ratio of glucose: fructose. The regular corn syrup is 100% glucose, HFCS is usually 55/45 glucose/fructose, and agave nectar 56-90% fructose, depending on the plant and the process.

I’ve already talked a little about fructose vs. glucose here and here, but more coming soon in Agave-rant Part II concerning:

1) whether the fructose in agave is somehow better than, or indeed, different in any way from the fructose in HFCS

2) whether the fact that it’s sweeter than sugar makes it a lower-calorie alternative to sugar

3) whether its “low glycemic index” rating makes less likely to produce insulin resistance than table sugar and

4) whether it’s safer for diabetics

All of which people have claimed. I won’t keep you in suspense, especially given how long it may take me to put all of that together. The short answers are:

1) not in any nutritionally meaningful way

2) perhaps very slightly, but a <10 calorie/serving difference likely doesn’t make up for the increased risk of fatty liver syndrome and insulin resistance

3) no, it’s actually more likely to produce insulin resistance and

4) in miniscule amounts, perhaps, but recent trials involving diabetics and agave nectar were halted because of severe side effects.

Salt has been all over the news this week because of a study just published in The New England Journal of Medicine claiming that if everyone in the U.S. reduced their sodium consumption by 3 grams/day, there would be 32,000 fewer strokes, 54,000 fewer heart attacks, and 44,000 fewer deaths every year. The story that got my attention was:

That’s surprising, I thought. Everything I’ve read suggests that the relationship between salt consumption and cardiovascular disease is weak, inconsistent, and probably only valid for 20-30% of the population. So I expected the article to refer to some new research where, you know, “big benefits” were “seen.” As in observed. Like, in the world. And, given the claim about the magnitude, probably also measured.

To their credit, the authors of the study claim no such thing. The numbers are projections based on the application of several assumed effects of salt reduction, adjusted for different demographics and then applied to a model of the entire U.S. population. Thus, the title of the study: “Projected Effect of Dietary Salt Reductions on Future Cardiovascular Disease.”

The article seems to grasp the essentially speculative nature of the findings. The very first sentence uses the conditional tense:

…scientists writing in The New England Journal of Medicine conclude that lowering the amount of salt people eat by even a small amount could reduce cases of heart disease, stroke and heart attacks as much as reductions in smoking, obesity, and cholesterol levels.

The headline, on the other hand, seems to have confused the “scientists” with clairvoyants. Never mind doing any checking into the validity of their assumptions.

And the claim about how the benefits compare to smoking and obesity reduction led to a few headlines like this:

This crazypants idea initially sounds a lot like what the study’s lead author claims:

"The cardiovascular benefits of reduced salt intake are on par with the benefits of population-wide reductions in tobacco use, obesity, and cholesterol levels."

But the logic behind the claim is that a small improvement in the health of every single American would be as significant as a large health improvement in the health of every single smoker:

Dr. Bibbins-Domingo said that for many people the decrease in blood pressure would be modest, which is why, she said, “many physicians have thrown up their hands and said, ‘I’m not going to advise my patients to reduce salt because it’s too hard for patients and the benefits for any individual are small.’

“But small incremental changes in salt, such as lowering salt in tomato sauce or breads and cereals by a small amount, would achieve small changes in blood pressure that would have a measurable effect across the whole population,” she said. “That’s the reason why this intervention works better than just targeting smokers.”

For any given individual, there is no question about whether cutting salt is even close to “as good” as quitting smoking. The evidence for the link between smoking and lung cancer and death is strong, reliable, consistent, and has a clear causal mechanism (carcinogens). The link between salt and cardiovascular disease and death is weak, inconsistent, and still poorly understood.

That latter point starts to get at the problems with the study itself, and not just the headlines it inspired. A number of the assumptions the projection was based on are either demonstrably false or simply unsubstantiated. More on this some other time; for now, a few quotes and links to the essays they come from in Esquire and the medical journal Hypertension:

In a more recent statement, the founder of the American Society of Hypertension, Dr. John Laragh, goes further: "Is there any proven reason for us to grossly modify our salt intake or systematically avoid table salt? Generally speaking the answer is either a resounding no, or at that, at best, there is not any positive direct evidence to support such recommendations."

…

Studies show that 30 percent of the Americans who have high blood pressure would greatly benefit from a low-sodium diet. But that's about 10 percent of the overall population -- the rest of us are fine with sodium. And drastically cutting out sodium may actually hurt some people. ( "Go Ahead, Salt Your Food")

And:

The available data suggest that the association of sodium intake to health outcomes reflected in morbidity and mortality rates is modest and inconsistent. Therefore, on the basis of the existing evidence, it seems highly unlikely that any single dietary sodium intake will be appropriate or desirable for each member of an entire population.... The decision to adopt a low sodium diet should be made with awareness that there is no evidence that this approach to blood pressure reduction is either safe, in terms of ultimate health impact, or that it is as effective in producing cardioprotection as has been proven for some drug therapies.
