Salt of the Earth, and the Ocean

Is any other natural substance so encrusted by myth and practical observations? The number of informal borrowings of the word to imply humanly recognized concepts is staggering. For example,

“To capture unwary investors, they salted the mine.”
“She salted away most of her fortune.”
“He’s not worth his salt.”

Salt is fundamentally sweat, whether generated by brutal forced labor or pleasant voluntary exercise. Everyone has heard salt used as a figure of speech. (A-Z Quotes offers close to 700 sayings by the famous and the obscure.)

All over the world, in many times and places, salt has been an international currency accepted with no questions asked. Despite being an eminently pragmatic commodity, it has been valued like gold or jewels. Even in an era like this one, when salt seems common as dirt and is given away for free in little paper packages, it is universally recognized as having value.

How naughty is it?

On the topic of unwise food choices, the role of salt as accomplice and enabler is paralleled by no other substance. Consider the delightful movie-theater snack combo of salted popcorn and chilled cola drink, so loved, yet only available during recent history. This culinary masterpiece packs such an extraordinary one-two punch that the people who lived before its time can only be pitied.

Salt is probably the single greatest cause for the rise of the soda industry. The unique experience of switching from salty to cold-fizzy-sweet, and then back to the salted potato chips (or salted any sort of chips), and then to the chilled beverage, on and on, interminably… ad infinitum… Is any sensation more heavenly? The poignant contrast can bewitch a person for hours.

Just a side note, but the second-largest accomplice to the insidious rise of cola drinks has to be the refrigerated vending machine. The genius who figured out how to keep bottled beverages cold until some poor sucker came along and dropped a quarter into the slot may be responsible for just as much obesity as salt itself.

A slice of history

Many of us who are middle-aged and beyond grew up very familiar with the experience of sitting at a table where each adult thoughtlessly grabbed a salt shaker and automatically covered everything on their plate with salt, barely pausing to glance, and knowing exactly how much of it should be distributed per square inch of food surface. In every case, it was too much.

Today, a sane person, if one can be found, draws the line at about a level teaspoon (about six grams) of salt per day. But, considering how much sodium is already injected into packaged food items, even that is probably excessive. And, 2,000 mg of salt per day is about the outer limit a conscientious adult should go with.

It was tempting to include here a compendium of examples from this very website, to prove the overwhelming presence of salt in the human diet and consciousness. One alternative would have been a comprehensive list of each Childhood Obesity News post that has thus far mentioned the word “salt,” totaling at least 360 of them. This would be somewhere close to the neighborhood of one out of every 10 posts ever created for this venue.

The likelihood that any American suffers from insufficient sodium intake is vanishingly small.
Okay, someone who sweats a lot may be an exception to that broad generalization. These include competitive athletes and workers exposed to major heat stress, such as foundry workers and firefighters.

But for pretty much everybody else, on the scale of Things to Worry About, a sodium deficiency is way down the list, registering less than a whisper of a dream. This same American Heart Association information source, by the way, warns that sodium can be sneaky, and offers a printable version of its one-page infographic, “7 Salty Myths Busted.”

Additionally, and especially appreciated here at Childhood Obesity News, is a printable poster geared for kids, explaining the myths and the facts of sodium.

P.S. A note: While no doubt full of many virtuous qualities, green salt does not taste salty. Sorry, it just doesn’t.

It’s Sodi-licious

A recent post observed that, rather than decreasing, the amounts of fat, sodium, and sugar in manufactured breakfast cereals have only continued to increase. Over the past decade, journalists in the health field have unrelentingly noted that such products — especially those aimed at children — inevitably include more and more sugar, sodium, and fat. It is almost as if attentive reporting on the topic has perversely led the situation to become even worse.

Plenty of information appears printed on food packaging, and an abundance of articles about the contents of those packages are published through various media. Regarding the boxes, cans, bottles, and other food packages, along with the journalism about what is inside them, why don’t all these information sources just go ahead and say, “Salt”? Is someone just showing off with fancy words, or what? Sodium and salt, aren’t they the same?

As it turns out…

After consulting Sharon Small, a dietitian who specializes in counseling patients about their cardiovascular health, journalist Wendy Bazilian reported:

Sodium is a mineral and a key component of salt. Salt is actually called sodium chloride because it is made up of 40% sodium and 60% chloride… [W]hile your body needs sodium to function properly, too much (typically consumed as salt) can increase the risk of certain health issues.

There can be sodium without salt, but not salt without sodium. A food or drink may contain sodium but no salt. Sodium is an element and a metal. Salt is made of two things, sodium and chlorine, and is not as bad for the body as sodium alone. Sodium does vital things for the body, but unaccompanied and in too large a quantity, it can damage the kidneys and can lead to high blood pressure and stroke risk.

The two main sources, and an additive

Sea salt comes from the ocean and is less processed than table salt. Table salt comes not from tables, but from mines, and is more processed. For many years, sellers of salt have included iodine with their product. Because salt is consumed almost universally, it was seen as the ideal vehicle through which to slip in enough iodine to prevent a massive public health crisis.

If a human thyroid gland is to function effectively, it needs iodine. Without it, the thyroid is unable to properly do its job regarding “metabolic rate, heart and digestive functions, muscle control, brain development, and bone health.” If a fetus does not get enough iodine, the results can include physical deformities and cognitive impairment.

Even with salt vendors doing their best, it is estimated that around two billion members of the earth’s human population experience health issues due to iodine insufficiency.

The food industry

In the USA, the average adult absorbs about 3,400 milligrams per day of sodium, but 2,300 mg (about a teaspoonful) is widely acknowledged to be quite enough. The stodgy old American Heart Association, however, would actually prefer no more than 1,500 mg per day, or less than half the amount actually consumed by the average grownup.

Most of the incoming sodium uses packaged foods and restaurant meals for its delivery system, concentrating on 10 main popular products. Few of those choices contain any form of vegetation, unless you count the sauce on pizza.

Even a responsible eater who never even picks up a salt shaker most likely absorbs way too much sodium. This causes the professionals who spend their lives studying these matters to mention such topics as hypertension, heart disease, and stroke. Oh, and kidney stones. Often, the effects do not manifest until the window of opportunity for redemption has passed.

A question that a reasonable person might ask is, “If sodium is problematic, why don’t the manufacturers just leave it out, and let people salt their food according to taste?” Apparently, because some other, less civic-minded manufacturer will go ahead and include salt, and consequently sell more product.

It’s the Newsiest — Breakfast, Cereal, and Kids

A particular news story appeared almost exactly a year ago, in response to a major journal’s publication of “Nutritional Content of Ready-to-Eat Breakfast Cereals Marketed to Children.” That all-too-typical piece announced that breakfast cereals are “filled with increasing amounts of sugar, fat and sodium,” a statement equally true at this very moment in time.

Does anyone out there believe that the situation has improved since then? If so, we have a very attractive bridge to sell you. Sorry, but no, the shameful trend has not reversed. Oh, and guess what? “The study also found that cereals’ protein and fiber content — nutrients essential for a healthy diet — have been in decline.” That sobering fact is just as true today as it was 12 months ago, and we feel confident in betting that it will be even more true a year in the future.

The original article concerned the analysis of 1,200 new or reformulated cereal products that had appeared on the market over the previous decade and a half. Most of them were products that had already existed, with a few minor tweaks thrown into the mix. Not improvements, just inconsequential changes. Study co-author Shuoli Zhao mentioned the existence of “evolving consumer awareness about the links between excess consumption of sugar, salt and saturated fat and chronic conditions like diabetes, hypertension and cancer.”

And yet…

But somehow, marketing strategy has not reflected any awareness of increasing customer intelligence, or of elevated industrial integrity. Professor Zhao is quoted as saying,

What’s most surprising to me is that the healthy claims made on the front of these products and the nutritional facts on the back are actually going in the opposite direction.

The study found that the total fat content per serving of newly launched breakfast cereals increased nearly 34% between 2010 and 2023, and sodium content climbed by 32%. Sugar content in the newly introduced products rose by nearly 11%, according to the analysis. Kellogg Company, General Mills and Post Holdings, the three largest makers of breakfast cereals in the United States, did not respond to requests for comment.

Well, what remains to be said? Do we really want them to speak aloud the painful truth? “Hey, you virtuous protectors of the consumer have insisted that all information be revealed. Full disclosure has been duly made. We are as revealing as a striptease artist. The public knows everything about our measurements, and ya know what? The public doesn’t give a tinker’s dam.”

There was some talk of attempting to remove some artificial dyes from the U.S. food supply, but whether any serious attempt will be made to back up the notion with legislation is unclear. Speaking of law, no statute anywhere insists that breakfast cereal must be moistened with milk. Try wetting it down with fruit juice and see what happens.

The Center for Science in the Public Interest, a nutrition advocacy group not involved in the study, published some words from its executive director, Peter Lurie, who was surprised to learn that “large food companies have not made a more concerted effort to reduce the sugar, salt and fat content of their breakfast cereals.”

Well, why should they? If there is a word that describes an attitude more apathetic than apathy, that word would describe the industry’s mental state regarding this issue.

Ultra-Processed Foods Cover-up? Part 2

Recommended at this point is to catch up by reviewing Part 1, “Is There an Ultra-Processed Foods Coverup?” What makes information about Dr. Dhruv Khullar’s controversial article even more interesting and relevant is this quotation published less than four months previously:

Robert F. Kennedy, Jr., who may soon lead the U.S. Department of Health and Human Services, has made common cause with some lawmakers by railing against ultra-processed food, pledging to remove it from public schools and limit the use of pesticides, artificial dyes, and, perhaps more dubiously, seed oils.

So apparently, Kennedy underwent some changes of opinion about the matter during the few weeks between that publication and his being made head of the Department of Health and Human Services.

Meanwhile, National Institutes of Health investigator Kevin Hall was recalibrating some of his theories based on the advanced work that he had been doing with volunteers, testing four different diets in turn. Dr. Khullar explains:

When the team served ultra-processed foods that were neither calorie-dense nor hyper-palatable — for example, liquid eggs, flavored yogurt and oatmeal, turkey bacon, and burrito bowls with beans — people ate essentially as much as they did on the minimally processed diet. They even lost weight.

Hall had no choice but to conclude that “Weight gain is not a necessary component of a highly ultra-processed diet,” to which Dr. Khullar appended, “He had, in a sense, refuted his hypothesis again.” And that is exactly what any genuine and honest scientist is delighted to do — to discover that he or she had guessed wrong, or drawn conclusions from incomplete data. A true scientist does not care how many times research has to start over, or how often his or her theories need to be revised, as long as truth is reached in the end.

Dr. Khullar also spoke with the venerable Marion Nestle, and introduces her to readers with this description:

[…] a molecular biologist and nutritionist who started the country’s first academic food-studies program, at N.Y.U., helping to bring attention to the roles that culture, capitalism, and politics play in what and how much we eat.

That apparently is exactly the crux of the whole food policy problem: the role being played by factors politely termed culture, capitalism, and politics, when the clashes of opinion are worthy of cruder but more accurate terms for controversy, that some critics would prefer to use. Dr. Khullar recounts how Nestle reminded him of a historical fact:

During the Second World War, U.S. military leaders were alarmed that many recruits, having grown up during the Great Depression, couldn’t join the war effort because of conditions caused by a lack of nutrients, such as rickets, scurvy, anemia, and tooth decay. “That came as a shock, and the military became heavily concerned with nutrition.”

This is very significant in the light of today’s situation, which includes the ineligibility of many young Americans to join the military because they are simply too fat.

At any rate, Nestle is not entirely on board with heaping blame upon ultra-processed food; but is not a big fan of it, either. (She is, incidentally, enthusiastic about Shredded Wheat, and even dusts it with a bit of sugar — to celebrate the fact that she, and not some corporation, is in charge of deciding the amount.)

Together, the two visited some places where food is produced, learning incidental facts, like how giant blocks of cheese should only be grated at the last minute, because “Pre-shredded cheese spoils faster. This way we can avoid preservatives.” This is exactly the sort of knowledge that leaves in the grim landscape some space for hope.

Is There an Ultra-Processed Foods Coverup?

Today’s post carries on from “The Nutrition That Never Arrived,” which discusses the work of Dr. Dhruv Khullar, as well as his referencing of Dr. Kevin Hall’s highly-regarded study of ultra-processed foods.

The alarming aspect of this topic is that, almost exactly one year ago, CBS News published a piece titled “RFK Jr. aides accused of censoring NIH’s top ultra-processed food scientist.” That scientist of course was Dr. Hall, described therein as “The National Institutes of Health’s top researcher on ultra-processed foods.”

Hall had announced that, after 21 years at his dream job, he was retiring early because, apparently, the NIH is no longer a place where unbiased science can be conducted. The details are rather shocking, according to journalist Alexander Tin:

Hall told CBS News that he was blocked by the department from being directly interviewed by a reporter from The New York Times, asking about recent research on how ultra-processed foods can be addictive.

Apparently, the NIH leadership did not want any comparison made between being hooked on ultra-processed foods and, for instance, your average meth habit — unless the disease manifests in exactly the same way and causes exactly the same effects as hard-drug addiction.

Hall was allowed to reply to The Times with written answers which “were then edited and sent to the reporter without his consent.” This behavior, needless to say, is normally considered highly unacceptable among professionals in the fields of both medicine and journalism.

Then the situation deteriorated even further when the government denied tampering with Hall’s words, and accused him of untruthfulness about the interference, and acted like the material wasn’t very good or worth being concerned about. Hall, however, maintained that his work on the effects of ultra-processed food on carefully observed subjects…

[…] was the largest study of its kind and no previous study had the same level of dietary control, much less admitted them to a hospital to ensure diet adherence…

Meanwhile, the NIH officials maintained that no censorship was in effect, and that any attempt to portray the government’s position as false would be deliberate distortion. In order to avoid being contradicted, the government agency also prevented Hall from participating in a conference on the subject.

At the same time, Susan Mayne, who had formerly been in charge of the food safety and nutrition center run by the Food and Drug Administration, spoke up for Hall’s research.

This whole controversy surprised many observers because just a few months earlier, reporters were writing passages like this one, published in January of 2025 in The New Yorker:

The dirty little secret is that no one really knows what caused the obesity epidemic. It’s the biggest change to human biology in modern history. But we still don’t have a good handle on why.

That was Dhruv Khullar, quoting what had been said to him by Dariush Mozaffarian, a dean at the Tufts School of Nutrition Science and Policy. The implication is that ultra-processed foods have “probably contributed to rising obesity rates,” although other factors also are involved — like changes in the human microbiome and general metabolism, as well as (probably) epigenetics.

Of course, as always, the possibility exists that the situation is influenced by factors that have not even been suspected yet.

The Nutrition That Never Arrived

Pause to visualize a little scenario, a random moment from the days when many young folks actually did pause to rethink their eating habits. The place: a college cafeteria. The girl who has just finished a very healthful lunch blots her lips with a napkin, sighs, and says thoughtfully, “That made me feel… fed.”

It’s a thing that happens now and then, in the presence of genuine nutrients. On the chemical level, the body gets the message: “Something just arrived that will make me healthy, wealthy, and wise.” Millions of tiny cells perk up, and flock to greet and engulf the molecules sent to deliver actual sustenance. A person’s body feels fed. It is an unmistakable sensation, and once felt, never forgotten.

Imagination helps

We have probably all seen something like this in a movie — the scene where a character gets a snootful of an enlivening drug, and shows the immediate effect, so powerful it borders on satire. We can tell that something special just happened. It is the same, on a micro-mini scale, inside the body when an allotment of genuine nutrition manages to get in. Imagine a zillion tiny nutrition junkies suddenly enraptured by a hit of genuine food. It’s the same rush on a different scale of measurement.

Or maybe it is like the scratching of some intolerable itch. Or like the difference between when a baby first wails in frustration, then suddenly latches onto the nipple. Peace at last. Given the opportunity, the body can tell that something extraordinary has just happened — a tsunami of joy, flooding every cell with atoms of pure goodness. When a person gives the body a chance, it can tell.

A closeup view

That is basically what a previous post expressed, in discussing the revolutionary work of Kevin Hall, which “has been cited nearly two thousand times” (as of early 2025, and certainly more by now).

As Dr. Dhruv Khullar wrote in “Why Is the American Diet So Deadly?”,

Hall’s original study […] was the first randomized trial demonstrating that ultra-processed foods disrupt our metabolic health and lead people to overeat. It was hugely influential and is widely recognized as the most rigorous examination of the subject so far.

This is the other side of the coin — the terrible disappointment the body feels at being duped. At being tricked and made a fool of, led to believe that something necessary would be provided, had been provided. Being misled by a scent or even just by a fragment of long-forgotten hope, and then betrayed. Thanks to a scent or a flavor, the anticipation of joy welled up and lasted for a golden instant before being crushed.

Not surprisingly, that work recognizably “sparked controversy and opposition.” The debate over extensive meddling with food began to attract the interest of more scholars, like Dr. Chris van Tulleken. In his book, Ultra-Processed People, these words appear:

With a physiological confusion that barely makes it to the surface of our conscious experience, we find ourselves reaching for another — searching for that nutrition that never arrived.

Sometimes, a phrase absolutely resonates: “Searching for that nutrition that never arrived.” The body has been betrayed. Thanks to the aroma, the bright packaging, the texture of the crispy treats in the plastic bag, and finally their taste… something was promised, but not delivered. That is the junk food experience, which is almost identical to the ultra-processed food experience, because in many cases both categories are applicable.

The experience might be compared with trying to slake thirst with salt water. No matter how dehydrated a person is, that stuff just isn’t going to do the job. In fact, the more of it you drink, the thirstier you will become. Every cell in the body knows the difference, just like it knows the difference between an apple and a merchandised abomination of ingredients that no one in their right mind would want to pronounce or spell, much less ingest.

Disparagement

A critic of Kevin Hall’s work, Walter Willett, led a Harvard study that drew information from “survey data from more than two hundred thousand people,” which resulted in the classification of ultra-processed foods into two major categories. The first contains sugary sodas and processed meats, which increase the risk of cardiovascular trouble.

The second category encompasses “breads and cold cereals, certain dairy products such as flavored yogurts, and savory snacks” that, strangely, apparently decrease cardiovascular risk. (An additional five types of ultra-processed foods apparently do neither.)

When the time came for the government to update its recommendations and endorse or deprecate various food groups, it merely suggested that processed meats be avoided. On the question of whether any amount or impressive source of new information will change American eating, Dr. Khullar seems doubtful:

Our food environments — the type and quality of food that pervades our schools, workplaces, and neighborhoods — influence our diets as much as our tastes do. And our food environments are shaped by our incomes, our government’s choices, and our desire for convenience, as well as active manipulation by the food industry, through things like marketing campaigns and lobbying for agricultural subsidies.

In other words, against what goes on in our neighborhoods, homes, schools, and workplaces — cautious warnings and common sense don’t stand a chance.

Spectacular Obesity Costs Spotlighted

This is a continuation of “Unacceptable Obesity Costs Suspected.” About a decade ago, medical specialists and public health authorities were noticing more and more suspicious correlations between a substance known as bisphenol A (BPA) and various undesirable effects on humans. Chiefly, BPA seemed to be causing childhood obesity, and in some quarters, great interest was generated in the notion of discontinuing its use in products that might ever introduce the stuff into the bodies of children, orally or via any other route.

At the same time, concern grew about the costs that the use of this industrial chemical exacted from society in terms of both human suffering and financial impact. A ton of money was being spent to repair the ravages of BPA on kids, and on young people and adults who had encountered it in early life. Of course, it didn’t do adults any good either, even if, as children, they had managed to escape it.

Neither the first warning nor the last

Late in 2016, amid a climate of escalating suspicion, The Lancet published a report that brought up in no uncertain terms the price tag, in actual money, for tolerating BPA. By then, research had determined that the cost of disease and dysfunction caused by endocrine-disrupting chemicals, familiarly known as EDCs, amounted to more than 1% of the European Union’s annual gross domestic product, familiarly known as its GDP. (In American dollars, this amounted to the equivalent of around $217 billion.)

According to the report,

Exposure to EDCs varies widely between the USA and Europe because of differences in regulations and, therefore, we aimed to quantify disease burdens and related economic costs to allow comparison… Estimates were made based on population and costs in the USA in 2010. Costs for the European Union were converted to US$ (€1=$1·33).

In the United States, the costs accruing to EDCs were calculated to be around 2.33% of the gross domestic product, or around $340 billion. Experts utilized studies from the fields of epidemiology and toxicology to reckon the “probabilities of causation for 15 exposure–response relations between substances and disorders.” The scientists also had much to say about American societal expenses. They determined that…

The difference was driven mainly by intelligence quotient (IQ) points loss and intellectual disability due to polybrominated diphenyl ethers (11 million IQ points lost and 43,000 cases costing $266 billion in the USA vs 873,000 IQ points lost and 3290 cases costing $12.6 billion in the European Union).

The pesticides containing the dangerous chemicals were much more responsible in Europe, implying a need for improved screening there, for “chemical disruption to endocrine systems and proactive prevention.” The known effects of these chemicals on various body systems were already quite concerning, but the discoveries about their ability to wipe out IQ points definitely suggested a need for more awareness in that department. In 2018, PubMed had this to say about a small study:

This is the first study reporting the presence of bisphenols in two distinct regions of the human brain. Bisphenols accumulation in the white matter-enriched brain tissue could signify that they are able to cross the blood-brain barrier.

More recent publications

Another report (among many) supported the idea that exposure to BPA analogues is strongly connected with not only obesity, but also other undesirable health effects, especially in children. Then another one caused a stir by confirming that…

[…] endocrine-disrupting chemicals negatively affect a wide range of systems throughout the human body and have consequences at every life stage.

By now, professionals interested in this question were accustomed to hearing BPA and its relatives described as “forever chemicals,” meaning that once present in the body, they refuse to leave. The chemicals were deemed responsible not only for obesity but also for diabetes and reproductive disorders in both sexes.

On the policy front, the good news was that some substances had been banned; the bad news was that equally harmful chemicals were recruited to take their places. In no sane vocabulary could this be defined as progress.

Two years ago, a Spanish study of 106 children between ages 5 and 10, about half each of girls and boys, indicated that BPA “impacts the gut microbiome of children differently, with normal-weight children showing greater bacterial diversity compared to those who are overweight or obese.” In other words, this endocrine disruptor affects the gut microbiome adversely, leading to a variety of undesirable results.

Yet, the situation is very complicated, with many unclear connections and relationships among various factors. Still, enough is known to create certainty that this chemical and others like it should ideally be kept out of the body altogether — especially in the case of children and even more particularly where babies are concerned.

Unacceptable Obesity Costs Suspected

About a decade in the past, an article published in The Lancet attracted quite a bit of attention, being reprinted or commented on in many related publications. Unlike the vast majority of news about medical research, this piece unashamedly mentioned money, and a spectacular amount of it. Of course, its subject matter was not a complete surprise, having been brought up many times in various contexts, of which a few typical examples follow.

Quite some time ago, it was determined that among the known thyroid system disruptors are PCBs, flame retardants, heavy metals, phthalates, and a manufactured chemical called bisphenol A, familiarly referred to as BPA. This potentially hazardous substance was commonly found in canned food, bottled liquids, infant-care products, dental resins, and other locations, having been put there on purpose with apparent disregard for any adverse results.

As far back as 2012, it was no longer surprising to encounter headlines such as “Association between urinary bisphenol A concentration and obesity prevalence in children and adolescents.” This particular piece of journalism noted that elevated urinary concentrations of BPA were associated not only with obesity but also with coronary artery disease. At the time, it was common for medical writers to note that exposure to BPA was linked to childhood obesity, although hard proof was difficult to come by.

In 2016, journalist Rebecca Lee wrote for CBS News,

The controversial chemical was removed from baby bottles and sippy cups almost four years ago, but is still found in the packaging of many popular food products. Of the items sampled, BPA was found in 100 percent of the Campbell’s products, 71 percent of Del Monte’s and 50 percent of the General Mills cans.

A 2014 study looked at “the effects of long-term paternal exposure to a ‘safe’ level of BPA” in adult male lab rats and their adult descendants, finding that such exposure “disrupted glucose homeostasis and pancreatic function,” but did not seem to affect body weight. Yet there was enough evidence to support a strong suspicion that chronic exposure to supposed “safe” amounts of it was not actually all that safe.

A year later, BPA was being mentioned as deserving high priority for further study as a health risk for humans because of the high degree of exposure that seemed bound to affect people of all ages, one way or another. Suspicion involved not only reproductive toxicity, but other side effects, “including liver damage, disrupted pancreatic β-cell function, thyroid hormone disruption, and obesity-promoting effects.”

Early in 2016, BPA was still a food industry favorite to improve food can linings and water bottles. Science writer Bailey Kirkpatrick described how, if only grownups were affected, that would be serious enough, but the stuff was also extensively used in baby feeding bottles and toys that toddlers famously gnaw on. Not to put too fine a point on it, BPA was going into their mouths and from there to other parts of their bodies. Apparently, not much thought had been expended on that aspect of the manufacturing trend.

Even though not proven at the time to affect body weight, there were plenty of other issues, like how the chemical could affect the human reproductive system by “mimicking estrogen, binding to nuclear estrogen receptors and even androgen receptors.” There were also issues and suspicions concerning connections to diabetes, cardiovascular disease, cancer, brain damage, prostate gland trouble, and rising obesity rates.

It was also noted, with alarm in many quarters, that BPA disperses into the air and, equally concerning, into the water, which, as any classroom globe will demonstrate, knows few borders and embraces the planet from every angle. Concerned professionals also spoke of lax oversight, the absence of adequately transparent labeling, and, as always, insufficient data. Still, the available evidence was enough to move the Food and Drug Administration to forbid the presence of BPA in the packaging of baby formula, even if it did prevent metal corrosion.

The Case of the Politically Incorrect Teacher

There is more to know about the incident in which a high school teacher caused quite a stir by inserting questions that referenced obesity into an exam that the students were, of course, required to take. An understandable first reaction might be, “Just a moment, are we to understand that the gent educates young people about an obesity-related field, like nutrition or exercise? Is he perhaps the gym teacher?” But no: Tom Chan teaches math.

To digress for a moment from that odd discrepancy, it should be noted that the entire San Francisco United School District, where Lowell High School is located, enjoys an apparently well-functioning mechanism for conscientiously feeding children of all ages, several times per day if necessary. The menus, published via a special website, include such details as the calorie content of upcoming meals.

The financial details are unclear, but it seems to be free for most or all students. That is a topic for another day.

The intriguing question that comes to mind, the real head-scratcher, is, “How and why would a teacher of mathematics insert material, whether intended as humorous or not, about obesity, into a compulsory test?” Learning more about the circumstances of the accusation of wrongdoing and its consequences does little to clear up that question.

The status quo

All along, in the course of a more than 20-year teaching career, most of Mr. Chan’s kids have rated him highly, to the point where…

For many of us, Mr. Chan was not just a teacher; he was a source of encouragement and someone who genuinely believed in our success.

A former student wrote to the San Francisco Chronicle that Chan “went above and beyond in ways that are rare.” A report from SFist.com noted that many students “brushed his humor off as being ‘bad dad jokes,’ which the students interpreted as Chan’s way of making math more fun.” (Just to be clear, the phrase “bad dad jokes” denotes corny humor, not abusive fathers.)

Recently, for some reason, talk was going around about particular test questions that bothered some students, and consequently some parents, and the authorities. Two items were of particular concern, problems that involved “a ‘fat kid’ punted into the air and the cost of dating girls based on their weight.” As more individuals within the system became aware of the disturbance, more of them agreed that Chan’s language and behavior were perceived and received as fat-shaming, and also sexist.

When the press informed the public, the feathers hit the fan. Some students had never been comfortable with their math teacher’s style all along, and the ensuing publicity encouraged them to speak up. With public attention focused on the matter, the authorities had no choice but to suspend him pending further investigation.

Meanwhile, additional evidence was brought forward. Both teens and adults who had previously not felt that they needed to strictly follow the “See Something, Say Something” policy hardened their attitudes and added their observations and experiences to the pile. One report mentioned a 9th-grade algebra quiz question that had something to do with giving candy to a “fat kid.”

But then word got around, not only about this particular test, but earlier ones, as well as language that had been used in the classroom and elsewhere. A citizen remarked in an online forum that Chan had been known to “make gross generalizations about people who speak Cantonese,” which is not a positive quality.

Yet at the same time,

Hundreds of former and current students immediately defended Chan after the Chronicle’s coverage, signing a petition and urging officials to reinstate him.

A parent named Caimán Dorado wrote to SFist.com,

My kids, 2 girls!! …remember Mr Chan’s quirky jokes and say WAS NOT A BIG DEAL. He was popular to the kids boys and girls, a good creative teacher… These almost adult high schoolers who spend their lives online, understood Mr Chan was just trying to make calculus more creative interesting and fun.

Another parent wrote,

To be fair, when my kids were going to Lowell, the math and science teachers used a lot of goofy examples like that to keep the students engaged, although that was more in Physics and Calculus, as I recall.

But some current and former students went the other way, recalling additional details that made them uncomfortable, and sharing them with the student newspaper. Worse yet, the school authorities also cited as a reason for the suspension “other behaviors,” which various publications have mentioned, hinted at, or confirmed as fact.

It was common knowledge to anyone who frequented the same social media sites that Chan commented on some female students’ posts and sent them direct messages. (The journalist did not mention whether any male students received the same extracurricular attention.) Apparently, he had been heard to say, “Girls are either pretty, or they can do math,” which sounds pretty sexist, or at the very least, unnecessary and inappropriate.

This item does not sound good at all. As stated by SFist.com,

Some parents are also unhappy that he posted “Grades vs. Dignity” videos on YouTube of students dancing in exchange for extra credit.

At any rate, the authorities placed Chan on “indefinite leave,” and by March 25, he had resigned.

Other Expenses, Like Shame and Blame

We have been discussing the fiscal costs to society (namely, us) of obesity. But what are the psychological costs of shame and blame, and who should bear those costs? Who should be held responsible for the friction — the administrators of a particular school, the parents, the voters, the students, or all or none of them?

Psychology is a tricky subject, because definitions of responsibility and of psychological damage vary from place to place and even within a single community. Furthermore, every related expanse, to whatever degree it originates in the mind, contains the possibility of costing real dollars eventually, especially when a publicity-attracting event like a lawsuit or the firing of an administrator comes along.

When the “shame and blame” bills come due — as they inevitably will — dollars will be demanded, and paid. First in line to empty their wallets are parents, who might pay for “fat camp;” for the services of a mental health professional in person or online; for two entire sets of clothing for a child whose weight fluctuates wildly; for pricey “health foods” in hopes that a change of diet will do the trick; or who entertain the mistaken belief that a child’s away-from-home food consumption can be controlled.

On the public stage

The example might be cited of an obese child soaking up public money in order to try losing weight, and what a disgrace it is, because the funds could have been used instead for some other child who is fighting a serious infection. How unacceptable it would be for one to suffer because limited resources are being used for the other! A crudely unsympathetic adult might wonder why a kid who got fat by greedily eating everything he could get his hands on should receive help, to the detriment of a poor, innocent child who suffers an illness that she or he was not responsible for contracting.

Is that fair? Aren’t the wrong sort of people depleting public resources that more rightfully belong to the more deserving? (Apologies to the reader, but some folks do see it this way.) But to mention that view is an effective segue into the topic of blame and shame, and how much those impulses influence the entire field of obesity in myriad ways.

West Coast discontent

This issue was recently the cause of public censure when a teacher’s actions were investigated because of exam questions that some critics deemed “inappropriate.”

Lowell High School, part of the San Francisco Unified School District, is known in one context
“one of the highest performing public high schools” in California. Math teacher Tom Chan composed some exam questions that were deemed “inappropriate” because of content that struck critics as being sexist and fat-shaming. According to the San Francisco Chronicle, students were tasked with calculating “[…] how much it would cost to pay for dinner for girls who weigh 120 versus 220 pounds.”

Worse yet, another quiz question was said to be titled “Mr. Chan vs. The Fat Kid (part 2).”
The entire school system has an anonymous system known as “See Something, Say Something,” through which concerned participants can bring questionable actions to the attention of trusted adults.

Judging by its informative website, Lowell High appears to be an outstanding institution. Its language department encompasses eight languages, and the Visual and Performing Arts Department is said to be exceptional. Whopping 27 sports are practiced by 32 teams; 100 clubs and service organizations are active; and the institution boasts programs that specialize in Wellness, Peer Resources, and CSF Tutoring.

Most importantly,

Lowell endeavors to create a just and equitable society where individual responsibilities are clearly defined and personal rights guaranteed. It endorses the concept of an integrated school where cultural and social diversity enrich the lives of all students.
