Rob Sharp, writing online for Independent.ie, asks, "Are you a cowering, diet-obsessed wreck, meticulously measuring your carbs and counting out individual grains of salt granules on to your plate?" He then offers hope--a book by professors Stanley Feldman and Vincent Marks who attack media scare tactics and so-called scientific wisdom, including misconceptions about salt.

Eating salt is not bad for us

Many scientists, think that too much salt can cause everything from heart attacks to strokes and kidney disease. Feldman and Marks believe the risks are overblown. This is because of our reliance, they say, on antiquated medical research in which patients were treated for high blood pressure with a lowered salt intake (before drugs were available).

"This seldom worked," they write. "Nevertheless, the myth has persisted." When results of 11 of the most scientifically credible studies of the effects of salt in the diet were analysed by the internationally recognised Cochrane Collaboration, the effect of salt on blood pressure was found to be negligible.

Salt is an essential food and without it we would die. Sweating is impossible without it, and strenuous exercise by those with depleted levels of salt can lead to overheating and death.

Just look at the Japanese, say the professors. They have double the European salt intake, yet have a longer life expectancy and less problem with blood pressure. "Lots of salt is nowhere near as bad as we are led to believe by campaigning groups," says Marks.

We might add that it is not just the Japanese that have high salt diets and positive health outcomes. It is widely known and accepted that the Mediterranean diet is high in salt, yet the Mediterranean people have the world's best cardiovascular health. The diet is so healthy that the National Heart, Lung and Blood Institute (NHLBI) used it as a model in their famous DASH Study (Dietary Approaches to Stop Hypertension). The study confirmed that the Mediterranean/DASH diet was healthier than the typical American diet and effectively reduced blood pressure (BP).

In fact, we can take this one step further. Because a diet rich in vegetables is key to good health and because vegetables are much more flavorful with added salt, a healthy diet is much more easily realized by using salt, rather than trying to reduce it. As a mom, I spent years luring my children to eat their vegetables by adding salt and butter and, if necessary, ranch dressing. Hint for getting a finicky, rambunctious three year old boy to eat broccoli: Call the broccoli "trees", the salt "rain" and the ranch dressing a "river". Desperate times call for desperate measures! No damage done. He's a healthy 21 year-old now and has never referred to broccoli as trees in public, but he does like vegetables.

Message for the day: Scare stories might be bad for your health.

Royalty speaks ... in a recent interview . Here's a preview:

Homer says, "Salt belongs to the sphere of divine and stands far above human." I truly believe salt is the fifth element due to its importance in life. Salt is a basic human necessity, our bodies cannot function with out it. Salt was used to preserve food, think of the " Magazzini del Sale " (warehouse of salt) in Venice. It was a form of currency, a derivative of the word "salary." It has been used in the past to bring good energy and ward off negative influences and has also been synonymous with prosperity and health since ancient times. When I began incorporating salt into my paintings I found magic occurring in each single crystal. So I began amalgamating it with the colors I would create, and it seemed to pronounce their essence exponentially. I adopt the minimalist philosophy of "less is more" and when experiencing the art one is able to fully appreciate texture and color at its height. I capture the soul of this mystical element to share, and as I allow my eyes to trace the natural movement I get lost in its beauty and power.

William McGurn's op ed in today's Wall Street Journal on "Harry Reid's 'Evil' Moment ," brings to mind the ongoing similar campaign to de-legitimize dissent from the orthodoxy of salt reduction. McGurn recalls the mainstream media outrage when U.S. presidents described the Soviet Union as an "evil empire" and North Korea, Iran and Iraq (at the time), an "axis of evil." More recently, when House Speaker Nancy Pelosi accused those opposing President Obama's health care recommendations as "un-American" and Senate Majority Leader Harry Reid following in her train calling those protesting the "public option" health care proposal "evil mongers," the media have been silent about the characterization.

Indeed, it does seem a bit over the top to use the same rhetoric to describe opponents in a domestic American political debate with the same terms as truly "un-American" regimes that employ (or employed) cruel repression as their modus operandi.

What struck me in the McGurn column, is the parallel tactic being employed by proponents of universal sodium reduction in an attempt to deny the controversy among scientists about the scientific underpinnings offered to support having all Americans eat less salt. When the Royal Society of Chemistry conducted a debate in London several years ago, I laid out the evidence amassed by renowned scientists in peer-reviewed medical journals showing the lack of evidence of a health benefit for reduced-sodium diets; my opponent, Dr. Graham MacGregor, eschewed the science and reminded the audience that I was not a medical doctor and my salary was paid by salt producers. When the president of the International Society of Hypertension used his presidential address to decry the misdirection of anti-sodium proponents in focusing on blood pressure rather than health impacts, the mainstream groups pointed out that the Salt Institute has consulted with this acknowledged expert -- even though the consultancy was unpaid -- as if to say that somehow our seeking after the best quality scientific advice and the doctor's proffering his expertise to those dissenting from a view to which he had repeatedly objected is illegitimate.

Just as Americans should recoil from attempts to intimidate debate on legitimate Congressional debate, so should we be concerned at attempts to delegitimize the public health nutrition debate on sodium and health.

The “gold standard” in determining how much sodium you eat is how much you excrete. If healthy, the kidney processes many times over the amount of sodium a person ingests but excretes almost exactly the amount taken in. “Everyone” knows that! All medical studies of dietary sodium are concerned about how to measure intake since sodium isn’t something discrete like a banana or apple; it’s consumed in very small amounts in virtually everything. Dietary recall has become a refined art, but most scientists agree that even the best recall techniques pale in accuracy to measuring urinary sodium – the “gold standard.”

In recent years, however, much like other “truths” we’ve “known” about sodium, our knowledge is becoming a bit less ironclad. The May-June issue of Seminars in Dialysis carries an iconoclastic article by German nephrologist Jens Titze, “Water-free sodium accumulation ” questioning the concept that the amount of steady-state sodium in the body is unchanging. Titze suggests that “large amounts of Na+ can be accumulated” which “provides an extrarenal regulatory alternative in the maintenance of body fluid volume and blood pressure control.” Titze’s conclusion:

The physiology and pathophysiology of body Na+ distribution is more complex than believed. Therefore, clinical concepts based on oversimplified two-compartment models of Na+ balance must be experimentally re-evaluated.

Earlier studies of German astronauts and others have suggested much the same. It’s far too early to jettison our reliance on urinary sodium measurement, but it should remind us that science is ever evolving as we push back the shadows of the unknown.

I’m off to China in a few weeks for a worldwide Salt Symposium. In preparation, I’m auditing a course on Chinese history (“From Yao to Mao” --Tang Yao, not Yao Ming!). One of the study segments compares Confucianism with Taosim and the lesson seems apropos. Confucian thought was very orderly and hierarchical; people should conform to the “known.” Tao thought, to the contrary, is more skeptical, questioning whether we really understand the full nature of anything we think we “know.”

Thus, the “gold standard” of urinary sodium and concept of sodium homeostatis are Confucian and Titze and other skeptics have a Taoist strain.

With regard to our current controversy over dietary sodium, the National Heart, Lung and Blood Institute would represent the Confucian approach of bestowed truth while groups like the Cochrane Collaboration and other skeptics about conclusions being drawn from available evidence, embody a Taoist approach.

All of us, whether we readily accept and revere authority or revel in the flaws inherent in our quest for understanding, should use these small events as useful reminders of the larger need to remain humble and teachable in our approach to life.

The UN Development Program (UNDP) recently published its fifth Arab Human Development Report reviewing the state of affairs in the Arab world. Recently returned from a global meeting on salt iodization in Cairo, I eagerly plumbed the report, particularly Chapter 6 which described nutrition challenges. In that discussion, I found the pattern of the entire report -- and, I hope, a lesson for the rest of the world about the value of competitive ideas.

Chapter 6 on nutrition references iodine deficiency, but fails to make the iodine/brain development connection. It says lack of iodine and other vital nutrients "weaken children's bodies and impair their immune systems" and "reduces productivity." A missed opportunity.

The "missed opportunity" theme pervades the report. Fouad Ajami , professor at the School of Advanced International Studies at Johns Hopkins University, calls the report an "autopsy of the Arab condition," adding:

The first of these reports, published in 2002, was treated with deference. A group of Arab truth-tellers, it was believed, had broken with the evasions and the apologetics to tell of the sordid condition of Arab society—the autocratic political culture, the economic stagnation, the cultural decay. So all Arabs combined had a smaller manufacturing capacity than Finland with its five million people, and a vast Arabic-speaking world translated into Arabic a fifth of the foreign books that Greece with its 11 million people translates. With all the oil in the region, tens of millions of Arabs were living below the poverty line. Little has altered in the years separating the first of these reports from the most recent.

Ajami commends Iranians contesting the announced results of that country's recent presidential election. He would probably find joy in the purple-inked fingers of Iraqi voters as well. But he condemns (democratic, surely, not Islamist) activists in other countries for the ineffective opposition to authority. The lessons he draws are about truth-telling and free public discourse. While lamenting that the powers-that-be have eradicated dissent, he goes one step further, which struck me as instructive in our public health nutrition debate elsewhere in the world, particularly in the US and the UK. He declared:

The simple truth is that the Arab world has terrible rulers and worse oppositionists.

Let me use the contentious salt and health debate to illustrate this transference. In our instant debate, there are those who contend that because salt is related to blood pressure (lowering salt will reduce the blood pressure of some -- and more than the number for whom low-salt diets increase BP) and because populations with lower BP have lower risk of cardiovascular events like heart attacks and strokes, that this "proves" the efficacy of universal salt reduction. Opponents of a population intervention argue that studies of heart attack rates and cardiovascular mortality don't show those on low-salt diets fare better -- often they are placed at additional risk. Moreover, no amount of behavior modification has worked and the latest strategy, coercing the food industry into lowering the sodium density of its products, is untested and flies in the face of research showing that the unconscious brain sets the appetite for sodium.

The "rulers" here embrace the "sodium hypothesis" and endorse sodium reduction. Unfortunately, like the entrenched rulers of the Middle East, they are trying to stifle dissent and deny the legitimacy of the scientific debate. No matter that a recent presidential address to the International Society of Hypertension described the fundamentally-flawed basis for U.S. policy. No matter that the prestigious Cochrane Collaboration , inventors of "evidence-based medicine" finds no basis for the U.S. policy. No matter, even, that the government's own U.S. Preventive Services Task Force agrees that no evidence supports the strategy, the "rulers" press forward. In this regard, they are "terrible rulers," to use Ajami's term.

Worse, where is the opposition? If "the Arab world has terrible rulers and worse oppositionists," are we any better? True, some have decried the assault on sound science (see Taubes, "The (Political) Science of Salt ") and others lament the "nanny state " and "food police " second-guessing individual food choices and steamrolling the food industry on the salt content of its food. But until Kellogg's (html 54.86 kB) recently raised the prospect that the emperor had no clothes, the food industry has largely been content to ignore the science and pump pricier low-sodium foods into the marketplace, fellow-travelers willing to claim the government-bestowed "health" claim in return for their silence on issues of quality science.

Too often we point with disdain at the failings of others when what's needed is a harder look in the mirror. If we want science to guide health policy, we must become "truth-tellers" too.

Rep. Earl Blumenaur (D-OR) didn't get his party's "no middle class tax" memo. His new water infrastructure bill would meet the new spending demands with taxes on bottled beverages -- water and soft drinks (alcohol exempted; he likely has wine-grower constituents), soaps and detergents, toilet paper and water softeners. Sounds like a middle class tax to us. See sections 4171 and 4172 of his bill HR 3202 which has been referred to four House committees, including the tax-writing Ways & Means Committee. Let's hope it's just another PR ploy.

Featuring stories on a new report on urban transportation mobility, Kellogg's decision to take on the Dietary Guidelines Advisory Committee on sodium and health, the new taxes required to pay for healthcare, how some news accounts adopt a "glass half empty" approach to assessing health progress, and how treating HBP below 140/90 may make no difference, the August issue of SI Report is now available (html 54.86 kB) .

Brian Wingfield of Forbes Magazine recently wrote the following in his article, “Fat Tax Could Be Panacea For Health Reform:”

According to a 73 page study released Monday by “experts” at the Urban Institute and the University of Virginia , aggressive public policy interventions that helped bring down tobacco use could be modified and applied to fight obesity, including

• imposing excise or sales taxes on fattening food of little nutritional value, as the tax on cigarettes has proven to be the single most effective weapon in decreasing tobacco use;

• putting graphic, simple labels on the front of packaged foods showing their nutritional value in a form that consumers can easily understand and use;

What is a fattening food that should be taxed? A Twinkie at 150 calories and 5 grams of fat per serving? Perhaps we ought to go upscale and consider a serving of high end chocolate mousse pie at 247 calories and 15 grams of fat per serving - obviously deserving of a higher tax. If you're not interested in dessert, then how about a serving of fruit or vegetables. A convenient compromise would be a serving of avocado, which is botanically a fruit, but usually served as a vegetable. A serving of avocado is 240 calories with 22 grams of fat! Clearly anything with more than 20 grams of fat per serving should be dinged with a surtax above and beyond the normal fat tax.

It goes without saying that green foods (fruits and vegetable) contain the lowest levels of fat and should be exempt from tax.

Obesity is the result of consumption of calories in excess of calories expended. It is not the result of the types of foods consumed. Vegetarians and vegans are known to be very concerned about their health and are defined by the green foods they eat. Yet, obesity is a problem among this category of green food consumers as well. The June 2005 issue of The American Journal of Clinical Nutrition describes this in the article. “Risk of overweight and obesity among semivegetarian, lactovegetarian, and vegan women .” Overweight or obesity (BMI 25) was 29% among both semivegetarians and vegans, and 25% among lactovegetarians. For them, vegetarian and vegan foods are fattening. Should they be taxed?

Using the reduction in tobacco use as a model to influence food choices is an absurd notion. Tobacco use causes cancer. There is no strategy that tobacco consumers can employ to mitigate its negative health impact, other than complete cessation of use. Eating food does not cause cancer nor does it result in obesity. Eating an excess of calories over what is expended does result in obesity. It’s not the type of food that is the problem, it’s the amount that’s consumed, as demonstrated by the vegetarian/vegan example above.

Consumers have to be informed on all aspects of obesity and then be left to their own personal choices. If eating a twinkie makes me happy and I burn off any extra calories by cycling around the block a couple of extra times, then that is my priviledge. I prefer that to not eating the foods I enjoy, then getting into a dour mood and kicking the first squirrel that comes into reach. A tax on any class of food or beverage is nothing more than a sumptuary law, no different than all the other sumptuary laws enacted throughout history that have failed. Social authoritarianism does not work and can lead to dangerous unintended consequences. Taxing sugar-sweetened beverages will drive children to drink cheap concoctions laced with artificial sweeteners. Do we know the long tem consequences of a lifetime of artificial sweetener consumption or is it simply enough to put a warning label on the product (as in the case of saccharin)? Will taxing of higher fat foods drive consumers to overeat more fruits and vegetables? Fruits and vegetables have high fiber and phytic acid levels, which means that other nutrients in the diet may not be digested properly.

The fat or beverage tax is another simplistic attempt to arrive at a superficial solution to a lack of a rational food culture. It is the abandonment of confidence in the average consumer’s ability to think and make free and informed choices once they are educated.

It is far better to follow the old proverb; Give a man a fish and you feed him for a day. Teach a man to fish and you feed him for a lifetime.

Not too little - not too much…….the Summer Salt and Highway Deicing Newsletter (pdf 450.51 kB) focuses on the merits of calibration for solid material spreaders and liquid distribution systems. Fundamental concepts, types of spreaders and controllers as well as the guidelines for assuring accuracy during the calibration process are reviewed.

This is no joke. Good news used to be a cause of celebration. Too often, today, it conjures up worry and concern as we sophisticates "know" it must be "too good to be true." Sometimes, actually, it really is just plain good news. We need to learn better how to appreciate our blessings, our progress.

Last week, several stories illustrated the point.

In Canada , researchers reported on a study that showed that the rate of coronary heart disease incidence is decreasing. The authors -- and the media -- played the story that CHD increased by 10.5% from 1994-1995 -- while leaving unreported that the population of Canada increased by 12.5% over the same time span. Good news/bad news.

Also last week, the British Medical Journal reported that over the past 20 years, CHD in the UK has fallen 61% in men and 56% in women. Celebrate? No, the authors -- and the media -- emphasized that the rate of decline seems to be slowing, a cause for concern.

North Atlantic polemicist Brendan O'Neill, writing in Spiked , pointed out just-released U.S. Census data showing that within a decade Americans over 65 will outnumber those ages 5 and under for the first time in history. He makes my same point: why not celebrate that more of us are living longer (and better) rather than complain about the "burden" of golden-agers?

It may be hard sometimes to see that "every cloud has a sliver lining," but we certainly can do a better job in appreciating what we have and the progress we have made in so many ways. Every cloud is not a nimbus cloud. The bad news is that we're losing our ability to appreciate good news. That's no joke.

The Canadian Medical Association Journal (CMAJ) this week carried a story, released widely in the media, implying drastic slippage in Canadians' cardiovascular health status. Douglas S. Lee and colleagues on the Canadian Cardiovascular Outcomes Research Team reported that, from 1994 to 2005, 19% more Canadian men suffered from heart disease (and 2% more women). They conclude: There is an increasing prevalence of heart disease and risk factors for cardiovascular disease in Canada."

Everyone would love to report that no Canadians suffer heart disease, of course, but the researchers report nearly all groups in Canadian society suffering "significant" increases in heart disease and the "risk factors" which predict adverse health outcomes. Trouble is: that's not what their data really showed.

The Canadian population is split nearly evenly between males and females (49.6%/50.4%) so the 19% increase in heart disease among men and 2% among women comes out to about a 10.5% population average increase over the 12 year period. But Canada's population during those years grew from 29 million to more than 32.6 million, an increase of 12.5%. So, actually the rate of heart disease in Canada has actually continued to improve. Two years ago, our Salt and Health (pdf 500.04 kB) newsletter displayed these figures graphically (see Figure 5).

It's unfortunate that journalists didn't look deeper than the news release and author-prepared abstract for the real story.

The authors are concerned about trends in recognized risk factors that run directly counter to the pattern in heart disease incidence. Diabetes, hypertension and obesity are all on the rise, though, regarding obesity, Canada seems the reverse of most other developed societies where obesity is more common in lower socio-economic groups; that trend is exactly reversed among Canadians.

The authors' primary concern is that risk factors among the young are a cautionary finding for future trends, but they give short shrift to the dramatic and long-term gains that their study documents.

Earlier this week, the National Institute of Aging released "Tips for Older Adults to Combat Heat-Related Illnesses " noting that the "risk of heat-related problems increases with age." That's a timely warning as summer's sweltering days lie immediately ahead. While timely, the advice is incomplete and incomplete for the reason of ensuring the advice is politically-correct -- if not medically correct.

Older people need to heed the warning. They are at extra risk of hyperthermia as the NIA warns. And, in fairness, buried in the release is the notation that low-salt diets "may increase their risks."

Rather than include any action steps to heat-threatened seniors to safeguard their salt (and total electrolyte) intakes, however, NIA contents itself with advice to consume water and fruit/vegetable juice. Replacing fluids without replenishing electrolytes (like salt) can be fatal to those suffering hyperthermia, leading to hyponatremia. Every summer, thousands die not appreciating that hydration is critical and proper hydration requires attention to electrolyte balance.

The American Medical Assocation's JAMA journal examined the situation in women and documented the importance of salt therapy:

Chronic hyponatremia is a common clinical problem in the elderly, particularly among women. Mortality is substantial. It is now well accepted that acute symptomatic hyponatremia (hyponatremic encephalopathy) can result in death or permanent brain damage. While failure to institute active therapy (intravenous [IV] sodium chloride) in such patients may lead to increased morbidity, IV hypertonic sodium chloride therapy is both safe and effective in preventing hyponatremic brain damage.

Seniors would be well advised to take NIA's warnings seriously, but take the agency's remedial advice with a grain of salt.

Show me the money!

Reuters reported on Monday July 20, that two years after New York City declared war on artificial trans fats, nearly all the city’s restaurants had successfully cut the artery-clogging fats from their menus, according to city health officials. Artery-clogging fats? The story went on to say that trans fats have become notorious because they not only raise so-called "bad" LDL cholesterol, but also lower levels of so-called "good" HDL cholesterol. In 2006, before the health department ban, half of New York City's restaurants were using trans fats. By November 2008, less than 2 percent were, according to Dr. Sonia Y. Angell and her colleagues at the Department of Health in their article in Annals of Internal Medicine .

What they could not say was how this initiative actually helped the citizens of New York. The presumption is that ridding the food supply of trans fats will definitely improve the cholesterol levels of millions of people. Improving the cholesterol levels should result in reduced cardiovascular disease, but has it ? Since most New Yorkers eat in restaurants, often several times a week, there should be a significant decrease in the number of people that will have heart attacks and die - right? That is what everyone is after - right? And certainly with all the modern statistical tools we have available and with a precise knowledge of the exact date that the trans fat ban went into effect, we must be able to demonstrate the health benefits that accrued from the New York ban. Surely we can be spared the lame “cardiovascular disease is multifactorial, therefore we can't really tell if the ban worked" excuse. The fact is there are no metrics in place to measure what should have been the primary goal of the ban. The people behind the ban were arrogant enough or insensitive enough to dispense with the trivialities of actually determining if their initiative really accomplished anything. There is nothing in place to "Show me the money!"

For 1500 years, the world believed in 'spontaneous generation' simply because the Greek philosophers said it was so. Francis Bacon, often referred to as the father of the scientific method, didn't buy it and effectively said, "Show me the money!" Credibility has to be based upon evidence.

The scientific integrity of this country and its institutions is declining because we are associating credibility with institutions rather than with evidence. We accept notions without demanding evidence. It may well be that there is spontaneous generation and that New York's citizens have actually benefitted from the trans fat ban, but until there is objectively-obtained evidence to confirm this, the only ones who have really benefitted are those individuals and institutions who have garnered free publicity. Consumers should be served a lot better than that!

Remember what Santayana said about those not knowing history needing to repeat it .

The New York Times archive yields this 60-year-old headline (February 20, 1949): "CITY STOPS THE SALE OF SALT SUBSTITUTE ; But Mustard Says No Deaths Have Been Reported -- Public Warned of Danger." The study reports how the NYC Health Department withdrew approval of the very best taste-alike salt substitute ever known: lithium chloride. The City Health Department was interested in salt reduction apparently (the City noted that lithium chloride was being "used widely as a substitute for common table salt"); but just as apparently, didn't do their homework. Lithium chloride may taste like salt -- and no other salt substitute has been found that matches its taste -- but it's a deadly toxin and the substance administered to execute death row prisoners. As we've told the NYC Department of Health: first do no harm (pdf 53.83 kB) . We didn't realize they'd already been put on warning.

A week ago, a blogger blatantly misrepresented "facts" from the Salt Institute. Within hours we filed a comment correcting his blog post. Comments on his site are "moderated," however, and, now a full week later, he has declined to post the badly-needed correction. I cannot let its inaccuracy pass without response.

Mr. Weck writes "Food Trends 2009: Food Business Resource's complete food trends guide 2009" and on July 9 posted "Easy on the salt ." He told his ostensible food service industry audience:

With all the talk of sodium and heart disease, I have a hard time even picking up a salt shaker anymore without grabbing my chest, gasping for air and seeing my life flash before my eyes! It’s no wonder Americans have grown increasingly fond of salt. According to American Salt Institute, “Salt intake has increased by 50% over a period of 15 years beginning in the late 1980’s.” If that’s not impressive, I don’t know what is!

Mr. Weck misquotes us; no one associated with the Salt Institute has ever made such a representation. It's a total fabrication.

Americans have always been "fond of salt," but we are eating the same amount of salt today that they ate in the late 1980s. Indeed, we have eaten the same amount for more than a century. Before the early 1900s, we lacked instrumentation to make accurate measurements. True, we get the salt from different dietary sources -- far more from foods prepared by others and far less from foods we prepare ourselves at home -- but the amount of sodium, for which we have accurate measures, is about 3,400 mg/day. All that doesn't come from salt; most nutritionists calculate that about 10% of it occurs naturally in the foods we eat. Thus, the average American is consuming about 7.9 grams of salt per day today.

Mr. Weck warns: "As the public becomes increasingly aware of this issue and the severity of its consequences if ignored (i.e. heart disease, stroke, kidney disease, high blood pressure, obesity, ad infinitum), the entire food industry is going to be in a heap of trouble." He confesses his own employer promotes low-salt foods. Since the evidence fails to show adverse health outcomes from current salt levels (any blood pressure impact is canceled by offsetting changes in other risk factors like rising insulin resistance, plasma renin activity and increased aldosterone production) and since all evidence suggests that salt appetite is regulated by unconscious brain directives, not conscious decisions, it may be that Mr. Weck's company may be "in a heap of trouble" when Americans begin to realize that companies touting low-sodium foods to tap politically-correct salt avoidance stand accused of fomenting fears to promote a hidden agenda of increasing Americans' food intakes. While salt intake levels remain unchanged, our consumption of calories trends steadily upward.

Perhaps I should have more patience and empathy for someone whose feeble cardiovascular condition induces chest pains simply by picking up a one- or two-ounce salt shaker. Such a rare condition deserves medical attention; it separates Mr. Weck from healthy Americans.
