A new study published in the Journal of the American Medical Association (May 4), reports that among 3,681 study subjects followed for as long as 23 years, those on a low-salt diet were more than 50% more likely to die from cardiovascular causes than study subjects who consumed substantially more salt.

A new study in the American Heart Association journal Hypertension reports that consumption of one sugar-sweetened beverage (SSB) per day increased the systolic/diastolic blood pressure among study subjects (N=2,696) on average by +1.1 mm Hg/+0.4 mm Hg. The researchers conclude that SSBs are directly associated with blood pressure. We conclude that this study is meaningless.

Even accepting the study results at face value, they are of no clinical significance. The average BP in the one-SSB-per-day-group was 119.5/74.0 — under the ideal BP of 120/80. In the more-than-one-SSB-per-day group, mean BP was 122.5/75.5 — again, perfectly normal. Moreover, the study did not link SSB consumption with any clinical health effects.

You’ve heard of Coke Zero; this study is Hypertension Zero.

If you thought the food nannies’ appetite for dictating what beverages you may enjoy would be satisfied by their crusade against regular, sugar-sweetened soda, think again. Their new battle cry is shaping up to be, “None of the calories but all of the sin.”

Government-funded researchers led by the University of Texas’ Jennifer Nettleton analyzed diet and health data collected from 6,814 adults and reported in the journal Diabetes Care (Jan. 16) that daily consumption of diet soda was associated with “significantly greater” risks of type 2 diabetes and “metabolic syndrome.”

Although the researchers perfunctorily acknowledged that their study doesn’t prove a causal connection between diet soda and health problems, they nevertheless spent a great deal of space suggesting why their results might be plausible.

They hypothesized that artificial sweeteners may: “increase hedonistic desires for sweetness and more energy dense foods”; reduce dietary guilt and facilitate the overconsumption of other foods; and affect biological processes related to insulin resistance, glucose regulation and weight gain.

Though they acknowledged that “empirical data have not universally supported” the first two hypotheses and that studies are “lacking” concerning the last hypothesis, none of this seemed to dissuade them from proclaiming that their results were consistent with “accumulating evidence of the existence of these associations.”

But rather than hypothesizing — or fantasizing — about why their results might be plausible and consistent, they should have taken a harder, more objective look at their data and statistics.

First, their reported statistical correlations between daily diet soda consumption and diabetes and metabolic syndrome — 67 percent and 36 percent increases in “relative risk,” respectively — are too small to be considered as reliable indicators of any sort of real-life associations. As the National Cancer Institute once went to pains to point out in a press release, “In epidemiologic research, [increases in risk of less than 100 percent] are considered small and usually difficult to interpret. Such increases may be due to chance, statistical bias or effects of confounding factors that are sometimes not evident.”

That suite of deficiencies is precisely the problem with the study and, for that matter, the several prior studies the researchers generously referred to as “accumulating evidence.”

Diabetes and metabolic syndrome are common conditions that are multifactorial in origin and, therefore, difficult to study through epidemiologic analysis. The researchers admitted that not all risk factors were considered. Overlooked, for example, was the confounding factor of genetics, a key risk factor for both type 2 diabetes and metabolic syndrome. Data on the study subjects’ genetics, such as family medical history, wasn’t collected and factored into the statistical analysis. Could this omission be important?

It is clear from the study analysis that the more confounding factors the researchers considered, the weaker their statistical correlations became. Had a more complete and thorough data collection and analysis been undertaken, it’s quite possible that even their weak correlations would have entirely evaporated.

Another glaring problem is that the researchers don’t really know how much diet soda any study subject consumed during the 8-year-long study. Instead, they relied only on study subject guesstimates of consumption made at the beginning of the study period.

While the study doesn’t appear to add anything meaningful to what we know about diet and health, it will no doubt add grist to the growing campaign against diet soda that was launched by a 2005 report, also from University of Texas researchers.

That study reported that diet soda drinkers were at greater risk of obesity than sugar-sweetened soda drinkers and concluded that artificial sweeteners “might be fueling — rather than fighting — our escalating obesity epidemic.” It was an awfully big conclusion to be drawn from a study where, among other deficiencies, the study subjects’ consumption of diet beverages was once again guesstimated, rather than verified or validated by the researchers.

But if a study has been published, it must be true, right?

In its January 2009 issue, the self-proclaimed “healthy lifestyle” magazine, Prevention, labeled diet soda a “health food impostor” and stated that, “Drinking just one can or bottle a day increases your risk of metabolic syndrome, which packs on heart-unhealthy belly fat. Sip flavored seltzer water instead. Steer clear of those sparkling waters that contain artificial sweeteners: they’re just diet soda in disguise.”

The Idaho-Statesman (Jan. 13) ran a column from the “YOU Docs”– Mike Roizen, M.D. and Mehmet Oz, M.D. — that warned readers, “See those people in the soda aisle? They all have something in common: a higher risk of heart disease. And you may be one of them, even if you drink only one 12-ounce soft drink daily — be it regular or diet.”

New York Governor David Paterson recently proposed to tax non-diet sodas based on dubious claims about their role in weight gain. It’s not too hard to figure out where the junk science railroad may be headed next.

New York Governor David Paterson has proposed to levy an 18 percent tax on non-diet soft drinks under the guise of combating obesity. Government doesn’t get much more cynical than this.

After alleging that “almost one in four New Yorkers under age 18 are obese,” Paterson’s budget proposal for 2009-2010 asserts that, “Significant price increases should discourage individuals, especially children and teenagers, from consumption and help fight obesity which results in higher risk for diabetes and heart disease.” So the purpose of the tax, according to proposal, is to discourage people from drinking non-diet soft drinks.

The proposal then estimates that the tax will raise $404 million during 2009-2010 and — get this — $539 million during 2010-2011. Since tax revenues from non-diet soft drink sales are budgeted to increase rather than decrease — as one might expect from the alleged purpose of the tax — Paterson actually seems to be counting on the tax not working. Combating obesity is not grounds for the tax; it is, instead, camouflage for it — and not very good camouflage at that.

In his Dec. 18 New York Times paean to the tax, columnist Nicholas Kristof ominously intoned that, “The average American consumes about 35 gallons of non-diet soda each year and gets more added sugar from soda than from desserts.”

But that 35 gallons works out to about a can of non-diet soda (containing about 140 calories) per day. Is a can of non-diet soda per day something to worry about? If common sense is not enough to answer that question, then consider the food recommendations made by the U.S. Department of Agriculture (USDA).

In its dietary guidelines for Americans — a.k.a. the “Food Pyramid” — the USDA recommends the servings that should be consumed daily from different food groups, including fruits, vegetables, grains, meats, milk and oils. The USDA makes these recommendations for different levels of individual daily calorie consumption, starting at a 1,000-calorie-per-day diet and going up to a 3,200 calorie-per-day diet.

In addition to fruits, vegetables, grains and the other food groups, the USDA also includes a category labeled, “Discretionary calorie allowance,” which constitutes the calories left over for each diet level after consuming the recommended amounts from the other food groups. Someone who should consume 1,000 calories per day and who ate the recommended portions of fruits, grains, meats, milk and oils would only have consumed 835 calories. That person would have 165 calories left over for discretionary eating — more than enough room for a 140-calorie can of non-diet soda. At the high-end of daily calorie consumption, someone who is on a 3,200-calorie-per-day diet would have a discretionary calorie allowance of 648 calories — more than 4.5 cans of non-diet soda.

The bottom line is that, all calories being equal, a can of non-diet soda per day — that is, Kristof’s ominous 35 gallons per year — is well with the guidelines of the USDA’s Food Pyramid for most people and so cannot be viewed as a persuasive factoid in support of Paterson’s proposed tax.

Kristof is also way off base in his effort to liken non-diet soft drinks to tobacco. “These days,” Kristof asserts, “sugary drinks are to American health roughly what tobacco was a generation ago.” Kristof then quotes long-time food nanny Barry Popkin, who says, “Soft drinks are linked to diabetes and obesity in the way that tobacco is to lung cancer.”

As this column has pointed out before, there simply is no scientific basis for concluding that non-diet drinks cause obesity or diabetes. The National Academy of Sciences concluded in 2002 that, “There is no clear and consistent association between increased intake of added sugars and [body weight].” And this remains true today.

An August 2008 review of research on soft drinks and weight gain by Emily Wolff (Boston University School of Medicine) and Michael Dansinger (Tufts University) concluded, “Sugar-sweetened soft drink intake has increased dramatically during the past few decades, yet the magnitude of the weight gain and adverse health effects by soft drinks are poorly understood due to a paucity of clinical trial data… which would be necessary to demonstrate a causal link between sugar-sweetened soft drink consumption and weight gain.” The translation is that despite decades of research — including at least five clinical trials — into the health effects of soft drinks, scientists still can’t identify any specific harm with any certainty.

Public health scolds unfortunately often try to blacken and intimidate anyone who disagrees with them by likening them to the tobacco industry. But to the extent there is any deceit-in-the-name-of-money being practiced in the case of non-diet drinks, that charge is more appropriately laid at the feet of the New York Governor and his supporters in the media and public health industry. If this group was sincere about its concern for obese children, it would do something other than just exploiting them as a means of raising money for the state.

The New York City Board of Health this week banned the use of trans fats by restaurants. The decision is directly traceable back to the “research” of Harvard University’s Alberto Ascherio and Walter Willett, the promoters-in-chief of trans fats hysteria.

Now that the Board has deemed their dubious trans fats research suitable for dictating public policy, New Yorkers ought to hope that Ascherio and Willett don’t press the Board to implement some of their other published research that is similar in “quality” to their trans fats work.

New Yorkers could, for example, see restaurants banned from serving potatoes, peas, peanuts, beans, lentils, orange juice and grapefruit juice. Ascherio-Willett reported an increase in the risk of heart disease among consumers of these foods in the Annals of Internal Medicine (June 2001). Although none of those slight correlations were statistically meaningful — and, in all probability, were simply meaningless chance occurrences — a similar shortcoming didn’t seem to matter to the Board when it came to their trans fats research.

Indian restaurants could be banned from cooking with sunflower oil. Ascherio-Willett once found that consumers of Indian food cooked in sunflower oil were up to 3 times more likely to suffer heart attacks than consumers of Indian food cooked in mustard oil (American Journal of Clinical Nutrition, April 2004).

Sure it was only one study and even they acknowledged the need for more research — but that didn’t stop Ascherio-Willett from recommending the switch in cooking oils.

Red meat might disappear, too.

Ascherio-Willett reported a 63 percent increase in the risk of type 2 diabetes associated with iron intake from red meat (American Journal of Clinical Nutrition, Jan. 2004). They didn’t bother to verify how much iron from red meat any of the study subjects consumed and, therefore, don’t actually have a firm basis for linking red meat consumption with the disease – but what the heck, they don’t really know the quantity of trans fats consumed by any of those study subjects either.

It’s not looking good for dairy products either. Ascherio-Willett reported in the Annals of Neurology (Dec. 2002) that consumption of dairy products was associated with an 80 percent increase in the risk of Parkinson’s Disease among men. Although they concluded at the time that the finding needed further evaluation, why should the Board wait for more research? That could take forever. If the inconsistent and contradictory trans fats research doesn’t require further evaluation, I can’t imagine why it would be necessary for dairy products.

Regular (sugar-sweetened) soft drinks ought to be history as well. Willett linked them with weight gain and diabetes in women (Journal of the American Medical Association, Aug. 25, 2004). It didn’t even matter that the same study also inexplicably linked diet soft drinks with a similar risk of diabetes.

It’s really odd that when their research inadvertently debunks itself and other food myths, almost no one learns of it. And that’s true for their trans fats research, as well.

The Board’s notice of its decision to ban trans fats tries to bolster its case by playing on popular misconceptions about saturated fat. The notice states that, “trans fat appears even worse than saturated fat.” The Board apparently isn’t familiar with the several Ascherio-Willett studies that fail to link saturated fat with heart disease and stroke.

The public’s 30-year long fear of saturated fat and the Board’s statement is, in fact, without a scientific basis. It’s simply astounding that the Board can get away with exploiting one debunked myth to help propagate another.

Just to show that not all the Ascherio-Willett research is about simply banning foods – after all, it is possible that at some point the public will tire of being nannied – the Board may want to consider requiring restaurant patrons to order caffeinated coffee with every meal. One Ascherio-Willett study reported that the risk of type 2 diabetes was reduced by a statistically significant 54 percent among men who consumed 6 or more cups of coffee per day (Annals of Internal Medicine, Jan. 6, 2004).

The Board might also want to mandate the daily consumption of pizza by men. Ascherio-Willett reported that men who consume more than 10 servings of pizza per week reduce their risk of prostate cancer by one-third (Journal of the National Cancer Institute, Dec. 1995).

It’s not that either coffee or pizza is a proven “health” food – far from it – but the Board should consider their great distraction potential. Just as the ancient Roman emperors distracted citizens with bread and circuses while taking away their freedoms, the Board could easily distract New Yorkers with coffee and pizza as it dismantles consumer choice in restaurants bit by bit.

Come to think of it, why is the Board’s trans fats ban limited to restaurants? What about grocery stores and convenience shops? If trans fats are so bad, why should you be able to purchase food in a store that is too dangerous to be served in a restaurant?

The Board’s trans fats ban has dramatically lowered the bar for scientific proof. It’s such a sad spectacle that the Board of Health ought to be renamed the Bored of Science.
