Consider that for the last year or so, we have been treated a deluge of entreaties to reduce our salt intake, with the American Heart Association going so far as to claim that daily sodium intake should not exceed 1,500 mg. This puts it at odds with the Institute of Medicine, and now European researchers whose data indicates that the healthy range for sodium intake appears to be much higher.
Our conversation about sodium, much like advice about purportedly evil saturated fats and supposedly beneficial polyunsaturated fats, exemplifies a national obsession with believing eating more or less of a one or a small number of nutrients is the path to nutritional nirvana.
A few weeks back, an international team of scientists did their level best to feed this sensationalistic beast by producing what’s become known since then as the meat-and-cheese study, because it damned consumption of animal proteins.

The Affordable Care Act might not bend the cost curve or improve the quality of health care, but it will save thousands of lives, as millions of uninsured persons receive the health care they need.
At least that’s the conventional wisdom.
But while observers assume that ACA will improve the health of the uninsured, the link between health insurance and health is not as clear as one may think. Partly because other factors have a bigger impact on health than does health care and partly because the uninsured can rely on the health care safety net, ACA’s impact on the health of the previously uninsured may be less than expected.
To be sure, the insured are healthier than the uninsured. According to one study, the uninsured have a mortality rate 40% higher than that of the insured. However, there are other differences between the insured and the uninsured besides their insurance status, including education, wealth, and other measures of socioeconomic status.
How much does health insurance improve the health of the uninsured? The empirical literature sends a mixed message. On one hand is an important Medicaid study. Researchers compared three states that had expanded their Medicaid programs to include childless adults with neighboring states that were similar demographically but had not undertaken similar expansions of their Medicaid programs.
In the aggregate, the states with the expansions saw significant reductions in mortality rates compared to the neighboring states.
On the other hand is another important Medicaid study. After Oregon added a limited number of slots to its Medicaid program and assigned the new slots by lottery, it effectively created a randomized controlled study of the benefits of Medicaid coverage. When researchers analyzed data from the first two years of the expansion, they found that the coverage resulted in greater utilization of the health care system.
However, coverage did not lead to a reduction in levels of hypertension, high cholesterol or diabetes.

I love interactive data visualization (#dataviz). It is one of the things that I definitely wanted to explore when I came out to the Bay Area on sabbatical, because I believe that it has great potential for helping both patients and clinicians with diabetes management. The sheer volume of numbers available for this disease is overwhelming; we need #dataviz tools that can help us achieve greater understanding and make actionable clinical decisions to improve health.
This is what we usually see in clinic: numbers written down on a piece of paper.
Yes there are computer systems that link to blood glucose meters, but there are a number of complexities with the downloading of blood sugar numbers in clinic (which deserves an entire blog post sometime in the future).
You can see there is some visual analysis and annotation that we do perform, albeit primitive. The circles represent high blood sugars (>150 mg/dl)and the triangles represent low blood sugars (<70 mg/dl). This is almost better than the cave painters don’t you think?
But even the minority of patients who download their BS to the computer, are viewing dashboards like this.
Pie charts, need I say more? I can extract some useful insights from these charts, which improve over the previous one I showed, but a few things strike me: (1) some of the scatter plots overlay weeks of data, which I don’t find helpful because you can’t tell how BS on a given day are responding and relate them to life events; (2) some visualizations show a lot of numbers in many of the sections, and it just becomes onerous to go through them and find trends; (3) many provide statistics (area under the curve, MAD%) which I think only a minority of families and children really understand; (4) although some of the software programs do provide interactivity and let you see the data at different time scales (day, week, month), if you change to a different view, you are stuck trying to remember in your head what you saw on a previous screen because you can’t see the multiple levels at once; (4) finally, I find that the user interface and design could use major improvement.

As we look back over the past year and some of the amazing medical breakthroughs like wearable robotic devices, genomic sequencing and treatments like renal denervation that are improving people’s lives, it bears reflection on what else we could be doing better. Our world has changed more in the past century than in thousands of years of human history. We not only know more about our biology than ever before, but science and technology are unlocking the secrets of the very building blocks of our health. Somehow, in the midst of this incredible innovation, we’ve gotten fat, and not just a little. The result? Alarming rates of obesity and related chronic disease that threaten to crush us physically and financially.
But is it technology’s fault that we’ve become fat? A recent study by the Milken Institute that tied the amount an industrialized country spends on information and communication technologies directly to the obesity rates of its populations thinks so.
Most of us are guilty of a little overindulgence around the holidays but for many, overindulgence is a normal way of life. As economies transition to more sedentary, the physical movement that burned calories and kept us fit simply does not occur. Our lifestyles compound the issue — dual-income homes rely on the convenience of packaged meals, and our leisure activities have shifted to heavy “screen time” with movies, games and social media.

My job and my life intersected in a profound way when my daughter was diagnosed with Type I diabetes. Years working in mobile innovation didn’t prepare me for how personally relevant mHealth so quickly became. Her clinical trial at Stanford University, supported by the National Institutes of Health through Congress’ Special Diabetes Program, featured a world-class endocrinologist working alongside software coders, applications developers, algorithm writers, network engineers and other mobile innovators. They were all pushing together for what could be a revolution in diabetes management—the artificial pancreas.
Recently I had the opportunity to talk about my daughter’s experience and share my thoughts on how government can help encourage the next wave of mHealth innovation, when I was invited to testify before Congress on mobile innovation and health care.
America’s leadership in the mobile economy — 40,000 apps and counting in the broad mHealth category — matches America’s leadership at the cutting edge of medical technology.
Mobile devices, wireless networks and targeted applications are enabling better, more seamless and cost-effective care that empowers and informs stakeholders on both sides of the stethoscope.
The virtuous cycle of investment in the mobile ecosystem — from networks, to handsets and tablets, to applications — provides an unparalleled foundation for dramatic advances in the nation’s health and wellness. My message to Congress was to lean in and strike a reasonable and circumspect balance that both protects patient safety and privacy and propels the dramatic, mobile-fueled advances we are seeing through American medicine today.

Can the FDA ban cupcakes?
While this may seem like a silly question, the Center for Science in the Public Interest (“CSPI”) has filed a petition with the FDA urging the agency to regulate the amount of sugar (including high fructose corn syrup) in soft drinks. According to the executive director of CSPI, sugar is a “slow-acting but ruthlessly efficient bioweapon” that causes “obesity, diabetes, and heart disease.”
If soft drinks are a problem, surely cupcakes are too. A twelve-ounce can of Coca-Cola contains 39 grams of sugar. A seasonally-appropriate red velvet cupcake from Sprinkles contains 45 grams of sugar—and who can eat just one? National cupcake consumption increased 52% between 2010 and 2011, and U.S. consumers ate over 770 million cupcakes last year. Sugary soft drink consumption, on the other hand, is down 23% since 1998 and 37% since 2000.
While the FDA can’t regulate sugar as a bioweapon, it probably could regulate sugar as a food additive.
Under the Food, Drug, and Cosmetic Act, a food additive is “any substance the intended use of which results or may reasonably be expected to result—directly or indirectly—in its becoming a component or otherwise affecting the characteristics of any food.” This broad definition would include sugar. The FDA does not, however, regulate food additives that are “generally recognized as safe” (“GRAS”). Presumably the FDA considers sugar to be GRAS—for now. Continue reading “Let Them Eat Cupcakes”

According to a widely circulated op-ed in the New York Times by Paul Campos, a law professor at the University of Colorado with whom I don’t believe I have ever managed to agree on anything, our “fear” of fat — namely, epidemic obesity — is, in a word, absurd. Prof. Campos is the author of a book entitled The Obesity Myth, and has established something of a cottage industry for some time contending that the fuss we make about epidemic obesity is all some government-manufactured conspiracy theory, or a confabulation serving the interests of the weight-loss-pharmaceutical complex.
In this instance, the op-ed was reacting to a meta-analysis, published last week in JAMA, and itself the subject of extensive media attention, indicating that mortality rates go up as obesity gets severe, but that mild obesity and overweight are actually associated with lower overall mortality than so-called “healthy” weight. This study — debunked for important deficiencies by many leading scientists around the country, and with important limitations acknowledged by its own authors — was treated by Prof. Campos as if a third tablet on the summit of Mount Sinai.
We’ll get into the details of the meta-anlysis shortly, but first I’d like to say: Treating science like a ping-pong ball is what’s absurd, and what scares the hell out of me. Treating any one study as if its findings annihilate the gradual, hard-earned accumulation of evidence over decades is absurd, and scares the hell out of me. Iconoclasts who get lots of attention just by refuting the conventional wisdom, and who are occasionally and importantly right, but far more often wrong — are often rather absurd, and scare the hell out of me.
And so does the obesity epidemic.

Henry David Thoreau said, “There are a thousand hacking at the branches of evil to one who is striking at the root.”
We have hacked at healthcare costs for what seems like thousands of times, with very limited success. It is time to strike at the root. Rather than focus on reducing costs after preventable diseases have taken hold, it is time to focus attention on eliminating the disease.
Let us look at two specific examples.
1. The CDC (Center for Disease Control and Prevention) has estimated that the cost of smoking(estimated cost of smoking-related medical expenses and loss of productivity) exceeds $167 billion annually. The CDC has also estimated that 326 billion cigarettes (combustible tobacco, to be more precise) went up in smoke in 2011. In other words, every cigarette consumed costs the nation about 50 cents; every pack, $10.
Put another way, while the smoker paid approximately $5 a pack up front, there was also an additional $10 secret surcharge — the cost of which is born by all of us (such as taxpayers, anyone who buys health insurance, even private companies who suffer from lower productivity as a result). It is as if we are telling the smoker, “I know you can’t afford to pay $15 for a pack. So we will give you $10 so you can afford to smoke.” We are not this generous even with people who don’t have one square meal a day. We spent $78 billion on food stamps, with constant pressure to bring that down further even if some people will be left without food as a result.

Twenty years ago, in order to keep presidential candidate Bill Clinton’s campaign on message, James Carville hung a sign in their “war room” that read:
- Change vs. more of the same
- The economy, stupid
- Don’t forget health care
While point number two swiftly entered the national vernacular, the other two slogans have equally influenced the U.S. political landscape, especially since 2008. Four years ago, the country was on the precipice of transformation. Meaningful change was promised, and opportunities for significant, long-lasting reforms were abundant. Americans, particularly the millennial generation, turned out in record numbers to vote, and hope for the future was palpable. America, like a patient suffering from a debilitating chronic disease, seemed finally ready to put in the time and do the hard work to get healthy before that fatal heart attack occurred. After decades of procrastination, we heeded Carville and health care system overhaul became a top priority.
Pause: The State of America’s Health
Obesity prevalence increased 137 percent over 20 years, from 11.6 percent to 27.5 percent of the population. In 2008, more than one-third of children and adolescents were overweight or obese. The medical care costs of obesity in the U.S. totaled about $147 billion in 2008 dollars.
Diabetes has almost doubled in prevalence since 1996, rising from 4.4 percent to 8.7 percent of the adult population. For children, the prevalence of Type 2 diabetes increased 21 percent from 2001-2009, while Type 1 diabetes rose 23 percent. Estimated total diabetes costs in the U.S. were $174 billion in 2007.
Asthma diagnoses grew by 4.3 million from 2001 to 2009, and 9.4 percent of children currently have asthma. Asthma costs in the U.S. grew from about $53 billion in 2002 to about $56 billion in 2007.
Developmental Disabilities prevalence increased 17.1 percent over the last 12 years. The prevalence of autism increased 289.5 percent, and the prevalence of ADHD increased 33 percent. Autism alone is estimated to cost the U.S. $137 billion per year.

If all of us were simply to make better use of our feet, our forks, and our fingers — if we were to be physically active every day, eat a nearly optimal diet, and avoid tobacco — fully 80 percent of the chronic disease burden that plagues modern society could be eliminated. Really.
Better use of feet, forks, and fingers — and just that — could reduce our personal lifetime risk for heart disease, cancer, stroke, serious respiratory disease, or diabetes by roughly 80 percent. The same behaviors could slash both the human and financial costs of chronic disease, which are putting our children’s futures and the fate of our nation in jeopardy. Feet, forks, and fingers don’t just represent behaviors we have the means to control; they represent control we have the means to exert over the behavior of our genes themselves.
Feet, forks, and fingers could reshape our personal medical destinies, and modern public health, dramatically, for the better. We have known this for decades. So why doesn’t it happen?
Because a lot stands in the way. For starters, there’s 6 million years of evolutionary biology. Throughout all of human history and before, calories were relatively scarce and hard to get, and physical activity — in the form of survival — was unavoidable. Only in the modern era have we devised a world in which physical activity is scarce and hard to get and calories are unavoidable. We are adapted to the former, and have no native defenses against the latter.
Then, there’s roughly 12,000 years of human civilization. Since the dawn of agriculture, we have been applying our large Homo sapien brains and ingenuity to the challenges of making our food supply ever more bountiful, stable, and palatable; and the demands on our muscles ever less. With the advent of modern agricultural methods and labor-saving technologies of every conception, we have succeeded beyond our wildest imaginings.
So now, we are victims of our own success. Obesity and related chronic diseases might well be called “SExS” — the “syndrome of excessive successes.”
