l papers on the future of scanning, where I would read the paper in the darkened hall until lunchtime and then head off for some hot Hunan and home.
Instead, the place was like a carnival for cardiologists.
Kessler has, in Silicon Valley style, left a wide wake of electronic content to get a better view of his ideas. There is a podcast located on the InstaPundit site that you can listen to at: http://podcasts.instapundit.com/AndyKessler.mp3, that provides some more of this irreverent but out-of-the-box thinker's thoughts.
For anyone looking for a discussion about the emerging role of vitamin D as a cause for coronary disease, see my recent article, Vitamin D’s Crucial Role in Cardiovascular Protection, in Life Extension Magazine, now posted online at:
Vitamin D has assumed an absolutely critical role in the Track Your Plaque program for coronary plaque reversal and dropping CT heart scan scores. Since adding vitamin D and aiming for blood levels of 50-60 ng/ml, our success rate has skyrocketed. In fact, I wonder just how well our two most recent record holders--51% and 63% drops in heart scan scores--would have fared without it. (They probably would have dropped, but no where near as much.)
Also, a full-length booklet that contains just about everything you want to know about vitamin D (or at least a right-this-moment summary of what is known about it) will be available to Track Your Plaque Members for free before the end of the year.
Brian Wansink, author of Mindless Eating: Why we eat more than we think (see yesterday's Heart Scan Blog post), also has a Blog. Despite the bland advice offered on much of the Prevention Magazine and website, Wansink's Food Think Blog is a winner.
In a recent post, Wansink quotes a report from Science Daily that described a study he recently published in the Journal of Consumer Research. Wansink's study describes how just applying the label "healthy" to fast food choices increased consumers' calorie intake:
"When we see a fast-food restaurant like Subway advertising its low-calorie sandwiches, we think, 'It's OK: I can eat a sandwich there and then have a high-calorie dessert,' when, in fact, some Subway sandwiches contain more calories than a Big Mac."
In one study, Chandon and Wansink had consumers guess how many calories are in sandwiches from two restaurants. They estimated that sandwiches contain 35% fewer calories when they come from restaurants claiming to be healthy than when they are from restaurants not making this claim.
The result of this calorie underestimation? Consumers then chose beverages, side dishes, and desserts containing up to 131% more calories when the main course was positioned as "healthy" compared to when it was not--even though, in the study, the "healthy" main course already contained 50% more calories than the "unhealthy" one.
"These studies help explain why the success of fast-food restaurants serving lower-calorie foods has not led to the expected reduction in total calorie intake and in obesity rates," the authors write.
Interesting. In fact, I've had many patients say that they eat at Subway or similar chains and choose the "healthy" options. "That's got to be better than a cheeseburger and fries!" Perhaps not. (Of course, you can't leave Subway or other fast food operation feasting on wheat products.)
Wansink can be counted on for some truly fascinating observations into many behaviors that are subconscious but explain at least part of the reason why we're so fat. Though his Blog has a relatively short history of posts, there's lots of great commentary.
Pierre Chandon and Brian Wansink. "The Biasing Health Halos of Fast Food Restaurant Health Claims: Lower Calorie Estimates and Higher Side-Dish Consumption Intentions" Journal of Consumer Research, October 2007.
"Everyone--every single one of us--eats how much we eat largely because of what's around us. We overeat not because of hunger but because of family and friends, packages and plates, names and numbers, labels and lights, colors and candles, shapes and smells, distractions and distances, cupboards and containers. This list is almost as endless as it's invisible.
Invisible?
Most of us are blissfully unaware of what influences how much we eat . . . We all think we're too smart to be tricked by packages, lighting, or plates. We might acknowledge that others could be tricked, but not us. That is what makes mindless eating so dangerous. We are almost never aware that it is happening to us."
So opens Brian Wansink's book, Mindless Eating: Why we eat more than we think.
Wansink studies consumer behavior at Cornell University. He's the guy who scrutinizes in excruciating detail why we eat what we do, what factors determine what we eat like food color and smell, the company we keep, product packaging. He works without food industry funding, though there are plenty of researchers who do this sort of research funded by the likes of Kraft, Nabisco, and Kellogg's.
His book is packed full of the conclusions he and his team have come to over the years studying our buying and eating habits. While this information could (and is) be easily used by the food industry to coerce us to eat more and more, understanding many of the concepts Wansink talks about can also open your eyes to their clever tactics.
He especially details how our internal satiety signals fail us when external cues are present that easily trip us up. He talks about one experiment he ran in which soup bowls were rigged with concealed rubber tubes in the bottom that continually replenished the soup as the person consumed it. Thus, with the bowl continually refilled, the eater had no idea how much he or she had consumed. When the quantity of soup eaten from the endless bowl was compared to people eating from standard bowls, there was as much as a three-fold increase in the quantity and calories eaten.
Just be aware that, while Wansink is an expert in consumer eating behavior, he is not necessarily an expert in nutrition. Just as a card shark can show you lots of clever tricks to hoodwink your opponent, he might not be the best person to teach you how to play bridge.
For a great hint at some of the interesting and all-too-human observations Wansink makes, the online Prevention Magazine posted a brief video:
We might not be able to stop Big Food from selling garbage foods, but we can at least be armed with insight into how we are subconsciously coerced into eating more.

I personally hate these stories, the ones that turn heart scans into drama by describing how someone had a heart scan, then turned out to have so much coronary plaque that they had to have bypass surgery.
But I point this one out because the story is related in an interesting way. It highlights the utter ignorance that operates in heart disease detection.
The story highlights how a 50-year-old, 5 ft 8, 150 lb slender, exercising neurologist underwent a CT coronary angiogram in a newly installed device in a Hartford, Connecticut hospital (not a heart scan) that detected entirely unsuspected severe and diffuse coronary disease. You know the rest: abnormal stress test, heart catheterization, bypass surgery of the hapless doctor-now-patient, followed by grateful patient saying things like "This machine saved my life."
It probably is true. You've seen these stories before. I've witnessed these sorts of headline-makers for the past decade. I remain surprised that it still happens.
The doctor is not some ignorant, uninformed man who can't even fill out his income tax forms. Yet how does a man like this walk around with life-threatening disease and not know it? Why does it still make headlines?
Anyway, despite all my jawing about heart scans and early heart disease detection, many physicians and the public remain in the stone age of heart disease. Even though this neurologist's story made headlines, the many other people who 1) identified their heart disease earlier with a simple heart scan, then 2) took action to put a stop to it, do not make headlines. But that's the way to go.
Why isn't the rest of the story being told? Why was this man's heart disease uncovered only in its late phases? Hartford, Connecticut is not some backwater. I've been there. It's a major city with large hospitals and a University Medical Center. But a professional with presumed knowledge of health and his doctor(s) allowed this to happen?
In other words, this is not a story of success, but of failure--failure to identify coronary disease years earlier when preventive action would have prevented bypass. But that's not such a compelling headline, is it?
As an aside, I'll bet you that this man has lipoprotein(a), a severe small LDL pattern, and severe deficiency of vitamin D. Correct these and it's unlikely he'll need bypass again. But that's kind of boring, isn't it?
I'd forgotten what a powerful report Peter Jennings and ABC News produced about the enormous deception perpetrated by the food industry and its effects on health until Dr. Joe Mercola posted the YouTube clips from the report on Mercola.com.
(This is not meant to be an endorsement of everything Dr. Mercola has to say. He says lots of things; I agree with only a fraction of it. But this is a gem.)
Although made in 2004, the report remains every bit as relevant today as it was then. It concerns me deeply that, despite reports like this being broadcast to Americans, the obesity epidemic continues unabated. In fact, it's worse just in the short three years since then.
Be aware of what the food industry is up to. They intensively market high profit margin foods to us--and especially our children--to increase sales. As Jennings points out, the U.S. government (USDA) is, for a variety of reasons both good and bad, complicit with this massive deception. While many media reports continue to focus on lack of exercise as the root cause for the obesity epidemic, it is really the active and purposeful selling of processed junk foods to Americans that is principally to blame.
By the way, how many of these foods proudly boast the American Heart Association Check Mark of approval?
