Outsmarting the enemy


"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 was reminded of a story after reading your blog today.   I can't verify the story but it's wise nevertheless.  A baseball fan encountered one of the all time greats and Hall of Famer, Stan Musial.  Fit and trim throughout his life, the fan asked him, long after his baseball career was over, how he maintained his weight.  He replied, "I exercise everyday."  Still curious, the fan inquired further, "What exercises do you do."  Musial replied: "I push myself away from the table."  Many of us could learn from that simple wisdom, myself included.  Keep on blogging Dr. Davis, it helps us stay "mindful."

    Terry,

    Not sure how seriously your comment was intended, but it misses the boat.  It's the TYPES of food we eat that are killing us.  Smaller quantities of Reduced Fat Bacon Toaster Scrambles and AHA "Heart Healthy" Count Chocula won't save us.  See Eat To Live by Joel Fuhrman, along with Dr. Davis' own remarks on this.

Paging Dr. Basedow

Paging Dr. Basedow

A 23-year old man came to my office having experienced weeks of extreme anxiety, palpitations, and 19 pounds of weight loss triggered by an overactive thyroid.

It all happened because of a large dose of iodine received during a CT scan using iodine-containing x-ray dye. (X-ray dyes are made visible on x-ray due to the iodine content.) This is a reaction first described in the 19th century by German physician, Karl Adolph von Basedow. (Jod is German for iodine.)[caption id="attachment_4313" align="alignleft" width="217" caption="Dr. von Basedow. Image courtesy Wikipedia"][/caption]

Now, here's the kicker: Jod-Basedow only occurs when there is pre-existing iodine deficiency. Indeed, this young man had an enlarged thyroid, signaling longstanding iodine deficiency (a goiter).

This example is among the more flagrant examples of something I have been witnessing: the return of iodine deficiency. As Americans cut back on their intake of iodized salt and fail to obtain iodine in sufficient quantities from seafood, seaweed, or supplementation, goiters and iodine deficiency are making a return in all its glory, reminiscent of the early 20th century, pre-iodized salt.

This young man's frightening experience is yet another way iodine deficiency can show itself, by the overenthusiastic thyroid response to a large dose of iodine when iodine deficiency has been present for a prolonged period.

Iodine deficiency and goiters have been lost to memory for most people. Even the FDA, in its advice for Americans to reduce salt and sodium intake, have forgotten to remind everyone to obtain iodine from an alternative source. "Those who cannot remember the past are condemned to repeat it."

Get your iodine.

    1 gram of Dulse sea weed (Maine coast waters a common clean source)  = 110% daily value of iodine; dulse tastes very pleasant raw  or pan roasted (not burnt black) as a garnish; 1 gram of bulked up dulse (not pulverized into powder) is less than 1/20th  of a cup's volume.

    There is a fascinating article about the imprtance of Omega 6.
    Yes, Omega 6, not Omega 3.
    We might have overblown the importance of Omega 3.

    If iodine supplimentation is needed, what is the recommended dosage?  Not FDA, but in your opinion!

    Hi, Lisa--

    We've been using 500-1000 mcg with success.

    Fats relationship to HOMA-R (homeostasis model insulin resistance index) means a postive  (+) HOMA-R worsens insulin resistance.  Here is a breakdown of this relative to individual poly unsaturated fatty acids (PUFA) from Japan research (2007?).

    PUFAs with a + HOMA-R:
    eicosadienoic (C 20:2 chain) omega 6
    dihomoylinolenic (C 20:3 chain) omega 6
    docosapentaenoic (C 20:5 chain) omega 3
    docasatetraenoic (C 22:4 chain) omega 6

    PUFAs with no relationship to HOMA-R:
    linolenic (C 18:2 chain) omega 6
    arachidonic (C 20:4 chain) omega 6
    eicosapentaenoic ( C 20:5 chain) omega 3 (EPA)
    docosahexaenoic (C 22:6 chain) omega 3 (DHA)
    eicosatrienoic (C 20:3) omega 9

    Mighto:
    so what are dietary recommendations for balancing Omega3 / Omega6 ?
    What foods/fats can we eat, what foods/fats should we avoid?
