Jamba Juice - More Calories than a Footlong Meatball Sub!

It's possible that fruit and vegetables are the easiest products in the world to market as healthy.

Everyone and his mother, this blog included, touts the health benefits of fruit and vegetable consumption.

That said, there's a world of difference between eating fruit and drinking it, and part of that world is calories.

Jamba Juice, a rapidly growing fruit smoothie franchise is a case in point.

On their website, they blindly stick to the low fat message and extol the virtue of carbohydrates,

"You can see that fat on a weight basis yields more than twice the energy per gram compared to carbohydrates and proteins. But since the body uses carbohydrates for energy, and carbohydrate foods also provide other nutrients, you should try to meet your energy needs with carbohydrates rather than fats."
So how much energy are we talking about at Jamba Juice?

Insane amounts!

If you were to drink their "Power" version of virtually any of their products, you're drinking more calories than a Big Mac.

If you were to choose unwisely (with unwise here not really referring to calories, but rather to a choice that you felt was a healthy one because it was Jamba Juice after all), and had their Power Peanut Butter Moo'd, which as described by the Jamba Juice website is,
"Made with all-natural peanut butter, this super-smoothie is chock full of good stuff and tastes great too."
and then you looked at the ingredients,
"nonfat frozen yogurt, chocolate moo’d base, soymilk, ice, frozen bananas, all-natural peanut butter"
and thought, gee, that seems healthy, I'll have that, wanna know what you'd be having?

1170 Calories! The equivalent of 2 Big Macs, a foot long meatball marinara sub, a 1.5lb T-Bone steak or almost a full cup of peanut butter.

Yummy?

So why did I go off on this Jamba Juice rant? Well for Funny Friday of course.

Here's Natalie Portman in one of the best skits I've seen on SNL in years, making fun of the added health benefits of the "boosts" of Jamba Juice.

Have a great weekend and happy New Year!

Why Does Universal Studios care more about you than Health Canada?

Well, maybe that's just blogger license to get you to read, but as of this Christmas Eve, Universal Studios Hollywood is trans-fat free.

Trans-fats, as covered in one of my prior posts, aren't very good for you. Trans fats have been shown to raise bad cholesterol, raise triglycerides, lower good cholesterol and make our blood stickier increasing the risk of blood clots. Trans fats have also been shown to increase the process of inflammation in our body which in turn has been implicated in heart disease and diabetes and may well also be involved in other disease processes.

Amazingly in Canada despite the wealth of knowledge on the risks of trans-fats, despite the June 2006 final report of Health Canada's trans-fat task force calling for a dramatic regulatory minimization of trans-fat in our food supply, it appears to this outsider at least, that Health Canada has spent the last 6 months apparently doing nothing to try to put their recommendations into action (no doubt much to the joy of the Canadian Restaurants and Food Services Association and the Food and Consumer Products of Canada Association - Merry Christmas Big Food, Love, Health Canada).

The thing is, we're talking about a product which without tremendous upheaval (Denmark has been trans-fat free since December 2003) can indeed be removed from the food supply. If applied to North America, according to the Center for Science in the Public interest, a trans-fat ban could save 11,000-30,000 lives per year along with $50 billion in annual health care costs.

I suppose given my experiences with Health Canada and Canada's Food Guide, I shouldn't be too surprised - remember, Health Canada didn't even bother to mention the words trans-fats in the draft of their upcoming new Food Guide.

Sometimes I wish I lived in Denmark.

Kudos to Universal Studios.

Weight Loss Decreases your Risk of Aggressive Prostate Cancer

This month's Cancer Epidemiology Biomarkers and Prevention journal has a fascinating study on the effect of weight loss on the development of prostate cancer (Full-text free here).

Author Carmen Rodriguez and colleagues were curious to see whether or not weight loss affected the risk of prostate cancer.

Seven of nine prior prospective studies had demonstrated that increased weight was associated not with increased risks of prostate cancer overall, but rather increased risk of aggressive prostate cancer and prostate cancer mortality.

The study population started with the 86,404 male participants of the Cancer Prevention Study II Nutrition Cohort followed by the American Cancer Society since 1992.

In a methodology too rarely seen in weight loss studies, the authors chose to exclude the first 2 years of followup (1992-1994) for their 11 year study due to the fact that many diseases lead to weight loss, and should initial weight loss be unintentional and due to an as yet diagnosed serious illness, the results from those individuals would negatively skew the results of the study. This type of lead-in bias in studies including weight as a variable has certainly tainted the results of the many of them that did not include a first-few years weight loss exclusion criteria.

The results were rather striking.

Firstly the risk of low-grade (less aggressive) prostate cancer actually decreased significantly with increasing weight! In contrast however, the risk of high grade (more aggressive) prostate increased with increasing weight, as did the risk of metastatic spread from the prostate and prostate cancer mortality.

(For the authors comments as to some possible biological explanations for these trends, read their clear discussion in their paper)

In terms of weight loss, men who lost 11 or more pounds between 1982 and 1992 had a 40% lower risk of developing aggressive prostate cancer!

That weight increases your risk of developing cancer has certainly been established beyond any significant shadows of doubt in multiple prior studies. What's so exciting about this study is that it's now the second study that has specifically identified intentional weight loss as a means to decrease your risk of cancer (the first demonstrating that women who lost 22lbs had a 60% decrease in their risk of developing breast cancer, published in 2006 in JAMA).

11 pounds is certainly not 100!

Truly even small amounts of weight loss can lead to dramatic affects on your health.

Children's Fitness Tax Credit for Rich Canadians

Last week Jim Flaherty, the Minister of Finance, released the guidelines for the Children's Fitness Tax Credit.

If you want to use it, it's sure as heck gonna cost ya.

In order to qualify you'll have to enroll your child in an ongoing supervised program that,

"includes a significant amount of physical activity that contributes to cardio-respiratory endurance, plus one or more of: Muscular strength, muscular endurance, flexibility, and balance."
But wait, there's more! Eligible programs must,
"last at least eight weeks at a minimum of one session per week"
That sure sounds like one hell of an expensive tax credit as it's not as if the credit's going to cover the costs of these programs in their entirety!

What about the Canadians who can't afford to send their children to organized programs?

What about the Canadians who might live in the country where the availablity of such programs is minimal?

What about the Canadians whose kids don't happen to enjoy organized sports?

What about the Canadians who are too busy trying to put food on their tables to drive their kids around to sports, let alone outfitting them in gear and paying for their supervision?

Does the government really think that a small tax credit is actually going to enable families who otherwise can't afford to send or outfit their children for organized sports to actually do so?

Why can't the tax credit be applied to anything that might promote physical activity in children?

What about the purchase of skates? A family might not be able to afford to send their kid to play competitive hockey, but a pair of skates and a local rink sure can afford a kid a great deal of exercise.

What about running shoes, a sled, roller blades, a baseball glove, a football or a basketball net?

Why does play have to be organized and supervised in order to be valuable as a determinant of health?

It may surprise you to learn that over the course of the last seven years, Canada has posted a budget surplus of over $60 billion, and it's predicted that there will be similar surpluses over the next seven years.

Why not use some of it to help all of our children become more active, not just the rich ones?

CLA - Far from a Magic Weight Loss Bullet

The media are alive with the sound of CLA!

I can't get over the number of articles I've read, in both mainstream and blogosphere press, about the benefits of supplementation with CLA (conjugated linoleic acid) on body weight and body fat percentage, and all from a very small, limited, and poorly designed study.

The study took 40 (yes, just 40) people and randomly assigned 20 to receive a CLA supplement and 20 to a placebo for a 6 month period. The subjects were exclusively young (between the ages of 18 and 44) and none of them were obese to begin with (BMI between 25 and 30). They were watched to see if there was a difference in weight loss and/or a difference in their body fat percentage.

The study was written in a manner that was supposed to reflect "holiday weight gain" by being conducted over the course of last year's Christmas holiday season. That said, while the study participants were indeed controlled so that the placebo and control groups were roughly the same age and weight, what was not controlled for was lifestyle.

What do I mean by that? Well, there's no note about whether or not the participants used gyms, whether or not they had sedentary or active jobs and importantly, given the aim to discuss "Holiday" weight gain, their religions, whether or not they had large family gatherings over the holiday season and whether or not they themselves celebrated a holiday season were not mentioned in the methodology or controls.

Regardless, even if we ignore the clear lack of appropriate controls, the results were far from spectacular.

With a percentage just barely greater than would happen by chance, the folks in the CLA group lost a grand total of 1.3lbs and their body fat percentage went down by 1%.

So what can we conclude from this paper?

Not too much.

Best case conclusion:

If you're a non-obese, young adult and you want to spend over $20 a month on CLA supplements, you may lose 1.3lbs over a 6 month period.
Woo-hoo?

Wanna know how else you could lose 1.3lbs over a 6 month period?

Burn or not eat 25 calories a day.

Hmmm, let's see, $120 in pills that may have long term risk (in multiple studies CLA has been shown to increase insulin resistance and increase deposition of fat in the liver and spleen) or you could simply walk for an extra 5 minutes every day.

As I tell all my patients, if there was something that I could sell them that would help them lose weight and help me pay the rent, I would.

Guess I'm the scrooge of supplements 'cause I don't sell any!

Merry Christmas to all those celebrating, and a big Bah-Humbug to the neutraceutical corporations and the press who get folks excited about non-exciting stuff!

The Creepiest Fast Food Mascots Ever!

Today for Funny Friday, a blast from the past.

The creepiest fast food mascots ever envisioned.

Watching the commercials I wonder two things: Firstly, how high were the folks who came up with these spots and secondly how is it possible that the folks over at Quiznos signed off on them?

So without further adieu, I bring you Quiznos' singing teratomas!

Have a great weekend!

Why the City is Now Wasting Less of my Tax Dollars

Just a follow up on the couriered packages sent by the City.

I have a friend and colleague in Ottawa Public Health with who I had addressed my concerns regarding the delivery costs of questionably useful materials.

I have been reassured by him that indeed this has been looked into and considered and here is the scoop:

  • With regards to the mailing on shaken baby syndrome, the costs were funded by the Province, not the City and it was sent out to less than 500 local family physicians at a cost of closer to $2,000 or $4 per shipment.

  • With regards to the actual content, the City is going to take a step back to take more time to evaluate the usefulness of the materials sent out.

  • With regards to offices where there are multiple doctors (like my friend who in his 11 person practice received 44 shaken baby posters with each doc getting their very own 4) they will only be sending one or two for the whole practice.


  • My friend with the City noted that he was told the cost of the shipment was less than what Canada Post had offered, and I believe that only with regards to courier costs, or same day delivery costs. At $4 per shipment, the cost is roughly the same as it would have been with regular mail without any discount whatsoever applied for bulk.

    I discussed this matter with a high-ranking executive from Canada Post and was assured that there was no way that any type of couriered shipment could be cheaper than a bulk rate on regular mail.

    I will continue to follow with interest the issue on mailing costs. I have asked the gentleman from Canada Post to provide me with a name of a salesperson so I can have him or her speak to my friend over at the City and hopefully I will have a final answer on that matter of cost soon.

    Regardless, kudos to the City for looking into the matter so quickly and for making some very positive changes!

    New Chinese Adoption Rules Ban the Very Obese

    Since 1985 there have been close to 60,000 children adopted from China to parents in the United States. Last year alone there were close to 8,000.

    The Chinese government, undeniably not one to be overly concerned with rights, recently imposed some new rules whereby they've imposed some exclusion criteria on foreign adoption applicants. They've barred applicants who are unmarried, over 50, on antidepressants, have a "severe facial deformity" or meet the NHLBI's definition of extreme obesity with a body mass index greater than 40.

    I'm at a bit of a loss.

    On the one hand, there's no doubt whatsoever that having a body mass index greater than 40 confers very dramatic medical risk of both illness and premature death. On the other hand, so too does smoking, a recent admission to the hospital for congestive heart disease, a diagnosis of cancer, and a myriad of other medical conditions.

    Now it's possible that China discriminates against the other medical conditions as well, though certainly the article I read didn't mention them.

    Bias against the obese is longstanding, not just in China, but globally. I still see political cartoons, regular cartoons and articles vilifying the obese. I still see "fat suits" advertised as fun Halloween costumes. To read about some of the bias against obesity in American society, read Kelly Brownell's fantastic paper on the matter.

    Do you have negative attitudes towards the obese? Studies have shown that most of us do, there have even been studies that show folks with weight to lose look down on other folks with weight to lose.

    The first step to stopping bias is identifying it. Take stock of your own responses and thoughts on obesity. The next time you interact with an individual with weight to lose, try and identify whether or not you've got negative associations, and then more importantly, try to rid yourself of them.

    Obesity is predominantly a disease of the environment, not the individual.

    I wonder whether or not China's new rules will affect the number of children adopted. While the BMI over 40 crowd is not terrifically large, it is growing rapidly. I imagine the bigger hit will be the ban on folks taking antidepressants, they're much more common, perhaps partially because societal bias as a whole is so damn pervasive and so damn depressing.

    Stupidest Weight Loss Drug Ever?

    Compellis Pharmaceuticals has secured a patent on a new pharmacological means to treat obesity.

    Their solution?

    A nasal spray that would take away your sense of smell and taste. The theory I suppose, if you don't like what you're eating because you can't taste it you'll eat less. If you read their patent application you'll find that it worked on rats!

    While I'm well aware that weight is a terrifically important determinant of health and that folks will try a lot of crazy stuff to help themselves lose, do the folks over at Compellis really think that people would be willing to give up one of life's most basic pleasures, the taste of food, to lose weight?

    Clearly they must, and certainly people might be willing to put up with that loss of pleasure while they lose weight, but as with any weight loss effort that involves any sort of suffering, as soon as the scale stops whispering sweet nothings, most folks will decide they want the suffering to end.

    As I've stated in many posts before, unless you like the way you're losing weight; unless you plan on continuing to live that way forever; it'll never stay off.

    If only Compellis were a public company that I could sell short....

    Kids, remember to drink your Diet Coke Multivitamin!

    Perhaps someday soon we'll be seeing ads like this old one for Ovaltine from Coca Cola soon.

    According to Beverage Digest, the Coca Cola company plans to roll out Diet Coke Plus.

    Plus what you ask?

    Why plus vitamins, minerals and herbs and course.

    A veritable multi-vitamin in a pop can.

    Because nothing says healthy like Diet Coke.

    Except perhaps Ovaltine (chocolate vitamin powder added to milk) which according to the old ad has:

  • More vitamin C than 4 ounces of orange juice
  • More vitamin B than 3 servings of oatmeal
  • More vitamin D than 10 ounces of butter
  • More protein than 3 eggs
  • More vitamin G (for those of you confused, Vitamin G is riboflavin) than 1 pound of sirloin steak
  • More iron than 3 servings of spinach
  • More niacin than 6 slices of enriched bread
  • More vitamin A than 2 servings of peas
  • More calcium and phosphorus than 2.5 servings of American cheese
  • And more food energy (calories) than 2 dishes of ice cream.

    MMMmmm food energy.

    Ovaltine by the way is still around. Now they also market directly to children with a product they call Max for Milk complete with happy cartoon boy.

    Their website states,
    "Just simply mix it with cold milk for a wholesome milkshake drink your kids can enjoy every day."
    They also state,
    "Each drink is made with the wholesome goodness of barley and malt, and contains 11 vitamins and 4 minerals – great to keep kids going! It also contains no artificial colours or sweeteners and is low in fat."
    It's a good thing for Ovaltine that no one makes ice cream with multivitamins in it because that would be direct competition.

    Everyone knows ice cream would be a great choice if there were multi-vitamins included!

    Multi-vitamins make everything healthy, chocolate milk, carbonated beverages - you name it, it'll be good.

    If you're confused here, please go back and include dripping sarcasm with the last two lines.

    Frankly as far as I'm concerned, I'm turning down Ovaltine and Diet Coke Plus in favour of my new favourite functional food - Fibe Mini! I don't know what's in it, but as you can see from the following video, drinking it will morph you into a winged, lightsaber wielding superhero able to vanquish giant life size parasites and bacteria and bring joy back to the world!

    The Skinny on Low Fat and Breast Cancer

    It's because of headlines like this that I actually started writing this blog,

    "Lower-fat diets cut breast cancer recurrence: Study".
    They've been all over the net and newspapers over the course of the past few days, all because of a study that has followed 2,437 breast cancer survivors and compared those who followed a low-fat diet with those that didn't with regards to breast cancer recurrence.

    The results, trumpeted loudly in the press, report that those with a lower fat diet had a 24% lower risk of breast cancer recurrence over a 7 year period.

    Sounds great right? Low-fat must be the only way to go right?

    Probably not.

    It's not that a low-fat diet is a bad thing. It's not that I'm telling people not to follow low-fat approaches. It's just that the most likely reason for the reduction in recurrence in the low-fat group is the fact that the low-fat group lost weight.

    Obesity and the risk of cancer is a very well established fact. The biggest study looking at cancer and obesity was conducted by Calle et al and published in the New England Journal of Medicine. The authors, after following over 900,000 men and women for over 16 years concluded that 20% of all cancer deaths in women were associated with overweight and obesity as were 14% of all cancer deaths in men.

    To me, there's no doubt that there were some women in the control group (the non low-fat group) that also lost weight. I have no doubt because many women will take the diagnosis of breast cancer and use it to inspire them to live much healthier lives than before their diagnoses, improving their fitness, their dietary choices and quite often, their weights. Given that there is no formal in-paper comparison between low-fat weight losers' and regular fat weight losers' risks, and given that I'm by nature a highly suspicious guy, and given that an article stating that a low-fat diet reduces breast cancer recurrence risk is a much more exciting result than one that does not, I can't help but wonder if either the authors had those numbers and chose not to report the result that any way you lose weight is good, or if they purposely avoided crunching those numbers so as not to have to report them.

    This argument wasn't lost on the American Cancer Society either, who in the press report I read specifically pointed out,
    "that studies focusing on fat in the diet have not clearly shown this to be a breast cancer risk factor, although being overweight has been found to raise breast cancer risk, especially for women after menopause."
    Clearly the argument wasn't lost on the authors of this study either as the last line of the Reuters piece reads,
    "The researchers noted that women who ate less fat lost weight, and that the weight loss may have been at least partially responsible for lowering the relapse risk rather than the reduced fat intake alone."
    So if you've had breast cancer should you go on a low-fat diet to improve your chances? Sure, but ONLY if you actually feel like you can live on that low-fat diet forever and more importantly ONLY if your low-fat diet leads you to lose weight.

    Remember, weight loss has nothing to do with low-fat or low-carb. Weight loss has everything to do simply with lower calories, and whatever way works for you is good.

    The World's Best Potato Latkes!

    So Chanukah lands on Funny Friday, and therefore I've got to find something appropriate to both celebrations.

    I found something great, but first something else great, a recipe for my wife's potato latkes:

    Be forewarned - high Calorie, not very nutritious, but very, very yummy. Considering she makes them about twice a year, I feel fairly safe.

    If you shape your latkes to be no more than about 1cm thick and about 10cm in diameter, we worked out the calories last year to be about 80-100 per latke.

    6 potatoes peeled, pared, grated and drained well (squeeze out as much of the potato juice as you can)
    One small onion, grated
    3 eggs
    1 tsp salt
    1/2 tsp pepper
    1/4 cup flour
    1 tbsp canola oil
    2tsp baking powder
    Canola oil for frying

    Combine all ingredients and either fry in pan with oil (flipping once when edges start to get crispy or look brown) OR bake in oven at 400F on oiled baking sheet/tin foil, flipping when edges look brown (obviously far fewer Calories if baked). Let cool on very absorbent paper towels and enjoy!
    So now on to Funny Friday!

    How does SpongeBob singing Adam Sandler's Chanukah Song Part 3 sound?

    The internet is one strange, strange place.

    Happy Chanukah!

    Why Does the City Waste My Tax Dollars Part II


    15 minutes ago I received another couriered package from the City of Ottawa Public Health department. My understanding is that these packages go to every doctor in Ottawa.

    In this high priority package (it was shipped via DHL Express, not DHL Ground) was 4 copies of a poster that advises a person to hold and rock but never shake a baby.

    Indeed an important message, but really, did it need to be couriered to me express? Is tomorrow National Shake Your Baby Day and therefore an urgent pressing emergency public health measure?

    Again I went to DHL's website and plugged in the dimensions and weight of the parcel. I wasn't given the option of DHL Express pricing but DHL ground had a rough cost of $15 per 4 posters.

    Using the CPSO Doctor Search tool 3,359 doctors in Ottawa.

    That's $50,385 in courier costs!

    So for those keeping score, in 9 weeks our City has spent $100,770 to courier doctors a bunch of pretty much useless and certainly non-urgent materials (in early November I received my urgently couriered Flu Pandemic Preparedness Handouts).

    Sure doesn't give me any warm and fuzzies.

    UPDATE: See most recent post detailing City's investigation

    The Easy Way to Read a Food Label

    I scratch my head when I look at food labels. I can't imagine that the average consumer cares to know all of the information provided and can't help but wonder whether or not having so much information may simply cause the consumer to avoid using it.

    Take for example Canadian Member of Parliament Rick Dykstra. In discussing the unfortunately defeated Bill C-283 he commented on his use of food labels,

    "The frustrating part for me is that I don't know what three-quarters of the things are that are actually on the label itself, and then I need to get a magnifying glass to read what I don't know."
    Rick's definitely not alone in his confusion, so for all of the Ricks out there, here is the quick, down-and-dirty, 4 step Nutrition Facts label reading program.

    Step #1: Look at the Serving Size. Until Health Canada mandates more useful and toothful labeling laws, serving sizes are pretty arbitrary. Sometimes you'll see things like 1/2 a cookie serving sizes or 1/4 of a bag of microwave popcorn. Multiply everything on the label by the number of "servings" you personally imagine consuming.

    Step #2: Look at the Calories. If you're watching your weight or concerned therein, less is more when it comes to Calories.

    Step #3: Look at the fats. If you can avoid buying foods with trans-fats, do so. When it comes to saturated fats, less is more but don't sweat them too much. When it comes to unsaturated fats, don't worry about them at all and in fact, more is more.

    Step #4: Look at the sugar. 4 grams of sugar per teaspoon (so you can quickly divide and see how many teaspoons of sugar you're getting). Less is more.

    Seem too easy? Want some advanced techniques?

    Advanced Step #1: Look at the fibre content. More is more.

    Advanced Step #2: Look at the sodium content. Less is more.

    Advanced Step #3: Look at the ingredients list. If sugar is listed as one of the top three ingredients, try and find an alternative.

    Don't worry about the percentage daily values stuff, don't worry about the micronutrients (the various vitamins and minerals), and don't worry if you don't know for instance how much sodium is too much. The more frequently you look at the labels, the more of a grounding you'll get in what's out there and the more you'll know what's a lot and what's a little.

    With regards to micronutrients and the percent daily values stuff, I recommend a multivitamin, and the cheap ones by the way work fine.

    Consider a multivitamin nutritional insurance, not a license to eat poorly. Just because I have car and home insurance doesn't mean I don't buckle my seatbelt, drive safely and lock my house when I leave.

    If you're concerned about your health, not reading food labels before you eat something is comparable to being concerned about your finances but not looking at price tags when you go shopping - a bad idea.

    Low-fat Foods May Make you Fat!

    At least that's what the headlines are going to read once they get hold of Brian Wansink's latest paper.

    Published in this month's Journal of Marketing Research, his paper (full-text of his article freely provided by Dr. Wansink on his website www.mindlesseating.org in Word format in the "Free Stuff" section) explores the influence that a label like, "Low-fat" has on consumption.

    First some minor background and the take home point of this blog entry:

    LOW FAT DOES NOT EQUAL LOW CALORIE!
    Now onto the studies.

    In study #1, University open house attendees were taken to one of two bowls. One contained regular M&Ms labeled, "New Colors of Regular M&Ms" and the other the same M&Ms this time artificially labeled, "New Low-Fat M&Ms".

    Low-fat labeling led participants in the study to eat 28.4% more M&Ms, and interestingly participants who were already classifiable as being overweight (via body-mass index means), took 16.7% more M&Ms than healthy weight participants.

    Dr. Wansink and authors postulated that perhaps this was due to the fact that the "Low-fat" label seemed to affect the over-underestimation of calories by overweight participants compared with healthy weight participants.

    Only problem with this experiment is the fact that there is no such thing as a "Low-Fat" M&M therefore one might assume that with a truly low-fat product, the increased consumption due to the labeling might not be reflected in consuming more calories.

    The thing is, you'd likely be wrong.

    Dr. Wansink's no dummy and of course, he surveyed the fat and calorie content of ALL brands of chocolate candies, bars, cookies, milk drinks and muffins with at least a 5% market share. He found that 17 products had both a "Regular" and a "Low-Fat" version. The serving sizes were comparable for all products.

    On average the "Low-Fat" products contained 59% less fat than their "Regular" counterparts, but ONLY 15% fewer calories!

    Taking his original study with M&Ms, if there were a low-fat M&M with 59% less fat and 15% fewer calories than regular M&Ms, participants would still have consumed 9% more calories from the low-fat product.

    Dr. Wansink goes further and quotes the work of Marion Nestle who found that ingredients used to replace fat often tend to make people hungrier and therefore he feels that in fact eating "Low-Fat" labeled products may well causes us to consume even more than an additional 9% of calories!

    To ensure that this wasn't due simply to the fact that "Low-Fat M&Ms" were something perceived as a too good to be true item that then led to over consumption, Dr. Wansink performed a similar experiment using granola. He found very similar results and then when comparing his statistics with real world products found that the "Low-Fat" label would lead a person to consume 33% more calories than the "Regular" version.

    The paper concludes:
    1. Labeling snacks as “low fat” increases food intake
    2. For normal weight people, “low fat” labeling increases consumption most with foods that are believed to be relatively healthy.
    3. For overweight people, “low fat” labeling increases their consumption of all foods.
    Bottom line - Don't get conned by Big Food.

    Don't take anything at face value. Ignore claims like "Low-fat", "Low-carb" and definitely be very leery of both industry sponsored Healthy Options stamps like the as “Sensible Snacking” (Nabisco/Kraft), “Smart Spot” (Pepsico), or “Healthy Living” (Unilever) and even non-industry sponsored stamps like the Health Check from the Heart and Stroke Foundation.

    Just because there's a claim or stamp on a product does not make it healthy, nor does it mean it's low calorie.

    Whitey, Yellowy, Goopy Gold - $5,000 a Litre Biodiesel!

    There's gold in them-thar bellies!

    I'm not sure if this qualifies as a smack your forehead, why didn't I think of that story, but you have to admire the lateral thinking.

    Lauri Venoy, a Norwegian businessman, has apparently signed a deal to obtain over 11,000 litres of human fat a week.

    What will he do with all that fat you ask? Well he sees it as white gold - he plans to convert it into combustible, foreign-oil-dependence killing, car-fueling, biodiesel!

    Wisely, he's not basing his business in Norway, but rather in the USA where there is much greater abundance of natural resources.

    Ever the businessman, Venoy plants seeds for growth stating,

    "Maybe we should urge people to eat more so we can create more raw material for fuel"
    Thankfully for Venoy, there is no shortage of people trying to convince us to eat more (Big Food, and these days in Canada, Health Canada) and with 65-75% of North Americans overweight or obese, there's no shortage of "raw materials".

    Don't worry about the cost at the pumps though, the $5,000 a litre is for the patient.

    I imagine once outside of the body, human fat's probably pretty cheap.

    Scary Poppins!

    As more frequent readers of my blog know, Fridays lately have not been so funny. The problem was during the posting of the Canada's Food Guide series, I had a tough time finding anything humourous.

    Now that the series is completed, I can go back to the relatively new tradition of Funny Fridays.

    Today's post - a brilliant recut of the original Mary Poppins film to create a trailer for the new horror film, Scary Mary.

    Have a great weekend.

    Enviga - Burn your Money....I mean your Calories

    Coca Cola and Nestle, a match made in marketing heaven, are about to release Enviga, which according to Dr. Rhona Applebaum, the chief scientist of the Coca Cola company (that's what the press release calls her anyhow), the "perfect partnership of science and nature".

    So what does this perfect partnership entail? A crap load of caffeine (3x the caffeine of a can of Coca Cola), and a component of green tea lovingly named epigallocatechin gallate, or EGCG. And EGCG, what does it do? According to Dr. Hilary Green, corporate shill and sell-out scientist for Nestle, it "speeds up metabolism and increases energy use, especially when combined with caffeine". Put this all together and Coca Cola and Nestle's marketing campaign tells us that if we drink 3 cans of this stuff a day, we'll lose weight!

    Can you say ka-ching?

    So first, let's ask how much weight we're talking here. According to the companies', an extra 60-100 calories a day or 6-10lbs per year. Remember that number, I'll come back to it.

    So how much do we have to pay for the privilege of losing an extra 6lbs in a year? Roughly $1500 given that each can costs on average $1.39 and you'll have to drink over 1,100 of them a year.

    Marketing in the test market of New York is fierce with billboards stating, "Burning Calories is now officially delicious", and "Be Positive, Drink Negative".

    The science by the way, surprise surprise, is lacking to say the least, but I'm not even going to bother getting into it.

    I know, you've been reading my blog and are baffled by the fact I'm resisting an opportunity to provide references.

    Here's a case where I don't need references, but if you want some, feel free to turn to the Center for Science in the Public Interest who 3 days ago sent a cease and desist letter to the Enviga folks.

    Why don't I need references? Let's go back to that 60-100 calories burned. Let's even assume it's true. What else burns 60-100 calories - drinking 8 glasses of fridge cold water a day or really drinking 8 glasses of any cold zero-calorie beverage a day (because it takes energy to raise the temperature of the cold liquid) or taking just three extra 5 minute walks a day.

    Any zero-calorie beverage marketers reading my blog? If so, take the wind out of this Frankenfood's sales by starting your own drink negative campaign!

    So what would you rather do? Drink 8 glasses of cold water a day, go for three 5 minute walks a day, drink 4 glasses of cold water and take one 7.5 minute walk a day, go for three 10 minute walks a day, or would you rather spend $1500/year and in so doing help pay the salary of a clear researcher of the night who actually put her name behind the statement calling Enviga a "perfect partnership of science and nature"?

    Shame on Dr. Rhona Applebaum selling her name that way, shame on Dr. Hilary Green for promoting shaky science as fact, and shame on you if you buy into this incredibly stupid campaign.

    Brian Wansink's Mindless YouTube

    Brian Wansink, the head of Cornell's Food and Brand's Lab is a great researcher and a fantastic speaker. I first saw him lecture in Vancouver at the Obesity Society conference last year and recently he released his first mainstream book, Mindless Eating (book review to come in coming weeks).

    A few weeks before I started the Canada's Food Guide series, he appeared on 20/20 talking about some of his experiments. His work focuses on the invisible cues that make us eat - how plate, cup and container size affect our portions and he offers some great suggestions on how to help remove those cues from our lives.

    Here, through the magic of the Internet and more specifically You Tube is a part of Dr. Wansink's 20/20 segment:

    Colonel Sanders - Your Personal Health Guardian

    As you can plainly see from this ad, the Colonel espouses a healthy living attitude as I'm sure that the football on the ad means that I should be playing rather than watching football.

    What's that? You think it's about eating a bucket of fried chicken while watching football?

    Couldn't be. You know how I know? Yesterday while researching KFCs plans to scare away invading aliens I stumbled across their nutrition resources in a page Con-Agra calls, "Keep it Balanced" and it was on that page that I finally learned how to manage my weight and enjoy fried foods along with a few wonderful quobesities!

    You see, according to the nutritional wizards working for Supreme Overlord Sanders (if you're confused, scroll down to yesterday's post),

    "Many quick picks like tacos and pizza are full of important nutrients [Hey, Health Canada LOVES nutrients!] providing three or four food groups all in one."
    So you see, they're SMART picks! So when I eat a pizza, I'm getting TONS of nutrients and basically a salad because I have tomato sauce with onions, hot peppers and pineapples!

    But Supreme Overlord Sanders, even you must admit it seems like the World is getting heavier quite quickly. Did you see the report that said that there were now more overweight Africans than underweight Africans [a huge blow to the clean-your-plate club motivational speaking wing]? Well, those nutritional wizards know what to do,
    "No single food causes weight gain [that's right, if you just eat one piece of food a day, you'll never gain weight]. It's about the total calories. So make your calories count by eating foods rich in nutrition [like Tacos and Pizza], and kick up the exercise a few notches when you eat more than you need."
    Clearly those Africans must not exercise enough!

    What I'll probably do for dinner - I think I'll have a KFC crispy twister sandwich (670 calories), along with KFC potato wedges (240 calories), a slice of KFC pecan pie (480 calories) and a large Pepsi (280 calories) and then when I get home, I'll just tell my wife and 27 month old daughter that I love them but the Colonel says I have to kick up my exercises a few notches and then I'll go for the 3 hours of running that I would need to take to burn off the over 1600 calories I ate for dinner at KFC. You know, I guess that's unfair, I do after all need some calories for dinner, so I guess I'll go for a short 2 hour run and keep some of those chalk full of nutrients calories just for me.

    Gee, those folks over at Con-Agra foods sure are smart! I hope that Health Canada consulted them when creating their new Food Guide.

    Great news! On the Food Guide's revision 12-member Advisory Board sits Ms. Carolyn O'Brien, the Director of Scientific & Regulatory Affairs at the Food and Consumer Products Manufacturers of Canada - a purely industry based organization whose members include KFCs Con-Agra!

    Hurray! Way to go Health Canada! No one knows nutrition better than the Colonel, and no one cares more about the health and welfare of Canadians than the food industry. Right?

    A Giant Warning to Space Aliens!


    As if enlightened extra-terrestrials needed another reason to avoid popping by!

    The first corporate logo to be visible to the Hubble telescopes of other intelligent lifeforms - KFC.

    I wonder if they'll think the Colonel is the supreme overlord of Earth?

    All hail Supreme Overlord Sanders, champion of deep fryers, feeder of families and scourge of chickens!
