How Many Calories Your Meal Has May Depend On Which Tracker You're Using

First, let me get this out of the way.

The currency of weight is calories. True, not all calories have the same impact on health or satiety, and also true, people aren't walking math formulas, but that doesn't change the fact that you need a surplus of calories to gain and a deficit to lose, and that the false dichotomy suggesting it's only worth caring about either quality or quantity of calories is just plain dumb.

But the story here isn't about that. The story here stems from the fact that my office is currently in the development stage of a mobile app which in turn will include a food diary.

Right now we're trying to figure out which calorie and food database to licence, and as part of that process one of our office's terrific RDs, Lauren Lejasisaks, chose 4 online recipes and crunched numbers using myfitnesspal, calorieking, and another third party database that we're considering licensing.

Turns out, they're all different. And not by small margins! The very same ingredients entered into those 3 different databases yielded results that differed by as much as 40%.

As to which is right?

I have no idea.

And it probably doesn't matter as much as you might think.

Though there's certainly value in having an inkling of where you might be at calorie wise (or carb wise if you're tracking that instead), probably the bigger value of record keeping is in the context of its service as a conscious reminder of the behaviours that you're trying to change. And if you're keeping a food diary regularly, you'll be reminding yourself multiple times per day, and so long as you don't use your food diary as a negative, blunt, tool of judgement, those reminders will help you to make more informed and thoughtful dietary decisions.

The Ontario Science Centre Just Hosted Cheetos' 3-Day, Immersive, Kid-Targeted, Advertisement

From the WTF files comes Ontario's Science Centre's hosting of the Cheetos Museum this past Mother's Day weekend.

What's a Cheetos museum?

It's a mobile, immersive, advertising experience for Cheetos.

Was there any science you ask?


The "promotional activity" (that's what it was called by the Ontario Science Centre in a now no longer hosted webpage online) involved hunting for Cheetos with identifiable shapes, swinging on a Cheetos branded swing, and taking pictures with Cheetos' mascot Chester.
So why would the Ontario Science Centre have hosted it?


I mean it's difficult to imagine it was there for any other reason given there's zero scientific content. The timing also seems to suggest money as the likelihood is that Mother's Day weekend is one of the Science Centre's busiest of the year - and that would command higher dollars.

All this to say, a live exhibit demonstrating the science of marketing junk foods to kids, by marketing junk food to kids, probably isn't one I'd have recommended to the Ontario Science Centre.

(And I don't think the Ontario Science Centre is all that proud of it either given there's not a tweet or a Facebook post from them to be had about this particular promotional activity.)

Pro-Tip: Copying Food Industry Press Releases Is Neither Helpful, Nor Journalism

So I saw this story published by Global News. It's about grain consumption in Canada and the headline sure is strong,
"University of Saskatchewan study shows importance of grain to Canada’s diet".
When I clicked through I read about researchers who by way of a cluster analysis of Canadians' grain consumption patterns, concluded that 80% of Canadians aren't eating enough grains and that as a consequence, they're apparently at risk of deficiencies in folic acid, some B vitamins and iron.

Oh, I also learned that
"there's less research supporting the benefits of enriched grain foods, sometimes referred to as refined grains"
and that refined grains are,
"important food sources for delivering key nutrients in the Canadian diet".
And that
"research suggests eliminating grain foods from diets is not associated with the body mass index (BMI)."
That the story reads like a press release is not a coincidence, because the same day the story ran, so too did this press release from the Healthy Grain Institute.

When I compared the two, it turns out that the Global News story was 49.5% identical to the Healthy Grains Institute press release.

Personally, I don't think the information in the press release warranted any news coverage, but if you're going to actually cover it, at the very least it'd be useful (and I think expected) to see:
  • That there actually isn't a published study, but rather just a presentation at a conference that was being hyped by a press release. 
  • Anything at all about what confounders were considered (or not considered) in the cluster analysis.
  • The proven and significant limitations of food recall based analyses.
  • The risks associated with increased intakes of refined grains. 
  • The funding of the "study" (not suggesting the research isn't useful, but rather that there isn't yet a published study to evaluate) by the Saskatchewan Wheat Development Commission (SWDC), the Alberta Wheat Commission (AWC), the Grain Farmers of Ontario and Mitacs, a Canadian not-for-profit funding agency supporting industry-academia collaborations
  • That Nutritional Strategies Inc. (the quoted co-researcher's employer (he's the VP)) provides food, nutrition and regulatory affairs consulting services for numerous food and beverage companies and food-related associations
Small wonder why people are confused about nutrition if food industry press releases about unpublished studies are copied and repackaged as news.

Why Do We Report on Diet Studies As If Patients Adhered To Their Prescribed Diets?

It happens all the time.

Researchers recruit participants for a diet study and randomize them to particular diets.

The participants don't adhere to said diets particularly well (and this is putting aside the known and glaring inaccuracy of dietary recall), and the macronutrient breakdowns of what they report eating are nearly always different from the macronutrient breakdowns of what they were instructed to eat.

And yet the researchers write up their studies as if their prescribed diets were followed, and consequently so too do journalists.

So here are my two asks.

1. Unless you're writing or reporting on diet studies conducted in metabolic wards, please treat their results with tempered enthusiasm.

2. And if the difference between two dietary outcome arms isn't likely to be clinically meaningful (like say the difference between weight losses of 3.3 kg, 4.6 kg, and 5.5 kg at two years (and bonus points if you get this reference right out of the gate)), maybe hold off on declaring one diet to be the world's best?

If You Need Proof The Food Industry Doesn't Care About You, Look No Further Than Smucker's "No Sugar Added" Jam

So I was shopping the other day.

We were making a dish that included apricot jam in a sauce and I was having a peek at the various offerings on the shelves.

I grabbed Smucker's Apricot Jam and noted that the front of its package highlighted the "fact" that it had "no sugar added".

The label of course told a different story.

It told me that the second ingredient was "white grape juice concentrate", which is likely on the order of 60% sugar by weight.

So yes, sugar was added.

I expressed my indignation on Twitter and Smucker's responded to tell me that they appreciated my feedback, that the concentrated white grape juice was meant to add "fruit flavor" as well as serve as a sweetener, and that according to the letter of the law, it was legal for them to state that their product contained no added sugar.
Now the good news is that at least in Canada, the addition of white grape juice concentrate, which of course is just the addition of sugar, will soon preclude Smucker's front-of-package "No Sugar Added" claim.

But of course if Smucker's actually wanted to do right by its customers it wouldn't be waiting for the Canadian Food Inspection Agency's regulations to change.

But that's not what Smucker's is about. Smucker's, like pretty much all publicly traded food industry players, is about profit, and their "No Sugar Added" jams are great case studies in how we shouldn't wait for the food industry to do the right thing, because unless the right thing aligns with profits, they're not going to do it.
