A new study published in the November issue of the “American Journal of Preventative Medicine” and conducted by Dr. Russell Rothman and others at the Vanderbilt University Medical Center showed that a majority of people studied cannot understand basic food nutrition labels (read as: a majority of people cannot do the simplest math imaginable).
Two of the most amazing findings were that:
Two-thirds of patients surveyed could not correctly calculate the amount of carbohydrates consumed in a 20-ounce bottle of soda that had 2.5 servings in the bottle.
Just over half could calculate the number of carbohydrates in half of a bagel, when the serving size on the label was listed as a whole bagel.
Clearly, the problem is far larger than determining how many grams of saturated fat are in three Mr. Goodbars. More succinctly, Americans seemed mystified by simple multiplication.
More good news:
Researchers found that even patients with higher levels of education can struggle to interpret current food labels, particularly in situations that involve interpretation and application of serving sizes.
(Read as: even “educated” folk don’t have a clue).
When the Food and Drug Administration changed the mandates for nutrition labeling in 1990’s, their intent was to simplify and enlarge the labels. The mandate for larger text, a uniform design, and the use of categories and subcategories were all done so that even the densest American consumer could understand the nutritional differences between onions and Funyuns. According to this study, it clearly hasn’t worked. Apparently, the addition of a miniature slide-rule was also necessary.
If consumers don’t understand labels, then they will do one of two things: incorrectly assess the food they consume or disregard the labels altogether. Worse yet, as with the bagel example, some of the participants failed at tasks where there was no real math involved at all! The subject simply needed to “multiply” the “Total Carbohydrates” line on a food label by the number two.
Studies like this reveal more about the problems with our educational system than the “confusing” nature of food labels. Rule of thumb to teachers: you can’t let a student move onto a grade level they can’t count to (one, two, three, four, four, four). While I could continue into a rant on the failings of our nation’s public education system at the hands of politically correct and functionally inept teachers’ unions, I will hold back.
This study seems to speak for itself.


Re: VUMC Study: Americans fat, bad at math
Honestly though, you can't argue that the education system is at fault for people not being able to do those calculations... Maybe they just can't interpret the label. I know I've found myself hunting for info on those things.
I think more of a problem is that people don't even read the labels. So in that case it doesn't matter if they can't interpret them or do simple math.
Many recent studies (sorry no direct citations) have shown that we (children and adults alike) are stuck in an obesity epidemic. While I cannot deny that it is unacceptable that the these people can't do the math required to interpret a food label I think a bigger problem is our culure of instant gratification. This applies to everything from our boom of fast food joints to our lack of well rounded individuals.
But there is no quick fix to this problem.
My advice: force the kids to play outside, kick the Micky-D's and for gosh sakes... change the darn food labels! Those statistics are sad!

Ouch. That's really all I
Ouch. That's really all I can say about that study. Ouch.
Although, to play Devil's advocate, it could be worse (at least we have any schooling rather than some nations that have none).
