So these soups were on sale and I was trying to figure out how to get the most bang for

第二類條件句型

So I went down a little bit of a rabbit hole to see if there were a SOUP CONSPIRACY.

Now, people look at calories on products for all sorts of reasons; some soups are marketed

as Light for people who look at 70 or 80 calories and think, that's good, I want a low number,

while some people think 70 calories is not worth the effort of opening the can.

A savvy consumer will look at the fine print and see that's per serving, and a serving

is one cup, and I don't know if anyone in the universe opens up a can of soup and carefully

pours out just half of it, but assuming you eat the whole thing like a normal adult who

eats canned soup by themselves because they can't cook and have no friends and are home

alone with only their microwave for company, of course you eat the whole can which has

And who doesn't expect to do a little arithmetic in the grocery store, two times 70 is 140,

which if you want a low number, is still pretty low.

It's kind of funny though because calories per serving means total calories divided by

number of servings, so multiplying it by the number of servings is really just undividing

Or maybe it's division that should be called unmultiplication?

Anyway maybe you want high numbers, life's too short and budgets too tight, so they market

the rich and hearty soups with 150 calories per serving!

Also about 2 servings per can, and 300 calories is a number worth opening a can for.

Funny thing though, both serving sizes are one cup but on the light soup one cup is 236

grams and on the rich hearty soup one cup is 253 grams.

On the one hand it seems intuitive that yes, rich food is heavier, mm look how rich and

gloppy, can you tell this video isn't a paid sponsorship?

But on the other hand fat and oil weigh less than water, foods weigh all sorts of things.

Luckily we can look at the net weight of the product and huh, it's the same for both

So does that mean light food isn't lighter?

I don't know, maybe there's more of it in the can.

But I do suspect there's something going on with these serving sizes, meaning we can't

really compare these advertised calorie numbers, and we can't just double the calories per

serving to get the calorie count for the can either, so, so much for arithmetic in the

See, for light zesty santa fe style chicken, arithmetic says 236 grams times 2 = 472 grams.

Which is clearly not helpful as the total grams is 524, not 427.

If we want to figure out how this 524 grams happens, we have to multiply 236 grams by

So don't get distracted by the suggestion of 2-ness, we don't know what this number

is… unless we treat it like any other variable and do algebra to it.

So let's just unmultiply this 236g, which means we unmultiply the other side too, and

Which is a very 2-ey number, but definitely not to be confused with actual two.

So now that we know how many servings are actually in here, we can multiply this 80

So if you were expecting 160 calories you're cheating by 11%.

And if you were expecting 33% fewer calories than a leading competitor that has 140 calories,

But what about rich and hearty chicken pot pie style?

Times 2 equals 506, but times “about 2” equals 524.

So once we unmultiply both sides by the serving size we see that this time about 2 equals

2.07, that really is about 2. and 2.07 times 150 calories is 310.5.

So if you were expecting 300 calories you're getting just 3.5% more than you bargained

So about 2 can be more than 2, it could be actually about 2, but what about less than

Is this can of black bean soup an organic alternative with the same amount of calories

Obviously it's a smaller can but maybe those organic black beans are really just that much

Serving size is still one cup, still “about 2” servings per container.

One cup equals 256 grams, times two equals 512 grams of soup with 300 calories.

This time, about two servings of 150 calories gets you only 237 calories, that's 79% of

the 300 you might be expecting when you read this label.

So according to this soup company “about 2” can mean anything from 1.58 to 2.22 and

I wondered whether that was about the legal range of what's allowed on the can so I

went and read the FDA guidelines for nutrition information and learned lots of interesting

Now between 2 and 5 servings you have to round to the nearest .5, but somehow numbers less

Other fun marketing details: Light is in a little spoon, rich and hearty is in a big

Organic is definitely an entire bowl that is a meal that is organic.

Also the chicken soups are inspected for wholesomeness, but steak and beef is USA inspected and passed

But servings aren't the only numbers with exploitable rounding rules.

According to the guidelines any calorie numbers over 50 get rounded to the nearest 10s place,

so this 80 might represent 75, or it might really be 84.9, which * 2.22 is 188 calories.

And then again, there's margins of error for how many grams in the can and in a serving

and maybe they round the number of ounces first and then convert that number to grams

and round again, which means the number of grams isn't necessarily accurate to three

significant figures, and I'm sure there's margins of error for everything, basically

Let's just take a moment to appreciate the layers here.

If all we want to do is know how many calories are in this can of soup, we've got four

A quick look at the label gets you an answer of 80 calories.

“read the fine print and do basic arithmetic,” which sounds like due diligence to me, gets

“read the finer print and solve an algebraic equation,” as ya do in a grocery store,

bumps that to 176, and finally, “read the Department of Health and Human Services plus

Food and Drug Administration 132 page guidelines plus do an advanced analysis with fuzzy numbers

that even I couldn't do without a special computer program” gets you to “up to 188+
