Calories and carbs question (buy, sugar, better, cuisine)

[follie]

I have a food science question.

How can a food have 5 grams of carbs per serving, but only have 10 calories per serving?

Each gram of carbohydrate has 4 calories, right? So how can something that, in theory, should have 20 calories per serving have half that?

Is that from the food label? can you post a picture??

I think that the math is often off. See here:

it supposed to be 72 cal, and 9 cal from fat ( looks like they manipulate the numbers to make people believe that they eat less calories)

here is a better one:

16 gm fat = 144 cal but their count is only 10 (?) cal

what about this one?

5 gm = 45 cal ( listed 30 )
30 gm carbs = 120 cal
7 gm protein = 28 cal
total 193 cal listed 140 cal

You subtract dietary fiber, and total calories are to the nearest 10.

I don't know about calories from fat.

Carbs are carbs and fat is fat. I would sooner get my calories from fat, protein and fiber than sugar or simple carbs. If you try to eat high fiber and high protein whenever possible, that's the best you can do.

Grape nuts and rib-eyes. YUM

Somebody made a calculation error, or maybe somebody's just really bad at basic arithmetic?





... But seriously, I'd like to know the answer to this issue too.
