Carb Confusion

[shiftzor]

Oki, i confess that I suck at maths. However this bread has the following nutritional information:

per 100g
37.7g of carbs
6.9g of fibre

per slice
17.7g of carbs
3.2g of fibre

Now: 37.7g / 100 = 0.377 * 37g of bread (one slice) = 13.8g of carbs per slice. How can that be right? The confuzzlement is growing. :D

--------------------------------------------------

Oki I solved the problem:

Each loaf contains 800g of carbs and there are 17 slices in each loaf including ends.

800g / 17 slices = 47g per slice * 0.377 = 17.7g of carbs per slice.

Well that is a stupid assumption on their part and lazy considering that the ends weigh a lot more than the middle slices and thus each slice weighs less than 47g, evidently a lot less (37g). Moral of the story don’t trust packets of bread :D.

I always weigh bread and then do the maths, as one man's slice is another man's doorstop...

Shame really - I do enjoy the heel more than the middle. Never thought of adding a few carbs because of the extra grams. Of course, I never took any away from the middle slices either.;)

I just round up to the nearest/highest carb #

example if your bread is 17.7 per slice, I cover for 45 if having a sandwich with two slices, then count the "filling" of the sandwich and add that to the rounded up #

but then, I'd always rather be a little low than high at 2 hours---just my personal hang-up.

I weighed a few other slices and they all appear to have different weights. Somehow it never occurred to me that the real world is not as uniformed as I would have hoped, at least in food anyway :D.

CORRECTION: I meant 800g of bread not carbs.
