Labels Lie, eh?
Truly, there's a lot of variation and method in labelling. For instance, maybe "they" left out the fibre gram count on that ASDA label...?
Labelling varies between N.America and Europe as well, over here it's generally Total Carbohydrates (inc fibre) AND Fiber Per "some" Serving Size, rounded in grams, on the label if one is lucky. It's the way the regulations are structured. The European labels I have seen (including UK) on imported products shows (digestible) carbohydrate and fiber and usually per 100g (which at least gives you a percentage) and not per serving size...
Either way, we the eaters
must do the math and trust no one!
You have a very handy tool to verify any suspect label, at your disposal right above on the orange tool bar... the Loc Carb Tools page has a Carbohydrate Counter on it, with 4-6000 food products as listed in the governmental (US) Agriculture database.
Here are the results for brazil nuts (per 100g), N.American style:
Total Carbohydrates 12.80 g
- Dietary Fiber 5.40 g <---------therefore net 7.4g per 100g
Total Protein 14.34 g
Total Calories 656.00
Total Fat 66.22 g
Hope this helps!
