I have been wondering about something that Ella mentioned. I have a calorie counting book that also lists carbs etc and also I check out carb content from this site and the Dr Atkins book. I am confused though at the difference in carb amounts.
For eg, i have bagged salad leaves which are 2 carbs per 100g which is 2 large soup bowls full, yet Dr Atkins' book says that 1 cup of lettuce is 1.6 (iceberg), Ive also seen a marked difference with nuts.

Does anyone have an explanation for this?

Happy hunting
