Where can I find a quick and easy list of total carbs/protein/sugars in common foods?
Please be careful around the words “total carbs”
In the USA and on their websites and recipes this wording will include fiber, which doesn’t need to be counted as it’s not digested and doesn’t raise glucose levels. Once they deduct fiber they then use the term net carbs. (Sometimes they also deduct polyols but that’s another topic as they do not all act in the same way).
Those USA net carbs are what we in the UK and most of the rest of the world simply call carbs (ie with fibre counted entirely separately). We don’t need to do any deductions for fibre and would end up with a falsely low amount if we did.
Sometimes a few uk based people use the same “total” carbs wording to mean including sugars, which to my mind is confusing and misleading. Our labels do list “of which sugars“ indented under the overall carb amount and those are already part of the (net) carb count. You only really need to bother with this “of which sugars” bit if the speed of sugars matters which is largely confined to type 1’s, and possibly T2 insulin users. Otherwise ignore it and count whatever is in the “carbs” listing.
