We could use the serving size field for this: if it contains ml, it might be taken from a per serving nutritional table. I have seen exceptions however. Unfortuately the web-interface does not allow me to search on that.

A better proxy is the existence of the transfat field. If there is data in that field, it is most likely a US or Canadian style nutritional table. Again this not a guarantee as other countries mark transfat as well. This results in 724 products. However some 60 products of this transfat sample have fat percentages around 100%, so we have false positives. We can add a fat limit of 94%, resulting in 629 products.

The US/Canadian style nutritional tables do not show the energy in kJoule. Thus if there is a value in that field, it is not US/Canadian. This results in 746 products. This is a low number, inducating that the field has not been filled in very well.
