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%, i.e. any product that has fat percentage less than 94%. This results in 629 products. | 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.
