I didn't even think about searching the web duh but now I did, and this is what the nabisco web site had for Grey Poupon Country Dujon Mustand:

So now my question is -- if I'm trying to calculate a recipe in fitday.com (someone suggested to me to have a separate log in for recipes) - the custom food input requires a fat #, since there isn't one (see above) how do you get around that?
