I like it too and use the food grade. It's worked better for me than EVOO, Almond, Shea.... I won't continue! I use the Tree of Life brand, which I found in a health food store w/other cooking oils.
NOW is a tricky brand they've gotten me on a few occassions. I don't think they make much in terms of food-grade products though. Spectrum makes both, but if you go to the section w/regular cooking oils you'll know for sure what you've got!
