You were thinking the same thing as myself. As a fluent speaker of both french and english, I've noticed that this a rather common mistake among anglophones. A food snob, would most definetly be a gourmet. A gourmand in french is more similar to a couch potato, although we all know, there are so few of those in France! In any case, a gourmand is a glutton!
On a side note. It can be quite amusing the amount of faux french uttered or labelled on products to be chic or sophisticated in the US, and the amount of incorrect or bizzarely used english used in France, especially in certain Parisian circles (thinking of le footing- to say jogging) to be a la mode. :)
