I’ve seen Idaho potato ads, and I’ve seen specific bread brands advertised…“Ironkids” fortified white bread, and also a brand of “white” wheat bread whose name I can’t recall (great advertising!). Mrs. Baird also does bread ads.
I always assumed that ads for staples like milk, eggs, cheese, etc., were “reminder” ads, like “Yes, milk is good for you, and no, eggs don’t have as much cholesterol as you think, and cheese does have lots of protein and calcium in it…”
California Cheese is doing a big push now with their “Happy Cows live in California” campaign. “Look for Real California Cheese.”
I also hear ads for both Californian and Mexican avocados. At least on local radio.
I guess with every new diet/nutrition fad, these “staples” of the American diet feel threatened, and have to remind people that they are worth consuming. I never gave up milk, eggs, cheese, potatoes, bread, or anything else, but I can see how diet/nutrition fads could threaten their bottom dollar to the point that they feel the need to advertise themselves. I’m sure bakers worried about the Atkins diet; I’m sure low-fat/cholesterol diets threatened eggs and cheese, etc…
The one thing I don’t see ads for is ordinary, regular, full-fat-who-cares BUTTER.
Not margarine, not “butter spreads,” not “butter alternatives,” but real no-holds-barred-manufactured-as-a-stick BUTTER.
I find that a bit curious.
