I must admit that I don't specifically exclude items with HFCS. I suspect there's some in my ketchup and I often joke that they'll have to pry it out of my cold dead hand.
I've tried eggs with salsa, and they're okay, but they're just not ketchup. As well, we make homemade beef/turkey burgers and again I just want my ketchup on it.
My bigger issue is the addition of sugar (no matter what kind) to diet products. I'm not a frozen dinner fan (make my own bulk/freeze stuff), however, I don't think there's a frozen dinner that doesn't have some kind of sugar in it. It may not be labeled with sugar but there's usually some form of it somewhere. Same with lower-cal snacks. They'll be marginally lower in calories (twice the price though) and have pretty much the same ingredients than they're higher cal counterparts. Oh and low fat is almost certainly beefed up with higher sugar.
Sigh... any wonder I'm moving more towards things I make myself. I've discovered I can make a pretty reasonable high protein chocolate zucchini cake. It's not replacing cakes/brownies though, it's more of a homemade protein bar. I don't usually take 3 pieces at once, but comparing them to the last ones I looked at:
Costco's (weider) protein bar: 240 cals, 20g protein, 30g carbs, 2g fiber, 5g fat
3 pcs (1/8 of 9x13" pan) of mine: 235 cals, 21g protein, 29g carbs, 9g fiber, 2g fat
Okay, some of it is cost-driven as the bars are $40 for 15 of them. However, HFCS was the first ingredient.
