What's in my yogurt today?

I have this thing about ingredients in my food. If I can't pronounce it right away, I'm skittish of it. Since I started paying attention to what's in my food, I've started actually looking up the ingredients in some of the things I eat. Out of curiosity, I looked up a few things.

Tricalcium phosphate: This has the nickname of 'bone ash'. It's in our bones and teeth, which makes it tolerable I suppose. The natural form of it is rather impure, so I suspect the form I'm eating right now (om nom nom) is slightly processed. Eh, I can deal with that.

Beet juice concentrate: That's the pink coloring. Oh my god it's not artificial. That makes me kind of happy. I can't recall the exact effects or suspected effects of artificial colors, but honestly, who cares what color it is? It's food. It all ends up the same color in the end, and that crap's got to end up SOMEwhere. If they're gonna fake-color it, the least they can do is use a natural coloring.

Vitamin A acetate: I know what Vita-A is. The acetate part got me, but I couldn't really find much information on why it's got that in the name. This is curious.

Modified corn starch: A thickening agent. Makes it less runny, I'd imagine, but where's the 'modified' part come from?

High fructose corn syrup: Boy. You know, this one's such a massive one it probably deserves its own entry. Suffice it to say that in the limited quantities I probably consume (lots of natural and from-scratch products means everything I eat doesn't have it) I'm probably okay, but it would be nice to NOT be eating something that requires that much processing.

I'd rather stick with my organic brand, but since this stuff was on sale and I had coupons for it (yay doubling of coupons), I was okay with it.

The cup is #5 plastic, which IS NOW RECYCLABLE IN MY AREA! Thank the gods for that -- because this is one of those brands that's narrower on TOP than on the bottom, precluding the possibility of using it for seed planting like I do for the other cups I get. Bah.
