Do you guys have trouble with MSG in things?

For supper last night, I threw together cooked ground beef, a can of
green beans, a can of cream of mushroom soup, and a small can of
mushrooms.  The whole thing amounted to about 25 net carbs, so since
it looked like at least 3 meals, I should have been fine.

After only a couple bowls (less than I expected to eat), I started
feeling bloated like I'd eaten a whole bucket of mashed potatoes.  The
feeling stuck with me for the rest of the evening -- a few hours, at
least -- and I even had some mild heartburn, which I never get on LC.

It hit me after a while that it was the same feeling I used to get
when filling up at a Chinese buffet: bloated yet still hungry in an
odd way, and feeling like it's hard to take a deep breath.  I never
feel like that on low-carb, not even in the first week, when I'm
stuffing myself with pound after pound of meat to stave off cravings.

That made me think of MSG, which of course is an ingredient in the
soup.  I don't suppose it'll hurt me as far as diet goes (as long as
the soup was correctly labeled as per carbs), but it was awfully
unpleasant.

I guess I'll have to start making my own cream of mushroom soup.  That
should make it lower-carb anyway, if I use something better than
"modified food starch" as a thickener.
