My wife keeps telling me the vinegar is good for the body...I think it is especially good for the pancreas, either that, or it was the liver. Sour, or bitter foods are equally as healthy.
Ketchup has a ton of salt, as well as an equally large amount of vinegar.
I'm sure you know peanut butter has a lot of protein in it, as well as a good supply of unsaturated fats (the easier to digest fats) and some other healthy goodies.
In Japan, they have this particular vinegar drink, called "Kurozu", or translated to English, "Black Vinegar". It doesn't have as big of a vinegar taste to it, actually much easier to swallow, but it's not my preferred drink, either <img src="i/expressions/face-icon-small-happy.gif" border="0">
I'm kinda blank on the ketchup idea, most stuff I put in on in Japan is usually Japanese foods...they don't even make it a condiment at McD's here, unless you request it. <img src="i/expressions/face-icon-small-sad.gif" border="0">
I miss cottage cheese! I usually would mix it with marshmallows and pineapple (Pineapple is another thing the wife said was healthy...but for the lungs!!).
However, I don't know if its age, or a bad experience, but many years ago I used to be able to take a large sum of salt, straight. Now, if I happen to over-salt my food, I get nauseated! Could've been when the ex had made some odd concoction of her Curry Rice and I happened to over-salt it because it had no flavor in it, and I was in a dehydration stage, at the time!! <img src="i/expressions/face-icon-small-tongue.gif" border="0">
