If you are into protecting the environment, then palm oil is worth thinking about. The better brands of peanut butter (which are not the 100% natural ones) use palm fat instead of hydrogenated fat. Healthwise this is good. But this fat comes from aggressive reckless deforestation in the tropics to make way for mono culture farms which are prone to pests and disease. So are sprayed with toxic pesticides which harm the poorly paid workers and whatever little wildlife might be left.
If a regular peanut butter (not the natural kind) lists "fully hydrogenated vegetable oils" on the ingredients, is it still something to worry about? I was under the impression that the partially hydrogenated oils were the ones that contained trans fats.
I don't know, the natural stuff actually has 10 more calories per 15g. I think it will be just as good for gaining weight.

Well... in the US things sold as "peanut butter" must be 90% peanuts (http://www.fda.gov/AboutFDA/WhatWeDo.../ucm132911.htm) so you're already working in a different market. If you don't like peanut butter, that's fine, but i don't see why you're bashing Skippy.

Some products really have been changed from "the good ol' days" by (evil) Corporations seeking Profit, (like tomatoes, chickens and bananas ), but peanut butter... not so much.
Fully hydrogenated vegetable oils become "saturated fats" and have no double-carbon bonds. So they're not trans fats. They're equivalent to say... lard.

PB sandwich -> regular PB
Spooning -> natural
'0g trans fats' is code for '0.49g trans fats per serving'. There's a 'fat free' cooking spray out there that's just plain oil, using the same sneaky labeling that your peanut butter jar is using.

Essentially, they take the fat and just force hydrogen into the fat molecules such that the molecules become rather rigid. Though they may become structurally "equivalent" to saturated fats when there are no double-carbon bonds, that would be the equivalent of saying partially hydrogenated oils are the "equivalent" of poly-unsaturated fats. Just stay away from hydrogenated oils in general.

See e.g. the three pictures here: http://en.wikipedia.org/wiki/Trans_fat#Chemistry
The ratios of different fatty acids in fully hydrogenated plant oil might be different from animal fat, (similar to how different protein sources have different amino acid contents ) but i haven't seen that raised as an issue.
As to the health impacts, well saturated fat is the OG bad nutrient... it's been somewhat rehabilitated of late, but not too much. All of these designations of good and bad are based primarily on the kind of epidemiological observational studies that measure intermediate markers that are considered around here to be fatally flawed, so as far as i know there is not significantly stronger evidence that one should avoid trans fats than there is that one should avoid large amounts of meat.
