In the US, in 2006, the FDA started requiring that food labels list grams of trans fat per serving. They were pretty vague about the legality of the requirement ("this guidance, do not establish legally enforceable responsibilities"), and they allowed for anything less than 0.5 grams per serving to be reported as 0 grams [1]. Every label since then shows grams of trans fat per serving. However, I have never seen any number reported other than 0 grams. Partially hydrogenated vegetable oil, once ubiquitous on packaged food labels, has practically vanished from them. For the most part it was replaced with palm oil (I suspect there was also a lot of serving size manipulation to take advantage of the 0.5 grams rule). It appears that the FDA is going to ban the addition of partially hydrogenated oil to food altogether by 2020 [2]. I imagine this (and perhaps similar legislation in other countries) is leading to increased demand for palm oil. This is not good for the environment nor Africa's primates. But how good is it for the primates on all continents, namely the humans eating palm oil all over the world? I suspect the answer is: way better than trans fats, but not very good.
