Note that today, one can easily find cake flour that isn't chemically bleached. Also, shortening manufacturers have gone to fully-hydrogenated oils, rather than partially hydrogenated, to reduce the amount of trans-fats. But some are still using palm oil, so it's not a total win.

I was just in the Smithsonian Museum of Natural History, where, just like you'd expect in a museum, 30-40% of the space is devoted to signs explaining what you should think about current political issues. There was one "exhibit" devoted solely to convincing you to do more dark-sky activism.

Even in that context, they couldn't bring themselves to recommend against palm oil. Their sign on that topic remarked that palm oil requires much less land per unit of oil produced than other oils, making it a pro-environment product.
