Good advice; or lunacy abroad?

Wandered onto an American food safety site, and came away as though I’d been hit with a large wet, flat fish across the face!

 Seems as though, all the years I’ve been taking my wife (and sometimes family as well) I’ve been placing them in grave danger, according to some advice on this same website!

Before ordering our food, apparently I should have called out, presuma-bly in a loud voice, to “ask that your food be prepared without partially hydrogenated vegetable oil” as cooking in this substance considerably raises the risks of heart disease!

 Where do these people come from?
