In a couple of contexts, most recently Alton Brown's Good Eats show on tamales, I've heard it said that lard isn't actually the cardiovascular nuclear bomb that it's been made out to be.
Brown's claims, for example, are that lard is lower in saturated fat than butter and equivalent to (I think) sunflower oil in monunsaturated fats. Also, no trans fats.
Are people omitting some dark side to lard when making such points? If not, when and how did lard get its reputation?
