Actually most national brands no longer are made with lard. Rosarita beans are the ones I have in my pantry right now and they do not contain lard. Read the labels if you're uncertain.
Lard in and of itself is not unhealthy either. People tend to say "lard" in the same tone of voice they'd say "dog poop" ... and I'm not sure most people even think about why they are having a knee jerk reaction to the word. Lard is nothing more than pig fat. Have you ever used bacon drippings in your cooking? Then you've used a type of lard. The worst thing about lard is that it's high in saturated fats, something that most of us (especially those on a diet) want to avoid.
Honestly, whenever I hear "I've read that ... " I tend to have a bit of a reaction myself.
I think it's important to think about WHERE you read or heard whatever it is you heard. Especially when it's something as generic and open ended as "X is unhealthy." If someone makes a blanket statement w/out any supporting evidence, then I tend to dismiss it pretty much instantly.
Anything can be "unhealthy" if you want to make a case for it. Living is unhealthy - after all, the end result of life is ... death.
