Moderation is indeed the key. This trans-fat issue is no doubt the current big health trend. It's a good one: personally I've been aware of trans fat for several years now--well before it became front-page news--and have made an effort to limit or outright avoid it where practical. But you gotta wonder if their being phased out will make people lose sight of overall good dietary practices. Trans fat or no, moderation in all fats and oils is still the way to go. Also (and I'm not entirely clear on this) I've read that the high temperatures used in the deep-frying you see with fast food tend to "denature" oil somewhat, making the oil more unhealthful than it otherwise would have been. Which basically means it's still a good idea to moderate the fried foods.
