When I taught health care, trade off was one of the topics some students had difficulty getting a handle on. A while back I raised the question in a post regarding the “real” minimums for fat and protein…..not the recommended minimums that can be found on the back of a can in the grocery store. Let’s say I want a low fat diet. Maybe the recommended minimum is around 50 grams, but I have every intention of going below that. At what point am I putting myself in serious danger? Of course, one of the hard core facts of life is that it is full of trade offs. But, I agree with your point, wouldn’t it be nice if those people who are aware of the trade offs made a point of sharing them and not being so selective.
