Why do "healthy" foods have to be so nasty?

As many of my friends and family know, I have been doing weight watchers for quite a while. I lost 20 lbs, and then fell off the wagon, and gained 15 back. I am now back to the program, and working hard to re lose those 15 lbs. Yesterday while I was at the pharmacy waiting for a prescription to be filled, I wandered down the "snack bar" isle. Now I am trying to get back into doing weight watchers, so I say to my self hmm these look good, Lets try them and see if they are any good. I get home, and I open the first one, Chocolate peanut butter cookie, and took a bite. Just sitting here and writing about it I can smell it, and taste it. it was absolutely NASTY! So I eat about half of it hoping that it will get better tasting as I go, no such luck. So I decide to try another one, a different brand, hoping for better results. Creamy peanut butter covered in chocolate, sounds promising, boy was I wrong! Cardboard, that is what it tasted like nothing but cardboard. needless to say both of the "health bars" went into the trash. As I thought about it I had to wonder How in the world do these companies sell this stuff? Obviously the people that continue to purchase them either have no taste buds, or...well I can't really think of an or, but my question is still Why do they have to taste so nasty? Why does "healthy food" in general have to be so bad tasting? My thought is that they make it taste bad so you wont eat more than you should, and that is why it is so healthy for you. In my family we have a problem with Gluten, so we made substitutes. When we started out more than ten years ago the food we had available to us was nasty, but we were not satisfied with just eating the nasty food, we wanted good food. we wanted food that we could all eat, and not have to make two dinners the nasty one for who ever has Celiac and the good one for the rest of us. So why can't the snack bars that are supposed to be healthy for you be good as well as healthy? Can you tell me that?
