Not only to fight obesity, but other dietary medical conditions as well.  Usually if a restaurant puts it up, they are not afraid of the contents in their food.  The loudest protestors are usally the ones that have something to hide.

I sincerely support this idea, a few days ago there was a post about food markets doing something similar by posting banners directing people to healthy foods. I do agree that while most know which foods are healthy and which ones are not, we still make bad choices mainly because we are, unfortunately, led by our taste buds. But supposing that nutritional facts are in fact displayed in menus, next time you're about to order those fries there's a greater chance that the realization of how unhealthy they are will dawn on you before you order them. It'll just be a constant reminder to those who have a better grasp of what healthy eating is, and it will educate those who are not informed.

 

I think it should be enforced it would make a difference in choice. I know that I have asked before for there nutrition fact menus and a few times they were not available. But I think all food should be labeled with its nutrition values.

I went into a Apple Bees last year and they participated in the Weight Watchers menu.  It was great to see the numbers and what I was eating.  I did make healthier choices.  I wish more restaurants would do that.  It would keep me on the straight and narrow more.
