Despite the word "healthy" popping up on menus at the nation's largest fast food chains, researchers found that fast food restaurants have barely become more nutritious over the last 14 years. The findings are important because the food is being branded as healthy and Americans on average eat fast food quite frequently. The study, founded by the Robert Wood Johnson Foundation and published in the "American Journal of Medicine" found that fast food accounts for 15 percent of American's daily energy intake. The study did give credit where credit was due and tipped its hat to McDonalds for cutting the amount of fries in a Happy Meal and replacing them with apple slices.
