A US national survey shows fast food accounted for 11% of daily caloric intake in 2007-2010.

Fast food providers have been adding salads, yogurt, etc. to try to encourage eaters to come there to eat.

But as menus have grown many of the choices grew in size, calories, and sodium.

According to a study in the Journal of the Academy of Nutrition and Dietetics, even with lighter items in the mix, fast food menus are less healthy than they were 30 years ago.

"These results demonstrate broadly detrimental changes in fast-food restaurant offerings over a 30-year span including increasing variety, portion size, energy, and sodium content. Research is needed to identify effective strategies that may help consumers reduce energy intake from fast-food restaurants as part of measures to improve dietary-related health issues in the United States."

This article mentions and has data for several ways things have gotten worse:

Entrees: Bulging portions at the heart of the meal

Desserts: More than just a little something sweet

Sides: Adding those extras adds up

"Consumed together as a single meal, the study found, the average entree and side account for nearly 40 percent of a 2,000-calorie daily diet."
