Much has changed in the past 17 years, but one thing that remains the same is the unhealthfulness of fast food. HealthDay reports on a study conducted at the Department of Agriculture’s Cardiovascular Nutrition Laboratory, that looked at the nutrition of fries, cheeseburgers, grilled chicken sandwiches and regular cola served at fast food restaurants from 1996 to 2013. The researchers focused on 27 items, including small, medium and large fries and cola beverages, a grilled chicken sandwich, and 2-ounce and 4-ounce cheeseburgers. Ready? The envelope please….The researchers found that the average calorie content, salt content and saturated fat content of these items stayed more or less the same over the 17-year period.
