The watch words below are a guide. Still, food items can be very healthy or unhealthy regardless of the use of any of these words. For example, "fat free" food is often packed with sugar and calories to get it to taste better. There are times when these words are used to mislead you (which is why we call them "watch words" and not guarantees). So use this along with your good judgment to steer clear of the bad stuff. More often than not, you’ll end up making a smart decision.
Good luck and keep your eyes open.
