People want to eat healthy. So, if you sell a candy that is almost pure sugar, you advertise it as “Zero Trans Fat”. If you are selling pasta and cheese and pepperoni, you sell it as a salad. Maybe you sell your candy as fruit chews – sounds much better!
The best way to not fall for any of these marketing ploys is to read the labels. Does the “Reduced Fat” version even have fewer calories than the “Regular” version? Just because it has the word “Healthy” in the label doesn’t mean it really is healthy – buyers beware!
