Look for some new “healthy” snack bars on the shelves of local stores this summer from candy companies trying to steal market share from brands like Kind and Clif. At an industry trade show last week, Hershey debuted a line of snack bars under its high-end Brookside brand (with see-through packaging to show off the fruit and nut pieces), while Mars showed its own line of Goodnessknows Snack Squares (with bite-sized sections for portion control). All the bars incorporate fruit, nuts, oats, seeds and dark chocolate, with serving sizes below 200 calories and no artificial flavors. Whether they’re really “healthy” is debatable, but they’re clearly designed to get the attention of shoppers who typically skip the candy aisle. Major marketing campaigns are on the way.
