Puffed and extruded snacks are experiencing a renaissance. There are many different types of snacks in this category for shoppers to choose from, including traditional, healthier and even “free-from” options like gluten-free. Whole grains are getting in on the action, including specialty grains like quinoa. Pulses, legumes and vegetables also go into the mix. And every primary product category within this salty snack format—from cheese snacks to pork rinds—is experiencing growth.
