Are crickets the new food craze?

The Exo and Chapul snack bars each contain up to 40 dried, ground crickets. According to manufactures, cricket flour has two times more protein than beef and 15 percent more iron than spinach. 

"We thaw them out, we rinse them, we throw them on the sheets, we cook them, and mill them down to a flour that goes into our energy bars," said Pat Crowley with Chapul Revolution. 

Consumer Reports did a blind taste test of six bars and cookies from two manufacturers. 

"For the most part the bars have pretty straight forward ingredient listings with things like fruits, nuts, honey, flax, and of course, crickets," said Amy Keating, a nutritionist with Consumer Reports. 

The taste testers noted the bars tasted more like coconut than crickets. 

Because crickets are closely related to shrimp, manufactures warn those with shellfish allergies to avoid products containing cricket flour.
