Taste test reveals insect protein bars outpace cereal bars in curiosity and preference

A small Portuguese study measured brain activity and heart rate of 38 adults tasting an insect protein bar and a cereal bar, finding higher curiosity and attentiveness during the insect-bar tasting, and a majority preferred the insect bar—suggesting exposure may reduce disgust toward insect-based foods and boost openness to sustainable protein sources; results are preliminary and based on a limited sample.
