Crunch is associated with freshness like leaf & vegetables eaten by prehistoric humans. Crunch activates nerve endings in the mouth, sending signals to the brain that contribute to pleasure. The sound of crunching adds an auditory dimension to eating, which can enhance enjoyment. Commercial food companies meticulously design the "perfect crunch" using science to maximize consumer appeal. The result? Snacks designed for addictive consumption, often high in calories, unhealthy fats, and sugars make these snacks highly palatable.

That irresistible crunch? It's a calculated move by food giants, not a happy accident.
