How Fast Is Jaw Chewing?

Chewing moves the jaw at about 20 cm per second in steady rhythm — roughly 1 cycle per second. The average mouthful gets about 20 chews before swallowing, though most people grossly underestimate this.

Most people chew roughly 20 times per mouthful — far less than they would guess.
