The article argues that gum is not a unique or preferred way to activate the frontal lobe because other practices can do so without the stated downsides. The article attributes gum's cognitive effect to jaw proprioceptive signals stimulating the frontal lobe.

The article claims chewing without food can contribute over time to ulcers and digestive dysfunction.
