Chewing is a basic function that we do day in/day out. It not only is important for food breakdown and digestion, but also has the potential to improve our attention, stress and moods.
According to a systematic review that 'inspected the attributes of effects on attention in studies investigating the effects of chewing on attention or alertness conducted with pre-post design in healthy subjects, except elderly', 'positive attributes of effects of chewing on attention, especially on sustained attention, were shown in over half of the reports. These effects also appeared with improvement in mood and stress relief and were influenced by time-on-task effect.'
