When consuming a diet rich in lime juice, the action of ptyalin on starch is reduced.

Lime juice is acidic in nature due to the presence of citric acid. The acidic environment created by lime juice inhibits the activity of ptyalin, which is an enzyme responsible for the initial breakdown of starch into simpler sugars. Ptyalin functions optimally in a slightly alkaline or neutral pH range. Therefore, when lime juice, with its acidic properties, is introduced, it hinders the enzymatic action of ptyalin on starch, leading to a reduction in its effectiveness. Hence, the correct answer is option 2.
