    1. Eat less sugary food. REASON: sugary food usually contain high amount of glucose or starch. Starch will be directly broken down to amylose(check it, i'm not sure!) by amylase. Both glucose and (amylose) are food for bacteria and promote bacterial growth in mouth. Destruction to teeth.

    Eat less acidic food. REASON: the acidic food debris erodes the enamel by increasing the acidity inside mouth cavity

    2. starch in rice is broken down to amylose by amylase in saliva, giving the sweet taste.
