When Sweet Things Taste Bitter?

A bitter or bad taste in the mouth can be a normal reaction to eating pungent or sour foods. However, when the taste lasts for a long time or happens unexpectedly, it can be concerning. Taste is a complex sense that can be affected by many factors, including poor dental hygiene, dry mouth, or pregnancy.

Why does sweet taste bitter?

Activation of the sweet taste receptors T1R2 and T1R3 by a sweet substance induces the activation of signaling proteins residing within the cell, namely: α-gustducin, PLC-β2, IP3R and TRPM5 [13]. Interestingly, scientists discovered that the same repertoire of signaling proteins is required for bitter taste perception.

What can cause a sudden change in taste?

Taste bud changes can occur naturally as we age or may be caused by an underlying medical condition. Viral and bacterial illnesses of the upper respiratory system are a common cause of loss of taste. In addition, many commonly prescribed medications can also lead to a change in the function of the taste buds.
