That would, most likely, depend upon how you lost your sense of taste in the first place. The sense of smell and taste are intimately linked. Have you ever held your nose to eat something you did not like? Anything negatively affecting smell can therefore have an impact on taste. It would stand to reason that restoring smell could restore taste. Allergies, colds and aging all can affect our sense of taste. It is not at all uncommon for our sense of taste to diminish in our 60s and beyond. This may explain why the seniors in my neighborhood had all the good candy when I was little. Although aging is the primary cause of impaired taste or smell, various medical conditions can also play a role. Diabetes, nasal and sinus disorders, viral infection of the upper respiratory tract, head trauma, zinc deficiency, exposure to toxic chemicals, lesions of the tongue, and various drugs can all have a negative impact on our sense of smell and taste. Improvements in these conditions can allow our sense of taste to improve. If you have not already spoken with your doctor regarding the loss of taste, please do so.
