Final answer:
Copper deficiency can lead to a loss of taste perception, and to enhance flavor when olfactory sensation is lacking, substances like salt may be used to stimulate the gustatory sense.
Step-by-step explanation:
Loss of taste perception is a symptom of a deficiency of the trace mineral copper. When copper levels are low, certain enzymes that facilitate iron absorption and transport, and contribute to other bodily functions, are affected. This can lead to symptoms such as loss of appetite, hair loss, and importantly, diminished taste or smell, known as anosmia. To combat the decreased taste that can occur when olfactory sensation is not present to complement gustatory stimuli, foods must be seasoned with substances that can stimulate the taste buds, such as salt. Copper is essential not just for the taste perception but also for overall health, as it plays a role in the formation of hemoglobin, iron absorption, and transport.
