Zinc plays a critical role in taste and smell through its involvement in gustin, a protein needed for healthy taste bud function. When Zinc levels are low, this process can be disrupted, leading to reduced or altered taste and smell, sometimes one of the earliest signs of deficiency.
This can impact appetite and overall nutrient intake, particularly in at-risk groups such as older adults or those with impaired absorption.
Restoring adequate zinc levels can often improve sensory function, but balance is key, as excessive intake may interfere with other minerals.
