The Truth About Taste Buds

Abstract

Taste perception is a complex process affected by many factors, including genetics, sex, age, and experience. Taste buds are the initial point of taste perception. Taste bud growth begins at the prenatal stage of development, and different cell types and regions of the tongue are sensitive to different flavors. For example, the greatest sensitivity to sweet is at the tip of the tongue, whereas the greatest sensitivity to sour is at the upper sides of the tongue. Eventually, babies begin to develop certain taste preferences and, as they age, genetic changes, such as allele expression, can cause individuals to be more sensitive to some flavors over others. This contributes to the differences observed in infant versus adult sensory perception. Similarly, the sex of a person can drastically vary their ability to detect certain basic traits. Aside from biological factors including age and sex, the environment also affects taste preferences and perception. This consists of race, ethnicity, culture, and location. The simple topic of taste buds is much more complex than anticipated and is important for humans to become more knowledgeable about something they use in their everyday lives.
