As we age, changes in our sense of taste can significantly impact our health. The human taste system recognizes five basic tastes: sweet, salty, sour, bitter, and umami through taste buds on our tongue.
Recent research shows that sensitivity to salty and bitter tastes notably decreases with age. Interestingly, this change isn't simply due to a reduction in taste bud cells. Other factors, including hormonal balance and brain function changes, may play crucial roles.
For example, the hormone angiotensin II, which regulates blood pressure, can affect how we perceive saltiness. This finding could lead to new methods for improving elderly nutrition.
Future research may reveal ways to help older adults maintain an enjoyable and healthy diet despite age-related taste changes.
