Taste buds are tiny sensors on your tongue that help you enjoy flavors. They play a crucial role in how you experience food and drinks. Did you know that humans have about 2,000 to 8,000 taste buds? These little guys are responsible for detecting sweet, salty, sour, bitter, and umami flavors. Each taste bud contains 50 to 100 taste receptor cells, which send signals to your brain to identify different tastes. Interestingly, taste buds aren't just on your tongue; they can also be found on the roof of your mouth and even in your throat. They regenerate every one to two weeks, which is why your sense of taste can change over time. Ever noticed how some foods taste different when you have a cold? That's because taste buds work closely with your sense of smell to create the full flavor experience.
