how is this possible?
Why does our sense of taste differ from person to person?
Our sense of taste is highly connected to our sense of smell. If you think about the last time you had a cold and stuffy nose, you might remember that your food just didn't taste as it usually does. Therefore one reason that our sense of taste varies is that people have different abilities to smell odors.
Also, the tongue has specific areas that are sensitive to the basic flavors, and scientists have even discovered that there are taste buds that go beyond the basic sweet, salt, sour, and bitter. The distribution and abundance of these nerve endings, along with how you chew and swallow, might also contribute to diversity in how the sense of taste is perceived.
Sense of taste is determined by your tastebuds. Just as other physical characteristics are inherited, so too are your tastebuds. Sense of taste is also, at least partially, a result of training - we can learn to like certain flavors, although not always. So this is a complex coordinated effort between physical attributes and behavior.
