Of course, your tongue will chew, swallow, taste, and then wonder how delicious (or not!) the food was. But your tongue can do much more, including providing snapshots of your overall health.
Symptoms of many chronic and acute diseases appear on your tongue. In fact, sometimes they are one of the first signs that something is wrong.

Some people describe it as the consistency of cottage cheese.
