How many calories are in 6 ounces of plain tea?

Here's why:

* Tea itself is very low in calories: The main components of tea are water, polyphenols (antioxidants), and small amounts of caffeine. These compounds contribute very few calories.

* The volume matters: 6 ounces is a relatively small amount of liquid.

Therefore, 6 ounces of plain tea would likely contain less than 5 calories.
