Two common kinds of cucumbers grown in the U.S. include slicing and pickling. Slicing cucumbers are usually large with a thick skin, while pickling cucumbers are smaller with a thin skin.

4. What's in a Pickle?

Pickles are cucumbers that have been soaked in a brining solution made of salt, vinegar, and water.

A half-cup of sliced cucumbers has 8 calories and more than 10% of the recommended daily intake of vitamin K.

6. Watery Wonder

A cucumber is more than 95% water.

7. Soothes the Eyes

Cucumber slices over the eyes may help reduce puffiness, thanks to the fruit’s water content and caffeic acid.
