What Is the Nutritional Value of a Cucumber?

To maintain the nutritional value of a cucumber, choose one without soft spots or a large lump in the middle. These will have a diminished taste and lower nutrient content. Cucumbers can be refrigerated for up to 7 days. For organic cucumbers with no wax, it's best to maintain the moisture and nutrient content by wrapping them in plastic.
