Cucumbers do have a significant number of calories in them, though they still provide a lot of nutritional value overall. In just one serving, the average cucumber has around 332 calories, 19.2 grams of which comes from fat. There are 6.4 grams of saturated fat in cucumbers and 1,654 mg of sodium.

The sodium content in cucumbers is mostly what prevents it from getting on the list of acceptable foods for most trendy diets, though they are still good for you as a whole. Most people that eat cucumbers tend to do so in moderation, as they are used in salads and side-dishes so the calories do not really accumulate.
