What changes the calories
- Peeling a cucumber removes the skin, which slightly changes the fiber and nutrient content, though the calorie difference is small.
- Dressings, dips and oils add far more calories than the cucumber itself, so a cucumber salad can be much higher in calories than plain slices.
- Pickling usually adds sodium, and sweet pickles also add sugar, so pickled cucumbers can differ from raw ones.
- Cucumber size varies a lot, so a 'whole cucumber' from your store may weigh more or less than the 301 g reference.
Tips for logging it accurately
- Weigh your cucumber or slices on a kitchen scale for the most accurate entry, since sizes vary widely.
- Log dressings, dips, tzatziki or oil separately, as they usually contribute most of the calories in a cucumber dish.
- In BerryFit, you can snap a photo of your salad or snack plate to log the cucumber along with everything else on it.
