Should You Eat Cucumber Skin?
- Skin adds Vitamin K and fiber — most of the nutritional content is concentrated in and just under the skin
- Calories saved by peeling: only 2 calories per cup — not worth the nutritional trade-off
- Waxed cucumbers sold in stores should be washed well or peeled since the wax coating can trap residues
- English/Persian cucumbers have thinner, less bitter skin — ideal for eating unpeeled
