One cup of sliced cucumbers has about 1.7 grams of sugar; peel, size, and water content shift the number slightly.
Crisp, cool, and light on carbs, cucumbers are a go-to when you want crunch without much sweetness. Still, many people want a simple answer to a simple question: how much sugar in cucumbers? This guide gives you clear numbers, quick tables, and smart serving tips, so you can build plates that fit your goals.
How Much Sugar In Cucumbers? Serving Sizes And Basics
Most raw cucumbers sit in a narrow range for natural sugars. A standard cup of slices (about 104 grams) lands near 1.7 grams of total sugar. Per 100 grams, the value is similar. Peel removal nudges the total down a hair, while variety and seed size can nudge it up or down a touch. The big headline: cucumbers are low in sugar compared with fruits and starchy vegetables.
At-A-Glance Sugar Numbers
The table below gathers common forms and portions. Values are rounded to keep planning simple.
| Form Or Portion | Total Sugar (g) | Notes |
|---|---|---|
| 1 cup slices, with peel (~104 g) | ~1.7 | Typical salad portion; based on USDA-derived data |
| 100 g, with peel | ~1.7 | Good for recipe scaling |
| 1 cup slices, peeled | ~1.6 | Peeled trims a small amount |
| 1/2 cup slices | ~0.85 | Handy snack size |
| 1 medium piece (7–8 in, ~150 g) | ~2.5 | Whole snacking cucumber |
| 1 spear (about 50 g) | ~0.85 | Common pickle spear size, but raw |
| English/seedless, 1 cup | ~1.6–1.8 | Similar to common slicing types |
What Drives Sugar In A Cucumber
Three things set the number you see on a label or nutrient table.
Water Content
Cucumbers are mostly water. That high water share dilutes natural sugars in the flesh. Skin-on slices tend to hold shape and moisture, which keeps sugar per cup steady.
Peel And Seeds
Peeling trims a bit of sugar and fiber along with trace nutrients. Big seed cavities can shift weight without adding sugar, so seed size can change the sugar per cup slightly.
Portion Choice
Sugar adds up with bigger servings. If you’re tracking tight, measure by cups or grams, then season and plate for flavor.
How Cucumbers Compare To Other Crunchy Produce
Not all crunch behaves the same. A cup of cucumber brings a tiny hit of natural sugar, while sweet bell pepper, carrots, and cherry tomatoes land higher. That’s why cucumber sticks work well when you want volume and hydration without much sweetness. Dietitians group cucumbers with non-starchy vegetables, a bucket that’s low in carbs and fits most glucose goals.
Why Cucumbers Are Handy For Blood Sugar
Low sugar and low total carbs help keep spikes tame. The skin adds a little fiber. The water helps with fullness. Pair slices with protein or a rich dip and you get a smart snack that stays satisfying.
Trusted Numbers And Where They Come From
For a reliable one-cup value, nutrition compilers that pull from USDA show about 1.7 grams of sugars in raw, sliced cucumbers with peel. Hospital nutrition libraries list peeled slices near 1.6 grams per cup. Both sit in the same low zone, which is what you’ll taste on the plate—crisp, fresh, and barely sweet.

Using Cucumbers When You Track Sugar
Here’s how to fit cucumbers into low-sugar eating without giving up flavor.
Pick Portions That Match Your Meal
Salad night? Budget 1 to 2 cups. Snack plate? Half a cup to one cup with a protein spread or cheese. Sandwich? Go by slices so you can stack to taste.
Keep The Peel When You Can
The peel offers crunch and a touch more fiber. Rinse, pat dry, and slice thin. If texture is a deal-breaker, peel in stripes to keep some skin on every slice.
Salt, Acid, Fat, Heat: Flavor Rules That Work
A pinch of salt wakes up the fresh taste. A squeeze of lemon or a splash of vinegar brightens everything. A small glug of olive oil adds body. Red chile flakes or cracked pepper bring a little heat. With those four moves, you get a plate that tastes bigger than its sugar tally.
Smart Pairings For Steady Energy
Match cucumbers with grilled chicken, tuna, hummus, Greek yogurt dip, or eggs. That mix of protein and fat slows digestion, so the small amount of sugar hits gently.
Table Of Handy Conversions
Use these quick conversions when you’re logging or adjusting a recipe. Values reflect raw cucumbers and round to keep math friendly.
| Portion | Approx. Sugar (g) | Tip |
|---|---|---|
| 5 thin slices (sandwich) | ~0.4 | Layer with turkey and mustard |
| 10 thin slices | ~0.8 | Great for a snack plate |
| 1 heaping cup chopped | ~2.0 | Nice for salsa or salads |
| 1 small cucumber (6–7 in) | ~1.7 | Eat out of hand |
| 1 large cucumber (8–9 in) | ~2.7 | Split across two meals |
| 1/4 English cucumber | ~0.9 | Slice into ribbons |
| 1 cup diced, peeled | ~1.6 | Mild bite; easy on texture |
Label Reading Tips For Cucumbers And Pickles
Fresh cucumbers don’t list added sugar on produce stickers. The place to scan is the dressing bottle or the pickle jar. On jars, look at the ingredient list: words like sugar, honey, corn syrup, or dextrose signal a sweet brine. The Nutrition Facts panel shows “Added Sugars”; dill styles often read 0 g, while sweet styles can jump. If you want a tangy spear without sweetness, pick “dill,” “kosher dill,” or “no sugar added” lines.
When Using Dressings
Creamy ranch, honey mustard, and sweet vinaigrettes can add far more sugar than the cucumber itself. Two spoonfuls of a sweet dressing can outpace the 1.7 grams in a whole cup of slices. Mix olive oil with lemon, or whisk yogurt with garlic and herbs for zip without extra sugar.
Clear Answers To Common Questions
Do Pickles Change The Sugar Story?
Dill pickles often add almost no sugar; they’re brined in salt, water, and spices. Bread-and-butter styles add sugar to the brine, so their slices can be sweet. Check labels when buying jars. Homemade gives you full control of sweetness.
Do Cucumbers Have Added Sugar?
No. Fresh cucumbers contain only natural sugars. Any added sugar would come from dressings, marinades, or pickle brines.
What About Net Carbs?
Per cup, carbs sit around 3.8 grams, with about half a gram of fiber. Net carbs (carbs minus fiber) land near 3.3 grams per cup. That keeps cucumbers squarely in the low-carb lane.
Make Low-Sugar Plates With More Flavor
Salad Ideas
Slice cucumbers thin and toss with cherry tomatoes, red onion, herbs, lemon, and a spoon of olive oil. Add feta or chickpeas for a fuller meal.
Snack Ideas
Cut into spears and serve with tzatziki, hummus, or nut butter. Sprinkle with everything seasoning or sumac for a quick lift.
Cooked Uses
Stir into cold soups, lay ribbons over grilled fish, or add late to a quick sauté so they stay crisp-tender.
Method Notes
Numbers in this guide reflect raw cucumbers measured by common kitchen volumes and by grams. Rounding keeps the tables readable. Source pages reflect lab-based nutrient databases built from USDA data and professional dietetic guidance. Serving weights reflect trimmed ends and normal water loss after rinsing and pat-drying at home accurately.
Bottom Line
When you ask “how much sugar in cucumbers?”, the short take is clear: a cup of raw slices sits near 1.7 grams, and even a full medium cucumber barely breaks into the twos. That makes cucumbers a handy base for low-sugar salads, snacks, and sides.
