The mini cucumber, often enjoyed with its skin intact, presents an exceptional profile of hydration and minimal caloric density. This approximately 35-gram portion, representing half of a standard mini cucumber, contributes merely around 5 kilocalories (kcal) to your daily intake, making it an excellent choice for volume eating and satiety without significant energy cost.

From a macronutrient perspective, this serving is predominantly water, offering about 33 grams of pure hydration (over 95% water by weight). The remaining caloric input comes almost exclusively from carbohydrates, totaling approximately 1.3 grams. Crucially, a meaningful portion of these carbohydrates —approximately 0.5 grams—is dietary fiber. Fiber intake, even in small amounts like this, contributes significantly to gastrointestinal motility and aids in blood sugar regulation, slowing down the absorption of the minor quantity of natural sugars present (about 0.6 grams). The net carbohydrate count remains impressively low, typically below 0.8 grams, making it highly suitable for ketogenic or low-carb dietary strategies.

While not a primary source of protein or fats (contributing less than 0.3 grams of protein and negligible fat), the cucumber provides valuable micronutrients. It is a source of Vitamin K, essential for blood clotting and bone health, providing a small but measurable contribution (around 5.7 micrograms). Furthermore, it offers trace elements like Potassium (about 51 milligrams), which is vital for fluid balance and nerve signaling, and Vitamin C (about 1.0 milligram), an antioxidant that supports immune function and collagen synthesis. Its exceptionally low sodium (under 1 milligram) and zero cholesterol content further cement its status as a heart-healthy, refreshing dietary staple, perfect for salads, snacks, or infused water. The phytonutrients contained in the skin, such as cucurbitacins and flavonoids, also possess potential anti-inflammatory benefits, underscoring the importance of consuming this food unpeeled for maximum nutritional benefit.
