Cucumber Nutrition Benefits and Facts

Nutritional summary

Cucumbers are a staple component of the Mediterranean diet, which is well-established by systematic reviews to reduce the risk of type 2 diabetes and support cognitive function in older adults .
Because they are primarily composed of water, cucumbers are a low-energy-density food, providing very few calories per cup while contributing to daily hydration .
The nutritional profile of cucumbers can vary significantly based on cultivation methods; for example, those grown in natural soil may take up a wider range of micronutrients compared to those grown in hydroponic (soil-less) systems optimized solely for yield .
Early research indicates that cucumber juice may have a beneficial effect on blood pressure in hypertensive patients, though more robust clinical trials are needed to confirm these specific therapeutic effects .

Interesting fact

Botanically classified as a fruit, the cucumber is a member of the same family as watermelons and pumpkins.
