Rating (out of 5): 2

Cucumber (Cucumis sativus) is often recommended as a supportive food for hydration. This use is backed by scientific reasoning, though not by high-level clinical trials. Cucumbers are composed of about 95-96% water, making them one of the most water-rich vegetables. Consuming cucumbers can contribute to daily fluid intake, which is essential for preventing or managing mild dehydration. In addition to water, cucumbers also supply small amounts of electrolytes, such as potassium and magnesium, which are important for fluid balance in the body. However, the direct evidence supporting cucumber as a treatment for clinical dehydration is limited; no major clinical studies have assessed cucumbers alone for dehydration recovery compared to oral rehydration solutions or water. Most recommendations are based on their water content rather than unique rehydrating properties. Historically, cucumbers have been used in various cultures as a refreshing, cooling food, but their use specifically as a rehydration therapy is not well documented in traditional medicine. Thus, while scientific reasoning supports cucumber as a hydrating food, its role is adjunctive rather than primary in treating dehydration. For significant dehydration, especially with electrolyte loss, medical rehydration solutions are preferred. In summary, cucumber can help support hydration as part of a healthy diet, but should not be relied upon as the sole or main treatment for dehydration.
