Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Oranges and orange juice are commonly recommended for mild dehydration, particularly due to their natural electrolyte content and high water percentage. Scientific evidence supports the use of fluids containing both water and electrolytes in treating dehydration. Oranges provide not only water (they are about 87% water by weight) but also a significant amount of potassium, an essential electrolyte often lost during dehydration. Additionally, orange juice contains small amounts of sodium, magnesium, and other electrolytes that help restore fluid balance.

The World Health Organization’s Oral Rehydration Solution (ORS) is the gold standard for dehydration; it relies on a specific balance of glucose and salts. While orange juice is not a replacement for ORS or intravenous fluids in cases of severe dehydration, it can be helpful for mild dehydration or as a supplementary fluid. Several clinical studies have shown that fruit juices (including orange juice) can aid in rehydration in children and adults, though caution is advised in cases of gastroenteritis, as high sugar content could potentially worsen diarrhea.

Historically, orange juice has been used to rehydrate and provide nutrition during illness. Modern guidelines recommend diluted juice if used for rehydration, especially in children. In summary, while oranges are not a substitute for medical-grade rehydration fluids, there is moderate scientific support for their use as a hydrating and electrolyte-replenishing beverage in mild dehydration.
