Dehydration Prevention: Fruit Recommendations and Oral Rehydration Salts

In Brazil's Amazon region, extreme heat and humidity raise the risk of mild dehydration. The "Temporada das Frutas" campaign by Pátio Gourmet, with nutritionist Daniela Ward, highlights five water‑rich fruits—watermelon (about 92% water and lycopene), melon (water, potassium, vitamin C), pineapple (water, vitamin C, bromelain), orange (water, vitamin C, potassium) and coconut water (natural electrolytes)—as daily dietary aids, also noting the regional camu‑camu for its high vitamin C content.

In Portugal, World Health Organization guidelines promote oral rehydration salts (SRO) containing glucose, sodium and potassium to rapidly reverse acute dehydration caused by heat, diarrhea, vomiting or fever. The 2003 WHO formulation reduced particle concentration for better fluid absorption. World Oral Rehydration Day on 29 July underscores the life‑saving role of SRO in preventing severe dehydration.
