Staying sufficiently hydrated is crucial to sustaining life, especially during nephrotoxic chemotherapy. However, thirst alone is not always enough to indicate how much fluid we need to consume. Underhydration is a persistent issue for many individuals, especially cancer patients who require extra care to ensure adequate hydration. While many may require additional IV hydration, incorporating hydrating foods in your summer diet can also be an excellent idea. Here are some favorite summertime hydrating foods that can keep you refreshed and hydrated. 

Watermelon: With a water content of 92%, watermelon is a refreshing and delicious way to stay hydrated. It's also packed with vitamins C and A, as well as magnesium.

Cucumber: This crunchy vegetable is a hydrating powerhouse with a water content of 96%. Keep the skin on for an added boost of gut-friendly fiber.

Lettuce: Add a base of lettuce to your salad and boost your hydration levels. Romaine lettuce, with a water content of 95%, is a perfect way to sneak some extra water into your system.

Tomatoes: These juicy fruits are a great addition to salads and contain a similar water content to lettuce. They're packed with important minerals like potassium, which you lose when you sweat, as well as other essential vitamins and minerals.

Strawberries: This fiber-filled fruit is made up of 91% water and is loaded with vitamins, minerals, and antioxidants.

Peaches: These juicy fruits have a water content of around 90%. They're perfect in a yogurt bowl, but try freezing fresh peaches and dropping them into sparkling water for the ultimate hydration-boosting beverage.

Oranges: Not only are oranges a great source of vitamin C, but they also have a water content of 86%. Starting your day with a glass of fresh-squeezed OJ can be a refreshing way to stay hydrated.
