Staying Hydrated During Cancer Treatment: Foods That Can Help
Hydration is crucial for everyone, but it becomes even more important when you’re undergoing cancer treatment. Treatments like chemotherapy, radiation, or certain medications can lead to dehydration through side effects like nausea, vomiting, diarrhea, or simply a lack of appetite. While drinking plenty of water is essential, eating foods that are high in water content can also help you stay hydrated and keep your body functioning at its best.
If drinking large amounts of water feels overwhelming—or you’re looking for creative ways to stay hydrated—this blog will guide you through foods that can help boost hydration while supporting your overall nutrition.
Why Hydration Is So Important During Cancer Treatment
When you’re hydrated, your body is better equipped to:
Flush out toxins, including the byproducts of treatments like chemotherapy.
Support kidney and liver function, which play a critical role during cancer treatment.
Maintain energy levels and reduce fatigue.
Keep your skin, joints, and digestive system functioning properly.
Cancer treatments often make it harder for your body to retain fluids, and side effects like dry mouth or nausea can make drinking water less appealing. Incorporating hydrating foods into your meals is an easy and effective way to make sure you’re getting enough fluids.
Foods That Hydrate and Nourish
Here’s a list of hydrating, nutrient-packed foods to consider adding to your diet:
Cucumbers: Cucumbers are over 95% water, making them one of the most hydrating vegetables you can eat. They’re also light and refreshing, which can be helpful if you’re experiencing nausea or a reduced appetite. Try slicing cucumbers into salads, blending them into smoothies, or snacking on them with a bit of hummus or a yogurt-based dip.
Watermelon: True to its name, watermelon is about 92% water. It’s naturally sweet and easy to digest, making it a great option if you’re dealing with treatment-related side effects. Watermelon also contains vitamins A, C, and antioxidants that support your overall health. You can enjoy it on its own, toss it into fruit salads, or freeze it for a refreshing snack.
Zucchini: Zucchini, like cucumbers, is high in water content—about 94%. It’s also rich in potassium, which helps balance your electrolytes and can reduce the risk of dehydration. You can roast zucchini, it into zoodles, or include it in soups and casseroles.
Oranges and Citrus Fruits: Oranges, grapefruits, and other citrus fruits are around 88% water and packed with vitamin C, which can support your immune system. Their natural sweetness and juiciness can also be a good way to stay hydrated. If eating citrus fruits whole is challenging due to mouth sores or sensitivity, try blending them into smoothies or juicing them for a refreshing drink.
Berries: Strawberries, blueberries, raspberries, and blackberries are hydrating and loaded with antioxidants, vitamins, and fiber. Strawberries, in particular, are about 91% water. Add berries to oatmeal, yogurt, or smoothies for a hydrating and nutrient-rich snack.
Soups and Broths: Soups, stews, and broths are an excellent way to hydrate, especially if drinking water feels challenging. Look for low-sodium broths or make your own at home to avoid excessive salt, which can contribute to dehydration. Add hydrating vegetables like celery, carrots, and zucchini to your soup for an extra boost.
Tomatoes: Tomatoes are about 94% water and are versatile enough to incorporate into many meals. They’re also a great source of antioxidants like lycopene, which may have cancer-fighting properties. Enjoy tomatoes raw in salads, roasted, or blended into sauces or soups.
Leafy Greens: Spinach, lettuce, kale, and other leafy greens are high in water and packed with vitamins and minerals. Spinach, for instance, is about 91% water. Add leafy greens to salads, smoothies, or sandwiches for an easy way to stay hydrated.
Apples and Pears: Both apples and pears are around 85% water and contain fiber, which can help support digestion. If chewing is difficult, try baking apples or pears for a soft, hydrating dessert option.
Yogurt: Yogurt, especially plain or low-sugar varieties, is a hydrating food that also provides protein and probiotics to support gut health. Pair yogurt with hydrating fruits like berries or cucumbers for a double dose of hydration.
Tips for Staying Hydrated
Snack Smart: Keep cut-up fruits and veggies like cucumbers, watermelon, or oranges in the fridge for quick and easy snacks.
Blend It: Smoothies made with hydrating fruits, leafy greens, and a base like water or coconut water can be both refreshing and nutrient-rich.
Infuse Water: If plain water doesn’t appeal to you, add slices of citrus fruits, cucumber, or fresh mint to infuse flavor.
Listen to Your Body: Pay attention to signs of dehydration, such as dry mouth, dark urine, or fatigue, and aim to drink and eat hydrating foods throughout the day.
Working With Your Care Team
While hydrating foods can help, it’s important to talk to your care team about your specific hydration needs. They can provide personalized recommendations based on your treatment plan and any side effects you may be experiencing.
By focusing on hydrating foods and staying mindful of your fluid intake, you can better support your body during cancer treatment. Small, simple changes can go a long way in helping you feel stronger and more energized.
