Staying hydrated is always important, but especially during cancer treatment, when nausea and other side effects can leave you (literally!) sapped. Plenty of juicy foods—such as watermelon and cucumber—can help you keep up your fluid levels.

1. Cucumbers

At 95 percent water content, a cup of cucumber slices can be nearly as thirst-quenching as a glass of water. Cucumbers also provide a little fiber and some vitamin C (about 6 percent of the Daily Value per cup). Don’t limit your cucumber consumption to tossing slices into green salads; get inspired to make refreshing cucumber recipes: try a cooling cucumber-yogurt dip or cucumber-and-tomato-based tabbouleh.

2. Salad greens

Part of the reason that a 2-cup serving of salad greens has fewer than 15 calories is that greens are more than 90 percent water. They are also packed with nutrients, such as folate, vitamin C, fiber and the antioxidant beta carotene, which helps keep your eyes and skin healthy. Plus, having a salad for lunch (or dinner) is a great way to bang out a couple of veggie servings.

3. Strawberries

Strawberries deliver the most vitamin C of all berries and also provide folate, a B vitamin that’s essential for the healthy growth of new cells. And, since they’re 91 percent water, they’ll contribute significantly toward your overall fluid intake. Eat them straight up or try them in a new strawberry recipe: they’re special in everything from salads to baked goods.

4. Watermelon

At 92 percent water (hence the name), watermelon is a good source of vitamin C and, when it’s red (some are orange or yellow), it also has lycopene, an antioxidant that may help protect against heart disease and some types of cancer. Enjoy fresh wedges (go ahead and see how far you can spit the seeds) or, better yet, get creative with watermelon recipes.

5. Yogurt

Depending on your preferred type, regular plain yogurt is 85 to 88 percent water (surprisingly, there’s more water in fuller-fat yogurt). You’ll also get calcium and some B vitamins (namely B12 and riboflavin). To be sure you’re getting some good-for-you probiotics, look for a yogurt that carries the “Live & Active Cultures” seal.

6. Papaya

At 88 percent water, this fruit can help you stay hydrated. But it also gives you a dose of fiber—1 cup delivers 3 grams.

7. Butternut squash

This sweet and nutty squash is 88 percent water. A cup of cooked butternut squash also boasts over 400 percent of your Daily Value for vitamin A—a key nutrient for eye health—as well as healthy doses of vitamin C, potassium and manganese.
