I’ve recently come to the realization that when I’m feeling sluggish and tired, it’s often because I’m actually dehydrated. It usually happens around that 2 pm slump at work, when I’ve forgotten to refill my water bottle and reach for a coffee instead.

Did you know that when you feel thirsty, you’ve already lost 1-2% of your body fluid, which makes you lethargic? In fact, dehydration can lower blood volume, meaning you don’t get as much blood to your brain and your heart has to pump harder.

Okay, science class dismissed, and now the real question is: What else can we do about it besides drinking more water?

Since I for one find snacking to be more fun sometimes, I’m really interested in which fruits and vegetables do double duty in giving our bodies major doses of nutrition and hydration.

Scroll on for the 10 best hydrating foods and our favorite recipes for using them. Hint: these all have the bonus quality of being low-calorie because, well, water.
