When you're truly parched, a tall glass of water really can't be beat. But water's not the only place where we get our hydration -- turns out, high water-volume foods can also provide our body with fluids.
In fact, fruits and vegetables are composed of 90 percent water, said Roberta Anding, a spokesperson for the Academy of Nutrition and Dietetics and director of sports nutrition at Texas Children's Hospital.
Even though the portions of fruits and vegetables we eat are likely not big enough to minimize the need to actually drink our fluids, they're still a good source of "time-released" fluid, said Anding, who also works as a sports dietitian for the Houston Texans football team.
When a person drinks a glass of water, it leaves the stomach and gets into the blood stream relatively quickly, she explained. But food takes some time to be digested, so it's a delayed fluid response.
