How do fruits and vegetables contribute to daily water intake?
Fruits and vegetables are significant contributors to daily water intake because they are composed largely of water, typically ranging from 85 to 95 percent by weight for fresh produce. While water is consumed directly as a beverage, it is also a major component of many foods, and incorporating these items into your diet helps maintain the body's necessary fluid balance.12
Because 70 percent or more of their weight is water, fruits and vegetables serve as an essential source of hydration alongside their roles in providing vitamins, minerals, and fiber. For example, common items like lettuce, tomatoes, and grapefruit contain very high percentages of water, which contributes to their refreshing character.32
Maintaining adequate hydration is critical for bodily functions, including temperature regulation, the transport of nutrients and waste, and the maintenance of blood pressure. Since there is no single recommendation for daily water intake—as requirements vary based on activity level, climate, and diet—consuming water-rich foods is a practical way to support your overall fluid needs throughout the day.1
