17 Vegetables Highest in Water

Water is an essential nutrient required to maintain homeostasis in our bodies. (1)

A deficiency in water, called dehydration, leads to headaches, loss of appetite, confusion, unexplained tiredness, and even seizures. (2) Excessive dehydration can even lead to death.

Conversely consuming too much water can lead to disorientation, confusion, nausea, vomiting, and in extreme cases, death. (3)

The U.S. Reference Dietary Intake (RDI) for water is 3.7 liters (130oz) per day for men and 2.7 liters (95oz) for women. (4) Though people who are active and under the sun should consume more.

Of all foods, vegetables provide the most water, often being over 90% water by weight. Vegetables high in water include lettuce, celery, bok choy, radish, cucumber, zucchini, watercress, tomatoes, green bell peppers, and asparagus.
