Short answer: Yes, food counts. The CDC notes that daily water intake comes mostly from water and other drinks, but foods, especially many fruits and vegetables with high water content, add to it. In the U.S. survey behind the National Academies' reference values, water in food made up roughly a fifth of total water intake. Food supplements your drinks; it doesn't replace them.
When people picture "drinking enough", they picture the glass. The glass matters most, but it isn't the whole story. Here's how the plate fits in.
Does food really count toward your daily water?
Yes. Official reference values already include it. The National Academies' adequate intakes, about 2.7 litres a day for women and 3.7 litres for men aged 19 to 30, are for total water from all drinks and all food.
In the survey those values were built on, drinking water and other beverages provided about 81 percent of total water intake. Food supplied most of the remaining fifth.
Which foods add the most water?
Foods that are naturally juicy or cooked in water add the most. The CDC singles out fruits and vegetables with high water content. Everyday examples:
- Vegetables: cucumber, lettuce, celery, zucchini, tomatoes, peppers
- Fruit: watermelon, strawberries, oranges, grapes, cantaloupe
- Prepared foods: soups and stews, oatmeal, cooked rice and pasta, yogurt, milk on cereal
You don't need to memorise percentages. A meal with vegetables, fruit or a soup brings water with it, and a meal of dry, salty snacks brings much less.
If food counts, can you skip drinking?
No. Drinks still do most of the work. The CDC states that daily water intake is "mostly from water and other beverages", and in the reference survey beverages were about four-fifths of the total.
Food is a helpful contributor, not a substitute. That's especially true on hot days or active days, when needs go up (see How much water do you need a day?).
How can you use this at your next meal?
Pair the plate and the glass. Both the CDC and Canada's Food Guide suggest drinking water with meals.
- Set out a glass of water when you set the table, or fill your bottle before you sit down to lunch.
- Add one fruit or vegetable you actually enjoy to the meal. Enjoyment is what makes it repeatable.
- At work, pack something juicy like grapes, cucumber slices or an orange alongside lunch.
- In winter, lean on soups and stews. They're warm, and they add water. (See A daily hydration routine.)
Does food also supply electrolytes?
Yes, for most people it's the main source. Potassium and magnesium come mostly from vegetables, fruit, beans, dairy, nuts and whole grains. Sodium comes mostly from packaged and restaurant food.
That's one reason most adults don't need electrolyte drinks for everyday activity. (See Where most of your electrolytes already come from: food and Do you need electrolytes every day?.)
A note on limits
Needs vary with age, body size, activity and heat. Some people have prescribed fluid limits or medical conditions that change the picture. If that's you, follow your own care team's guidance; general articles like this one don't apply.
Common questions
Does food count as water intake? Yes. In the survey behind the reference values, water in food made up roughly a fifth of total water intake. Drinks provided the rest.
What foods have the most water? Many fruits and vegetables, such as cucumber, lettuce, watermelon, strawberries and oranges, plus soups, yogurt and grains cooked in water.
Can I eat my water instead of drinking it? Not entirely. The CDC says daily water intake comes mostly from water and other drinks. Food helps, but it doesn't replace them.
Is soup hydrating? Soup is mostly water, so it counts toward your fluids. Broth-based soups can be high in sodium, so check the label if you're watching salt.
