This is general information, not medical advice. Individual fluid needs vary, and anyone on a fluid-restricted plan, or with a heart, kidney or other health condition, should follow their own clinician’s guidance before changing what or how much they consume.
Food counts toward fluid intake
Water does not only arrive in a glass. Many foods contain a good deal of it, and people commonly get a meaningful portion of their daily fluid from what they eat. Exactly how much differs by person and diet, and people who eat plenty of produce usually take in more water through food than those who eat mostly dry, packaged items.
That makes food a handy way to support hydration, especially for people who do not enjoy drinking lots of plain water.
Water-rich fruits and vegetables
As a general rule, fresh produce that feels juicy or crisp tends to contain a lot of water. Common examples include:
- Watermelon, strawberries, cantaloupe and oranges
- Cucumber, lettuce, celery and zucchini
- Tomatoes and bell peppers
- Grapes, peaches and pears
These foods also provide fiber, vitamins and various dietary minerals. Frozen produce usually keeps much of its water too, and it can be a practical option when fresh items are out of season or expensive. Seasonal eating often makes juicy fruit more affordable and more flavorful in summer.
Soups, stews and other meals with liquid
Brothy soups, stews, oatmeal made with water or milk, yogurt and smoothies all contribute fluid. A bowl of soup in winter, for instance, is both comforting and a source of liquid. The caution here is sodium: canned and restaurant soups can be high in salt, so it helps to glance at the nutrition facts label and consider lower sodium versions if you are watching your salt intake. If a clinician has advised you on sodium, follow that advice.
Drinks that count
Many drinks besides water contribute to your fluid intake:
- Milk and unsweetened fortified plant drinks. These provide fluid along with other nutrients such as protein, depending on the product.
- Herbal tea and regular tea. A cup of tea is mostly water. Green tea is a popular choice, and it contains some caffeine, so keep your total in mind.
- Coffee. Caffeine has a mild diuretic effect in some people, but for people who drink coffee regularly, the fluid it provides generally still counts toward intake. Timing matters for sleep, so see caffeine and sleep if late-day coffee affects you.
- Sparkling or flavored water. Unsweetened versions are a good alternative to soda for those who like fizz.
- Diluted juice. A splash of juice in sparkling water gives flavor with less sugar than a full glass.
Drinks to treat with a little more care
Sodas, sweetened teas, energy drinks and many bottled coffee drinks contain fluid, but they can carry a lot of added sugar, and some contain high amounts of caffeine. Most people find these work better as occasional drinks than as the main source of fluid. Energy drinks in particular are not suited to children, and anyone sensitive to caffeine or with heart concerns should be especially careful.
Alcohol is a different case. It tends to increase urination, so it is generally not a helpful source of hydration, and drinking it alongside exercise or hot weather can add to fluid loss. If you drink alcohol, doing so in moderation and alternating with water is a common sensible approach, and a professional can advise on what is right for you.
Sports drinks and electrolyte products
Sports drinks and electrolyte mixes contain sugar and salts. For most people doing ordinary activity, plain water and normal meals are enough. They may be useful in some circumstances, such as long periods of heavy sweating, which is covered under hydration during exercise. Products marketed as hydration boosters vary a great deal, so read labels, and ask a professional if you have blood pressure, kidney or heart concerns.
Putting it into your day
A few easy ideas:
- Add fruit or a side salad to lunch.
- Have yogurt with berries as one of your quick breakfasts.
- Choose cut cucumber, grapes or orange slices when you want healthy snacks.
- Keep soup in the freezer from meal prep so a fluid-rich meal is always handy.
- Build a balanced plate with at least some vegetables or fruit at most meals.
What food cannot do
Food and other drinks help, but they do not replace paying attention to your body. If you are active, sweating a lot or sick with vomiting or diarrhea, you may need extra fluids beyond what meals supply. If symptoms of dehydration develop or persist, seek medical advice rather than relying on watermelon.
