Understanding Food Water Content
While drinking water is the most direct way to stay hydrated, consuming water-rich foods plays a significant, complementary role. Our bodies are roughly 60% water, and maintaining this balance is critical for everything from regulating body temperature and lubricating joints to transporting nutrients and flushing waste. Foods with high water content are beneficial because they not only provide moisture but also deliver essential vitamins, minerals, and fiber. The 70% water range includes many everyday staples that are easy to incorporate into meals and snacks. Recognizing these hydrating options can help you make more informed dietary choices to support your overall health and well-being.
Fruits in the 70% Water Range
Many fruits are incredibly high in water, but several fall specifically within the 70-80% category, balancing hydration with other important nutrients. Unlike melons and berries, which can exceed 90% water, these fruits offer a more robust texture and nutrient profile while still contributing significantly to your daily fluid intake.
- Bananas: With a water content of approximately 76-80%, bananas are a great source of potassium, an essential electrolyte for regulating fluid balance. They are also known for providing sustained energy and fiber.
- Avocados: At around 73% water, avocados are unique for their high content of healthy monounsaturated fats. They also provide fiber, potassium, and vitamins K, E, and C.
- Cooked Yellow Corn: A cup of cooked corn contains approximately 70-80% water and provides fiber, vitamins, and minerals. It makes a delicious and hydrating side dish for many meals.
- Pears: Coming in at 80-84% water, pears are slightly higher but fit well into this discussion as a hydrating, fibrous fruit. They also offer antioxidants and support digestive health.
Protein and Dairy Sources with 70% Water Content
While many think of fruits and vegetables for hydration, several protein and dairy products also contain a substantial amount of water. These foods are excellent for building balanced, hydrating meals that keep you feeling full and nourished.
- Cooked Shrimp: Cooked shrimp contains approximately 70-80% water and is a lean source of protein. It also provides omega-3 fatty acids, iodine, and selenium, which support thyroid and immune health.
- Part-Skim Ricotta Cheese: This versatile cheese is in the 70-80% water range and offers a good dose of calcium and protein. It can be a great addition to both sweet and savory dishes, from lasagna to a fruit parfait.
- Plain Yogurt: Depending on the type, plain yogurt can range from 75-88% water. It is packed with protein, calcium, and probiotics that support gut health, making it more effective at rehydration than water alone in some contexts.
- Cottage Cheese: Similar to yogurt, cottage cheese is a protein-rich food that is also rich in water, with a content of around 80%. It provides calcium, phosphorus, and selenium and is great for muscle maintenance.

Benefits of Eating Hydrating Foods
Incorporating hydrating foods like those with 70% water content offers multiple benefits beyond simply quenching thirst. These advantages contribute to overall health and vitality in several ways:
- Weight Management: Foods with high water content, like many fruits and vegetables, have a low-calorie density. This means a larger portion contains fewer calories, helping you feel fuller for longer and potentially aiding in weight loss by reducing overall calorie intake.
- Enhanced Nutrient Delivery: Water is the medium for transporting nutrients throughout the body. By consuming hydrating foods, you ensure your cells receive the necessary vitamins and minerals more efficiently.
- Improved Digestion and Gut Health: The fiber found in many water-rich foods aids in digestion and prevents constipation. Additionally, dairy products like yogurt provide probiotics, which further support a healthy gut microbiome.
- Better Skin Health: Proper hydration is vital for maintaining skin elasticity and suppleness. The vitamins and antioxidants found in hydrating foods help protect skin cells from damage and promote a healthy glow.
- Sustained Energy Levels: Dehydration is a common cause of fatigue. By consuming hydrating foods throughout the day, you can help maintain consistent energy levels and avoid the slump that comes with inadequate fluid intake.
How to Incorporate 70% Water Foods into Your Diet
Making hydrating foods a regular part of your diet is simple. Consider these practical tips for integrating foods that are 70% water or more into your daily routine:
- Hydrating Snacks: Snack on bananas or avocado slices with a sprinkle of sea salt. The electrolytes in the salt help your body absorb and retain the water more effectively.
- Smoothies: Blend bananas and plain yogurt with a handful of strawberries or a squeeze of orange juice for a refreshing, nutrient-packed drink.
- Salad Toppings: Add cooked shrimp or cottage cheese to your salads to increase protein and hydration. Use a light, yogurt-based dressing for an extra boost.
- Cooking: Use cooked shrimp or salmon in pasta dishes or rice bowls. Corn can be added to salsas, soups, and stews to add texture and hydration.
- Creative Breakfasts: Top your morning oatmeal with sliced banana and a dollop of cottage cheese or yogurt. Or, create a savory scrambled egg bowl with a side of avocado.
Conclusion
While foods containing 70% water may not be as splashy as their 90%+ counterparts like cucumber and watermelon, they are a powerful and essential part of a well-hydrated diet. From the potassium-rich banana to the protein-heavy shrimp and yogurt, these foods offer a balance of fluid, nutrients, and fiber that supports overall health, digestion, and energy levels. By consciously integrating these items into your daily meals and snacks, you can easily and deliciously contribute to your body's hydration goals and enjoy the numerous wellness benefits that come with it. Hydration is not just about drinking; it’s about nourishing your body with water-rich foods, too.

Frequently Asked Questions (FAQs)
What are some common examples of foods that are 70% water?
Bananas, avocados, cooked yellow corn, cooked shrimp, part-skim ricotta cheese, and plain yogurt are common foods with a water content of approximately 70-80%.
How do foods with 70% water compare to foods with higher water content?
Foods with higher water content, such as cucumber (96%) and lettuce (95%), are excellent for hydration but often have lower caloric density and fewer macronutrients. Foods in the 70% range offer a better balance of water, protein, fats, and fiber, making them more substantial additions to a meal.
Can I get enough water from food alone?
While food contributes to your daily fluid intake, it is not sufficient for meeting all your hydration needs. Approximately 20% of your water intake comes from food, with the remaining 80% needing to come from beverages like water and other liquids.
Are there any surprising foods with high water content?
Yes, some foods are surprisingly water-rich. For example, cottage cheese is about 80% water and is a significant protein source. Even cooked salmon is approximately 65% water, which is more than many people might guess.
Do cooked foods lose their water content?
Some cooking methods, like boiling, can cause foods to absorb water, increasing their content (e.g., pasta), while others, like baking or roasting, can reduce it through evaporation. The water content of cooked foods can vary, but many, like cooked shrimp and corn, remain high in moisture.
What are the health benefits of eating hydrating foods?
Eating hydrating foods offers numerous benefits, including supporting weight management, improving skin health, providing essential nutrients and electrolytes, and promoting better digestion due to their fiber and fluid content.
Does the water in food provide electrolytes?
Yes, many water-rich foods, particularly fruits and vegetables like bananas and avocados, contain naturally occurring electrolytes such as potassium, which are crucial for fluid balance in the body.
