Why Water Remains the Unbeatable Champion
For pure, unadulterated hydration, nothing comes close to plain water. It is calorie-free, sugar-free, and contains no additives. Your body is composed of 60% water, and it is essential for nearly every bodily function, including nutrient absorption, detoxification, temperature regulation, and joint lubrication. The Centers for Disease Control and Prevention (CDC) and other health organizations consistently recommend water as the primary beverage for daily fluid intake. For those who find plain water uninteresting, options like sparkling water or fruit-infused water can provide flavor without compromising health benefits. Simply add slices of lemon, cucumber, or berries for a refreshing twist.
The Power of Tea: A Runner-Up with Benefits
After water, unsweetened tea—especially green and certain herbal varieties—is one of the healthiest beverages you can choose. Green tea is celebrated for its high concentration of antioxidants, particularly epigallocatechin gallate (EGCG), which can help fight cell damage and support heart health. Research has also suggested that green tea may offer benefits for metabolism and brain function. Beyond green tea, many herbal teas offer specific health perks. Peppermint tea, for instance, can aid digestion, while ginger tea has anti-inflammatory properties. The key is to avoid adding sweeteners, which counteract the tea's health benefits. For those who are sensitive to caffeine, herbal teas are an excellent, caffeine-free alternative.
Milk and Dairy Alternatives: Nutritional Powerhouses
For a boost of calcium, protein, and vitamins, milk is a highly nutritious beverage. Low-fat or fat-free cow's milk provides essential nutrients like calcium, potassium, and vitamin D, crucial for bone health. For those who are lactose intolerant or follow a plant-based diet, fortified plant-based milks such as soy or almond are excellent choices. When selecting a plant-based milk, it is important to check the label and choose unsweetened, fortified varieties to avoid unnecessary sugar and ensure you are getting key nutrients. Soy milk, in particular, offers a good source of protein, making it a well-rounded option.
Fermented Drinks and Juices: Proceed with Caution
Functional drinks like kombucha and kefir have gained popularity for their probiotic content, which supports gut health. However, their nutritional profile can vary significantly between brands. Many kombuchas contain considerable amounts of added sugar, turning a potentially healthy drink into a sugar-laden one. It is crucial to read the label and choose options with low sugar content. Similarly, while 100% fruit juice contains vitamins and antioxidants, the sugar is highly concentrated and fiber is largely absent, which can lead to blood sugar spikes. The Heart Foundation suggests limiting juice intake to a small glass (125ml) per day and opting for the whole fruit instead.

| Added Sugar | 0 | 0 | 0 | Varies (look for <5g/serving) |
| Key Nutrients | Hydration | Antioxidants, L-theanine | Calcium, Vitamin D, Protein | Probiotics, B-Vitamins |
| Primary Benefit | Core hydration, detoxification | Antioxidant protection | Bone health, muscle repair | Gut microbiome support |
| Who it's for | Everyone, all the time | Those seeking antioxidants | All except lactose intolerant/dairy-free | Those focused on gut health |
How to Make Smart Choices
Navigating the vast array of options can be overwhelming. The best strategy is to focus on a few key principles:
- Prioritize Water: Make plain water your default drink. Keep a reusable water bottle with you to ensure you stay hydrated throughout the day.
- Limit Sugary Beverages: Avoid or minimize your intake of sugar-sweetened drinks like sodas, energy drinks, and sweetened iced teas. These contribute to caloric intake without nutritional benefit and are linked to poor health outcomes.
- Read the Label: For any packaged drink, check the nutrition facts. Look for low-sugar, low-sodium options. Be especially wary of added sugars, which can hide in seemingly healthy products like fruit juice blends and flavored sparkling waters.
- Consider Customization: Take control of your beverages by making your own. Brewing your own tea, infusing water with fruits and herbs, or blending a low-sugar smoothie puts you in charge of the ingredients.

Conclusion: A Multi-faceted Answer
While plain water is objectively the healthiest drink on the market for universal hydration, the best choice depends on context. Green and herbal teas are excellent for adding antioxidant and other health benefits without calories. Fortified milks and their plant-based alternatives provide essential minerals and protein. Functional drinks like low-sugar kombucha can support gut health. The key takeaway is to build your beverage habits around plain water, using other nutritious, unsweetened options as supplemental choices to enhance your overall wellness.
