The Undisputed Champion: Water
For most people, plain water is unequivocally the healthiest drink to have every day. Its benefits are numerous and far-reaching, directly supporting nearly every bodily function without adding unnecessary calories, sugar, or additives. Water keeps you hydrated, which is crucial for preventing fatigue, mood changes, and kidney stones. It helps maintain a normal body temperature, lubricates joints, and protects sensitive tissues. For those watching their weight, replacing sugary drinks with water is an easy way to reduce caloric intake.
Making Water More Enjoyable
Some people find plain water boring, which can make it challenging to meet daily intake goals. Fortunately, there are many simple ways to add natural flavor without sacrificing health benefits:
- Infused Water: Add slices of fresh fruit like lemon, lime, berries, or cucumber to a pitcher of water for a refreshing boost.
- Herbal Additions: A sprig of mint, some crushed ginger, or basil can give water a uniquely clean and invigorating taste.
- Sparkling Water: For those who miss the fizz of soda, unsweetened sparkling water with a squeeze of citrus is an excellent, low-calorie alternative.
Other Top Contenders
While water is the ideal foundation, several other beverages offer unique, daily-appropriate health benefits when consumed in moderation and without added sugar.
Green Tea
Packed with antioxidants called catechins, particularly EGCG, green tea is a potent tool for promoting good health. Daily consumption has been linked to a reduced risk of various chronic diseases, improved cognitive function, and enhanced fat burning. Studies suggest that 3-5 cups per day may offer optimal benefits. It’s important to brew it at home to avoid the high sugar content found in many bottled versions.
Kefir
This fermented milk drink is a powerhouse of probiotics, which are beneficial bacteria essential for maintaining a healthy gut microbiome. A balanced gut can influence everything from immunity to mood. Plain, unsweetened kefir is the best choice, and starting with a small amount (like 4-8 ounces) is recommended. For those with lactose sensitivities, kefir can often be easier to digest than regular milk.
Unsweetened Coffee
Black coffee is rich in antioxidants and has been associated with a lower risk of type 2 diabetes, liver disease, and heart disease. Moderate consumption (around 3-4 cups a day) is generally considered healthy, provided it is consumed black or with minimal, healthy additions. Using a paper filter may also help remove certain compounds linked to increased cholesterol.
Milk (Dairy and Fortified Plant-Based)
Milk provides an excellent source of nutrients like calcium, protein, and vitamin D, which are vital for bone health and muscle repair. Studies have even shown that milk can be more hydrating than plain water due to its nutrient composition. Opt for low-fat or fat-free dairy milk, or choose unsweetened, fortified plant-based alternatives like soy or almond milk for a nutrient boost.
The Healthy Drink Comparison Table
| Drink | Primary Benefit | Daily Consumption | Best For... |
|---|---|---|---|
| Water | Essential hydration, zero calories | Varies by individual, generally 4-6 glasses | All-purpose, foundational hydration |
| Green Tea | High in antioxidants (EGCG), fat-burning | 3-5 cups, unsweetened | Antioxidant intake, brain function |
| Kefir | Probiotics for gut health | 4-8 ounces, plain | Digestive health, immunity |
| Black Coffee | Antioxidants, energy boost | 3-4 cups, unsweetened | Mental alertness, disease prevention |
| Low-Fat Milk | Protein, calcium, vitamins | 1-2 servings | Bone health, post-workout recovery |
Beverages to Limit or Avoid
For optimal health, some beverages should be limited or avoided entirely due to high levels of sugar, artificial sweeteners, or excessive calories. These include:
- Sugary drinks: Sodas, fruit drinks, and energy drinks are loaded with empty calories that contribute to weight gain and disease risk.
- Excessive fruit juice: While 100% juice has some nutrients, it lacks the fiber of whole fruit and contains high amounts of natural sugar. Limit to a small glass (150ml) per day.
- Diet soda: Although low in calories, research on the long-term health effects of artificial sweeteners is mixed, and they may still influence weight gain or metabolic health in some cases.
The Role of Alcohol and Moderate Consumption
Alcohol should also be consumed sparingly. For healthy adults, moderate intake is defined as one drink per day for women and two for men. Excessive alcohol consumption is linked to numerous health issues. There are many reasons why choosing water over alcohol or sugary mixers is a better choice for your overall health.
Conclusion: Making the Best Daily Choice
For the vast majority of people, the answer to what is the healthiest drink to have every day is simple: water. It provides fundamental, calorie-free hydration that is essential for life. However, other unsweetened and minimally processed beverages like green tea, coffee, and kefir can be part of a healthy daily routine, offering complementary benefits for brain function, gut health, and more. By prioritizing water and enjoying other healthful drinks in moderation, you can build a solid foundation for your overall wellness. Consulting with a doctor or registered dietitian can help you determine the right fluid intake for your specific needs, activity level, and health conditions.
