What drinks are allowed on the DASH diet?

4 min read

The DASH diet was named "Best Heart-Healthy Diet" and "Best Diet for High Blood Pressure" by U.S. News & World Report in 2025. A crucial component of this eating plan is knowing what drinks are allowed on the DASH diet to support cardiovascular health and manage hypertension.

Quick Summary

The DASH diet emphasizes heart-healthy hydration by encouraging water, unsweetened tea, coffee, and low-fat dairy. It strictly limits sugary beverages, excessive alcohol, and high-sodium drinks to support blood pressure management.

Key Points

  • Water is Best: Water should be your primary beverage for healthy hydration on the DASH diet.

  • Unsweetened is Key: Opt for unsweetened coffee and tea, avoiding added sugars and syrups.

  • Moderate Caffeine: The DASH diet has no specific rule on caffeine, but monitor your own reaction to it.

  • Choose Low-Fat Dairy: Stick to low-fat or fat-free milk and yogurt for your dairy servings.

  • Juice in Moderation: Limit 100% fruit juice to a small ½ cup serving and choose no-sodium vegetable juice.

  • Avoid Sugary Drinks: Steer clear of sodas, sweetened teas, and fruit punches that are high in added sugars.

  • Limit Alcohol: Follow recommended guidelines for alcohol consumption, as excessive intake can increase blood pressure.

  • Read Labels Carefully: Always check for hidden sugars and sodium in store-bought beverages.

Essential DASH-Friendly Drink Choices

Proper hydration is key to any healthy lifestyle, and the DASH (Dietary Approaches to Stop Hypertension) diet is no exception. The right beverage choices can support your efforts to lower blood pressure, while the wrong ones can undermine them. The core principle is to choose unsweetened and low-sodium options whenever possible.

Water

Water is the best choice for hydration on the DASH diet and should be your primary beverage.

  • Plain Water: Drinking at least eight glasses of water per day is an excellent goal for overall hydration.
  • Sparkling Water: Unsweetened, sodium-free sparkling waters (like seltzer, not club soda which may contain sodium) are a good way to add some variety.
  • Infused Water: Add slices of fresh fruit or herbs like lemon, cucumber, or mint to plain water for a refreshing and flavorful twist.

Tea and Coffee

For many, a daily cup of tea or coffee is non-negotiable. The good news is these are generally allowed on the DASH diet, with a few important caveats.

  • Unsweetened: Always opt for unsweetened versions of both tea and coffee. Avoid adding sugar, syrups, or full-fat cream.
  • Caffeine: The DASH diet doesn't specifically restrict caffeine, but its effect on blood pressure varies by individual. If you have high blood pressure, discuss your caffeine intake with your healthcare provider. Green tea, in particular, may offer additional blood pressure-lowering benefits.

Low-Fat Dairy and Dairy Alternatives

Low-fat and fat-free dairy products are an important part of the DASH diet, providing calcium and protein.

  • Low-Fat Milk: Low-fat or fat-free milk is a great source of calcium and other nutrients.
  • Plant-Based Milks: Unsweetened plant-based milks like almond, soy, or oat milk are suitable alternatives, but be sure to check labels for added sugars and sodium.

Vegetable and Fruit Juices

While whole fruits and vegetables are always preferred, you can still enjoy juices in moderation.

  • No-Sodium Vegetable Juice: If you choose vegetable juice, make sure it is specifically labeled "no sodium added" to avoid excess salt.
  • 100% Fruit Juice: Limit 100% fruit juice intake to a small serving, typically ½ cup, as even natural fruit juice contains concentrated sugar without the fiber of the whole fruit. Juices like beet, tomato, and pomegranate have shown promise in lowering blood pressure.

Drinks to Avoid or Limit on the DASH Diet

Just as important as knowing what to drink is understanding what to avoid. These beverages can counteract the blood pressure-lowering benefits of the DASH diet due to high sugar, sodium, or alcohol content.

  • Sugar-Sweetened Beverages: This includes soda, fruit punch, sweetened iced tea, and many lemonades, all of which are loaded with added sugars.
  • Energy Drinks: These beverages are typically high in both sugar and caffeine, and research suggests they can significantly increase blood pressure.
  • Alcohol: Excessive alcohol consumption can raise blood pressure. The DASH diet recommends limiting intake to two drinks per day for men and one for women.
  • Club Soda with Sodium: Unlike plain seltzer, some club sodas contain added sodium, so always check the label.
  • Sweetened Coffee/Tea: Drinks with added sweeteners, such as those found in many specialty coffee shop beverages, should be avoided.

Comparison of DASH-Friendly vs. Non-Friendly Drinks

Feature DASH-Friendly Drink Non-Friendly Drink Key Takeaway
Sugar Content Unsweetened, no added sugars High in added sugars or syrups Added sugars can negatively impact blood pressure.
Sodium Content Zero to very low sodium Often high, especially in vegetable juices and club soda High sodium is a key contributor to hypertension.
Caffeine Impact Moderate intake (green tea may offer benefits) Excessive intake, especially from energy drinks Varies, but excessive caffeine can temporarily spike blood pressure.
Dairy Type Low-fat or fat-free Full-fat dairy beverages Lower saturated fat intake is crucial for heart health.
Calorie Source Primarily water-based or nutrient-dense "Empty" calories from sugar and fat Focus on nutrient-rich hydration over empty calories.
Examples Water, unsweetened tea, skim milk, beet juice Soda, sweetened iced tea, energy drinks, cocktails Simple, whole-food-based drinks are always a safer bet.

Creating Hydration Habits on the DASH Diet

Incorporating healthy beverage habits into your daily routine is a key part of long-term success with the DASH diet. Here are some actionable tips to help you stay hydrated the right way:

  • Make Water Your Default: Always keep a reusable water bottle with you. Making water easily accessible throughout the day can significantly increase your intake.
  • Flavored Water Hacks: If you find plain water boring, create your own infused water with fresh fruit, herbs, or vegetables. Popular combinations include cucumber-mint, strawberry-basil, or lemon-ginger.
  • Smoothies: For a delicious and nutrient-packed option, try a smoothie made with low-fat yogurt or milk, fresh fruit, and a handful of spinach. This is an excellent way to get extra fruit and dairy servings.
  • Mindful Coffee and Tea: Enjoy unsweetened coffee or tea, and experiment with spices like cinnamon or nutmeg instead of sugar. Use low-fat milk for your lattes instead of higher-fat creams.
  • Limit Juice and Alcohol: Practice portion control with 100% fruit juice, limiting yourself to a single ½ cup serving per day. If you drink alcohol, stick to the recommended limits to avoid blood pressure spikes.
  • Read Labels: Always check the nutrition labels on store-bought drinks, especially flavored seltzers and plant-based milks, to ensure there are no hidden added sugars or sodium.

Conclusion

Making informed choices about your beverages is a simple yet powerful step towards successfully following the DASH diet and improving your heart health. By prioritizing water, unsweetened teas, coffee, and low-fat dairy while limiting sugary drinks and excessive alcohol, you can effectively manage your blood pressure and support your overall well-being. The key is consistency and being mindful of hidden sugars and sodium in prepared drinks. Incorporating these healthy beverage habits can lead to lasting benefits far beyond just managing hypertension.
