Is Water Or Milk Better In Smoothies?

Smoothies are an easy way to increase your daily fruit and vegetable intake. Blending raw fruits/veggies into drinkable form allows for easier digestion and absorption compared to eating whole produce. The dilemma is whether to use water or milk as the foundation for smoothie recipes.

Water and milk each have their advantages and disadvantages when making smoothies. Factors like nutrition, calories, taste, texture, convenience, and dietary restrictions need to be considered when deciding between the two bases. Read on to learn which liquid works best for different goals and lifestyles.

Benefits of Using Water as a Base for Smoothies

Using water as the liquid base for smoothies has several benefits:

Convenience and Accessibility

One of the best aspects of water is that it is readily available and easy to use. You don’t have to make a special trip to the store to buy milk to have on hand for smoothies. Every home has easy access to tap water or bottled water. This makes spontaneous smoothie-making simple.

Doesn’t Change Flavor

Since water has no inherent flavor, it won’t alter the tastes of the fruits and veggies you blend it with. This allows the natural flavors of the smoothie ingredients to shine. Other liquids like milk and juice can overpower the flavors.

Ideal for People Avoiding Dairy

Using water instead of milk allows people with milk allergies or lactose intolerance to still enjoy smoothies. Water-based smoothies are also good for those avoiding dairy for dietary reasons like vegan or paleo diets.

Low in Calories for Weight Loss

Water contains zero calories, so water-based smoothies will have a lower calorie count compared to using juice or milk. This can benefit people trying to lose weight through calorie control. The fewer liquid calories, the lower the total smoothie calories.

Hydrates the Body

Drinking smoothies made with water can help hydrate the body, which is essential for many vital functions. Staying hydrated aids digestion, regulates body temperature, boosts immunity, improves cognition, keeps energy levels up, and helps the kidneys flush toxins.


Using tap or filtered water as the base ingredient saves money compared to purchasing milk or expensive juices and nut milks. Water is free from the tap or extremely cheap when bought bottled or filtered. Smoothies made with water are very budget-friendly.

Doesn’t Affect Nutrient Absorption

Some compounds in milk and juice can inhibit the body’s ability to absorb certain nutrients from the whole fruits and vegetables blended into the smoothie. Water does not interfere with nutrient absorption.

Disadvantages of Using Water for Smoothies

While using water for smoothies has some clear advantages, there are a few potential downsides to consider:

Lacks Nutrients

Unlike milk, water does not provide any significant vitamins, minerals, protein, healthy fats, or carbohydrates on its own. While it won’t interfere with nutrient absorption from the produce, water does not add any nutritional value either.

Can Result in Thin Consistency

Watery smoothies with a thin, unsatisfying consistency are a common complaint when using water as the base. Without the natural thickness that milk and some juices provide, water-based smoothies can be quite runny if not prepared properly.

Blander Taste

Milk and some juices impart a richness and sweetness that enhances the taste of smoothies. Water does not affect the flavor profile at all. So water-based smoothies may taste more diluted or bland compared to using other liquids.

There are also several advantages that using milk can offer for smoothie recipes:

Highly Nutritious

Unlike water, milk contains many beneficial nutrients including protein, calcium, potassium, phosphorus, vitamins A, D, B12, riboflavin, and more. These compounds complement the nutrients from the fruits and veggies.

Good For Meal Replacement Smoothies

The protein, carbs, and nutrients in milk make it ideal for meal replacement smoothies that are designed to substitute for a full breakfast or lunch. Milk provides more staying power.

Provides a Creamy, Thick Texture

Milk naturally improves the texture of smoothies, making them rich, cold, and satisfying. The smooth, creamy consistency milk offers is what most people desire from a great smoothie.

Disadvantages of Milk as a Smoothie Base

However, there are a few drawbacks associated with using milk for smoothies instead of water:

Not Suitable for Vegans or Dairy-Free Diets

Milk is an animal product making it unsuitable for vegans. It also contains lactose so it must be avoided by those with lactose intolerance or dairy allergies. Alternative milks can be used instead.

Higher in Calories and Fat

The calories and fat naturally present in animal milk can tally up quickly when used as the base for smoothies, especially in larger portions. This may not be ideal for people restricting calories for weight loss.

Can Overpower Fruity Flavors

The thicker texture and creamy taste of milk can mute more delicate fruit flavors in a smoothie recipe. Berries, citrus fruits, tropical fruits, and stone fruits tend to taste less pronounced with milk as the base liquid compared to water.

Can Curdle with Acidic Ingredients

Milk is sensitive to acidic ingredients like citrus, pineapple, kiwi which can cause it to curdle or separate. This gives the smoothie a curdled, unpleasant texture and flavor.

Liquid Base Options for Smoothies

Water and dairy milk are not the only options to use as a base when making smoothies. There are several other choices including:

  • Dairy – cow’s milk, goat’s milk, kefir, yogurt, buttermilk
  • Plant-based milks – soy, almond, coconut, oat, hemp, rice, pea
  • Nut milks – almond, coconut, cashew
  • Fruit juices – apple, orange, pineapple, grapefruit
  • Coconut water
  • Coconut milk or cream
  • Kombucha
  • Iced tea
  • Iced coffee

Consider your goals, preferences, and dietary needs when selecting a smoothie base. Combining water and milk is another great option.

How to Make Thick Smoothies Without Milk

How to Make Thick Smoothies Without Milk

One common complaint about water-based smoothies is that they can turn out thin and watery. But there are easy ways to create richer, creamier smoothies using water instead of milk:

Use Plant-Based Milk Alternatives

Nondairy milks like almond, soy, coconut, oat, hemp all provide thickness that mimics dairy milk. They can be substituted 1:1 for cow’s milk in any smoothie recipe.

Blend in Frozen Fruit

Using frozen fruit is an easy way to guarantee a thick smoothie texture. The ice crystals that form when freezing rupture the fruit’s cell structure, allowing it to blend into a frosty, creamy consistency. Great frozen fruits for smoothies include bananas, mangos, pineapples, berries, and stone fruits.

Add Textured Fruits and Vegetables

Some fresh produce naturally provides more body and thickness when blended compared to watery fruits like citrus. Good options include avocados, applesauce, mangos, papayas, apricots, and cooked sweet potatoes or butternut squash.

Dollop in Nut Butters

Nut butters like almond, peanut, cashew and coconut butter add protein, healthy fats and silky thickness to smoothies. Add 2-4 tablespoons per smoothie.

Use Ground Seeds and Grains

Chia seeds, flax seeds, hemp seeds, oats and other grains can help create a thicker, more satisfying texture when blended with water. Soak chia and flax seeds for 5-10 minutes before blending to allow them to plump up.

Fill Up with Crushed Ice

If you don’t have frozen fruits, simply adding a cup or two of crushed ice and blending it completely mimics a frosted texture.

How to Make Smoothies Using Water as the Base

Using water for smoothies does take a bit more finesse compared to the natural thickness milk provides. Here are some tips:

Consistency Can Be a Challenge

Water simply does not provide any thickness or texture. All the texture for water-based smoothies must come from the fruits, veggies, nut butters, powders, and other mix-ins you add.

Water to Ingredient Ratios

  • Fruit and veggie-only smoothies = 1 cup water : 1.5-2 cups chopped produce
  • Smoothies with powders or nut butters = 1 cup water : 1 cup produce + 2-4 tbsp powder/nut butter
  • Smoothies with seeds, grains or greens = 1 cup water : 1 cup produce + 1-2 tbsp seeds/grains/greens

These ratios provide enough water for the blender blade to turn smoothly while maintaining an ideal texture. Add more water for thinner smoothies.

Blending Tips for Water-Based Smoothies

  1. Always add liquids to the blender first
  2. Chop produce into small, evenly-sized pieces for smooth blending
  3. Start blending at low speed to pull ingredients towards the blade, then increase to high speed
  4. Blend for 45-60 seconds at high speed or until completely smooth
  5. Add more water if needed for desired consistency
  6. Pour into a glass and enjoy immediately for best texture

Follow these tips and the ratio guidelines, and you can easily make delicious thick and frosty smoothies using water instead of milk.

Deciding whether to use water or milk as the base when making smoothies depends on your dietary preferences and needs. Water provides the benefits of being widely accessible, low calorie, neutral in flavor, and hydrating. But it lacks the natural creaminess of milk. For thicker, richer smoothies, plant-based milks can be substituted for dairy, or texture can be added with frozen fruit, nut butters, oils, and ground seeds or grains. With the right ratios and a blender, smoothies with water can be just as satisfying. Consider your individual health goals and lifestyle when choosing between the two options.
