How long will this green smoothie last in the fridge?

You can store this green smoothie for 24 hours in the fridge, but it can keep up to 48 hours.

When storing smoothies, like for other cut or processed fruits and vegetables, it's essential to keep them refrigerated in tight seal containers. Heat and air are key factors responsible for food browning, spoiling, and loss of nutrients.

The oxygen in the air reacts with the plant chemicals, known as phenolic compounds, which have become exposed after cutting the fruit or vegetable. This process, called oxidation, causes the fruit to become brown and to lose essential nutrients, including vitamin C, vitamin A and E [1].

Therefore, storing this smoothie in an airtight bottle filled almost to the top will slow down the oxidation process. Also, by keeping it in the fridge, the low temperature will delay the depletion of vitamins.

As an extra tip to keep the smoothies for longer, you can try to use fruit and vegetables high in antioxidants, like berries and kale, or to add a splash lemon juice.

How to make a blueberry smoothie without milk or yoghurt?

Making a blueberry smoothie without milk or yoghurt is incredibly simple, as you can replace them with plant-based alternatives. For example:

  • Almond milk

  • Oat milk

  • Coconut milk

  • Soy yoghurt

  • Coconut yoghurt

Also, as milk and yoghurt are used to add thickness and creaminess to the smoothie, you can swap them with the following ingredients:

  • Bananas

  • Soaked flaxseeds

  • Soaked chia seeds

  • Avocado

  • Nut butter, like peanut butter or almond butter

Can green smoothies replace vegetables?

A balanced smoothie can certainly help you reach the recommended intake of 5 servings of fruit and vegetables, promoting a healthier lifestyle. It might also be useful for those on a detox diet or with digestive problems.

However, smoothies shouldn't replace all the other sources of fruit and vegetables in your daily diet. National guidelines and health professionals recommend that these drinks should account for 1 to 2 servings of fruit and vegetables a day.

The reason being, processed fruits and vegetables are more easily digested than their whole counterparts. Therefore, your digestive system wouldn't have to work much to get to those nutrients, making you feel empty and hungry soon after.

Also, upon blending, the sugar molecules are released from the cells of fruits and vegetables, and they become free sugars. These sugars raise blood glucose levels more quickly than when they are found in the whole fruit[4]. They will make your blood sugars spike, eventually leading to a crush of energy, and even overeating and weight gain.

Moreover, just drinking smoothies won't make up for a balanced and healthy diet. You still have to consume meals rich in whole grains, healthy fats, and lean proteins.

To sum up, if smoothies help you include more fruit and vegetables in your daily diet, then by any mean keep enjoying them. You'll get vitamins, minerals, and antioxidants. However, try to limit them to 1 to 2 servings a day, and balance your diet with other sources of fruit and vegetables.


Measuring System
Watercress60 g
Fresh Basil Leaves1 tsp
Ginger Root4 g
Coconut Water250 mL
Matcha Powder (optional)1/2 tsp
Blueberries160 g

Step 1

Rinse and drain the watercress, and then remove the stems to have a creamier smoothie that is also easier to digest.

In a food processor, add the watercress, fresh basil leaves, 1 banana, ginger root, 125 mL of coconut water.

For a boost of energy and antioxidants, add the matcha powder. It will make this green smoothie even greener!

Step 2

Blitz the ingredients until you have a creamy green smoothie.

If you enjoy drinking from a straw, know that the bananas make this drink quite dense. We found you can still use a straw though. However, if you prefer a runnier smoothie, add a splash of coconut water and pulse again.

Step 3

Set the green smoothie aside, and add in the food processor blueberries, dates, 1 banana, and the remaining 125 mL of coconut water.

If the dates are a bit chewy, you can pre-soak them and 10 minutes and then add them to the food processor bowl. This way, they will blend more easily into a paste.

Blitz the ingredients until they turn into a creamy smoothie.

Step 4

Now, you are ready to pour this delicious smoothie into serving glasses.

For a beautiful presentation, pour the green smoothie first filling the glass halfway. Then, pour the blueberry smoothie to fill the glass. You can top it with blueberries, a leaf of watercress, and bee pollen.

In an alternative, you can mix the watercress smoothie with the blueberry smoothie in the glass for a swirl of colours.
