If you’re looking to level-up your smoothies, adding some greens is a great place to start.

Dark green leafy vegetables are one of the most nutrient-dense foods on the planet, as they are packed with lots of essential vitamins and minerals that support our health.

So which ones are the best to use in smoothies?

You can pretty much add whatever greens you want, but there are a few that stand out when it comes to taste and nutrition.

Why Add Greens to a Smoothie?

Before we explore the best greens for smoothies, let’s briefly touch on why adding them into your smoothies is a great idea:

  • Rich in Nutrients: Greens (particularly dark leafy greens) are packed with vitamins, minerals and antioxidants, so adding a handful to a smoothie can help boost its nutritional benefits.
  • Support Digestive Health: Adding a cup of greens (like kale) to your smoothies can help increase the fibre content of your smoothies, which can help aid digestion and promote a sense of fullness.
  • Balanced Flavour: Greens might seem intimidating at first due to their earthy or ‘green’ taste, but when they are paired with fruits and other ingredients, they can help create a more balanced flavour that isn’t overly sweet.
  • Vibrant Colour: This might be a bit controversial, but I think green smoothies can look super visually appealing – which can make you want to drink more of it.

Green Smoothie Tips

Vary the types of greens

Eating a variety of plants is beneficial for our health and smoothies are a brilliant way to boost the number of different plants you’re eating.

So if you’re always reaching for the same greens for your smoothies, make sure to mix things up regularly to diversify your plant intake.

Make your smoothies balanced

Creating a balanced smoothie, with the right balance of nutrients, will help you stay full and energised for hours.

Most smoothies simply contain a blend of fruits and greens, but this can leave you feeling hungry again in as little as 30 minutes.

A balanced smoothie includes a mix of all 3 macronutrients (carbohydrates, proteins and fats) which can help you feel satisfied for longer and increase the variety of nutrients you are getting in a snack or a meal.

Freeze leftover greens

If you buy a bag of greens but don’t need the whole thing, put the rest into a freezer bag and use it in smoothies.

Not only does this help reduce your food waste, but it helps make smoothies cold without the need for ice!

Use a good blender

To avoid any lumpy bits of kale or spinach in your smoothies, it’s important to invest in a powerful, good quality blender.

Spring greens (known as collard greens in the US) are a member of the cruciferous vegetable family.

They aren’t as popular here in the UK, but they are widely available in most supermarkets during the spring months and can be an affordable source of various nutrients.

To help mask the slightly earthy flavour, I recommend blending a cup of Spring Greens with sweet fruits, like pineapple, mango and very ripe bananas.
