If you know me one bit, you’ll know I’m a HUGE fan of smoothies - they’re part of my breakfast 5 days out of 7, and I’ll often have a juice or a smoothie mid-afternoon as well as a pick-me-up if I’ve had a very go go go day! I recommend them to many of my nutritional clients as well, for the reasons I’ll delve into now...

Sugar and carbohydrates from whole foods aren’t “bad” - it’s a case of everything in moderation.

With smoothies and juices however, it’s so easy to overdose on sugar if you’re unaware of the hidden sources. The sugar content regardless of whether it’s from fruit or not can easily climb up to 50 g of sugar in some smoothies.

If you’re an active person and you exercise, walk to work etc. then that’s not an issue. However most people drink a (sugar-filled) juice or smoothie thinking they’re choosing a “healthy option” and then spend a lot of time sat down, which after weeks or months of enjoying that habit, is likely going to play havoc with their health and body composition.

The goal is to combine fruits with protein, fiber, vegetables (especially greens) and healthy fats so you have a balanced meal.

Here are some simple tips and tricks to down-level the sugar content of your smoothies effortlessly, whilst still keeping them tasting great.

Adding zucchini into smoothies is the most genius and creative way to get more veggies into your diet.

It adds fiber, potassium, manganese, vitamin C and vitamin A as well as a creamy texture to your smoothies. They also have a very neutral taste so if you’re worried about them overpowering the flavor, panic not.

They are really easy to prep; chop them into chunks and put them in a freezer bag. Then you can just throw a couple of frozen zucchini pieces into your blender, along with your other ingredients.

This shaves off valuable time in the morning and means you don’t need a constant stock of fresh zucchini in your refrigerator - win-win.

This is my favorite fruit to add to smoothies, for its healthy fats, fiber and creaminess. They also contain vitamin E and K, potassium and folate. Like I suggested with the zucchini, you can keep a stash of frozen avocados in your freezer.

Simply cut the avocado in two using a sharp knife, remove the stone and then scoop out the flesh from the skin using a large spoon.

Chop the flesh into 2-3 chunks for each half and store the avocado in a freezer bag. That way you don’t have to wait for the narrow window of time to use a perfect avocado!

If you’re currently using a fruit juice as the base to your smoothie, switch this to filtered water, unsweetened almond or coconut milk or if you haven’t already tried it, unsweetened green tea!

Green tea pairs really well with smoothies and you’ll also benefit from the antioxidants and bioflavonoids that are present in the tea.

Brew a cup of tea and leave it in your fridge overnight so you can add it to your smoothie in the morning.

This is my husband’s favorite ingredient in his smoothie. Whenever he makes them for me I know they’re in there somewhere!

Again, they’re flavorless but they’re an ingredient that is often in peoples freezers and they’ll add protein, vitamins K, B1 and C, fiber and essential minerals.

vegetables 5


The addition of cucumbers is an amazing way to increase the water content of your smoothies since they’re such a high-liquid vegetable.

They also contain a good amount of fiber, polyphenols, vitamin C and antioxidants.

Top tip: choose organic when possible.

Beets are naturally sweet and they lend such an incredible ruby-red color to the smoothie.

They’re also high in vitamin C and essential minerals.

Top tip: chop up your raw beets into bite-sized chunks and freeze them.

If you want to steam them for 15 minutes before freezing them then you can do, but I often just chop them up and put them straight in the freezer in my smoothie-devoted drawer.
