Common smoothie mistakes

Adding too much fat: Yes, it’s important to include healthy sources of fat in the diet and fat shouldn’t be feared. However, obtaining the necessary amount of fat is rather easy as they tend to be dense foods. Consequently, people often add too much fat-based ingredients, and the calories can start to spike. Generally, a tablespoon of seeds or nut butter will provide sufficient quantities of fat for a meal. Just remember to measure portions if you are rigorously tracking calories or watching your macros.

Adding too much fruit: The merits of including fruit in the diet are endless, from providing sources of antioxidants to fibre and nutrients; let’s not forget that fruit is a healthy natural sweet treat too. With that in mind, it’s important to be conscious that fruit can be high in sugar, particularly the likes of bananas and pineapples. Avoid a sugar spike by adding 1 portion of fruit. If you’re mixing fruits, opt for a cup of mixed fruits as your serving guide.

Tip: Use the freshest ingredients as possible, especially when it comes to fruit and vegetables. This will not only enhance the flavour, a greater nutrient content is also likely to be present in fresher foods.

Avoiding vegetables: Don’t be afraid to include some vegetables in your smoothie. It’s a fantastic way to increase your 5 a day, and the best part is you often won’t even detect the taste as it’s camouflaged by the other ingredients. Vegetables are often low in sugar and calories and provide important micronutrients. Kale and banana is a popular choice of smoothie that is fruit and vegetable based. Try adding a handful of spinach or kale to your next smoothie to test the theory!

Portion control: Some people will guzzle a smoothie as simply a drink alongside their breakfast or main meal. What they neglect to consider is that smoothies can contain a substantial amount of macronutrients and calories, so much so that a serving of a smoothie often constitutes a meal in itself. Take this into consideration when you are planning your meal and smoothie portions to ensure that you don’t overindulge or eat outside of your food plan.

Tip: Serving your blended smoothie in a bowl may give you the impression that it’s a meal as opposed to just a drink. This also allows you to consume it in a more mindful fashion.

Tip: Hold back some of the chopped fruit from being blended and instead use it to garnish the smoothie as a topping.

Did you know? Some store-bought smoothies contain as much as 15g sugar per 150ml; that’s equivalent to almost 4 teaspoons of sugar! Plus, if you drink the whole bottle (which is rather compact in size and considered 3 servings by the manufacturer), you’ll have swallowed a staggering 45g sugar, or almost 11 teaspoons of sugar! Remember, the World Health Organisation recommends a maximum of 5 – 10 teaspoons of free sugar per day, so you would be immediately over your sugar limit for the entire day.

Tip: Add grains to your smoothie if you want to bulk it up or make the smoothie a substantial meal, e.g. oats, a sprinkle of granola once it’s blended.

Tip: Fruit juice is often included in the ingredients to enhance the sweetness. Eliminate it entirely if you can and substitute it with the above flavourings. If you can’t bring yourself to eliminate fruit juice, at least minimise the amount of fruit juice that you add to the smoothie, as it does contain a substantial amount of sugar.

  • Avoid adding excess fruit to your smoothie as it can cause a sugar spike
  • Store-bought smoothies can contain high quantities of sugar, especially if their primary ingredient is fruit
  • Avoid adding fruit juice to smoothies to limit the sugar content
  • Aim to include at least 1 serving of vegetables in your smoothie, e.g. a handful of kale, 1 carrot
  • A single serving of fat is often sufficient as it is a dense food, e.g. 1 tablespoon chia seeds or 1 tablespoon of nut butter
  • Adding a handful of ice cubes is a healthy way to bulk up your smoothie and increase your water consumption

Hi Sharon,

I must say, this was a very timely article to chance upon! I’ve recently bought a plant protein powder and making my own breakfast smoothies. Was wondering how else I could make it more interesting.

What recipe would you suggest to incorporate veggies and plant protein powder? Open to suggestions!

Thanks for the article, I had a great read.


    Sharon · 26/07/2020 at 2:37 PM

    Hi there,

    Thank you so much, I’m glad you enjoyed the suggestions I provided in the post. I hope the article was of use to you and you found some options to try. If I’m honest, all the suggestions I provided in the blog, but as an example, you could mix protein powder with kale and banana, which is delicious. Try a few of the recipes and let me know how you’d get on.

    Best wishes,

I really want to get into to smoothies, they are a great way of getting your 5 a day but the sugar content always has concerned me, thats unbelievable that a whole small bottle will take you way over your daily allowance!
By making your own your totally in control of this which is great.
What is spirulina I’ve heard of it but no idea what it is?

    Sharon · 27/07/2020 at 8:39 PM

    Hi Amy,

    Good to hear, I’m glad you’re conscious of your sugar intake. Yes, it is exceptional to think that it is being marketed as healthy! That is, after all, one of my key goals with these posts. Spirulina is a type of algae that can come in powder format. It’s packed with nutrients, so it’s a great addition to smoothies, amongst a range of other foods. Certainly worth trying it out too!

    Thanks for the feedback.

    Best wishes,

This is an awesome article on how to make smoothies healthy, I always thought the main ingredients in smoothies were fruit. Now I know fruit actually is not the healthiest ingredient to use in a smoothie, you have provided so many healthy ingredients to choose from. So now your readers can benefit from smoothies without all the sugar, I thank you for sharing this incredible information


    Sharon · 27/07/2020 at 8:42 PM

    Hi Jeff,

    Good to hear, I’m glad you found it valuable and learned a few pieces of important information along the way! Yes, that’s true and I do hope my readers take this on board about limiting fruit in their smoothies.

    Thanks for the feedback.

    Best wishes,

Great article, Sharon! I love smoothies (some might call me the Smoothie Queen. Haha), but I definitely need to make more health-conscious decisions in my consumption of them (I’ve had way too many Naked smoothies during my lifetime). I’ve never liked pineapples (and though I like bananas, the taste of it in smoothies always seemed strange to me), but I definitely want to try more fresh blueberries, raspberries, strawberries, grapes, and mangoes in my smoothies. These fruits provide a plethora of vitamins and minerals, don’t have much sugar, and go down very easily. Oddly enough, I don’t usually include vegetables in my smoothies, but I definitely think it’s time to start-carrots, spinach, broccoli, corn and kale have my name on them. Haha. Yummy! Great read! God bless you!

    Sharon · 28/07/2020 at 6:21 PM

    Hi there,

    Wow you must know a thing or 2 about smoothies so! Vegetables are key to include, especially to keep the sugar levels lower. What’s great is that you often don’t even notice the vegetables present at all! I’m glad you enjoyed the suggestions I provided in the post.

    Best wishes,

Hi Sharon,

I really enjoyed your article on smoothies. It is a common misconception that a smoothie is healthy, regardless of where it’s obtained from or how it’s made. I actually have a BA in Nutrition Science and for 5 years, all I learned was food.
Because I know so much about food, when I try to help my family or friends out, they usually just get upset with me because most of what we put in our bodies is opposite of healthy. 99.9% of “Healthy Foods” marketed in the stores is actually really bad for us.
Breaking down the entire smoothie category like you did will help people that actually WANT to be healthy, understand what to put in there and what not to.

Overall, I really enjoyed reading this!


    Sharon · 28/07/2020 at 6:25 PM

    Hi Katrina2,

    Thank you so much, I’m glad you enjoyed the suggestions I provided in the post. Wow, 5 years of learning food, you must really know your nutrition so! It’s reassuring to have someone like yourself backup what I have posted and hopefully motivate others who read this to choose how to make smoothies healthy.

    If there’s any particular suggestions you have in terms of making smoothies healthy, I’d love to hear them.

    Best wishes,
