Although I'm not a big fan of "green smoothies", this one is delicious and definitely one of my breakfast favourites. And it's great for Easter and St Patrick's Day!

Most smoothies are packed with sugar, unnecessary colourings or additives. This smoothie is not only low-carb but it's also made just from natural ingredients. It's VERY high in fibre, heart-healthy monounsaturated fat and potassium.

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

I'm off sugar, & fruit for a bit, so I used almond milk (unsweetened), added frozen
broccoli, almonds as well as flax seed powder, no whey for me, or the sweetner & vanilla, for now. Next time i'll try unsweetened cashew milk for more protein, it's a bit creamier too.


Sounds yummy, thanks for sharing your version! 😊


The smoothie looks great. Just wondering why you would use whey protein, which is really dairy, which causes inflammation. I have been using pea protein and it has 20g of protein in my shakes. Wouldn't that be a better option? Just wondering. Thanks!


Hi Nikki, you can use coconut milk instead. The reason I use raw dairy is that I like many others tolerate it quite well, it does not always cause inflammation. I don't snack on dairy but I do use it in recipes - paleo / primal approach 😊 I haven't tried pea protein yet but I do use egg white protein every now and then.


You're an idiot. There is nothing paleo or primal about another animal's milk. Our primal ancestors did not consume dairy.


You are rude and ignorant. Do yourself a favour and read more about raw full-fat dairy being primal - no one said anything about animal "milk".


I make a similar smoothie but take out the sweetener and add 1/2 an apple and 2 T. frozen mango. It tastes almost identical. It's this recipe, but without the kombucha.
Thanks for sharing!


Sounds delicious! Maybe not so low in carbs but it is paleo-friendly and I actually like the kombucha in it 😊


Forgot to add, this next batch I'm planning on adding a kiwi as well. I think a kiwi and mint flavor will go well together. -- greg


Sounds great to me! Have you thought of using almond milk instead? Most soy products come from GMO sources and contain estrogens.


Can't get mint where I am. Is there a substitute for that you could recommend?
Also, would cashews be an ok substitute for pistachios?


How about mint extract - can you find that? Or simply skip mint and use just vanilla extract. You can definitely use cashews or any nuts you like instead of pistachios.


Found some mint and substituted cashews for pistachios, and made a large batch. Added some honey, vanilla abstract, and artificial sweetener as well. Also, switched in soy milk for the water for more protein.
Man, that was really good! Gett'n ready to make a second batch.
Thnx! -- greg


Where is the calorie count?  I am guessing 400.


Calorie count is in the nutrition data table (energy = 493 kcal).


Oh my god this looks so good! I don't usually like green smoothies but I will have to try this one. The pistachio nuts sound like a great ingredient 😊


Thank you! Pistachios are the key ingredient in this recipe 😊


Delicious recipe and beautiful photos that make me drool 8-))


Thank you Kalyn!


Thanks for your help.  I have been wanting to start but am Ovo-Lacto Vegetarian. Thanks for sorting out fantastic options... this looks great!!


Hi Topher, I have a vegetarian diet plan that you can downloads here (free): - I hope this helps!
