About this recipe: I recently bought a smoothie maker and did some extensive research about the best combination. I eventually settled on this recipe since it contains all the necessary nutrients you need for a healthy diet, and it tastes pretty damn good. I admit that fruits contain sugar so they are not ideal for those trying to lose weight, but the recipe only contains a small quantity of them and they are needed for their nutritional value. It's not as if you will gain 100 pounds by eating this smoothie once per day. You obtain an immense amount of vitamin A, C and D as well as potassium and magnesium from this recipe. Also, essential fatty acids are obtained from the avocado and walnuts to help your body fully absorb the vitamins (mostly vitamin A).
Depending on how thick you like your smoothies, you can increase or decrease the amount of almond milk. I avoid adding ice since it will dilute it slightly. Instead I finish my smoothie for the day, prepare another, then put it in the fridge until the following day.
I will also add that I was suffering from constant cramp in my calf area while asleep in which I would wake up in agony throughout the night. After 3 days of drinking this smoothie I no longer have any cramp at night, probably due to the potassium (something most people are deficient in).
I will also add that bananas do contain potassium but you would need to eat 12 a day to get your recommended dose, whereas kale packs way more in it.
