What Makes This Spirulina Smoothie Healthy?
This spirulina smoothie is packed with vitamins and antioxidants that can actually make you feel better. Itโs more than just another detox smoothie. Letโs take a look at what makes it a healing drink:
Apples โ we all know an apple a day keeps the doctor away. Apples are packed with fibre, vitamins C and K, and potassium.
Coconut water โ rich in antioxidants, vitamin C and protein.
Guava โ rich in antioxidants, vitamin C, potassium and fiber.
Spirulina โ may very well be the most nutritious food on the planet.
White grapes โ high in vitamins C and K.
Lime โ important antioxidant with plenty of vitamin C
What Is Spirulina?
Known today mostly as a very popular supplement, spirulina is actually a naturally occurring alga that grows in fresh and saltwater. Research has shown that its consumption goes all the way back to the ancient Aztecs, but it was actually rediscovered and popularised by NASA, who proposed it could be grown in space as a supplement for astronauts.
Is spirulina healthy?
Spirulina may be the most nutritious food on the planet, packed with a range of nutrients.
Dried spirulina (spirulina powder) contains about 60 to 70 percent protein. Itโs actually considered one of the few plant-based sources of complete protein. This means that it contains all essential amino acids that your body needs but canโt produce on its own, which makes it the perfect supplement for vegans. Itโs also a great source of calcium, iron, magnesium, and vitamins A, E, and K.
Can you taste spirulina in the smoothie?
Eaten directly, spirulina doesnโt have the most pleasant taste โ it is seaweed after all! But, when mixed with other ingredients, the taste of spirulina is completely undetectable. This smoothie tastes a lot like apple juice with a tangy hint of lime.
What is the difference between green and blue spirulina?
Iโve made this smoothie with both blue and green spirulina, and they both taste amazing and both are very high in antioxidants. The spirulina you can see in the photos here is blue spirulina.
Green spirulina, the alga, contains a phytochemical called phycocyanin. When phycocyanin is extracted from the alga, we call it blue spirulina.
Blue spirulina is actually just one compound of green spirulina, which is what makes green spirulina a much better source of vitamins, minerals, and protein. Blue spirulina is essentially just phycocyanin, which is a powerful antioxidant, but it lacks some of the other nutrients that get removed when the compound is extracted from the green alga.
One of the benefits of blue spirulina is that it has an even milder taste and you can easily add more of it to a smoothie without risking the seaweed taste coming through.
Is Coconut Water Really Good for You?
Hereโs another trendy ingredient! Can you replace it with water? Absolutely, but youโll be doing yourself a huge favour if you donโt. Hereโs why you should give coconut water a try (if you havenโt already):
- Excellent source of vitamin C, magnesium, manganese, potassium, sodium and calcium
- Rich in protein โ with 2 grams of protein per 46 calories, itโs actually one of the most protein-rich fruit juices in the world (crazy as it seems, but coconut is botanically considered a fruit rather than a nut)
- Has antioxidant properties
You can drink coconut water directly from the coconut. If this doesnโt seem feasible (and when youโre making a smoothie it isnโt), you can use bottled coconut water. However, make sure to read the ingredients to verify it is 100% coconut water, as some brands add sugar and flavouring agents.
If you really donโt like the taste, you can still omit it from the recipe. Substitute it with water, or your favourite plant based milk (I donโt recommend using cowโs milk in this smoothie, because the taste simply doesnโt go well with the rest of the ingredients).
What Kind of Apples Should I Use?
Any kind, but I find this smoothie works best with sweet apples, such as Gala, Fuji or Red Delicious.
Extra Tips to Make Sure Spirulina Smoothie Turns Out Well for You
- Donโt worry if you canโt find guava. You can simply use guava juice.
- Use a bit more lime if you like the slightly sour, refreshing flavour.
- Use 1 cup of coconut water to make this a thick smoothie, or 2 cups for a juice-like texture.
