Did you ever think that algae might be on your list of foods to try in the new year? The thought of it might take you by surprise, but the blue-green algae known as spirulina has gained a reputation as a popular health food in recent years. Spirulina commonly comes in supplement form as a powder or in tablets or capsules, but you can also buy it in raw form and use it in a variety of recipes—even sweet ones, where you might be surprised to find its mellow flavor complements fruit, maple, and honey quite nicely.
Specifically, spirulina is classified as cyanobacteria. It’s been harvested by humankind as a food source for centuries, primarily in Central America and Africa, where it grows naturally in lakes and ponds. Ancient Aztecs noted the positive health effects spirulina had in diets and even relied on it as a treatment for disease.
In its fresh, raw form, spirulina has a thick, creamy consistency similar to a dip or a spread. Taste wise, it has a mellow bitterness, similar to spinach and other greens, so it can easily be overpowered by other, stronger ingredients in a recipe. Its fat content also gives it a slight buttery mouthfeel, like avocado.
You might be surprised to learn that spirulina is an excellent source of protein—it is more than 60 percent protein by weight, much more than most fruits or vegetables. It’s also what’s known as a complete protein, meaning it provides all nine essential amino acids that your body can’t produce on its own (and therefore must get from food sources). This makes spirulina a good option for vegans and other people limiting their consumption of animal products. A single tablespoon of spirulina has about 4 grams of complete protein.
Another important nutrient for plant-based eaters to note is the iron found in spirulina. Spirulina has about 2 grams of iron per tablespoon—gram for gram, it’s a better source of iron than beef. Iron is necessary for producing red blood cells that carry oxygen to every part of your body.
Spirulina is also a great source of essential omega fatty acids, including gamma linolenic acid, which are good for your heart health. Its fat content will also help your body absorb its vitamins A and K, which are fat-soluble vitamins also found in spirulina.
Although the evidence to support claims about spirulina is limited, some early research shows that spirulina does in fact help lower blood pressure and regulate blood sugar. It also helps your body fight inflammation and infection.
It’s wise to be selective when buying spirulina because it’s classified as a supplement rather than as a food; therefore, it isn’t regulated by the Food and Drug Administration, so you don’t know the quality of the product you’re buying. Much of the processed spirulina you find on the market today has been grown in a lab, but there is some raw spirulina that has been harvested from the wild. In this case, there’s the risk the spirulina was grown in a polluted water source, through which it might have absorbed heavy metals. Buy spirulina from a trusted brand that is transparent about where it sources its spirulina. California and Hawaii are trustworthy places for spirulina growth—look for brands like Microingredeints Pure Organic Spirulina, Earthrise Spirulina, or Pure Hawaiian Spirulina.
When you bring spirulina home, whether you have it in raw or powdered form, you should always store it in a cool, dark place away from sunlight (such as your fridge). Spirulina even freezes nicely, though if you have an open package, be sure to remove any air before sealing it shut and putting it in the freezer.
Curious about how you can start using spirulina in your kitchen at home? Once you get a sense of how spirulina tastes and how it complements other foods, you’ll be able to get creative with using it in many of your favorite recipes. Here are a few to get you started:
