Category: Food > Spirulina
One of the most surprising foods with an exceptionally high protein content per calorie is spirulina, a blue-green algae often found in powdered form. This superfood packs about 60-70% protein by weight, making it one of the richest sources of protein available in nature. What’s more, spirulina is a complete protein, meaning it contains all essential amino acids that the human body cannot produce on its own. Beyond its impressive protein profile, spirulina is loaded with vitamins, minerals, antioxidants, and anti-inflammatory properties. Its nutrient density makes it a popular choice among vegans and health enthusiasts looking to boost their protein intake without consuming excess calories. Adding just a tablespoon of spirulina powder to smoothies or snacks can significantly enhance nutritional value while supporting overall health.
