Spirulina: The Ancient Superfood Making a Modern Comeback
Have you heard about spirulina lately? This ancient superfood, classified as a cyanobacteria or blue-green algae, has been used for centuries as a food source in many countries. Spirulina is available in various forms such as capsules, tablets, and powder, and has even been incorporated into certain foods and beverages like energy bars, popcorn, and smoothies.
What makes spirulina so special? Well, for starters, it can thrive in extreme conditions that most other water-dwelling organisms cannot survive in. Cultivated in manmade or natural lakes, harvested, and freeze-dried, spirulina contains a whopping 60% protein content, making it a richer source of protein than most vegetables. It also boasts a good amount of beta-carotene, minerals, and gamma linolenic acid, an essential fatty acid.
While suppliers around the world promote spirulina's supposed health benefits, scientific evidence supporting these claims is lacking. Since spirulina is not regulated by the FDA, there's no guarantee that the product you buy is contaminant-free or contains the stated amount of spirulina.
Despite few reported side effects, spirulina can worsen symptoms of autoimmune disorders and interfere with blood clotting. It may also contain the amino acid phenylalanine, making it unsuitable for individuals with phenylketonuria (PKU).
If you're considering adding spirulina to your diet, it's essential to consult your healthcare provider, especially if you're taking other medications. While spirulina's potential benefits are intriguing, it's crucial to approach it with caution and prioritize your health and safety above anything else.
