As we ponder future food sources—often citing insects—microalgae like spirulina deserve attention. This spiral-shaped blue-green algae earns its 'food of the future' reputation from its exceptional nutritional profile, packed with vitamins and minerals. Low in calories and now produced industrially, spirulina is gaining popularity worldwide. Here are four key insights into this powerhouse algae.
Spirulina is a blue-green microalga that thrives in warm environments. While its natural form might not look appealing, it's a star ingredient in trendy dishes like Instagram-famous blue mermaid toast. Today, producers cultivate it in ponds globally, harvesting it for drying or fresh sale.
Dubbed a superfood for its impressive benefits, spirulina aids detoxification, cuts calories in meals, and boasts potent antioxidants that combat free radicals, support skin health, and reduce disease risk. Athletes value it for easing soreness and aiding muscle recovery. Rich in iron, complete proteins, and all essential amino acids—typically found in meat—it's an ideal vegetarian alternative, even during pregnancy.
Spirulina works as a short-term boost or daily supplement to address deficiencies. Available as flakes, powder, tablets, bars, or fresh, aim for 2-5 grams daily, 20 minutes before meals. Start low to avoid side effects like diarrhea, gradually increasing intake. Fresh spirulina shouldn't taste bitter; blend it into recipes if needed. Prices: €19.85 for 600 tablets at Jolivia; €10.95 for 200 at Nat &Form (E.Leclerc); €15-16 for 100g flakes or powder from Spirulina de la Côte Bleue.
