The Incredible, Edible Algae

Mmm, algae. No, really — it could be your next superfood, if you grow it the way Aaron Wolf Baum does. He’s an algae scientist who was studying alternative fuels before he decided he’d rather fuel people. He uses Spirulina, a type of blue-green algae, and says a spoonful — of which he eats up to 10 per day — approximates the nutrients of a whole salad in your diet. Spirulina is notable for its lack of cellulose, says Baum, making it easy for the body to absorb. Plus, it’s rich in protein and other vitamins and minerals.
