What it is: There are more than 4,000 species of the nutrient-rich algae Rhodophyta, which gets its red color from the pigment phycoerythrin. It’s an important component of food (like nori) and cooking in Japan, where it has been cultivated for over 300 years.
Benefits: Because red algae photosynthesizes and lives in very deep waters, it develops high levels of protein and vitamins, including vitamins B6 and B12, iron, and potassium. Sulfated polysaccharides, isolated from many red algae, may have antiviral and immune-boosting activities that could help inhibit viruses, such as herpes and influenza. Research shows that one type of red algae called Callophycus serratus has potential to fight cancerous cells and bacteria. Plus, deep-sea-cultivated algae’s antioxidants may lessen the effects of age-related diseases.
