    How would algae contribute to the future of food? There is an increasing interest in seaweed, a common name for macro marine algae such as brown, red, and green algae. Moreover, algae may be able to help to future food security since they are rich in nutrients as well as protein content. They could be used in many human diet areas including snacks, sushi, salads, soups, and vegetarian protein source.

    One example is red algae species Porphyra yezoensis that is commonly used in sushi rolling and contains about 47% protein content.
