Seaweeds grow in abundance in the oceans, many of which are edible and safe for human consumption. They have been documented to contain many of the essential nutrients such as omega-3 fatty acids, amino acids, vitamins, minerals, and bioactive compounds. For many years, seaweeds have also been cultivated and utilized directly as food for humans or as feed to produce food for human consumption. Since seaweeds grow in many climatic conditions globally, their cultivation has minimal impact on the environment. Seaweeds are increasingly recognized as a sustainable food source with the potential to play a major role in providing food security worldwide. Although seaweeds are part of the diet in many Asian countries and some European nations, there are some challenges in terms of their incorporation into the general diet in many places globally. Innovation in food technology and culinology can help make seaweeds desirable organoleptically to increase their consumption.
