Rapidly increasing human population is creating food security problems. Over 2 billion people are suffering from one or more forms of malnutrition. Even where food might be adequate, without balanced food, people cannot be healthy. Poorer countries and communities are encountering malnutrition due to lack of food or inadequate macro nutrients such as energy and protein, and micronutrient deficiencies such as Vitamins A, D, and minerals e.g. Calcium, Iron, Zinc, etc.). At the same time, in rich countries and among rich people obesity is another problem caused by imbalanced diet. From health point of view, seafood or aquatic food is the best source of protein, which contains a good profile of essential amino acids. However, many people are not aware of this fact and seafood is still not consumed due to different taboos and traditional/cultural barriers. As a result, it has been difficult to reduce malnutrition in some countries.
