Grouper is a saltwater fish with high nutritional value, of which varieties such as Eastern Star Grouper, Green Grouper, Mouse Grouper, Money Grouper, Tiger Grouper, and Leopard Star Grouper are considered delicious. Different varieties of grouper differ in terms of meat quality, number of bones, unsaturated fatty acid content, protein, amino acids and minerals. For example, eastern star grouper has tender meat with few bones and is loaded with unsaturated fatty acids, which are also helpful in preventing blood thickening. Green grouper has the highest protein content and higher Essential Amino Acid Index (EAAI), as well as a slightly higher fat content than other marine fish, but is rich in unsaturated fatty acids. Brown-spotted grouper has the highest zinc content, which helps promote brain protein synthesis and the development and refinement of the nervous system. Therefore, the best variety of grouper depends on personal taste and preference, as well as consideration of the body's nutritional needs. It can be purchased through community fresh food stores or online, and is delicious steamed.
