About Raw oyster

Raw oysters are bivalve mollusks found in both saltwater and freshwater environments, often harvested from coastal regions such as North America, Europe, and Asia. They are a staple in many cuisines, particularly those of France, Japan, and the United States, and are typically served fresh on the half shell with lemon, vinegar, or mignonette sauce. Oysters are an excellent source of high-quality protein and provide a wealth of nutrients including zinc, vitamin B12, iron, and omega-3 fatty acids. A standard serving of 6 raw oysters (approximately 100g) contains about 68 calories, 7g of protein, and 2g of fat, making them nutrient-dense and low in calories. Their subtle briny flavor and firm texture have made them a delicacy worldwide.
