Oysters are uncommon but delicious molluscs that provide the human body with several unique nutrients and minerals, which result in great health benefits. Edible oyster is scientifically referred to as Ostreidea.
Oysters have a hard, greyish outer shell and they live in salty and brackish waters around the world. Oysters are a very nutritious and well-balanced food. There are more than 200 oyster species around the globe, only a fraction is edible. Commonly known edible oysters include Eastern oysters, Pacific oysters, European oysters, and Sydney Rock oysters among others.
Oysters are low in fat, high in protein, and an excellent source of omega-3 fatty acids, vitamins D, and B12.
Oysters provide a lot of benefits to the environments where they grow by improving water quality and providing habitat for different variety of organisms.
Good Source of Protein
Protein is a very essential part of human diet, and oysters are a very rich source. Proteins are often broken down by the body’s enzymatic activity and then reconstructed into usable human proteins in every part of the body. This ensures proper metabolic activity, tissue repair, cellular growth, muscle strength, and a wide variety of necessary aspects of human health.
Protect Heart Health
The rich potassium and magnesium content of oysters helps lower blood pressure and relax the blood vessels, thereby increasing the circulation and oxygenation of the blood and also reduces strain on the cardiovascular system as a whole. Also vitamin E in oysters help to increase the strength and flexibility of cellular membranes, which is the third level of protection against dangerous heart diseases.
Oysters have unprecedented levels of zinc which are important for proper growth and development of children and adults, as well as the maintenance of bodily function for people of all ages.
Increase Blood formation
Oysters are a very impressive source of iron which is a key component in the formation of red blood cells in the body and is the primary defense against anemia, also known as iron deficiency, which can lead to fatigue, cognitive malfunction, stomach disorders, and general muscle weakness.
Promote Healthy Bones
The high levels of calcium, phosphorus, zinc, iron, copper, and selenium in oyster contribute to increase the bone mineral density and durability.
Boost Immune Function
Vitamin C and E content, as well as other minerals that have antioxidant and anti-inflammatory properties contained in oyster help to defend the body against free radicals that are byproducts of cellular metabolism thereby boosting the immune system.
A Rare Food Source of Vitamin D
Vitamin D functions as a hormone rather than a traditional vitamin, and it plays a crucial role in keeping the human body healthy. It promotes bone health and modulates cells, and immune function. Sunshine is the single best source of vitamin D, but we can also get it from our diet, and oysters are one of the best sources.
Packed with Vitamin B12
Vitamin B12 is important for maintaining healthy blood cells and nerves, and it plays an essential role in DNA synthesis. Oysters offer far more of this nutrient than any typical meat, and only organ meats like liver can rival its B12 content.
