Oysters Are the Bomb!

Oysters are bivalve molluscs that live in marine or brackish habitats and are the most common farmed shellfish. Oysters depending on its kind can be consumed cooked or raw as delicacy, can be harvested for pearl production or even used as decorations.

Oysters are nutrient dense. They are an exceptional source of iron, calcium, zinc, vitamins A, B12, and C and selenium. The amino acids in oysters are rich that they can trigger increased levels of sex hormones. The high amounts of zinc in oysters aid in the production of testosterone considering them to be an aphrodisiac.

Oysters are free from environmental toxins such as mercury. The selenium that oysters have binds with mercury that protects the body from harm.

The shelf life of oysters can last up to weeks. Oysters can be eaten raw, grilled, smoked, boiled, baked, fried, steamed or stewed.
