5 FACINATING FACTS YOU DIDN’T KNOW ABOUT OYSTERS

Oysters are often seen simply as a seafood treat, but they’re much more than a gourmet indulgence. According to Adel Assal, owner of Oyster’s Seafood, these shellfish play a vital role in both environmental conservation and human nutrition. Here are five incredible facts that most people don’t know.
1. They are the sea’s natural filters
These shellfish act as natural filtration systems, removing pollutants such as nitrogen, algae, and sediment from seawater. Each can filter up to 50 gallons of water daily, making them essential to healthier, clearer marine ecosystems. Their filtering ability also improves oxygen levels and promotes biodiversity.
2. Oysters are nutritional powerhouses
Often labeled a superfood, they are rich in:
-
Zinc – vital for immune health and cell repair
-
Vitamin B12 – supports brain function and energy levels
-
Omega-3 fatty acids – essential for heart and mental health
Surprisingly, a single oyster can provide up to 400% of the brain’s daily B12 requirement. Their impressive nutritional profile makes them one of the healthiest seafood options available.
3. Their taste depends on their place
Just like wine has terroir, they have “merroir”—a term that describes how an oyster’s environment affects its flavor. Elements such as water salinity, temperature, and local vegetation impact each oyster’s taste and texture. For instance, oysters from saltier waters taste brinier, while oysters from estuaries often taste creamier.
4. They are gender fluid
They are sequential hermaphrodites, which means they can switch between male and female based on environmental needs. This remarkable trait ensures reproductive balance in their population and enhances their adaptability in changing conditions.
5. Their history is rich
These shellfish have been consumed by humans for over 2,000 years. In 19th-century New York City, they were sold on the street as commonly as hot dogs are today. Now, in Lebanon, Oyster Seafood is reviving this tradition by bringing oysters to local pop-ups, offering them fresh and raw, the way they’ve been eaten for centuries.
From supporting cleaner oceans to offering exceptional nutrition, these shellfish are among the most versatile and underappreciated organisms in the sea. As Oyster Seafood continues to bring fresh oysters to Lebanese tables and events, they hope to inspire a deeper appreciation for this remarkable shellfish.
