Six Health Benefits From Eating Oysters: The Pearls of the Sea

Written by Isabella Boston.

Oysters are freshwater bivalve mollusks made up of a shell with two hinged parts. They feed and process water with their gills and cilia. Oysters have internal organs, a small heart, and no central nervous system.

Because Oysters lack a central nervous system, it is unlikely they feel pain and most vegetarians feel comfortable eating them. While some oysters have two sexes, they all contain both eggs and sperm.

Oysters have a simple anatomy and do not have a central nervous system. “Oyster Anatomy” by Louisiana Sea Grant.

3. Promotes Heart Health ~ Oysters reduce the harmful plaque that accumulates in the arteries and on the artery walls. In addition, the high amounts of potassium and magnesium contents in oysters helps to lower blood pressure and relax the blood vessels. This plays an important role in combatting the risk of a stroke and a heart attack.

Potential Health Risks From Eating Oysters

Since most people eat oysters raw, there are some rare health risks. Oysters can contain a harmful bacteria known as Vibrio Bulnificus. This bacterium is linked to serious illnesses and can even be fatal.

There is no way to know if the oysters you consume have been contaminated, because there is no difference in the way they look, smell, or taste. Symptoms usually begin 24 to 48 hours after you have eaten the infected oysters and may include nausea, chills, fever, vomiting, diarrhea, and even shock.

Those most at risk are people with diabetes, liver disease, and cancer. Heavy drinkers are also at greater risk.

If you or anyone else you know experiences these symptoms after eating raw oysters, please seek emergency care immediately.

In conclusion, oysters are a nutritious seafood and global cuisine that can provide you with many health promoting benefits.
