Protein-rich Oysters Provide the Good Fats

Oyster Nutrition: Fat

What is fat?

Fats or Lipids are either solid = saturated or liquid = unsaturated. Solid lipids contain more saturated fatty acids which are long chains of carbon and hydrogen atoms with one oxygen molecule at the end. Unsaturated fatty acids are missing one hydrogen pair and polyunsaturated are missing more. Insoluble fats in water require the liver to produce bile for digesting these bad fats.

Our bodies need fats for the digestive system to function but they can be very harmful. This is where high cholesterol comes into play, too many bad saturated fats leads to excess cholesterol which are then deposited onto our artery walls, reduces blood flow, and ultimately resulting in heart attacks and strokes.

Oyster Fat

These glorious protein-rich oysters come packing the good fats! Like olive oil, unsaturated fats provide many benefits such as reducing blood pressure and cholesterol. Most seafood are predominately protein and could not survive in cold waters if their fats were solid or saturated.

One medium east coast raw oyster, around 3.5 ounces provides 3 grams of fat. That means a dozen oysters provide 36 grams of fat. So, if you consume 1,500 calories on your weight-loss diet, you'll want between 42 and 58 grams of fat daily;, whereas a person eating 2,000 calories would consume between 56 and 78 grams of fat.

Oysters are the best source of protein with the good fats. Eat smart. #EatMoreOysters

Oyster Reproduction 101

One of the most commonly asked questions I receive while shucking oysters at parties are, how do oysters reproduce?

Very differently from you and I. Oysters are not exactly male or female. They are protandric which means they can change from male to female over their life. Oysters start off as male and then turn to female for the majority of their lifespan.

During an oysters spawning season, the young male releases his sperm and the older females release their eggs. Sometimes up to hundreds of million eggs. One the met they develop larvae.

Larvae takes 6 hours to develop and a few weeks to settle into another oyster shell or rocky place. Now they are spat and take one year to mature. Once mature they can begin reproducing yet not always ready to be harvested for consumption.
