The Good and Bad Health Effects of Eating Oysters

Updated on April 11, 2016

Oysters can offer an array of benefits on our health. But sometimes, this delectable, exotic food can also have a bad effect to our body. Find out more about the good and bad health effects of eating Oysters.

What Is an Oyster?

Oysters are a type of mollusk and classified as bivalve marine creatures because of their two-halve shells.

Oysters are large shellfish; they have rough and fluted shells that are fleshy and soft in texture. This exotic seafood is loaded with many health benefits and is important in our diet.

Oysters have unique flavors - from sweet to salty, these can be consumed in a variety of ways such as baked, fried, roasted, stewed, pickled, steamed, raw, canned and grilled to perfection.


But not everybody loves to eat oysters.

Some people avoid eating this delish, exotic food due to the perception that Oysters have high cholesterol content. But the truth is, Oysters actually contain only around 50 mg. of cholesterol per serving.

The mg recommendation of oysters in our diet is 300mg per day. Oysters can be enjoyed when taken in moderation by everyone.


THE HEALTH BENEFITS OF OYSTERS


Here are some benefits that we could get when eating oysters. You may think that it does not offer much help but the minerals found in this seafood also plays a vital role in our body.

  • Oysters are low in fat, cholesterol and calories but rich in amino acids. They trigger increased levels of sex hormones, testosterone and estrogen - that is the reason why they are called "Aphrodisiacs".

  • Oysters are high in protein. This protein contains high levels of tyrosine - an amino acid that is used by our brain to help regulate our mood and stress levels in brain.

  • Oysters are a good source of Vitamins A, B1 and B2, C, D and E.

  • Oysters also contain other vitamins and minerals such as manganese, calcium, iron, potassium, taurine, glucose, thiamine, riboflavin, niacin and magnesium.

  • Oysters are high in calcium. They can help strengthen bones and helps prevent osteoporosis.


  • Oysters help maintain the collagen in our skin and help retain the elasticity and firmness so as to delay wrinkles.

  • Oysters are a natural source of zinc. They assist in maintaining our sense of taste and smell, helps improve our immune system and helps inhibit the abnormal clotting which can lead to cardiovascular diseases.

THE DARKER SIDE OF OYSTERS


Oysters can offer an array of health benefits to our but we also have to take note that there are also "not-so-good" about them. This exotic food is not ideal for all diet plans so one has to watch when taking this seafood.

  • Oysters are relatively high is sodium so they are not really advisable to people with a heart disease or hypertension.


  • Oysters contain bacteria called "Vibrio". These bacteria can be found in raw oysters so it is much recommended to cook or grill them until well done. The bacteria can cause illnesses especially to those with weak immune systems.

    Pregnant women must put their oyster craving on hold due to the bacteria present that can cause illnesses.


  • Oysters are not also a good source of Omega 3. Omega 3 is essential fatty acids that play a vital role in brain function, joints and muscles as well as on our skin. The body can't make them that's why we rely on food to get them.


  • Oysters are not a very god carrier of dietary fiber. We need fiber to help ease digestion.


  • Oysters may cause stomach problems and may trigger gastrointestinal reactions and allergies.


Always remember that anything consumed in excess can really have a bad effect on our health. To balance the nutritional value, it is very advisable to take food in moderation.

Oysters Fun Facts:


  • True Oysters are found throughout the world's oceans - they belong to the family Ostreidae family. They are usually found in shallow waters and reefs.

    True Oysters are different from Pearl Oysters (those oysters which produces pearls and they belong to another family of bivalves).

  • Oyster's shell are oval or pear-shaped and the outer shell color is whitish-gray while the inside shell is porcelain white.

  • Oysters have extremely strong adductor muscles. They use it to close their shells when threatened.

  • Oysters reproduce by broadcast spawning when the water warms.

  • Oysters can change their gender one or more during their lifetime.

      First let me say you did a great job and your pictures are perfect. Now, I can say I read this hub because you wrote it...I am allergic to shellfish so really can't enter into the debate of eating or not eating oysters :) Even so, voted up, interesting and useful.

      unknownspy,

      This is really a great hub and I love your pictures. When I lived in the Baltimore area, I'd go down to the Inner Harbor sometimes and see people eating raw oysters at the seafood restaurants. I never could. What I do like are oyster omelettes which I had in Taiwan and get here in Thailand. Voted up as interesting and useful. Shared with followers and on Facebook. Also Pinning.

      Oysters are high in zinc so therefore; it's a high-libido food. I'm not too crazy about its taste, but recently, I ate them at Hooters and after a week, I noticed my nails were super long. voting up!

      Myz - Very interesting hub! I lived along the Gulf Coast for years, and a favorite dish was raw oysters on the half shell. People would load them up with horseradish and such, and then swallow without chewing. I always believed that if you had to cover up the taste that much, and you didn't like it enough to chew it, then why eat it? It never made any sense. I do remember my grandmother's oyster bread dressing and how grand it tasted. Great hub!

      My wife (a Filippina) will not let me eat oysters with my Filippino friends. Because 1 oyster - 1 shot of Remmy Martin. :))
