Oysters Nutritional Facts

Oysters are from the bivalve mollusks family that usually live in marine and saltwater habitats. They are categorized as bivalves because of their two highly calcified shells that enclose the flavourful meat.

Generally, oysters are of different types, including pearl, saddle, feather, spiny, dimyarian, and windowpane oysters, and have their importance. Most edible oysters have the same salty taste and are considered a delicacy worldwide.

  • Oysters are highly nutritional and have several health benefits because of their very well-known purported aphrodisiac qualities. The edible slimy and plump part is protected in the calcified hard shells that need to be cracked open for eating the oyster.
  • Oysters are pretty low in calorie content but are rich in other essential nutrients such as proteins, vitamins, minerals, and healthy fats.
  • Oysters are an excellent source of protein containing all nine amino acids in abundance, enabling the body to stabilize hunger, control blood sugar levels, reduce the risk of heart disease, and promote weight loss.
  • Oysters are an abundant source of omega-3 fatty acids that helps in maintaining heart health, sharp brain functioning, and regulating body inflammation. Regular and adequate intake of omega-3 fats can lower the risks of heart disease and diabetes in your body.
  • They are rich in Vitamin B12, which is vital for maintaining a healthy nervous system, metabolism, blood cell formation, and preventing deficiency disorders.
  • Zinc proves necessary in improving immune health, boosting metabolism, and promoting cell growth. A small amount (50 g) of oyster consumption can provide you with 300% of the RDI of zinc.
  • Vitamin D is essential for cellular growth, bone strengthening, maintaining body temperature, and boosting immunity. Many people in the colder regions fail to get this vitamin regularly and suffer from deficiency disorders.
  • Oysters are rich in iron, which helps the body synthesize more hemoglobin and myoglobin to assist oxygen transport in the blood properly.
  • The presence of a mineral called selenium is helpful for thyroid functioning, managing oxidative stress, and boosting metabolism. It is also a powerful antioxidant that prevents cellular damage in the body. These benefits eventually lower the risk of chronic diseases like cancer, mental deterioration, and heart diseases.
  • Oysters also have a unique antioxidant, recently discovered and called DHMBA. It is potent in combating oxidative stress and the possibility of chronic diseases, improving liver health, lowering harmful cholesterol levels, and benefiting heart health.
  • Apart from all the advantages of oyster consumption, the only significant disadvantage is the presence of harmful bacteria and viruses in raw oysters that may cause harmful infections and harm the body severely. To avoid any potential infections, the way to tackle this issue is to cook the oyster before eating.

Health Benefits Of Oysters For Dogs

Oysters are highly nutritional for humans, as we discussed previously, but it also contributes very well to the nutritional requirements of dogs. Some primary health benefits provided by oysters that help dogs to maintain good health are:

  • Eating oysters frequently can gradually help build a robust immune system and help the body fight against common disorders, fatal diseases, and infective problems. Including seafood like oysters in the dog’s diet can enhance their immunity to a great extent.
  • As their age increases, dogs lose their cognitive abilities, joint strength, and muscular health. This weakened body framework can cause several diseases and affect their health severely, but eating oysters would ensure strong bones, muscles, and joints in dogs. The protein and zinc in oysters are mainly responsible for improving muscle and joint health.
  • Some dogs have reduced energy levels due to specific reasons which ultimately make their body weak, lazy, and obese. In these circumstances, where your dog is feeling unenergetic at all times, oysters work as an energy booster supplementary food that provides instant energy to dogs.

Puppies can safely eat oysters and get all the nutrients in adequate amounts to ensure proper health. Dogs generally are allergic to most of the other kinds of seafood, so oysters prove to be a lifesaver among them for a rich nutrition-fueling diet.

Furthermore, oysters are also smooth in texture and consistent in nutritional value, due to which they don’t harm the sensitive digestion of puppies at all.

Moreover, puppies require lots of energy providing and growth-promoting foods in their early stage to help them have a good and rapid growth rate.

Can dogs eat smoked oysters?

Smoked oysters are usually available in packaged or canned form. They are processed through cooking, flavoring, and preservation with artificial additives. After that, they are exposed to the smoky aroma of the burning wood, and that’s how they acquire the smoked flavor.

The smoked variety of oysters are antimicrobial and act as antioxidants for inducing significant health benefits in the process.

Although smoked oysters seem to be an elegant delicacy for humans, they are not very safe for dogs in large quantities or frequently. They are not toxic and are the best food choices to feed your dogs.

However, you may feed your dog smoked oysters once in a while as occasional treats, but you mustn’t include it in their regular diet.

Can dogs eat oysters in oil?

Oysters cooked in oil by any method are not suitable for dog consumption. Frying the oysters in saturated oil can increase the fat content and calories to the recipe, which leads to rapid weight gain.


Preparing the oyster recipe with oil certainly makes way for flavored additives, seasonings, and chemically enriched ingredients to be used. These artificial spices and oil can make the oyster unhealthy for dogs and should be avoided entirely to prevent fatal disorders.

However, a light sauteing of oysters or briskly baking them can be beneficial instead of raw oysters. Raw mollusks can cause bacterial and viral infections to the consumers and can be fatal depending on the situation, so they are recommended to be avoided.

Proteins are vital for healthy muscular growth in dogs, while omega-3 fats boost overall health, prevent several diseases, and decrease organ inflammation.

Some dogs are allergic to chicken and fish, so oysters are a great alternative to these rich nutrients. Dogs are also fond of other seafood options like sardines, smelt, haddock, salmon, cod, and anchovies.

Are Oysters Bad For Dogs?

Oysters are essentially healthy for canines but should be included in the dog’s diet only in moderation. So it is excellent if you replace it with more nutritious alternatives for frequent consumption. However, oysters can be bad for dogs only because of the following reasons:

  • If they are fed in excess, the amount of zinc intake in the body increases and can lead to fatal problems such as diarrhea, unconsciousness, zinc poisoning, inflammation, nausea, and low blood pressure.
  • If you acquire raw oysters from marine water bodies, those are highly polluted and can potentially affect the aquatic wildlife with harmful toxins.
  • If the oysters are contaminated with a toxic alga called a dinoflagellate, that is harmful enough to cause fatal disorders like paralytic shellfish poisoning (PSP) in dogs.

Can dogs eat smoked oysters in oil?

They are to be avoided by your dogs because they are certainly not suitable for canine consumption because of the extra ingredients and processing done in the dish’s preparation.

How Often Can A Dogs Eat Oysters?

The ideal serving frequency is once or twice a month. Oysters are a great source of essential nutrients and are valuable for including in a dog’s diet. However, they must be considered occasional treats and not regular dietary options.
