What Kind of Seafood Is Considered Healthy for Diabetics and Why?

How seafood benefits individuals with diabetes depends on the type of food they eat. Here is an overview of the health benefits of the best diabetes-friendly seafood in our shop.


Diabetes affects cardiovascular health at various levels, but the most important is the influence on cholesterol levels and blood pressure. Eating foods rich in omega-3 fatty acids might control your cholesterol and blood pressure. Containing all the essential nutrients like vitamin A, vitamin C, calcium, iron, and protein, consuming salmon brings a lot of health benefits.

If you're wondering which types of salmon are suitable for diabetics, our Wild Alaska Coho Salmon and Norwegian Salmon are some of the best. Salmon is not only known for being rich in high omega-3 but is also categorized as oily fish, which is considered to lower the risks of cardiovascular diseases.


Eating a diet rich in proteins is highly recommended for people with diabetes. Thus, our Wild Alaska Black Cod is a perfect choice if you are looking for the best seafood options for people with diabetes. 

One serving contains 30 grams of protein. Only one serving of our Wild Alaska Black Cod will give your body almost half the recommended daily protein intake, between 77 and 116 grams for people weighing 170 pounds.

In addition, cod is low in carbs, rich in omega-3, and has a limited amount of cholesterol. The Wild Alaska Black Cod contains other essential nutrients, like vitamin A, calcium, iron, and heart-healthy fats.


Containing protein, omega-3 fatty acids, and vitamin D makes tuna another beneficial seafood for people with diabetes. Namely, these nutrients are essential for people with elevated blood sugar and cholesterol levels.

In our shop, you can find different types of tuna, including:


Trout is helpful for people who have type 2 diabetes. The American Diabetes Association recommends eating rainbow trout and other fish high in omega-3 fatty acids at least twice a week.

Additionally, trout is an excellent option because it is low in carbs (almost 0%) and has vitamins A and C, calcium, and iron. One serving of our Rainbow Trout Fillets also has 17 grams of fat, of which 12.5% are saturated fats. Most importantly, you will get a product fed with a plant-based diet, making it free of antibiotics and additives.

Ultimately, the trout's healthy fatty acids and sodium suit your cardiovascular health. They might help regulate your blood pressure and improve your heart's health, essential for people with diabetes.

Shrimp can also be your meal of choice if you have diabetes. Generally, they are low in carbs and calories but high in protein and omega-3 fatty acids. While shopping at KnowSeafood, you will come across different types of shrimp, such as:

If you are looking for no-fat seafood for your diabetes diet, the Colossal shrimps, both cooked and raw, have no saturated and trans fats. Another vital nutrition fact about Colossal shrimps is that one serving has more than 20 grams of protein and no carbs.


Lobster Tails are one of the best seafood types suitable for people with diabetes. They have a sweet taste yet are low in carbs. Our Lobster Tails have more than 50% protein per serving, which can help you reach your daily recommended intake.

Another reason why lobster is good for diabetes is that it contains calcium, which has a crucial role in improving insulin sensitivity.


Because of its nutrients, like selenium, magnesium, zinc, iron, and potassium, haddock regulates the heart rate. Another reason it is a good choice for people with diabetes is that it is a lean source of protein. It is low in carbohydrates, which means it has minimal to almost no impact on blood glucose levels.

Our Wild North Atlantic Haddock is packed with vitamin D, omega-3 fatty acids, and minerals such as potassium and sodium. All of these should be essential to your diet if you have diabetes.


Scallops contain all the nutrients for a healthy and balanced meal for diabetics, especially our Diver Caught Bay Scallops and Wild Sea Scallops, which have low fat but are high in protein. And, like the other types of seafood, they are rich in omega-3 fatty acids.

Our scallops are never processed and don't contain additives and preservatives, making them healthy.
