Seafood for diabetes

Last updated on September 21st, 2022 at 11:20 am

Diabetes affects millions of Americans every year. If you or someone you love has diabetes, you might wonder whether seafood is safe to eat.

Diabetes is a condition where blood sugar levels become too high because the body does not produce enough insulin (a hormone) or cannot properly use the insulin it produces. Insulin helps move glucose from the bloodstream into cells, where energy is produced. Glucose builds up in the bloodstream when the pancreas does not produce enough insulin or when the body becomes resistant to insulin. This buildup causes serious health problems such as heart disease, stroke, blindness, kidney failure, nerve damage, amputations, and death.

Seafood contains nutrients that are beneficial to diabetics. In fact, some studies show that fish oil supplements can reduce blood sugar levels. However, there are also risks associated with consuming certain types of seafood. For example, mercury levels in tuna can pose a risk to pregnant women and children. Therefore, it’s important to talk to your doctor before deciding whether or not to include seafood in your diet. 

Should Diabetics Eat Seafood?

Seafood is a great source of protein and nutrients, but some types contain high levels of saturated fat and cholesterol.

Which seafood has the lowest amount of these substances? The American Heart Association recommends limiting the consumption of foods containing saturated fats and cholesterol because they increase blood cholesterol levels. Saturated fats come from animal sources such as meat, dairy, eggs, and butter. Cholesterol comes from red meats, poultry, fish, shellfish, and organ meats.

Fish contains omega-3 fatty acids, which lower bad (LDL) cholesterol and raise good (HDL) cholesterol. Fish also provides other important nutrients, such as vitamin D, calcium, iodine, selenium, zinc, and iron. 

Low in trans and saturated fats

Maintaining a low cholesterol level as well as a healthy heart depends on a diet that is low in trans and saturated fats. That’s true for most of us, but especially those with diabetes. Thankfully, that fat you find in your seafood is unsaturated, and therefore healthy. 

A natural source of omega-3

Many of us understand by now that fatty acids such as omega-3s are essential to combating high blood pressure, cholesterol, and heart disease. Seafood is high in omega-3s, helping diabetics better manage their condition.

Shellfish decreases the risk of diabetes, obesity, and heart disease, and, at the same time, promotes healthy cholesterol levels.

Seafood precautions for diabetic

Certain types of seafood, however, should be avoided because they may cause an increased risk of high blood sugar levels.

Fish and shellfish are rich in omega-3 fatty acids which are essential for brain development, vision, heart function, and immune system health. Omega-3 fatty acid supplements are available at most grocery stores and pharmacies.

People with diabetes should avoid eating large amounts of seafood because of its high content of mercury, which can be harmful to their health. Mercury is a toxic substance that accumulates in the human body and causes severe damage to the kidneys.

People with diabetes who eat too much mercury may develop kidney damage. Therefore, they should limit their consumption of tuna, swordfish (or similar fish), king mackerel, and tilefish to no more than 12 oz/month.

Seafood is an excellent source of omega-3 fats, but it is also high in salt. Diabetics should limit their intake of seafood to six ounces per week to avoid increasing their blood pressure.
