Diabetic patients can generally eat seafood in moderation, but they need to pay attention to cooking methods and portion sizes.Seafood is rich in high-quality protein, unsaturated fatty acids, and various minerals, which are helpful for blood glucose control. However, some high-cholesterol seafood should be chosen carefully.
The high-quality protein in seafood helps maintain muscle mass, delays gastric emptying, and reduces postprandial blood glucose fluctuations.Deep-sea fish such as salmon and cod contain omega-3 fatty acids, which can improve insulin sensitivity.Although crustaceans like shrimp and crab are high in cholesterol, studies show that dietary cholesterol has limited impact on blood cholesterol levels, and moderate consumption does not significantly increase cardiovascular risk.
It is recommended to use low-oil cooking methods such as steaming and boiling, and avoid frying or cooking with high-sugar sauces.Seafood can be eaten 2–3 times a week, with each portion controlled at 100–150 grams, and it should be counted toward the total daily protein intake.
Diabetic patients with hyperuricemia should limit high-purine seafood such as hairtail and sardine.Those with abnormal thyroid function should control the frequency of eating iodine-rich seafood such as kelp and laver.Patients with seafood allergies or impaired renal function should adjust their intake according to medical advice.Ready-to-eat seafood products may contain added sugar or sodium, so the nutrition label should be checked carefully when purchasing.
Diabetic patients are advised to eat seafood during periods of stable blood glucose, paired with vegetables and whole grains for balanced nutrition.Monitor postprandial blood glucose responses regularly and adjust the diet plan according to individual tolerance.Seek medical attention promptly if any adverse reactions occur.
