What Seafood Is Bad for Diabetics? The Truth About Making Smart Choices

Is Any Seafood Bad for Diabetics?

The short answer is no. There’s no single type of seafood that people with diabetes need to avoid entirely.

 Most fish and shellfish are naturally low in carbohydrates and rich in protein, making them a good option for blood sugar balance. What matters more is how seafood fits into your overall eating pattern.

For example, eating seafood every day without including other sources of protein — like legumes, dairy, tofu, or eggs — can throw off your nutritional balance. And eating seafood that's been deep-fried or smothered in rich sauces can introduce unhealthy fats and hidden sugars.

Seafood can absolutely be part of a diabetes-friendly diet, as long as it’s one of several protein sources and prepared in a thoughtful way.

Cooking Methods That Can Make Seafood Less Diabetes-Friendly

Before you give up your favorite seafood dishes, consider this: it’s usually not the seafood that’s the problem — it’s how it’s cooked.

• Fried seafood (fish, shrimp, calamari): Often coated in breadcrumbs or batter made with refined flour. Also, it is typically deep-fried in unhealthy oils, adding excess fat and calories.
  
  
• Seafood with heavy sauces or breaded coatings: Includes buttery garlic sauces, sugary glazes, or creamy cheese toppings. Can turn a healthy protein into a high-fat, high-sodium meal.

In general, sticking to simpler cooking methods is the best way to keep seafood diabetes-friendly.

Healthier Ways to Prepare Seafood for a Diabetes-Friendly Meal

Now that we’ve talked about what to limit, let’s look at how to prepare seafood in a way that supports your health.

Grilled, Steamed, or Oven-Baked Options

Grilling or baking seafood with olive oil, lemon juice, garlic, or fresh herbs adds flavor without adding extra sugar or refined fats.

Steaming is another gentle method that keeps the texture tender and the flavor clean.

🐟Fatty fish like salmon are especially valuable for their heart-healthy fats. To learn more about why it’s often recommended for people with diabetes, read: Is Salmon Good for Diabetics?

What to Pair with Seafood

Seafood works best when it’s part of a complete, balanced plate. That means pairing it with fiber-rich foods like leafy greens, steamed broccoli, roasted carrots, lentils, or quinoa.

Avoid pairing seafood with refined carbs like white bread or creamy mashed potatoes. Instead, opt for whole grains, beans, or roasted vegetables for a satisfying, blood sugar-friendly meal.

By preparing seafood in simple ways and pairing it with whole, plant-based sides, you can enjoy it without worry.

How Often Should You Eat Seafood with Diabetes?

Experts generally recommend eating seafood about twice a week, especially options like salmon, sardines, and mackerel, which are rich in heart-healthy fats. 

Make sure to mix in other sources of protein, such as legumes, tofu, eggs, dairy, or poultry, so your meals stay nutritionally balanced throughout the week.

So yes, enjoy seafood regularly — just be mindful of how it fits into your overall weekly plan.
