The Glycemic Index of Shrimp and Seafood for Diabetics

The Glycemic Index of Shrimp and Other Seafood for People with Diabetes

For people with diabetes, monitoring the glycemic index (GI) of foods is an important way to help manage blood sugar levels. The glycemic index measures how much and how quickly a food raises blood glucose levels. Foods that rank high on the GI scale cause rapid spikes in blood sugar, while low GI foods cause a gradual rise in blood glucose.

Seafood can be a healthy part of a diabetes diet, but it's important to understand how different types affect blood sugar. This article explores the glycemic index of shrimp and other popular seafood choices for people with diabetes.

The Glycemic Index of Shrimp

Shrimp has a low glycemic index, meaning it has minimal effect on blood sugar levels. The GI of a 3.5 ounce (100 gram) serving of boiled shrimp is just 5, which is considered very low.

The low carbohydrate content of shrimp is responsible for its low GI rating. Shrimp is almost entirely protein, providing over 20 grams in a 3.5 ounce serving. It contains less than 1 gram of digestible carb per serving.

Due to its high protein content and low GI, shrimp is an excellent choice for those looking to control blood sugar. Protein foods like shrimp help blunt the blood sugar response of carbohydrate foods when eaten together as part of a balanced meal.

Comparing Shrimp to Other Seafood

Here is how the GI of shrimp compares to other popular types of seafood:

• Salmon: also low GI (under 10)
• Tuna: low GI (under 55)
• Cod: low GI (under 55)
• Halibut: low GI (under 55)
• Snapper: low GI (under 55)
• Tilapia: medium GI (56-69)
• Crab: medium GI (56-69)
• Lobster: medium GI (56-69)
• Clams: high GI (70 or more)
• Oysters: high GI (70 or more)

As shown above, most types of lean fish and shellfish tend to be low or medium GI foods. So along with shrimp, fish like salmon, tuna, cod, halibut, and snapper make excellent choices for diabetes diets.

While seafood is lower in carbs than many other protein foods, the GI can vary substantially between types. Clams and oysters are higher GI options due to their higher carbohydrate content.

Benefits of Shrimp for Diabetes Management

Here are some of the top reasons why shrimp is one of the best seafood choices for managing diabetes:

• Low carb: With less than 1 gram digestible carb per serving, shrimp won't spike blood sugar.
• High protein: The protein in shrimp promotes steady, long-lasting energy and keeps you feeling full.
• Nutrient-rich: Shrimp provides niacin, selenium, vitamin B12, and antioxidant carotenoids like astaxanthin.
• Heart healthy: Shrimp contains omega-3 fatty acids and may help lower triglycerides.

Shrimp is also very versatile and can be prepared in a variety of delicious ways that fit a diabetes eating pattern.

Tips for Choosing and Preparing Shrimp

Here are some tips for selecting and preparing shrimp:

• Opt for wild caught or sustainably farmed shrimp.
• Choose raw, frozen, or canned shrimp with no added sauces or sugars.
• Avoid breaded or fried shrimp which add carbs and fat.
• Steam, grill, or stir fry shrimp with healthy veggies and spices.
• Incorporate shrimp into salads, Buddha bowls, kebabs, and tacos.

Watch out for chilled shrimp or seafood salad drenched in mayo-based dressings, as these can be high in refined carbs and unhealthy fats. Enjoy shrimp in moderation along with a balanced diabetes diet to properly manage blood sugar.

Incorporating Seafood into a Diabetes Diet

Beyond just shrimp, seafood in general offers many benefits for those with diabetes. Here are some tips for eating more seafood as part of a healthy diabetes diet:

Eat 2-3 Servings of Seafood Per Week

Current dietary guidelines for people with diabetes recommend consuming 2-3 servings of seafood per week. A serving is about 3.5 ounces of fish or shellfish cooked.

Enjoying a few servings of seafood weekly provides protein, healthy fats, and important nutrients like selenium, iodine, vitamin D, and omega-3s. It can also help reduce cardiovascular risk factors like high blood pressure and triglycerides.

Vary Your Choices

For best health, experts recommend eating a variety of different seafood rather than always eating the same type. Try to eat both fatty and lean fish.

Some examples of leaner fish include cod, tilapia, flounder, and sole. Fattier fish like salmon, mackerel, sardines, trout and tuna offer heart healthy omega-3s.

Incorporate both finfish and shellfish like shrimp, clams, oysters and crab. Varying your seafood choices helps minimize any potential contaminants and provides a mix of nutrients.

Watch Portion Sizes

Its important to keep portion sizes of protein foods like seafood reasonable as part of a balanced plate. Here are some suggested single portion sizes for common types of seafood:

• Fish fillet or steak: 4-6 ounces
• Shellfish: 4-6 ounces
• Canned tuna: 3-4 ounces

Limit high fat sauces or fried coatings that can increase calories. Measure portions using a food scale or compare to the size of your palm.

Pair with Non-Starchy Vegetables

When eating seafood, be sure to balance it with plenty of non-starchy vegetables, salad greens, and other fiber-rich foods. Vegetables provide important nutrients with minimal effect on blood sugar.

Good veggie choices include broccoli, carrots, spinach, greens, peppers, mushrooms, zucchini, cabbage, and cauliflower. Non-starchy veggies help satisfy hunger and keep blood sugar stable.

Key Takeaways

• Shrimp has a very low glycemic index of just 5, making it an excellent choice for managing diabetes.
• Fish, shellfish, and seafood are typically low or medium glycemic index foods.
• Shrimp provides protein, nutrients, and heart healthy omega-3s with minimal carbs and calories.
• Aim to eat 2-3 servings of varied seafood per week as part of a balanced diabetes diet.
• Pair seafood with non-starchy vegetables and watch portion sizes for best blood sugar control.

Incorporating nutritious seafood like shrimp into your meal plan can provide many benefits for diabetes management and overall health.
